69afef4af4 gpio updates for v6.9 
Serialization rework:
 - use SRCU to serialize access to the global GPIO device list, to GPIO device
   structs themselves and to GPIO descriptors
 - make the GPIO subsystem resilient to the GPIO providers being unbound while
   the API calls are in progress
 - don't dereference the SRCU-protected chip pointer if the information we need
   can be obtained from the GPIO device structure
 - move some of the information contained in struct gpio_chip to struct
   gpio_device to further reduce the need to dereference the former
 - pass the GPIO device struct instead of the GPIO chip to sysfs callback to,
   again, reduce the need for accessing the latter
 - get GPIO descriptors from the GPIO device, not from the chip for the same
   reason
 - allow for mostly lockless operation of the GPIO driver API: assure
   consistency with SRCU and atomic operations
 - remove the global GPIO spinlock
 - remove the character device RW semaphore
 
 Core GPIOLIB:
 - constify pointers in GPIO API where applicable
 - unify the GPIO counting APIs for ACPI and OF
 - provide a macro for iterating over all GPIOs, not only the ones that are
   requested
 - remove leftover typedefs
 - pass the consumer device to GPIO core in devm_fwnode_gpiod_get_index() for
   improved logging
 - constify the GPIO bus type
 - don't warn about removing GPIO chips with descriptors still held by users as
   we can now handle this situation gracefully
 - remove unused logging helpers
 - unexport functions that are only used internally in the GPIO subsystem
 - set the device type (assign the relevant struct device_type) for GPIO devices
 
 New drivers:
 - add the ChromeOS EC GPIO driver
 
 Driver improvements:
 - allow building gpio-vf610 with COMPILE_TEST as well as disabling it in
   menuconfig (before it was always built for i.MX cofigs)
 - count the number of EICs using the device properties instead of hard-coding
   it in gpio-eic-sprd
 - improve the device naming, extend the debugfs output and add lockdep asserts
   to gpio-sim
 
 DT bindings:
 - document the 'label' property for gpio-pca9570
 - convert aspeed,ast2400-gpio bindings to DT schema
 - disallow unevaluated properties for gpio-mvebu
 - document a new model in renesas,rcar-gpio

Pull gpio updates from Bartosz Golaszewski:
 "The biggest feature is the locking overhaul. Up until now the
  synchronization in the GPIO subsystem was broken. There was a single
  spinlock "protecting" multiple data structures but doing it wrong (as
  evidenced by several places where it would be released when a sleeping
  function was called and then reacquired without checking the protected
  state).

  We tried to use an RW semaphore before but the main issue with GPIO is
  that we have drivers implementing the interfaces in both sleeping and
  non-sleeping ways as well as user-facing interfaces that can be called
  both from process as well as atomic contexts. Both ends converge in
  the same code paths that can use neither spinlocks nor mutexes. The
  only reasonable way out is to use SRCU and go mostly lockless. To that
  end: we add several SRCU structs in relevant places and use them to
  assure consistency between API calls together with atomic reads and
  writes of GPIO descriptor flags where it makes sense.

  This code has spent several weeks in next and has received several
  fixes in the first week or two after which it stabilized nicely. The
  GPIO subsystem is now resilient to providers being suddenly unbound.
  We managed to also remove the existing character device RW semaphore
  and the obsolete global spinlock.

  Other than the locking rework we have one new driver (for Chromebook
  EC), much appreciated documentation improvements from Kent and the
  regular driver improvements, DT-bindings updates and GPIOLIB core
  tweaks.

  Serialization rework:
   - use SRCU to serialize access to the global GPIO device list, to
     GPIO device structs themselves and to GPIO descriptors
   - make the GPIO subsystem resilient to the GPIO providers being
     unbound while the API calls are in progress
   - don't dereference the SRCU-protected chip pointer if the
     information we need can be obtained from the GPIO device structure
   - move some of the information contained in struct gpio_chip to
     struct gpio_device to further reduce the need to dereference the
     former
   - pass the GPIO device struct instead of the GPIO chip to sysfs
     callback to, again, reduce the need for accessing the latter
   - get GPIO descriptors from the GPIO device, not from the chip for
     the same reason

75f4d93ee8 Merge branch 'for-6.9/cxl-einj' into for-6.9/cxl 
Pick up support for injecting errors via ACPI EINJ into the CXL protocol
for v6.9.

8039804cfa cxl/core: Add CXL EINJ debugfs files 
Export CXL helper functions in einj-cxl.c for getting/injecting
available CXL protocol error types to sysfs under kernel/debug/cxl.

The kernel/debug/cxl/einj_types file will print the available CXL
protocol errors in the same format as the available_error_types
file provided by the einj module. The
kernel/debug/cxl/$dport_dev/einj_inject file is functionally the same
as the error_type and error_inject files provided by the EINJ module,
i.e.: writing an error type into $dport_dev/einj_inject will inject
said error type into the CXL dport represented by $dport_dev.

9187210eee Networking changes for 6.9. 
Core & protocols
 ----------------
 
  - Large effort by Eric to lower rtnl_lock pressure and remove locks:
 
    - Make commonly used parts of rtnetlink (address, route dumps etc.)
      lockless, protected by RCU instead of rtnl_lock.
 
    - Add a netns exit callback which already holds rtnl_lock,
      allowing netns exit to take rtnl_lock once in the core
      instead of once for each driver / callback.
 
    - Remove locks / serialization in the socket diag interface.
 
    - Remove 6 calls to synchronize_rcu() while holding rtnl_lock.
 
    - Remove the dev_base_lock, depend on RCU where necessary.
 
  - Support busy polling on a per-epoll context basis. Poll length
    and budget parameters can be set independently of system defaults.
 
  - Introduce struct net_hotdata, to make sure read-mostly global config
    variables fit in as few cache lines as possible.
 
  - Add optional per-nexthop statistics to ease monitoring / debug
    of ECMP imbalance problems.
 
  - Support TCP_NOTSENT_LOWAT in MPTCP.
 
  - Ensure that IPv6 temporary addresses' preferred lifetimes are long
    enough, compared to other configured lifetimes, and at least 2 sec.
 
  - Support forwarding of ICMP Error messages in IPSec, per RFC 4301.
 
  - Add support for the independent control state machine for bonding
    per IEEE 802.1AX-2008 5.4.15 in addition to the existing coupled
    control state machine.
 
  - Add "network ID" to MCTP socket APIs to support hosts with multiple
    disjoint MCTP networks.
 
  - Re-use the mono_delivery_time skbuff bit for packets which user
    space wants to be sent at a specified time. Maintain the timing
    information while traversing veth links, bridge etc.
 
  - Take advantage of MSG_SPLICE_PAGES for RxRPC DATA and ACK packets.
 
  - Simplify many places iterating over netdevs by using an xarray
    instead of a hash table walk (hash table remains in place, for
    use on fastpaths).
 
  - Speed up scanning for expired routes by keeping a dedicated list.
 
  - Speed up "generic" XDP by trying harder to avoid large allocations.
 
  - Support attaching arbitrary metadata to netconsole messages.
 
 Things we sprinkled into general kernel code
 --------------------------------------------
 
  - Enforce VM_IOREMAP flag and range in ioremap_page_range and introduce
    VM_SPARSE kind and vm_area_[un]map_pages (used by bpf_arena).
 
  - Rework selftest harness to enable the use of the full range of
    ksft exit code (pass, fail, skip, xfail, xpass).
 
 Netfilter
 ---------
 
  - Allow userspace to define a table that is exclusively owned by a daemon
    (via netlink socket aliveness) without auto-removing this table when
    the userspace program exits. Such table gets marked as orphaned and
    a restarting management daemon can re-attach/regain ownership.
 
  - Speed up element insertions to nftables' concatenated-ranges set type.
    Compact a few related data structures.
 
 BPF
 ---
 
  - Add BPF token support for delegating a subset of BPF subsystem
    functionality from privileged system-wide daemons such as systemd
    through special mount options for userns-bound BPF fs to a trusted
    & unprivileged application.
 
  - Introduce bpf_arena which is sparse shared memory region between BPF
    program and user space where structures inside the arena can have
    pointers to other areas of the arena, and pointers work seamlessly
    for both user-space programs and BPF programs.
 
  - Introduce may_goto instruction that is a contract between the verifier
    and the program. The verifier allows the program to loop assuming it's
    behaving well, but reserves the right to terminate it.
 
  - Extend the BPF verifier to enable static subprog calls in spin lock
    critical sections.
 
  - Support registration of struct_ops types from modules which helps
    projects like fuse-bpf that seeks to implement a new struct_ops type.
 
  - Add support for retrieval of cookies for perf/kprobe multi links.
 
  - Support arbitrary TCP SYN cookie generation / validation in the TC
    layer with BPF to allow creating SYN flood handling in BPF firewalls.
 
  - Add code generation to inline the bpf_kptr_xchg() helper which
    improves performance when stashing/popping the allocated BPF objects.
 
 Wireless
 --------
 
  - Add SPP (signaling and payload protected) AMSDU support.
 
  - Support wider bandwidth OFDMA, as required for EHT operation.
 
 Driver API
 ----------
 
  - Major overhaul of the Energy Efficient Ethernet internals to support
    new link modes (2.5GE, 5GE), share more code between drivers
    (especially those using phylib), and encourage more uniform behavior.
    Convert and clean up drivers.
 
  - Define an API for querying per netdev queue statistics from drivers.
 
  - IPSec: account in global stats for fully offloaded sessions.
 
  - Create a concept of Ethernet PHY Packages at the Device Tree level,
    to allow parameterizing the existing PHY package code.
 
  - Enable Rx hashing (RSS) on GTP protocol fields.
 
 Misc
 ----
 
  - Improvements and refactoring all over networking selftests.
 
  - Create uniform module aliases for TC classifiers, actions,
    and packet schedulers to simplify creating modprobe policies.
 
  - Address all missing MODULE_DESCRIPTION() warnings in networking.
 
  - Extend the Netlink descriptions in YAML to cover message encapsulation
    or "Netlink polymorphism", where interpretation of nested attributes
    depends on link type, classifier type or some other "class type".

1f44039766 A moderatly busy cycle for development this time around. 
- Some cleanup of the main index page for easier navigation
 
 - Rework some of the other top-level pages for better readability and, with
   luck, fewer merge conflicts in the future.
 
 - Submit-checklist improvements, hopefully the first of many.
 
 - New Italian translations
 
 - A fair number of kernel-doc fixes and improvements.  We have also dropped
   the recommendation to use an old version of Sphinx.
 
 - A new document from Thorsten on bisection
 
 ...and lots of fixes and updates.

c20eaf4411 cxl/region: Add sysfs attribute for locality attributes of CXL regions 
Add read/write latencies and bandwidth sysfs attributes for the enabled CXL
region. The bandwidth is the aggregated bandwidth of all devices that
contribute to the CXL region. The latency is the worst latency of the
device amongst all the devices that contribute to the CXL region.

8076fcde01 x86/rfds: Mitigate Register File Data Sampling (RFDS) 
RFDS is a CPU vulnerability that may allow userspace to infer kernel
stale data previously used in floating point registers, vector registers
and integer registers. RFDS only affects certain Intel Atom processors.

Intel released a microcode update that uses VERW instruction to clear
the affected CPU buffers. Unlike MDS, none of the affected cores support
SMT.

Add RFDS bug infrastructure and enable the VERW based mitigation by
default, that clears the affected buffers just before exiting to
userspace. Also add sysfs reporting and cmdline parameter
"reg_file_data_sampling" to control the mitigation.

For details see:

b12f3ea7c1 drm/panfrost: Replace fdinfo's profiling debugfs knob with sysfs 
Debugfs isn't always available in production builds that try to squeeze
every single byte out of the kernel image, but we still need a way to
toggle the timestamp and cycle counter registers so that jobs can be
profiled for fdinfo's drm engine and cycle calculations.

Drop the debugfs knob and replace it with a sysfs file that accomplishes
the same functionality, and document its ABI in a separate file.

6025b9135f net: dqs: add NIC stall detector based on BQL 
softnet_data->time_squeeze is sometimes used as a proxy for
host overload or indication of scheduling problems. In practice
this statistic is very noisy and has hard to grasp units -
e.g. is 10 squeezes a second to be expected, or high?

Delaying network (NAPI) processing leads to drops on NIC queues
but also RTT bloat, impacting pacing and CA decisions.
Stalls are a little hard to detect on the Rx side, because
there may simply have not been any packets received in given
period of time. Packet timestamps help a little bit, but
again we don't know if packets are stale because we're
not keeping up or because someone (*cough* cgroups)
disabled IRQs for a long time.

We can, however, use Tx as a proxy for Rx stalls. Most drivers
use combined Rx+Tx NAPIs so if Tx gets starved so will Rx.
On the Tx side we know exactly when packets get queued,
and completed, so there is no uncertainty.

This patch adds stall checks to BQL. Why BQL? Because
it's a convenient place to add such checks, already
called by most drivers, and it has copious free space
in its structures (this patch adds no extra cache
references or dirtying to the fast path).

The algorithm takes one parameter - max delay AKA stall
threshold and increments a counter whenever NAPI got delayed
for at least that amount of time. It also records the length
of the longest stall.

To be precise every time NAPI has not polled for at least
stall thrs we check if there were any Tx packets queued
between last NAPI run and now - stall_thrs/2.

Unlike the classic Tx watchdog this mechanism does not
ignore stalls caused by Tx being disabled, or loss of link.
I don't think the check is worth the complexity, and
stall is a stall, whether due to host overload, flow
control, link down... doesn't matter much to the application.

We have been running this detector in production at Meta
for 2 years, with the threshold of 8ms. It's the lowest
value where false positives become rare. There's still
a constant stream of reported stalls (especially without
the ksoftirqd deferral patches reverted), those who like
their stall metrics to be 0 may prefer higher value.

96d947d4ab Documentation: leds: Update led-trigger-tty ABI description 
The 'led-trigger-tty' uses the same naming in the ABI documentation as

Renaming the 'What' path by prefixing it with 'tty_' solves this problem.

12fc84e8c4 usb: Export BOS descriptor to sysfs 
Motivation
----------

The binary device object store (BOS) of a USB device consists of the BOS
descriptor followed by a set of device capability descriptors. One that is
of interest to users is the platform descriptor. This contains a 128-bit
UUID and arbitrary data, and it allows parties outside of USB-IF to add
additional metadata about a USB device in a standards-compliant manner.
Notable examples include the WebUSB and Microsoft OS 2.0 descriptors.

The kernel already retrieves and caches the BOS from USB devices if its
bcdUSB is >= 0x0201. Because the BOS is flexible and extensible, we export
the entire BOS to sysfs so users can retrieve whatever device capabilities
they desire, without requiring USB I/O or elevated permissions.

Implementation
--------------

Add bos_descriptors attribute to sysfs. This is a binary file and it works
the same way as the existing descriptors attribute. The file exists only if
the BOS is present in the USB device.

Also create a binary attribute group, so the driver core can handle the
creation of both the descriptors and bos_descriptors attributes in sysfs.

3ae768a132 f2fs: doc: Fix bouncing email address for Sahitya Tummala 
The servers for the @codeaurora domain are long retired and any messages
addressed there will bounce.  Sahitya Tummala has a .mailmap entry to an
updated address, but the documentation files still list @codeaurora
which might be a problem for anyone reading the documentation directly.
Update the documentation files to match the .mailmap update.

a8f62f50b4 virtiofs: export filesystem tags through sysfs 
The virtiofs filesystem is mounted using a "tag" which is exported by
the virtiofs device:

  # mount -t virtiofs <tag> /mnt

The virtiofs driver knows about all the available tags but these are
currently not exported to user space.

People have asked for these tags to be exported to user space. Most
recently Lennart Poettering has asked for it as he wants to scan the
tags and mount virtiofs automatically in certain cases.

https://gitlab.com/virtio-fs/virtiofsd/-/issues/128

This patch exports tags at /sys/fs/virtiofs/<N>/tag where N is the id of
the virtiofs device. The filesystem tag can be obtained by reading this
"tag" file.

There is also a symlink at /sys/fs/virtiofs/<N>/device that points to
the virtiofs device that exports this tag.

This patch converts the existing struct virtio_fs into a full kobject.
It already had a refcount so it's an easy change. The virtio_fs objects
can then be exposed in a kset at /sys/fs/virtiofs/. Note that virtio_fs
objects may live slightly longer than we wish for them to be exposed to
userspace, so kobject_del() is called explicitly when the underlying
virtio_device is removed. The virtio_fs object is freed when all
references are dropped (e.g. active mounts) but disappears as soon as
the virtiofs device is gone.

b9ad003af1 mm/cma: add sysfs file 'release_pages_success' 
This adds the following new sysfs file tracking the number of successfully
released pages from a given CMA heap area.  This file will be available
via CONFIG_CMA_SYSFS and help in determining active CMA pages available on
the CMA heap area.  This adds a new 'nr_pages_released' (CONFIG_CMA_SYSFS)
into 'struct cma' which gets updated during cma_release().

/sys/kernel/mm/cma/<cma-heap-area>/release_pages_success

After this change, an user will be able to find active CMA pages available
in a given CMA heap area via the following method.

Active pages = alloc_pages_success - release_pages_success

That's valuable information for both software designers, and system admins
as it allows them to tune the number of CMA pages available in the system.
This increases user visibility for allocated CMA area and its
utilization.

dce41f5ae2 mm/mempolicy: implement the sysfs-based weighted_interleave interface 
Patch series "mm/mempolicy: weighted interleave mempolicy and sysfs
extension", v5.

Weighted interleave is a new interleave policy intended to make use of
heterogeneous memory environments appearing with CXL.

The existing interleave mechanism does an even round-robin distribution of
memory across all nodes in a nodemask, while weighted interleave
distributes memory across nodes according to a provided weight.  (Weight =
# of page allocations per round)

Weighted interleave is intended to reduce average latency when bandwidth
is pressured - therefore increasing total throughput.

In other words: It allows greater use of the total available bandwidth in
a heterogeneous hardware environment (different hardware provides
different bandwidth capacity).

As bandwidth is pressured, latency increases - first linearly and then
exponentially.  By keeping bandwidth usage distributed according to
available bandwidth, we therefore can reduce the average latency of a
cacheline fetch.

A good explanation of the bandwidth vs latency response curve:
https://mahmoudhatem.wordpress.com/2017/11/07/memory-bandwidth-vs-latency-response-curve/

From the article:
```
Constant region:
    The latency response is fairly constant for the first 40%
    of the sustained bandwidth.
Linear region:
    In between 40% to 80% of the sustained bandwidth, the
    latency response increases almost linearly with the bandwidth
    demand of the system due to contention overhead by numerous
    memory requests.
Exponential region:
    Between 80% to 100% of the sustained bandwidth, the memory
    latency is dominated by the contention latency which can be
    as much as twice the idle latency or more.
Maximum sustained bandwidth :
    Is 65% to 75% of the theoretical maximum bandwidth.
```

As a general rule of thumb:
* If bandwidth usage is low, latency does not increase. It is
  optimal to place data in the nearest (lowest latency) device.
* If bandwidth usage is high, latency increases. It is optimal
  to place data such that bandwidth use is optimized per-device.

This is the top line goal: Provide a user a mechanism to target using the
"maximum sustained bandwidth" of each hardware component in a heterogenous
memory system.


For example, the stream benchmark demonstrates that 1:1 (default)
interleave is actively harmful, while weighted interleave can be
beneficial.  Default interleave distributes data such that too much
pressure is placed on devices with lower available bandwidth.

Stream Benchmark (vs DRAM, 1 Socket + 1 CXL Device)
Default interleave : -78% (slower than DRAM)
Global weighting   : -6% to +4% (workload dependant)
Targeted weights   : +2.5% to +4% (consistently better than DRAM)

Global means the task-policy was set (set_mempolicy), while targeted means
VMA policies were set (mbind2).  We see weighted interleave is not always
beneficial when applied globally, but is always beneficial when applied to
bandwidth-driving memory regions.


There are 4 patches in this set:
1) Implement system-global interleave weights as sysfs extension
   in mm/mempolicy.c.  These weights are RCU protected, and a
   default weight set is provided (all weights are 1 by default).

   In future work, we intend to expose an interface for HMAT/CDAT
   code to set reasonable default values based on the memory
   configuration of the system discovered at boot/hotplug.

2) A mild refactor of some interleave-logic for re-use in the
   new weighted interleave logic.

3) MPOL_WEIGHTED_INTERLEAVE extension for set_mempolicy/mbind

4) Protect interleave logic (weighted and normal) with the
   mems_allowed seq cookie.  If the nodemask changes while
   accessing it during a rebind, just retry the access.

Included below are some performance and LTP test information,
and a sample numactl branch which can be used for testing.

(tests may have different configurations, see extended info below)

This patch (of 4):

This patch provides a way to set interleave weight information under sysfs
at /sys/kernel/mm/mempolicy/weighted_interleave/nodeN

The sysfs structure is designed as follows.

  $ tree /sys/kernel/mm/mempolicy/
  /sys/kernel/mm/mempolicy/ [1]
  └── weighted_interleave [2]
      ├── node0 [3]
      └── node1

Each file above can be explained as follows.

[1] mm/mempolicy: configuration interface for mempolicy subsystem

[2] weighted_interleave/: config interface for weighted interleave policy

[3] weighted_interleave/nodeN: weight for nodeN

If a node value is set to `0`, the system-default value will be used.
As of this patch, the system-default for all nodes is always 1.

73954d379e dax: add a sysfs knob to control memmap_on_memory behavior 
Add a sysfs knob for dax devices to control the memmap_on_memory setting
if the dax device were to be hotplugged as system memory.

The default memmap_on_memory setting for dax devices originating via pmem
or hmem is set to 'false' - i.e.  no memmap_on_memory semantics, to
preserve legacy behavior.  For dax devices via CXL, the default is on. 
The sysfs control allows the administrator to override the above defaults
if needed.

ASoC: Intel: avs: Fixes and new platforms support 
Merge series from Cezary Rojewski <cezary.rojewski@intel.com>:

The avs-driver continues to be utilized on more recent Intel machines.
As TGL-based (cAVS 2.5) e.g.: RPL, inherit most of the functionality
from previous platforms:

SKL <- APL <- CNL <- ICL <- TGL

rather than putting everything into a single file, the platform-specific
bits are split into cnl/icl/tgl.c files instead. Makes the division clear
and code easier to maintain.

Layout of the patchset:

First are two changes combined together address the sound-clipping
problem, present when only one stream is running - specifically one
CAPTURE stream.

Follow up is naming-scheme adjustment for some of the existing functions
what improves code incohesiveness. As existing IPC/IRQ code operates
solely on cAVS 1.5 architecture, it needs no abstraction. The situation
changes when newer platforms come into the picture. Thus the next two
patches abstract the existing IPC/IRQ handlers so that majority of the
common code can be re-used.

The ICCMAX change stands out a bit - the AudioDSP firmware loading
procedure differs on ICL-based platforms (and onwards) and having a
separate commit makes the situation clear to the developers who are
going to support the solution from LTS perspective. For that reason
I decided not to merge it into the commit introducing the icl.c file.

The pattern match trigger output is achieved via setting values into

After configuring a pattern through these registers, the TPDM subunit
will assert an output trigger every time it receives new input data
that matches the configured pattern value. Values in a given bit
number of the mask register correspond to the same bit number in

After we inject fault into f2fs_is_valid_blkaddr() during truncation,
a) it missed to increase @nr_free or @valid_blocks
b) it can cause in blkaddr leak in truncated dnode
Which may cause inconsistent status.

This patch separates FAULT_BLKADDR_CONSISTENCE from FAULT_BLKADDR,
and rename FAULT_BLKADDR to FAULT_BLKADDR_VALIDITY
so that we can:
a) use FAULT_BLKADDR_CONSISTENCE in f2fs_truncate_data_blocks_range()
to simulate inconsistent issue independently, then it can verify fsck
repair flow.
b) FAULT_BLKADDR_VALIDITY fault will not cause any inconsistent status,
we can just use it to check error path handling in kernel side.

43a029724d usb: gadget: f_fs: expose ready state in configfs 
When a USB gadget is configured through configfs with 1 or more f_fs
functions, then the logic setting up the gadget configuration has to wait
until the user space code (typically separate applications) responsible for
those functions have written their descriptors before the gadget can be
activated.

The f_fs instance already knows if this has been done, so expose it through
a "ready" attribute in configfs for easier synchronization.

Merge tag 'cxl-for-6.8' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl

Pull CXL (Compute Express Link) updates from Dan Williams:
 "The bulk of this update is support for enumerating the performance
  capabilities of CXL memory targets and connecting that to a platform
  CXL memory QoS class. Some follow-on work remains to hook up this data
  into core-mm policy, but that is saved for v6.9.

  The next significant update is unifying how CXL event records (things
  like background scrub errors) are processed between so called
  "firmware first" and native error record retrieval. The CXL driver
  handler that processes the record retrieved from the device mailbox is
  now the handler for that same record format coming from an EFI/ACPI
  notification source.

  This also contains miscellaneous feature updates, like Get Timestamp,
  and other fixups.

  Summary:

   - Add support for parsing the Coherent Device Attribute Table (CDAT)

   - Add support for calculating a platform CXL QoS class from CDAT data

   - Unify the tracing of EFI CXL Events with native CXL Events.

   - Add Get Timestamp support

   - Miscellaneous cleanups and fixups"

Pull VFIO updates from Alex Williamson:

 - Add debugfs support, initially used for reporting device migration
   state (Longfang Liu)

 - Fixes and support for migration dirty tracking across multiple IOVA
   regions in the pds-vfio-pci driver (Brett Creeley)

 - Improved IOMMU allocation accounting visibility (Pasha Tatashin)

 - Virtio infrastructure and a new virtio-vfio-pci variant driver, which
   provides emulation of a legacy virtio interfaces on modern virtio
   hardware for virtio-net VF devices where the PF driver exposes
   support for legacy admin queues, ie. an emulated IO BAR on an SR-IOV
   VF to provide driver ABI compatibility to legacy devices (Yishai
   Hadas & Feng Liu)

80955ae955 Driver core changes for 6.8-rc1 
Here are the set of driver core and kernfs changes for 6.8-rc1.  Nothing
 major in here this release cycle, just lots of small cleanups and some
 tweaks on kernfs that in the very end, got reverted and will come back
 in a safer way next release cycle.
 
 Included in here are:
   - more driver core 'const' cleanups and fixes
   - fw_devlink=rpm is now the default behavior
   - kernfs tiny changes to remove some string functions
   - cpu handling in the driver core is updated to work better on many
     systems that add topologies and cpus after booting
   - other minor changes and cleanups
 
 All of the cpu handling patches have been acked by the respective
 maintainers and are coming in here in one series.  Everything has been
 in linux-next for a while with no reported issues.

Merge tag 'drm-next-2024-01-10' of git://anongit.freedesktop.org/drm/drm

Pull drm updates from Dave Airlie:
 "This contains two major new drivers:

   - imagination is a first driver for Imagination Technologies devices,
     it only covers very specific devices, but there is hope to grow it

   - xe is a reboot of the i915 GPU (shares display) side using a more
     upstream focused development model, and trying to maximise code
     sharing. It's not enabled for any hw by default, and will hopefully
     get switched on for Intel's Lunarlake.

  This also drops a bunch of the old UMS ioctls. It's been dead long
  enough.

  amdgpu has a bunch of new color management code that is being used in
  the Steam Deck.

  amdgpu also has a new ACPI WBRF interaction to help avoid radio
  interference.

70d201a408 f2fs update for 6.8-rc1 
In this series, we've some progress to support Zoned block device regarding to
 the power-cut recovery flow and enabling checkpoint=disable feature which is
 essential for Android OTA. Other than that, some patches touched sysfs entries
 and tracepoints which are minor, while several bug fixes on error handlers and
 compression flows are good to improve the overall stability.
 
 Enhancement:
  - enable checkpoint=disable for zoned block device
  - sysfs entries such as discard status, discard_io_aware, dir_level
  - tracepoints such as f2fs_vm_page_mkwrite(), f2fs_rename(), f2fs_new_inode()
  - use shared inode lock during f2fs_fiemap() and f2fs_seek_block()
 
 Bug fix:
  - address some power-cut recovery issues on zoned block device
  - handle errors and logics on do_garbage_collect(), f2fs_reserve_new_block(),
    f2fs_move_file_range(), f2fs_recover_xattr_data()
  - don't set FI_PREALLOCATED_ALL for partial write
  - fix to update iostat correctly in f2fs_filemap_fault()
  - fix to wait on block writeback for post_read case
  - fix to tag gcing flag on page during block migration
  - restrict max filesize for 16K f2fs
  - fix to avoid dirent corruption
  - explicitly null-terminate the xattr list
 
 There are also several clean-up patches to remove dead codes and better
 readability.

f6597d1706 SoC: driver updates for 6.8 
A new drivers/cache/ subsystem is added to contain drivers for abstracting
 cache flush methods on riscv and potentially others, as this is needed for
 handling non-coherent DMA but several SoCs require nonstandard hardware
 methods for it.
 
 op-tee gains support for asynchronous notification with FF-A, as well
 as support for a system thread for executing in secure world.
 
 The tee, reset, bus, memory and scmi subsystems have a couple of minor
 updates.
 
 Platform specific soc driver changes include:
 
  - Samsung Exynos gains driver support for Google GS101 (Tensor G1)
    across multiple subsystems
 
  - Qualcomm Snapdragon gains support for SM8650 and X1E along with
    added features for some other SoCs
 
  - Mediatek adds support for "Smart Voltage Scaling" on MT8186 and MT8195,
    and driver support for MT8188 along with some code refactoring.
 
  - Microchip Polarfire FPGA support for "Auto Update" of the FPGA bitstream
 
  - Apple M1 mailbox driver is rewritten into a SoC driver
 
  - minor updates on amlogic, mvebu, ti, zynq, imx, renesas and hisilicon

Merge tag 'pm-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management updates from Rafael Wysocki:
 "These add support for new processors (Sierra Forest, Grand Ridge and
  Meteor Lake) to the intel_idle driver, make intel_pstate run on
  Emerald Rapids without HWP support and adjust it to utilize EPP values
  supplied by the platform firmware, fix issues, clean up code and
  improve documentation.

  The most significant fix addresses deadlocks in the core system-wide
  resume code that occur if async_schedule_dev() attempts to run its
  argument function synchronously (for example, due to a memory
  allocation failure). It rearranges the code in question which may
  increase the system resume time in some cases, but this basically is a
  removal of a premature optimization. That optimization will be added
  back later, but properly this time.

  Specifics:

   - Add support for the Sierra Forest, Grand Ridge and Meteorlake SoCs
     to the intel_idle cpuidle driver (Artem Bityutskiy, Zhang Rui)

   - Do not enable interrupts when entering idle in the haltpoll cpuidle
     driver (Borislav Petkov)

Expose through debugfs ring pair telemetry data for QAT GEN4 devices.

This allows to gather metrics about the PCIe channel and device TLB for
a selected ring pair. It is possible to monitor maximum 4 ring pairs at
the time per device.

For details, refer to debugfs-driver-qat_telemetry in Documentation/ABI.

69e7649f7c crypto: qat - add support for device telemetry 
Expose through debugfs device telemetry data for QAT GEN4 devices.

This allows to gather metrics about the performance and the utilization
of a device. In particular, statistics on (1) the utilization of the
PCIe channel, (2) address translation, when SVA is enabled and (3) the
internal engines for crypto and data compression.

If telemetry is supported by the firmware, the driver allocates a DMA
region and a circular buffer. When telemetry is enabled, through the
`control` attribute in debugfs, the driver sends to the firmware, via
the admin interface, the `TL_START` command. This triggers the device to
periodically gather telemetry data from hardware registers and write it
into the DMA memory region. The device writes into the shared region
every second.

The driver, every 500ms, snapshots the DMA shared region into the
circular buffer. This is then used to compute basic metric
(min/max/average) on each counter, every time the `device_data` attribute
is queried.

Telemetry counters are exposed through debugfs in the folder
/sys/kernel/debug/qat_<device>_<BDF>/telemetry.

For details, refer to debugfs-driver-qat_telemetry in Documentation/ABI.

This patch is based on earlier work done by Wojciech Ziemba.

42834b17cf cxl: Export sysfs attributes for memory device QoS class 
Export qos_class sysfs attributes for the CXL memory device. The QoS clas
should show up as /sys/bus/cxl/devices/memX/ram/qos_class for the volatile
partition and /sys/bus/cxl/devices/memX/pmem/qos_class for the persistent
partition. The QTG ID is retrieved via _DSM after supplying the
calculated bandwidth and latency for the entire CXL path from device to
the CPU. This ID is used to match up to the root decoder QoS class to
determine which CFMWS the memory range of a hotplugged CXL mem device
should be assigned under.

While there may be multiple DSMAS exported by the device CDAT, the driver
will only expose the first QTG ID per partition in sysfs for now. In the

Greg Kroah-Hartman
7050abeb8f 1st set of IIO new device support, features and cleanup for 6.8 
New device support
 ------------------
 
 adi,hmc425a
   * Add support for ADRF5740 attenuators.  Minor changes to driver needed
     alongside new IDs.
 aosong,ags02ma
   * New driver for this volatile organic compounds sensor.
 bosch,bmp280
   * Add BMP390 (small amount of refactoring + ID)
 bosch,bmi323
   * New driver to support the BMI323 6-axis IMU.
 honeywell,hsc030pa
   * New driver supporting a huge number of SSC and HSC series pressure and
     temperature sensors.
 isil,isl76682
   * New driver for this simple Ambient Light sensor.
 liteon,ltr390
   * New driver for this ambient and ultraviolet light sensor.
 maxim,max34408
   * New driver to support the MAX34408 and MAX34409 current monitoring ADCs.
 melexis,mlx90635
   * New driver for this Infrared contactless temperature sensor.
 mirochip,mcp9600
   * New driver for this thermocouple EMF convertor.
 ti,hdc3020
   * New driver for this integrated relative humidity and temperature
     sensor.
 vishay,veml6075
   * New driver for this UVA and UVB light sensor.
 
 General features
 ----------------
 
 Device properties
   * Add fwnode_property_match_property_string() helper to allow matching
     single value property against an array of predefined strings.
   * Use fwnode_property_string_array_count() inside
     fwnode_property_match_string() instead of open coding the same.
 checkpatch.pl
   * Add exclusion of __aligned() from a warning reducing false positives
     on IIO drivers (and hopefully beyond)
 
 IIO Features
 ------------
 
 core
   * New light channel modifiers for UVA and UVB.
   * Add IIO_CHAN_INFO_TROUGH as counterpart to IIO_CHAN_INFO_PEAK so that
     we can support device that keep running track of the lowest value they
     have seen in similar fashion to the existing peak tracking.
 adi,adis library
   * Use spi cs inactive delay even when a burst reading is performed.
     As it's now used every time, can centralize the handling in the SPI
     setup code in the driver.
 adi,ad2s1210
   * Support for fixed-mode to this resolver driver where the A0 and A1
     pins are hard wired to config mode in which case position and config
     must be read from appropriate config registers.
   * Support reset GPIO if present.
 adi,ad5791
   * Allow configuration of presence of external amplifier in DT binding.
 adi,adis16400
   * Add spi-cs-inactive-delay-ns to bindings to allow it to be tweaked
     if default delays are not quite enough for a specific board.
 adi,adis16475
   * Add spi-cs-inactive-delay-ns to bindings to allow it to be tweaked
     if default delays are not quite enough for a specific board.
 bosch,bmp280
   * Enable multiple chip IDs per family of devices.
 rohm,bu27008
   * Add an illuminance channel calculated from RGB and IR data.
 
 Cleanup
 -------
 
 Minor white space, typos and tidy up not explicitly called out.
 
 Core
   * Check that the available_scan_masks array passed to the IIO core
     by a driver is sensible by ensuring the entries are ordered so the
     minimum number of channels is enabled in the earlier entries (as they
     will be selected if sufficient for the requested channels).
   * Document that the available_scan_masks infrastructure doesn't currently
     handle masks that don't fit in a long int.
   * Improve intensity documentation to reflect that there is no expectation
     of sensible units (it's dependent on a frequency sensitivity curve)
 Various
   * Use new device_property_match_property_string() to replace open coded
     versions of the same thing.
   * Fix a few MAINTAINERS filenames.
   * i2c_get_match_data() and spi_get_device_match_data() pushed into
     more drivers reducing boilerplate handling.
   * Some unnecessary headers removed.
   * ACPI_PTR() removals. It's rarely worth using this.
 adi,ad7091r (early part of a series adding device support - useful in
   their own right)
   * Pass iio_dev directly an event handler rather than relying
     on broken use of dev_get_drvdata() as drvdata is never set in this driver.
   * Make sure alert is turned on.
 adi,ad9467 (general driver fixing up as precursor to iio-backend proposal
   which is under review for 6.9)
   * Fix reset gpio handling to match expected polarity.
   * Always handle error codes from spi_writes.
   * Add a driver instance local mutex to avoid some races.
   * Fix scale setting to align with available scale values.
   * Split array of chip_info structures up into named individual elements.
   * Convert to regmap.
 honeywell,mprls0025pa
   * Drop now unnecessary type references in DT binding for properties in
     pascals.
 invensense,mpu6050
   * Don't eat a potentially useful return value from regmap_bulk_write()
 invensense,icm42600
   * Use max macro to improve code readability and save a few lines.
 liteon,ltrf216a
   * Improve prevision of light intensity.
 microchip,mcp3911
   * Use cleanup.h magic.
 qcom,spmi*
   * Fix wrong descriptions of SPMI reg fields in bindings.
 
 Other
 ----

   * Update for Matt Ranostay

honeywell,hsc030pa
  * New driver supporting a huge number of SSC and HSC series pressure and
    temperature sensors.
isil,isl76682
  * New driver for this simple Ambient Light sensor.
liteon,ltr390
  * New driver for this ambient and ultraviolet light sensor.

ti,hdc3020
  * New driver for this integrated relative humidity and temperature
    sensor.
vishay,veml6075
  * New driver for this UVA and UVB light sensor.

General features
----------------

Device properties
  * Add fwnode_property_match_property_string() helper to allow matching
    single value property against an array of predefined strings.
  * Use fwnode_property_string_array_count() inside
    fwnode_property_match_string() instead of open coding the same.
checkpatch.pl
  * Add exclusion of __aligned() from a warning reducing false positives
    on IIO drivers (and hopefully beyond)

IIO Features
------------

core
  * New light channel modifiers for UVA and UVB.
  * Add IIO_CHAN_INFO_TROUGH as counterpart to IIO_CHAN_INFO_PEAK so that
    we can support device that keep running track of the lowest value they
    have seen in similar fashion to the existing peak tracking.
adi,adis library
  * Use spi cs inactive delay even when a burst reading is performed.
    As it's now used every time, can centralize the handling in the SPI
    setup code in the driver.
adi,ad2s1210
  * Support for fixed-mode to this resolver driver where the A0 and A1
    pins are hard wired to config mode in which case position and config
    must be read from appropriate config registers.
  * Support reset GPIO if present.
adi,ad5791
  * Allow configuration of presence of external amplifier in DT binding.
adi,adis16400
  * Add spi-cs-inactive-delay-ns to bindings to allow it to be tweaked
    if default delays are not quite enough for a specific board.
adi,adis16475
  * Add spi-cs-inactive-delay-ns to bindings to allow it to be tweaked
    if default delays are not quite enough for a specific board.
bosch,bmp280
  * Enable multiple chip IDs per family of devices.
rohm,bu27008
  * Add an illuminance channel calculated from RGB and IR data.

Cleanup
-------

Minor white space, typos and tidy up not explicitly called out.

Core
  * Check that the available_scan_masks array passed to the IIO core
    by a driver is sensible by ensuring the entries are ordered so the
    minimum number of channels is enabled in the earlier entries (as they
    will be selected if sufficient for the requested channels).
  * Document that the available_scan_masks infrastructure doesn't currently
    handle masks that don't fit in a long int.
  * Improve intensity documentation to reflect that there is no expectation
    of sensible units (it's dependent on a frequency sensitivity curve)
Various
  * Use new device_property_match_property_string() to replace open coded
    versions of the same thing.
  * Fix a few MAINTAINERS filenames.
  * i2c_get_match_data() and spi_get_device_match_data() pushed into
    more drivers reducing boilerplate handling.
  * Some unnecessary headers removed.
  * ACPI_PTR() removals. It's rarely worth using this.
adi,ad7091r (early part of a series adding device support - useful in
  their own right)
  * Pass iio_dev directly an event handler rather than relying
    on broken use of dev_get_drvdata() as drvdata is never set in this driver.
  * Make sure alert is turned on.
adi,ad9467 (general driver fixing up as precursor to iio-backend proposal
  which is under review for 6.9)
  * Fix reset gpio handling to match expected polarity.
  * Always handle error codes from spi_writes.
  * Add a driver instance local mutex to avoid some races.
  * Fix scale setting to align with available scale values.
  * Split array of chip_info structures up into named individual elements.
  * Convert to regmap.
honeywell,mprls0025pa
  * Drop now unnecessary type references in DT binding for properties in
    pascals.
invensense,mpu6050
  * Don't eat a potentially useful return value from regmap_bulk_write()
invensense,icm42600
  * Use max macro to improve code readability and save a few lines.
liteon,ltrf216a
  * Improve prevision of light intensity.
microchip,mcp3911
  * Use cleanup.h magic.
qcom,spmi*
  * Fix wrong descriptions of SPMI reg fields in bindings.

aa5cea38ce accel/habanalabs: add parent_device sysfs attribute 
The device debugfs directory was modified to be named as the
device-name.
This name is the parent device name, i.e. either the PCI address in case
of an ASIC, or the simulator device name in case of a simulator.

This change makes it more difficult for a user to access the debugfs
directory for a specific accel device, because he can't just use the
accel minor id, but he needs to do more device-dependent operations to
get the device name.

To make it easier to get this name, add a 'parent_device' sysfs
attribute that the user can read using the minor id before accessing
debugfs.

Module ID exposes the physical location of the device in the server,
from the pov of the devices in regard to how they are connected by
internal fabric.

This information is already exposed in our INFO ioctl, but there are
utilities and scripts running in data-center which are already
accessing sysfs for topology information and it is easier for them
to continue getting that information from sysfs instead of opening
a file descriptor.

2678fd2fe9 initramfs: Expose retained initrd as sysfs file 
When the kernel command line option "retain_initrd" is set, we do not
free the initrd memory. However, we also don't expose it to anyone for
consumption. That leaves us in a weird situation where the only user of
this feature is ppc64 and arm64 specific kexec tooling.

To make it more generally useful, this patch adds a kobject to the
firmware object that contains the initrd context when "retain_initrd"
is set. That way, we can access the initrd any time after boot from
user space and for example hand it into kexec as --initrd parameter
if we want to reboot the same initrd. Or inspect it directly locally.

With this patch applied, there is a new /sys/firmware/initrd file when
the kernel was booted with an initrd and "retain_initrd" command line
option is set.

192048e5a5 ABI: sysfs-nvmem-cells: Expose cells through sysfs 
The binary content of nvmem devices is available to the user so in the
easiest cases, finding the content of a cell is rather easy as it is
just a matter of looking at a known and fixed offset. However, nvmem
layouts have been recently introduced to cope with more advanced
situations, where the offset and size of the cells is not known in
advance or is dynamic. When using layouts, more advanced parsers are
used by the kernel in order to give direct access to the content of each
cell regardless of their position/size in the underlying device, but
these information were not accessible to the user.

By exposing the nvmem cells to the user through a dedicated cell/ folder
containing one file per cell, we provide a straightforward access to
useful user information without the need for re-writing a userland
parser. Content of nvmem cells is usually: product names, manufacturing
date, MAC addresses, etc,

6df14a32e9 Merge patch series "Add UFS RTC support" 
Bean Huo <beanhuo@iokpp.de> says:

Adding RTC support for embedded storage device UFS in its driver, it
is important for a few key reasons:

1. Helps with Regular Maintenance:
The RTC provides a basic way to keep track of time, making it useful for
scheduling routine maintenance tasks in the storage device. This includes
things like making sure data is spread
evenly across the storage to extend its life.

2. Figuring Out How Old Data Is:
The RTC helps the device estimate how long ago certain parts of the storage
were last used. This is handy for deciding when to do maintenance tasks to
keep the storage working well over time.

3. Making Devices Last Longer:
By using the RTC for regular upkeep, we can make sure the storage device lasts
longer and stays reliable. This is especially important for devices that need
to work well for a long time.

4.Fitting In with Other Devices:
The inclusion of RTC support aligns with existing UFS specifications (starting
from UFS Spec 2.0) and is consistent with the prevalent industry practice. Many
UFS devices currently on the market utilize RTC for internal timekeeping. By
ensuring compatibility with this widely adopted standard, the embedded storage
device becomes seamlessly integrable with existing hardware and software
ecosystems, reducing the risk of compatibility issues.

In short, adding RTC support to embedded storage device UFS helps with regular
upkeep, extends the device's life, ensures compatibility, and keeps everything
running smoothly with the rest of the system.

6dec659896 leds: ledtrig-tty: Add additional line state evaluation 
The serial tty interface also supports additional input signals, that
can also be evaluated within this trigger. This change is adding the
following additional input sources, which could be controlled
via the '/sys/class/<leds>/' sysfs interface.

Explanation:
DCE = Data Communication Equipment (Modem)
DTE = Data Terminal Equipment (Computer)

- cts:
  DCE is ready to accept data from the DTE (CTS = Clear To Send). If
  the line state is detected, the LED is switched on.
  If set to 0 (default), the LED will not evaluate CTS.
  If set to 1, the LED will evaluate CTS.

- dsr:
  DCE is ready to receive and send data (DSR = Data Set Ready). If the
  line state is detected, the LED is switched on.
  If set to 0 (default), the LED will not evaluate DSR.
  If set to 1, the LED will evaluate DSR.

- dcd:
  DTE is receiving a carrier from the DCE (DCD = Data Carrier Detect).
  If the line state is detected, the LED is switched on.
  If set to 0 (default), the LED will not evaluate DCD.
  If set to 1, the LED will evaluate DCD.

- rng:
  DCE has detected an incoming ring signal on the telephone line
  (RNG = Ring Indicator). If the line state is detected, the LED is
  switched on.
  If set to 0 (default), the LED will not evaluate RNG.
  If set to 1, the LED will evaluate RNG.

Also add an invert flag on LED blink, so that the LED blinks in the
correct order.

* If one off the new enabled input signals are evaluatet as 'enabled',
  and data are transmitted, then the LED should first blink 'off' and
  then 'on' (invert).
* If all the new enabled input signals are evaluatet as 'disabled',
  and data are transmitted, then the LED should first blink 'on' and
  then 'off'.

5b755ca677 leds: ledtrig-tty: Make rx tx activitate configurable 
Until now, the LED blinks when data is sent via the tty (rx/tx).
This is not configurable.

This change adds the possibility to make the indication for the direction
of the transmitted data independently controllable via the new rx and
tx sysfs entries.

- rx:
  Signal reception (rx) of data on the named tty device.
  If set to 0, the LED will not blink on reception.
  If set to 1 (default), the LED will blink on reception.

- tx:
  Signal transmission (tx) of data on the named tty device.
  If set to 0, the LED will not blink on transmission.
  If set to 1 (default), the LED will blink on transmission.

This new sysfs entry are on by default. Thus the trigger behaves as
before this change.

2de83b67cf ABI: sysfs-class-hwmon: fix tempY_crit_alarm access rights 
This attribute is defined as read-only by all drivers that support it.

It seems that the access rights and description for this attribute were
copied from the intrusionY_alarm, which has indeed RW rights and must be
cleared by the user.

These are the modules that currently use this attribute:
- adt7x10
- i5500_temp
- jc42
- lm83
- lm90
- lm95245
- max31760
- max6621
- mc34vr500
- tmp401
- tmp464

Fix the attribute description and make it read-only.

Adding new elements alphabetically is a common practice that has been
loosely followed in the sysfs-class-hwmon documentation. Since most of
the humidity attributes must be added to the file, a single attribute
needs to be rearranged to reinforce alphabetical order.

a6adef8987 ARM: SoC fixes for v6.7 
Most of the changes are devicetree fixes for NXP, Mediatek, Rockchips
 Arm machines as well as Microchip RISC-V, and most of these address
 build-time warnings for spec violations and other minor issues. One of
 the Mediatek warnings was enabled by default and prevented a clean build.
 The ones that address serious runtime issues are all on the i.MX platform:
 
  - a boot time panic on imx8qm
  - USB hanging under load on imx8
  - regressions on the imx93 ethernet phy
 
 Code fixes include a minor error handling for the i.MX PMU driver, and
 a number of firmware driver fixes:
 
  - OP-TEE fix for supplicant based device enumeration, and a new
    sysfs attribute to needed to fix a race against userspace
 
  - Arm SCMI fix for possible truncation/overflow in the frequency
    computations
 
  - Multiple FF-A fixes for the newly added notification support.

b89710bd21 iio: add modifiers for A and B ultraviolet light 
Currently there are only two modifiers for ultraviolet light: a generic
one for any ultraviolet light (IIO_MOD_LIGHT_UV) and one for deep
ultraviolet (IIO_MOD_LIGHT_DUV), which is also referred as ultraviolet
C (UV-C) band and covers short-wave ultraviolet.

There are still no modifiers for the long-wave and medium-wave
ultraviolet bands. These two bands are the main components used to
obtain the UV index on the Earth's surface.

Add modifiers for the ultraviolet A (UV-A) and ultraviolet B (UV-B)

8f2244c9af leds: class: Don't expose color sysfs entry 
The commit c7d80059b0 ("leds: class: Store the color index in struct
led_classdev") introduced a new sysfs entry "color" that is commonly
created for the led classdev.  Unfortunately, this conflicts with the
"color" sysfs entry of already existing drivers such as Logitech HID
or System76 ACPI drivers.  The driver probe fails due to the conflict,
hence it leads to a severe regression with the missing keyboard, for
example.

This patch reverts partially the change in the commit above for
removing the led class color sysfs entries again for addressing the
regressions.  The newly introduced led_classdev.color field is kept as
it's already used by other driver.

2373699a35 coresight: tmc: Make etr buffer mode user configurable from sysfs 
Currently TMC-ETR automatically selects the buffer mode from all available
methods in the following sequentially fallback manner - also in that order.

1. FLAT mode with or without IOMMU
2. TMC-ETR-SG (scatter gather) mode when available
3. CATU mode when available

But this order might not be ideal for all situations. For example if there
is a CATU connected to ETR, it may be better to use TMC-ETR scatter gather
method, rather than CATU. But hard coding such order changes will prevent
us from testing or using a particular mode. This change provides following
new sysfs tunables for the user to control TMC-ETR buffer mode explicitly,
if required. This adds following new sysfs files for buffer mode selection
purpose explicitly in the user space.

/sys/bus/coresight/devices/tmc_etr<N>/buf_modes_available
/sys/bus/coresight/devices/tmc_etr<N>/buf_mode_preferred

$ cat buf_modes_available
auto flat tmc-sg catu	------------------> Supported TMC-ETR buffer modes

$ echo catu > buf_mode_preferred   -------> Explicit buffer mode request

But explicit user request has to be within supported ETR buffer modes only.
These sysfs interface files are exclussive to ETR, and hence these are not
available for other TMC devices such as ETB or ETF etc.

A new auto' mode (i.e ETR_MODE_AUTO) has been added to help fallback to the
existing default behaviour, when user provided preferred buffer mode fails.
ETR_MODE_FLAT and ETR_MODE_AUTO are always available as preferred modes.

Pull CXL (Compute Express Link) updates from Dan Williams:
 "The main new functionality this time is work to allow Linux to
  natively handle CXL link protocol errors signalled via PCIe AER for
  current generation CXL platforms. This required some enlightenment of
  the PCIe AER core to workaround the fact that current generation RCH
  (Restricted CXL Host) platforms physically hide topology details and
  registers via a mechanism called RCRB (Root Complex Register Block).

  The next major highlight is reworks to address bugs in parsing region
  configurations for next generation VH (Virtual Host) topologies. The
  old broken algorithm is replaced with a simpler one that significantly
  increases the number of region configurations supported by Linux. This
  is again relevant for error handling so that forward and reverse
  address translation of memory errors can be carried out by Linux for
  memory regions instantiated by platform firmware.

  As for other cross-tree work, the ACPI table parsing code has been
  refactored for reuse parsing the "CDAT" structure which is an
  ACPI-like data structure that is reported by CXL devices. That work is
  in preparation for v6.8 support for CXL QoS. Think of this as dynamic
  generation of NUMA node topology information generated by Linux rather
  than platform firmware.

  Lastly, a number of internal object lifetime issues have been resolved
  along with misc. fixes and feature updates (decoders_committed sysfs
  ABI).

  Summary:

   - Add support for RCH (Restricted CXL Host) Error recovery

   - Fix several region assembly bugs

   - Fix mem-device lifetime issues relative to the sanitize command and
     RCH topology.

   - Refactor ACPI table parsing for CDAT parsing re-use in preparation

Pull unified attestation reporting from Dan Williams:
 "In an ideal world there would be a cross-vendor standard attestation
  report format for confidential guests along with a common device
  definition to act as the transport.

  In the real world the situation ended up with multiple platform
  vendors inventing their own attestation report formats with the
  SEV-SNP implementation being a first mover to define a custom
  sev-guest character device and corresponding ioctl(). Later, this
  configfs-tsm proposal intercepted an attempt to add a tdx-guest
  character device and a corresponding new ioctl(). It also anticipated
  ARM and RISC-V showing up with more chardevs and more ioctls().

  The proposal takes for granted that Linux tolerates the vendor report
  format differentiation until a standard arrives. From talking with
  folks involved, it sounds like that standardization work is unlikely
  to resolve anytime soon. It also takes the position that kernfs ABIs
  are easier to maintain than ioctl(). The result is a shared configfs
  mechanism to return per-vendor report-blobs with the option to later
  support a standard when that arrives.

  Part of the goal here also is to get the community into the
  "uncomfortable, but beneficial to the long term maintainability of the
  kernel" state of talking to each other about their differentiation and
  opportunities to collaborate. Think of this like the device-driver
  equivalent of the common memory-management infrastructure for
  confidential-computing being built up in KVM.

  As for establishing an "upstream path for cross-vendor
  confidential-computing device driver infrastructure" this is something
  I want to discuss at Plumbers. At present, the multiple vendor
  proposals for assigning devices to confidential computing VMs likely
  needs a new dedicated repository and maintainer team, but that is a
  discussion for v6.8.

  For now, Greg and Thomas have acked this approach and this is passing
  is AMD, Intel, and Google tests.

  Summary:

   - Introduce configfs-tsm as a shared ABI for confidential computing
     attestation reports

   - Convert sev-guest to additionally support configfs-tsm alongside
     its vendor specific ioctl()

   - Added signed attestation report retrieval to the tdx-guest driver

2c40c1c6ad USB/Thunderbolt changes for 6.7-rc1 
Here is the "big" set of USB and Thunderbolt changes for 6.7-rc1.
 Nothing really major in here, just lots of constant development for new
 hardware.  Included in here are:
   - Thunderbolt (i.e. USB4) fixes for reported issues and support for
     new hardware types and devices
   - USB typec additions of new drivers and cleanups for some existing
     ones
   - xhci cleanups and expanded tracing support and some platform
     specific updates
   - USB "La Jolla Cove Adapter (LJCA)" support added, and the gpio, spi,
     and i2c drivers for that type of device (all acked by the respective
     subsystem maintainers.)
   - lots of USB gadget driver updates and cleanups
   - new USB dwc3 platforms supported, as well as other dwc3 fixes and
     cleanups
   - USB chipidea driver updates
   - other smaller driver cleanups and additions, full details in the
     shortlog
 
 All of these have been in the linux-next tree for a while with no
 reported problems, EXCEPT for some merge conflicts that you will run
 into in your tree.  2 of them are in device-tree files, which will be
 trivial to resolve (accept both sides), and the last in the
 drivers/gpio/gpio-ljca.c file, in the remove callback, resolution should

7269cba53d tee: optee: Fix supplicant based device enumeration 
Currently supplicant dependent optee device enumeration only registers
devices whenever tee-supplicant is invoked for the first time. But it
forgets to remove devices when tee-supplicant daemon stops running and
closes its context gracefully. This leads to following error for fTPM
driver during reboot/shutdown:

[   73.466791] tpm tpm0: ftpm_tee_tpm_op_send: SUBMIT_COMMAND invoke error: 0xffff3024

Fix this by adding an attribute for supplicant dependent devices so that
the user-space service can detect and detach supplicant devices before
closing the supplicant:

$ for dev in /sys/bus/tee/devices/*; do if [[ -f "$dev/need_supplicant" && -f "$dev/driver/unbind" ]]; \
      then echo $(basename "$dev") > $dev/driver/unbind; fi done

571d91dcad perf: Add branch stack counters 
Currently, the additional information of a branch entry is stored in a
u64 space. With more and more information added, the space is running
out. For example, the information of occurrences of events will be added
for each branch.

Two places were suggested to append the counters.
https://lore.kernel.org/lkml/20230802215814.GH231007@hirez.programming.kicks-ass.net/
One place is right after the flags of each branch entry. It changes the
existing struct perf_branch_entry. The later ARCH specific
implementation has to be really careful to consistently pick
the right struct.
The other place is right after the entire struct perf_branch_stack.
The disadvantage is that the pointer of the extra space has to be
recorded. The common interface perf_sample_save_brstack() has to be
updated.

The latter is much straightforward, and should be easily understood and
maintained. It is implemented in the patch.

Add a new branch sample type, PERF_SAMPLE_BRANCH_COUNTERS, to indicate
the event which is recorded in the branch info.

The "u64 counters" may store the occurrences of several events. The
information regarding the number of events/counters and the width of
each counter should be exposed via sysfs as a reference for the perf
tool. Define the branch_counter_nr and branch_counter_width ABI here.
The support will be implemented later in the Intel-specific patch.

Add the attribute `rp2svc` to the `qat` attribute group. This provides a
way for a user to query a specific ring pair for the type of service
that is currently configured for.

When read, the service will be returned for the defined ring pair.

db74e16258 crypto: qat - add rate limiting sysfs interface 
Add an interface for the rate limiting feature which allows to add,
remove and modify a QAT SLA (Service Level Agreement).

This adds a new sysfs attribute group, `qat_rl`, which can be accessed
from /sys/bus/pci/devices/<BUS:DEV:FUNCTION> with the following
hierarchy:
    |-+ qat_rl
      |---- id  (RW) # SLA identifier
      |---- cir (RW) # Committed Information Rate
      |---- pir (RW) # Peak Information Rate
      |---- srv (RW) # Service to be rate limited
      |---- rp  (RW) (HEX) # Ring pairs to be rate limited
      |---- cap_rem  (RW)  # Remaining capability for a service
      |---- sla_op   (WO)  # Allows to perform an operation on an SLA

The API works by setting the appropriate RW attributes and then
issuing a command through the `sla_op`. For example, to create an SLA, a
user needs to input the necessary data into the attributes cir, pir, srv
and rp and then write into `sla_op` the command `add` to execute the
operation.
The API also provides `cap_rem` attribute to get information about
the remaining device capability within a certain service which is
required when setting an SLA.

b4b6cc10c6 IIO: 1st set of new device support, features and cleanup for 6.7 
Particularly great to see a resolver driver move out of staging via a
 massive set of changes.  Only took 13 years :)
 
 One small patch added then reverted due to a report of test breakage
 (ashai-kasei,ak8975: Drop deprecated enums.)
 
 An immutable branch was used for some hid-senors changes in case
 there was a need to take them into the HID tree as well.
 
 New device support
 -----------------
 
 adi,hmc425a
   - Add support for HMC540SLP3E broadband 4-bit digital attenuator.
 kionix,kx022a
   - Add support for the kx132-1211 accelerometer. Require significant
     driver rework to enable this including add a chip type specific
     structure to deal with the chip differences.
   - Add support for the kx132acr-lbz accelerometer (subset of the kx022a
     feature set).
 lltc,ltc2309
   - New driver for this 8 channel ADC.
 microchip,mcp3911
   - Add support for rest of mcp391x family of ADCs (there are various
     differences beyond simple channel count variation.
     Series includes some general driver cleanup.
 microchip,mcp3564
   - New driver for MCP3461, MCP3462, MCP3464, MCP3541, MCP3562, MCP3564
     and their R variants of 16/24bit ADCs. A few minor fixed followed.
 rohm,bu1390
   - New driver for this pressure sensor.
 
 Staging graduation
 ------------------
 
 adi,ad1210 (after 13 or so years :)
   - More or less a complete (step-wise) rewrite of this resolver driver
     to bring it up to date with modern IIO standards.  The fault signal
     handling mapping to event channels was particularly complex and
     significant part of the changes.
 
 Features
 --------
 
 iio-core
  - Add chromacity and color temperature channel types.
 adi,ad7192
   - Oversampling ratio control (called fast settling in datasheet).

   - Add core support and then driver support for delta angle and delta
     velocity channels. These are intended for summation to establish
     angle and velocity changes over larger timescales.  Fix was
     needed for alignment after the temperature channel.  Further fix
     reduced set of devices for which the buffer support was applicable
     as seems burst reads don't cover these on all devices.
 hid-sensors-als
   - Chromacity and color temperatures support including in amd sfh.
 stx104
   - Add support for counter subsystem to this multipurpose device.
 ti,twl6030

     approaches.
 Similar cleanup to sets of drivers.
   - Stop platform remove callbacks returning anything by using the
     temporary remove_new() callback.
   - Use i2c_get_match_data() to cope nicely with all types of ID table
     entry.
   - Use device_get_match_data() for various platform device to cope
     with more types of firmware.
   - Convert from enum to pointer in ID tables allowing use of
     i2c_get_match_data().

 docs
   - Better description of the ordering requirements etc for
     available_scan_masks.
 tools
   - Handle alignment of mixed sizes where the last element isn't the biggest

     in the match tables.
 amlogic,meson
   - Expand error logging during probe.
 invensense,mpu6050
   - Support level-shifter control. Whilst no one is sure exactly what this
     is doing it is needed for some old boards.
   - Document mount-matrix dt-binding.
 mediatek,mt6577
   - Use devm_clk_get_enabled() to replace open coded version and move
     everything over to being device managed. Drop now empty remove()
     callback. Fix follows to put the drvdata back.
   - Use dev_err_probe() for error reporting in probe() callback.
 memsic,mxc4005
   - Add of_match_table.

70e6f7e2b9 configfs-tsm: Introduce a shared ABI for attestation reports 
One of the common operations of a TSM (Trusted Security Module) is to
provide a way for a TVM (confidential computing guest execution
environment) to take a measurement of its launch state, sign it and
submit it to a verifying party. Upon successful attestation that
verifies the integrity of the TVM additional secrets may be deployed.
The concept is common across TSMs, but the implementations are
unfortunately vendor specific. While the industry grapples with a common
definition of this attestation format [1], Linux need not make this
problem worse by defining a new ABI per TSM that wants to perform a
similar operation. The current momentum has been to invent new ioctl-ABI
per TSM per function which at best is an abdication of the kernel's
responsibility to make common infrastructure concepts share common ABI.

The proposal, targeted to conceptually work with TDX, SEV-SNP, COVE if
not more, is to define a configfs interface to retrieve the TSM-specific
blob.

    report=/sys/kernel/config/tsm/report/report0
    mkdir $report
    dd if=binary_userdata_plus_nonce > $report/inblob
    hexdump $report/outblob

This approach later allows for the standardization of the attestation
blob format without needing to invent a new ABI. Once standardization
happens the standard format can be emitted by $report/outblob and
indicated by $report/provider, or a new attribute like
"$report/tcg_coco_report" can emit the standard format alongside the
vendor format.

Review of previous iterations of this interface identified that there is
a need to scale report generation for multiple container environments
[2]. Configfs enables a model where each container can bind mount one or
more report generation item instances. Still, within a container only a
single thread can be manipulating a given configuration instance at a
time. A 'generation' count is provided to detect conflicts between
multiple threads racing to configure a report instance.

The SEV-SNP concepts of "extended reports" and "privilege levels" are
optionally enabled by selecting 'tsm_report_ext_type' at register_tsm()
time. The expectation is that those concepts are generic enough that
they may be adopted by other TSM implementations. In other words,
configfs-tsm aims to address a superset of TSM specific functionality
with a common ABI where attributes may appear, or not appear, based on
the set of concepts the implementation supports.

59de2a56d1 usb: typec: Link enumerated USB devices with Type-C partner 
Adding functions that USB hub code can use to inform the
Type-C class about connected USB devices.

Once taken into use, it will allow the Type-C port drivers
to power off components that are not needed, for example if
USB2 device is enumerated, everything that is only relevant
for USB3 (retimers, etc.), can be powered off.

This will also create a symlink "typec" for the USB devices
pointing to the USB Type-C partner device.

d807f0240c crypto: qat - add cnv_errors debugfs file 
The Compress and Verify (CnV) feature check and ensures data integrity
in the compression operation. The implementation of CnV keeps a record
of the CnV errors that have occurred since the driver was loaded.

Expose CnV error stats by providing the "cnv_errors" file under
debugfs. This includes the number of errors detected up to now and
the type of the last error. The error count is provided on a per
Acceleration Engine basis and it is reset every time the driver is loaded.

e079231676 crypto: qat - add pm_status debugfs file 
QAT devices implement a mechanism that allows them to go autonomously
to a low power state depending on the load.

Expose power management info by providing the "pm_status" file under
debugfs. This includes PM state, PM event log, PM event counters, PM HW
CSRs, per-resource type constrain counters and per-domain power gating
status specific to the QAT device.

This information is retrieved from (1) the FW by means of
ICP_QAT_FW_PM_INFO command, (2) CSRs and (3) counters collected by the
device driver.

In addition, add logic to keep track and report power management event
interrupts and acks/nacks sent to FW to allow/prevent state transitions.

318d97849f platform/x86: think-lmi: Add bulk save feature 
On Lenovo platforms there is a limitation in the number of times an
attribute can be saved. This is an architectural limitation and it limits
the number of attributes that can be modified to 48.
A solution for this is instead of the attribute being saved after every
modification allow a user to bulk set the attributes and then trigger a
final save. This allows unlimited attributes.

This patch introduces a save_settings attribute that can be configured to
either single or bulk mode by the user.
Single mode is the default but customers who want to avoid the 48
attribute limit can enable bulk mode.

Displaying the save_settings attribute will display the enabled mode.

When in bulk mode writing 'save' to the save_settings attribute will
trigger a save. Once this has been done a reboot is required before more
attributes can be modified.

37b14f2dfa crypto: qat - enable dc chaining service 
QAT GEN4 devices support chained compression operations. These
allow, with a single request to firmware, to hash then compress
data.

Extend the configuration to enable such mode. The cfg_services
operations in sysfs are extended to allow the string "dcc". When
selected, the driver downloads to the device both the symmetric
crypto and the compression firmware images and sends an admin message
to firmware which enables `chained` operations.
In addition, it sets the device's capabilities as the combination
of compression and symmetric crypto capabilities, while excluding
the ICP_ACCEL_CAPABILITIES_CRYPTO_SYMMETRIC bit to indicate
that in this mode, symmetric crypto instances are not supported.

When "dcc" is enabled, the device will handle compression requests
as if the "dc" configuration is loaded ("dcc" is a variation of "dc")
and the driver will register the acomp algorithms.

As for the other extended configurations, "dcc" is only available for
qat_4xxx devices and the chaining service will be only accessible from
user space.
