- Add support for running the kernel in a SEV-SNP guest, over a Secure
VM Service Module (SVSM).
When running over a SVSM, different services can run at different
protection levels, apart from the guest OS but still within the
secure SNP environment. They can provide services to the guest, like
a vTPM, for example.
This series adds the required facilities to interface with such a SVSM
module.

driver core: auxiliary bus: show auxiliary device IRQs
PCI subfunctions (SF) are anchored on the auxiliary bus. PCI physical and virtual functions are anchored on the PCI bus. The irq information of each such function is visible to users via sysfs directory "msi_irqs" containing files for each irq entry. However, for PCI SFs such information is unavailable. Due to this users have no visibility on IRQs used by the SFs. Secondly, an SF can be multi function device supporting rdma, netdevice and more. Without irq information at the bus level, the user is unable to view or use the affinity of the SF IRQs. Hence to match to the equivalent PCI PFs and VFs, add "irqs" directory, for supporting auxiliary devices, containing file for each irq entry. For example: $ ls /sys/bus/auxiliary/devices/mlx5_core.sf.1/irqs/ 50 51 52 53 54 55 56 57 58 Cc: Simon Horman <horms@kernel.org> Reviewed-by: Przemek Kitszel <przemyslaw.kitszel@intel.com> Reviewed-by: Parav Pandit <parav@nvidia.com> Reviewed-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Shay Drory <shayd@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com> --- v9-v10: - remove Przemek RB - add name field to auxiliary_irq_info (Greg and Przemek) - handle bogus IRQ in auxiliary_device_sysfs_irq_remove (Greg) v8-v9: - add Przemek RB - use guard() in auxiliary_irq_dir_prepare (Paolo) v7-v8: - use cleanup.h for info and name fields (Greg) - correct error flow in auxiliary_irq_dir_prepare (Przemek) - add documentation for new fields of auxiliary_device (Simon) v6-v7: - dynamically creating irqs directory when first irq file created (Greg) - removed irqs flag and simplified the dev_add() API (Greg) - move sysfs related new code to a new auxiliary_sysfs.c file (Greg) v5-v6: - removed concept of shared and exclusive and hence global xarray (Greg) v4-v5: - restore global mutex and replace refcount_t with simple integer (Greg) v3->4: - remove global mutex (Przemek) v2->v3: - fix function declaration in case SYSFS isn't defined v1->v2: - move #ifdefs from drivers/base/auxiliary.c to include/linux/auxiliary_bus.h (Greg) - use EXPORT_SYMBOL_GPL instead of EXPORT_SYMBOL (Greg) - Fix kzalloc(ref) to kzalloc(*ref) (Simon) - Add return description in auxiliary_device_sysfs_irq_add() kdoc (Simon) - Fix auxiliary_irq_mode_show doc (kernel test boot) |

cxl/memdev: Replace ENXIO with EBUSY for inject poison limit reached
The CXL driver provides a debugfs interface offering users the ability to inject and clear poison to a memdev. Once a user has injected up to the devices limit further injection requests fail with ENXIO until a clear poison is issued. Users may not have device specs in hand or may want to intentionally hit the limit and then clear. Replace the usual ENXIO return status with EBUSY so users can recognize this failure.

nvmem: core: Implement force_ro sysfs attribute
Implement "force_ro" sysfs attribute to allow users to set read-write devices as read-only and back to read-write from userspace. The choice of the name is based on MMC core 'force_ro' attribute. This solves a situation where an AT24 I2C EEPROM with GPIO based nWP signal may have to be occasionally updated. Such I2C EEPROM device is usually set as read-only during most of the regular system operation, but in case it has to be updated in a controlled manner, it could be unlocked using this new "force_ro" sysfs attribute and then re-locked again. The "read-only" DT property and config->read_only configuration is respected and is used to set default state of the device, read-only or read-write, for devices which do implement .reg_write function. For devices which do not implement .reg_write function, the device is unconditionally read-only and the "force_ro" attribute is not visible.

backlight: Add BACKLIGHT_POWER_ constants for power states
Duplicate FB_BLANK_ constants as BACKLIGHT_POWER__ constants in the backlight header file. Allows backlight drivers to avoid including the fbdev header file and removes a compile-time dependency between the two subsystems. The new BACKLIGHT_POWER_ constants have the same values as their FB_BLANK_ counterparts. Hence UAPI and internal semantics do not change. The backlight drivers can be converted one by one. Each instance of FB_BLANK_UNBLANK becomes BACKLIGHT_POWER_ON, each of FB_BLANK_POWERDOWN becomes BACKLIGHT_POWER_OFF, and FB_BLANK_NORMAL becomes BACKLIGHT_POWER_REDUCED. Backlight code or drivers do not use FB_BLANK_VSYNC_SUSPEND and FB_BLANK_HSYNC_SUSPEND, so no new constants for these are being added. The semantics of FB_BLANK_NORMAL appear inconsistent. In fbdev, NORMAL means display off with sync enabled. In backlight code, this translates to turn the backlight off, but some drivers interpret it as backlight on. So we keep the current code as is, but mark BACKLIGHT_POWER_REDUCED as deprecated. Drivers should be fixed and the constant removed. This affects ams369fg06 and a few DRM panel drivers. v2: - rename BL_CORE_ power constants to BACKLIGHT_POWER_ (Sam) - fix documentation Signed-off-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Daniel Thompson <daniel.thompson@linaro.org> Link: https://lore.kernel.org/r/20240624152033.25016-2-tzimmermann@suse.de Signed-off-by: Lee Jones <lee@kernel.org> |

misc: keba: Add basic KEBA CP500 system FPGA support
The KEBA CP500 system FPGA is a PCIe device, which consists of multiple IP cores. Every IP core has its own auxiliary driver. The cp500 driver registers an auxiliary device for each device and the corresponding drivers are loaded by the Linux driver infrastructure. Currently 3 variants of this device exists. Every variant has its own PCI device ID, which is used to determine the list of available IP cores. In this first version only the auxiliary device for the I2C controller is registered. Besides the auxiliary device registration some other basic functions of the FPGA are implemented; e.g, FPGA version sysfs file, keep FPGA configuration on reset sysfs file, error message for errors on the internal AXI bus of the FPGA.

xfs: grant heads track byte counts, not LSNs
The grant heads in the log track the space reserved in the log for
running transactions. They do this by tracking how far ahead of the
tail that the reservation has reached, and the units for doing this
are {cycle,bytes} for the reserve head rather than {cycle,blocks}
which are normal used by LSNs.
This is annoyingly complex because we have to split, crack and
combined these tuples for any calculation we do to determine log
space and targets. This is computationally expensive as well as
difficult to do atomically and locklessly, as well as limiting the
size of the log to 2^32 bytes.
Really, though, all the grant heads are tracking is how much space
is currently available for use in the log. We can track this as a
simply byte count - we just don't care what the actual physical
location in the log the head and tail are at, just how much space we
have remaining before the head and tail overlap.
So, convert the grant heads to track the byte reservations that are
active rather than the current (cycle, offset) tuples. This means an
empty log has zero bytes consumed, and a full log is when the
reservations reach the size of the log minus the space consumed by
the AIL.
This greatly simplifies the accounting and checks for whether there
is space available. We no longer need to crack or combine LSNs to
determine how much space the log has left, nor do we need to look at
the head or tail of the log to determine how close to full we are.
There is, however, a complexity that needs to be handled. We know
how much space is being tracked in the AIL now via log->l_tail_space
and the log tickets track active reservations and return the unused
portions to the grant heads when ungranted. Unfortunately, we don't
track the used portion of the grant, so when we transfer log items
from the CIL to the AIL, the space accounted to the grant heads is
transferred to the log tail space. Hence when we move the AIL head
forwards on item insert, we have to remove that space from the grant
heads.
We also remove the xlog_verify_grant_tail() debug function as it is
no longer useful. The check it performs has been racy since delayed
logging was introduced, but now it is clearly only detecting false
positives so remove it.
The result of this substantially simpler accounting algorithm is an
increase in sustained transaction rate from ~1.3 million
transactions/s to ~1.9 million transactions/s with no increase in
CPU usage. We also remove the 32 bit space limitation on the grant
heads, which will allow us to increase the journal size beyond 2GB
in future.
Note that this renames the sysfs files exposing the log grant space
now that the values are exported in bytes. This allows xfstests
to auto-detect the old or new ABI.
[hch: move xlog_grant_sub_space out of line,
update the xlog_grant_{add,sub}_space prototypes,
rename the sysfs files to allow auto-detection in xfstests]

livepatch: Add "replace" sysfs attribute
There are situations when it might make sense to combine livepatches with and without the atomic replace on the same system. For example, the livepatch without the atomic replace might provide a hotfix or extra tuning. Managing livepatches on such systems might be challenging. And the information which of the installed livepatches do not use the atomic replace would be useful. Add new sysfs interface 'replace'.

cpumask: Add enabled cpumask for present CPUs that can be brought online
The 'offline' file in sysfs shows all offline CPUs, including those that aren't present. User-space is expected to remove not-present CPUs from this list to learn which CPUs could be brought online. CPUs can be present but not-enabled. These CPUs can't be brought online until the firmware policy changes, which comes with an ACPI notification that will register the CPUs. With only the offline and present files, user-space is unable to determine which CPUs it can try to bring online. Add a new CPU mask that shows this based on all the registered CPUs.

xhci: dbc: Allow users to modify DbC poll interval via sysfs
xhci DbC driver polls the host controller for DbC events at a reduced rate when DbC is enabled but there are no active data transfers. Allow users to modify this reduced poll interval via dbc_poll_interval_ms sysfs entry. Unit is milliseconds and accepted range is 0 to 5000. Max interval of 5000 ms is selected as it matches the common 5 second timeout used in usb stack. Default value is 64 milliseconds. A long interval is useful when users know there won't be any activity on systems connected via DbC for long periods, and want to avoid battery drainage due to unnecessary CPU usage. Example being Android Debugger (ADB) usage over DbC on ChromeOS systems running Android Runtime.

block: Add core atomic write support
Add atomic write support, as follows:
- add helper functions to get request_queue atomic write limits
- report request_queue atomic write support limits to sysfs and update Doc
- support to safely merge atomic writes
- deal with splitting atomic writes
- misc helper functions
- add a per-request atomic write flag
New request_queue limits are added, as follows:
- atomic_write_hw_max is set by the block driver and is the maximum length
of an atomic write which the device may support. It is not
necessarily a power-of-2.
- atomic_write_max_sectors is derived from atomic_write_hw_max_sectors and
max_hw_sectors. It is always a power-of-2. Atomic writes may be merged,
and atomic_write_max_sectors would be the limit on a merged atomic write
request size. This value is not capped at max_sectors, as the value in
max_sectors can be controlled from userspace, and it would only cause
trouble if userspace could limit atomic_write_unit_max_bytes and the
other atomic write limits.
- atomic_write_hw_unit_{min,max} are set by the block driver and are the
min/max length of an atomic write unit which the device may support. They
both must be a power-of-2. Typically atomic_write_hw_unit_max will hold
the same value as atomic_write_hw_max.
- atomic_write_unit_{min,max} are derived from
atomic_write_hw_unit_{min,max}, max_hw_sectors, and block core limits.
Both min and max values must be a power-of-2.
- atomic_write_hw_boundary is set by the block driver. If non-zero, it
indicates an LBA space boundary at which an atomic write straddles no
longer is atomically executed by the disk. The value must be a
power-of-2. Note that it would be acceptable to enforce a rule that
atomic_write_hw_boundary_sectors is a multiple of
atomic_write_hw_unit_max, but the resultant code would be more
complicated.
All atomic writes limits are by default set 0 to indicate no atomic write
support. Even though it is assumed by Linux that a logical block can always
be atomically written, we ignore this as it is not of particular interest.
Stacked devices are just not supported either for now.
An atomic write must always be submitted to the block driver as part of a
single request. As such, only a single BIO must be submitted to the block
layer for an atomic write. When a single atomic write BIO is submitted, it
cannot be split. As such, atomic_write_unit_{max, min}_bytes are limited
by the maximum guaranteed BIO size which will not be required to be split.
This max size is calculated by request_queue max segments and the number
of bvecs a BIO can fit, BIO_MAX_VECS. Currently we rely on userspace
issuing a write with iovcnt=1 for pwritev2() - as such, we can rely on each
segment containing PAGE_SIZE of data, apart from the first+last, which each
can fit logical block size of data. The first+last will be LBS
length/aligned as we rely on direct IO alignment rules also.
New sysfs files are added to report the following atomic write limits:
- atomic_write_unit_max_bytes - same as atomic_write_unit_max_sectors in
bytes
- atomic_write_unit_min_bytes - same as atomic_write_unit_min_sectors in
bytes
- atomic_write_boundary_bytes - same as atomic_write_hw_boundary_sectors in
bytes
- atomic_write_max_bytes - same as atomic_write_max_sectors in bytes
Atomic writes may only be merged with other atomic writes and only under
the following conditions:
- total resultant request length <= atomic_write_max_bytes
- the merged write does not straddle a boundary
Helper function bdev_can_atomic_write() is added to indicate whether
atomic writes may be issued to a bdev. If a bdev is a partition, the
partition start must be aligned with both atomic_write_unit_min_sectors
and atomic_write_hw_boundary_sectors.
FSes will rely on the block layer to validate that an atomic write BIO
submitted will be of valid size, so add blk_validate_atomic_write_op_size()
for this purpose. Userspace expects an atomic write which is of invalid
size to be rejected with -EINVAL, so add BLK_STS_INVAL for this. Also use
BLK_STS_INVAL for when a BIO needs to be split, as this should mean an
invalid size BIO.
Flag REQ_ATOMIC is used for indicating an atomic write.

x86/sev: Extend the config-fs attestation support for an SVSM
When an SVSM is present, the guest can also request attestation reports
from it. These SVSM attestation reports can be used to attest the SVSM
and any services running within the SVSM.
Extend the config-fs attestation support to provide such. This involves
creating four new config-fs attributes:
- 'service-provider' (input)
This attribute is used to determine whether the attestation request
should be sent to the specified service provider or to the SEV
firmware. The SVSM service provider is represented by the value
'svsm'.
- 'service_guid' (input)
Used for requesting the attestation of a single service within the
service provider. A null GUID implies that the SVSM_ATTEST_SERVICES
call should be used to request the attestation report. A non-null
GUID implies that the SVSM_ATTEST_SINGLE_SERVICE call should be used.
- 'service_manifest_version' (input)
Used with the SVSM_ATTEST_SINGLE_SERVICE call, the service version
represents a specific service manifest version be used for the
attestation report.
- 'manifestblob' (output)
Used to return the service manifest associated with the attestation
report.
Only display these new attributes when running under an SVSM.

x86/sev: Provide guest VMPL level to userspace
Requesting an attestation report from userspace involves providing the VMPL level for the report. Currently any value from 0-3 is valid because Linux enforces running at VMPL0. When an SVSM is present, though, Linux will not be running at VMPL0 and only VMPL values starting at the VMPL level Linux is running at to 3 are valid. In order to allow userspace to determine the minimum VMPL value that can be supplied to an attestation report, create a sysfs entry that can be used to retrieve the current VMPL level of the kernel.

perf tools fixes and improvements for v6.10:
- Add Kan Liang to MAINTAINERS as a perf tools reviewer.
- Add support for using the 'capstone' disassembler library in various tools,
such as 'perf script' and 'perf annotate'. This is an alternative for the
use of the 'xed' and 'objdump' disassemblers.
- Data-type profiling improvements:
Resolve types for a->b->c by backtracking the assignments until it finds
DWARF info for one of those members
Support for global variables, keeping a cache to speed up lookups.
Handle the 'call' instruction, dealing with effects on registers and handling
its return when tracking register data types.
Handle x86's segment based addressing like %gs:0x28, to support things like
per CPU variables, the stack canary, etc.
Data-type profiling got big speedups when using capstone for disassembling.
The objdump outoput parsing method is left as a fallback when capstone fails or
isn't available. There are patches posted for 6.11 that to use a LLVM
disassembler.
Support event group display in the TUI when annotating types with --data-type,
for instance to show memory load and store events for the data type fields.
Optimize the 'perf annotate' data structures, reducing memory usage.
Add a initial 'perf test' for 'perf annotate', checking that a target symbol
appears on the output, specifying objdump via the command line, etc.
- Integrate the shellcheck utility with the build of perf to allow catching
shell problems early in areas such as 'perf test', 'perf trace' scrape
scripts, etc.
- Add 'uretprobe' variant in the 'perf bench uprobe' tool.
- Add script to run instances of 'perf script' in parallel.
- Allow parsing tracepoint names that start with digits, such as
9p/9p_client_req, etc. Make sure 'perf test' tests it even on systems
where those tracepoints aren't available.
Vendor Events:

Pull perf tools updates from Arnaldo Carvalho de Melo:
"General:
- Integrate the shellcheck utility with the build of perf to allow
catching shell problems early in areas such as 'perf test', 'perf
trace' scrape scripts, etc
- Add 'uretprobe' variant in the 'perf bench uprobe' tool
- Add script to run instances of 'perf script' in parallel
- Allow parsing tracepoint names that start with digits, such as
9p/9p_client_req, etc. Make sure 'perf test' tests it even on
systems where those tracepoints aren't available
- Add Kan Liang to MAINTAINERS as a perf tools reviewer
- Add support for using the 'capstone' disassembler library in
various tools, such as 'perf script' and 'perf annotate'. This is
an alternative for the use of the 'xed' and 'objdump' disassemblers
Data-type profiling improvements:
- Resolve types for a->b->c by backtracking the assignments until it
finds DWARF info for one of those members
- Support for global variables, keeping a cache to speed up lookups
- Handle the 'call' instruction, dealing with effects on registers
and handling its return when tracking register data types
- Handle x86's segment based addressing like %gs:0x28, to support
things like per CPU variables, the stack canary, etc
- Data-type profiling got big speedups when using capstone for
disassembling. The objdump outoput parsing method is left as a
fallback when capstone fails or isn't available. There are patches
posted for 6.11 that to use a LLVM disassembler
- Support event group display in the TUI when annotating types with
--data-type, for instance to show memory load and store events for
the data type fields
- Optimize the 'perf annotate' data structures, reducing memory usage
- Add a initial 'perf test' for 'perf annotate', checking that a
target symbol appears on the output, specifying objdump via the
command line, etc
Vendor Events:
- Update Intel JSON files for Cascade Lake X, Emerald Rapids, Grand
Ridge, Ice Lake X, Lunar Lake, Meteor Lake, Sapphire Rapids, Sierra

f2fs update for 6.10-rc1
In this round, we've tried to address some performance issues on zoned storage
such as direct IO and write_hints. In addition, we've migrated some IO paths
using folio. Meanwhile, there are multiple bug fixes in the compression paths,
sanity check conditions, and error handlers.
Enhancement:
- allow direct io of pinned files for zoned storage
- assign the write hint per stream by default
- convert read paths and test_writeback to folio
- avoid allocating WARM_DATA segment for direct IO
Bug fix:
- fix false alarm on invalid block address
- fix to add missing iput() in gc_data_segment()
- fix to release node block count in error path of f2fs_new_node_page()
- compress: don't allow unaligned truncation on released compress inode
- compress: fix to cover {reserve,release}_compress_blocks() w/ cp_rwsem lock
- compress: fix error path of inc_valid_block_count()
- compress: fix to update i_compr_blocks correctly
- fix block migration when section is not aligned to pow2
- don't trigger OPU on pinfile for direct IO
- fix to do sanity check on i_xattr_nid in sanity_check_inode()
- write missing last sum blk of file pinning section
- clear writeback when compression failed
- fix to adjust appropirate defragment pg_end
As usual, there are several minor code clean-ups, and fixes to manage missing
corner cases in the error paths.

powerpc updates for 6.10
- Enable BPF Kernel Functions (kfuncs) in the powerpc BPF JIT.
- Allow per-process DEXCR (Dynamic Execution Control Register) settings via
prctl, notably NPHIE which controls hashst/hashchk for ROP protection.
- Install powerpc selftests in sub-directories. Note this changes the way
run_kselftest.sh needs to be invoked for powerpc selftests.
- Change fadump (Firmware Assisted Dump) to better handle memory add/remove.
- Add support for passing additional parameters to the fadump kernel.
- Add support for updating the kdump image on CPU/memory add/remove events.
- Other small features, cleanups and fixes.

blk-throttle: remove CONFIG_BLK_DEV_THROTTLING_LOW
One the one hand, it's marked EXPERIMENTAL since 2017, and looks like there are no users since then, and no testers and no developers, it's just not active at all. On the other hand, even if the config is disabled, there are still many fields in throtl_grp and throtl_data and many functions that are only used for throtl low. At last, currently blk-throtl is initialized during disk initialization, and destroyed during disk removal, and it exposes many functions to be called directly from block layer.

leds: trigger: pattern: Add support for hrtimer
Currently, led pattern trigger uses timer_list to schedule brightness changing. As we know from timer_list API [1], it's not accurate to milliseconds and depends on HZ granularity. Example: "0 10 0 0 50 10 50 0 100 10 100 0 150 10 150 0 200 10 200 0 250 10 250 0", we expect it to be 60ms long, but it can actually be up to ~120ms (add ~10ms for each pattern when HZ == 100). But sometimes, userspace needs time accurate led patterns to make sure that pattern will be executed during expected time slot. To achieve this goal the patch introduces optional hrtimer usage for led trigger pattern, because hrtimer is microseconds accurate timer.

powerpc/fadump: add hotplug_ready sysfs interface
The elfcorehdr describes the CPUs and memory of the crashed kernel to
the kernel that captures the dump, known as the second or fadump kernel.
The elfcorehdr needs to be updated if the system's memory changes due to
memory hotplug or online/offline events.
Currently, memory hotplug events are monitored in userspace by udev
rules, and fadump is re-registered, which recreates the elfcorehdr with
the latest available memory in the system.
However, the previous patch ("powerpc: make fadump resilient with memory
add/remove events") moved the creation of elfcorehdr to the second or
fadump kernel. This eliminates the need to regenerate the elfcorehdr
during memory hotplug or online/offline events.
Create a sysfs entry at /sys/kernel/fadump/hotplug_ready to let
userspace know that fadump re-registration is not required for memory
add/remove events.

platform/x86: wmi: Add MSI WMI Platform driver
Add a new driver for the MSI WMI Platform interface. The underlying ACPI WMI interface supports many features, but so far only reading of fan speed sensors is implemented. The driver was reverse-engineered based on a user request to the lm-sensors project, see the github issue for details. The ACPI WMI interface used by this driver seems to use the same embedded controller interface as the msi-ec driver, but supports automatic discovery of supported machines without relying on a DMI whitelist. The driver was tested by the user who created the github issue.

drm/xe/hwmon: Add infra to support card power and energy attributes
Add infra to support card power and energy attributes through channel 0.
Package attributes will be now exposed through channel 1 rather than
channel 0 as shown below.
Channel 0 i.e power1/energy1_xxx used for card and
channel 1 i.e power2/energy2_xxx used for package power,energy attributes.
power1/curr1_crit and in0_input are moved to channel 1, i.e.
power2/curr2_crit and in1_input as these are available for package only.
This would be needed for future platforms where they might be
separate registers for package and card power and energy.
Each discrete GPU supported by Xe driver, would have a directory in
/sys/class/hwmon/ with multiple channels under it.
Each channel would have attributes for power, energy etc.
Ex: /sys/class/hwmon/hwmon2/power1_max
/power1_label
/energy1_input
/energy1_label
Attributes will have a label to get more description of it.
Labelling is as below.
power1_label/energy1_label - "card",
power2_label/energy2_label - "pkg".
v2: Fix checkpatch errors.
v3:
- Update intel-xe-hwmon documentation. (Riana, Badal)
- Rename hwmon card channel enum from CHANNEL_PLATFORM
to CHANNEL_CARD. (Riana)
v4:
- Remove unrelated changes from patch. (Anshuman)
- Fix typo in commit msg.

- Update commit message and intel-xe-hwmon documentation with "Xe"
instead of xe when using it as a name. (Rodrigo)

usb: misc: onboard_hub: rename to onboard_dev
This patch prepares onboad_hub to support non-hub devices by renaming the driver files and their content, the headers and their references. The comments and descriptions have been slightly modified to keep coherence and account for the specific cases that only affect onboard hubs (e.g. peer-hub). The "hub" variables in functions where "dev" (and similar names) variables already exist have been renamed to onboard_dev for clarity, which adds a few lines in cases where more than 80 characters are used. No new functionality has been added.

f2fs update for 6.9-rc1
In this round, there are a number of updates on mainly two areas: Zoned block
device support and Per-file compression. For example, we've found several issues
to support Zoned block device especially having large sections regarding to GC
and file pinning used for Android devices. In compression side, we've fixed many
corner race conditions that had broken the design assumption.
Enhancement:
- Support file pinning for Zoned block device having large section
- Enhance the data recovery after sudden power cut on Zoned block device
- Add more error injection cases to easily detect the kernel panics
- add a proc entry show the entire disk layout
- Improve various error paths paniced by BUG_ON in block allocation and GC
- support SEEK_DATA and SEEK_HOLE for compression files
Bug fix:
- fix to avoid use-after-free issue in f2fs_filemap_fault
- fix some race conditions to break the atomic write design assumption
- fix to truncate meta inode pages forcely
- resolve various per-file compression issues wrt the space management and
compression policies
- fix some swap-related bugs
In addition, we removed deprecated codes such as io_bits and heap_allocation,
and also fixed minor error handling routines with neat debugging messages.

Merge tag 'cxl-for-6.9' of git://git.kernel.org/pub/scm/linux/kernel/git/cxl/cxl
Pull CXL updates from Dan Williams:
"CXL has mechanisms to enumerate the performance characteristics of
memory devices. Those mechanisms allow Linux to build the equivalent
of ACPI SRAT, SLIT, and HMAT tables dynamically at runtime. That
capability is necessary because static ACPI can not represent dynamic
CXL configurations (and reconfigurations).
So, building on the v6.8 work to add "Quality of Service" enumeration,
this update plumbs CXL "access coordinates" (read/write access latency
and bandwidth) in all the same places that ACPI HMAT feeds similar
data. Follow-on patches from the -mm side can then use that data to
feed mechanisms like mm/memory-tiers.c. Greg has acked the touch to
drivers/base/.
The other feature update this cycle is support for CXL error injection
via the ACPI EINJ module. That facility enables injection of bus
protocol errors provided the user knows the magic address values to
insert in the interface. To hide that magic, and make this easier to
use, new error injection attributes were added to CXL debugfs. That
interface injects the errors relative to a CXL object rather than
require user tooling to know how to lookup and inject RCRB (Root
Complex Register Block) addresses into the raw EINJ debugfs interface.
It received some helpful review comments from Tony, but no explicit
acks from the ACPI side. The primary user visible change for existing
EINJ users is that they may find that einj.ko was already loaded by
cxl_core.ko. Previously, einj.ko was only loaded on demand.
The usual collection of miscellaneous cleanups are also present this
cycle.
Summary:
- Supplement ACPI HMAT reported memory performance with native CXL
memory performance enumeration
- Add support for CXL error injection via the ACPI EINJ mechanism
- Cleanup CXL DOE and CDAT integration
- Miscellaneous cleanups and fixes"

- Sumanth Korikkar has taught s390 to allocate hotplug-time page frames
from hotplugged memory rather than only from main memory. Series
"implement "memmap on memory" feature on s390".
- More folio conversions from Matthew Wilcox in the series
"Convert memcontrol charge moving to use folios"
"mm: convert mm counter to take a folio"
- Chengming Zhou has optimized zswap's rbtree locking, providing
significant reductions in system time and modest but measurable
reductions in overall runtimes. The series is "mm/zswap: optimize the
scalability of zswap rb-tree".
- Chengming Zhou has also provided the series "mm/zswap: optimize zswap
lru list" which provides measurable runtime benefits in some
swap-intensive situations.
- And Chengming Zhou further optimizes zswap in the series "mm/zswap:
optimize for dynamic zswap_pools". Measured improvements are modest.
- zswap cleanups and simplifications from Yosry Ahmed in the series "mm:
zswap: simplify zswap_swapoff()".
- In the series "Add DAX ABI for memmap_on_memory", Vishal Verma has
contributed several DAX cleanups as well as adding a sysfs tunable to
control the memmap_on_memory setting when the dax device is hotplugged
as system memory.
- Johannes Weiner has added the large series "mm: zswap: cleanups",
which does that.
- More DAMON work from SeongJae Park in the series
"mm/damon: make DAMON debugfs interface deprecation unignorable"
"selftests/damon: add more tests for core functionalities and corner cases"
"Docs/mm/damon: misc readability improvements"
"mm/damon: let DAMOS feeds and tame/auto-tune itself"
- In the series "mm/mempolicy: weighted interleave mempolicy and sysfs
extension" Rakie Kim has developed a new mempolicy interleaving policy
wherein we allocate memory across nodes in a weighted fashion rather
than uniformly. This is beneficial in heterogeneous memory environments
appearing with CXL.
- Christophe Leroy has contributed some cleanup and consolidation work
against the ARM pagetable dumping code in the series "mm: ptdump:
Refactor CONFIG_DEBUG_WX and check_wx_pages debugfs attribute".
- Luis Chamberlain has added some additional xarray selftesting in the
series "test_xarray: advanced API multi-index tests".
- Muhammad Usama Anjum has reworked the selftest code to make its
human-readable output conform to the TAP ("Test Anything Protocol")
format. Amongst other things, this opens up the use of third-party
tools to parse and process out selftesting results.
- Ryan Roberts has added fork()-time PTE batching of THP ptes in the
series "mm/memory: optimize fork() with PTE-mapped THP". Mainly
targeted at arm64, this significantly speeds up fork() when the process
has a large number of pte-mapped folios.
- David Hildenbrand also gets in on the THP pte batching game in his
series "mm/memory: optimize unmap/zap with PTE-mapped THP". It
implements batching during munmap() and other pte teardown situations.
The microbenchmark improvements are nice.
- And in the series "Transparent Contiguous PTEs for User Mappings" Ryan
Roberts further utilizes arm's pte's contiguous bit ("contpte
mappings"). Kernel build times on arm64 improved nicely. Ryan's series
"Address some contpte nits" provides some followup work.
- In the series "mm/hugetlb: Restore the reservation" Breno Leitao has
fixed an obscure hugetlb race which was causing unnecessary page faults.
He has also added a reproducer under the selftest code.
- In the series "selftests/mm: Output cleanups for the compaction test",
Mark Brown did what the title claims.
- Kinsey Ho has added the series "mm/mglru: code cleanup and refactoring".
- Even more zswap material from Nhat Pham. The series "fix and extend
zswap kselftests" does as claimed.
- In the series "Introduce cpu_dcache_is_aliasing() to fix DAX
regression" Mathieu Desnoyers has cleaned up and fixed rather a mess in
our handling of DAX on archiecctures which have virtually aliasing data
caches. The arm architecture is the main beneficiary.
- Lokesh Gidra's series "per-vma locks in userfaultfd" provides dramatic
improvements in worst-case mmap_lock hold times during certain
userfaultfd operations.
- Some page_owner enhancements and maintenance work from Oscar Salvador
in his series
"page_owner: print stacks and their outstanding allocations"
"page_owner: Fixup and cleanup"
- Uladzislau Rezki has contributed some vmalloc scalability improvements
in his series "Mitigate a vmap lock contention". It realizes a 12x
improvement for a certain microbenchmark.
- Some kexec/crash cleanup work from Baoquan He in the series "Split
crash out from kexec and clean up related config items".
- Some zsmalloc maintenance work from Chengming Zhou in the series
"mm/zsmalloc: fix and optimize objects/page migration"
"mm/zsmalloc: some cleanup for get/set_zspage_mapping()"
- Zi Yan has taught the MM to perform compaction on folios larger than
order=0. This a step along the path to implementaton of the merging of
large anonymous folios. The series is named "Enable >0 order folio
memory compaction".
- Christoph Hellwig has done quite a lot of cleanup work in the
pagecache writeback code in his series "convert write_cache_pages() to
an iterator".
- Some modest hugetlb cleanups and speedups in Vishal Moola's series
"Handle hugetlb faults under the VMA lock".
- Zi Yan has changed the page splitting code so we can split huge pages
into sizes other than order-0 to better utilize large folios. The
series is named "Split a folio to any lower order folios".
- David Hildenbrand has contributed the series "mm: remove
total_mapcount()", a cleanup.
- Matthew Wilcox has sought to improve the performance of bulk memory
freeing in his series "Rearrange batched folio freeing".
- Gang Li's series "hugetlb: parallelize hugetlb page init on boot"
provides large improvements in bootup times on large machines which are
configured to use large numbers of hugetlb pages.
- Matthew Wilcox's series "PageFlags cleanups" does that.
- Qi Zheng's series "minor fixes and supplement for ptdesc" does that
also. S390 is affected.
- Cleanups to our pagemap utility functions from Peter Xu in his series
"mm/treewide: Replace pXd_large() with pXd_leaf()".
- Nico Pache has fixed a few things with our hugepage selftests in his
series "selftests/mm: Improve Hugepage Test Handling in MM Selftests".
- Also, of course, many singleton patches to many things. Please see
the individual changelogs for details.

Documentation/ABI/testing/debugfs-cxl: Fix "Unexpected indentation"
Stephen reported that an htmldocs build hit:
Documentation/ABI/testing/debugfs-cxl:38: ERROR: Unexpected indentation.
It turns out that line was fine but the tool was unhappy about some line
breaks in the table of values to error types.
It turns out that:
make V=1 SPHINXDIRS="admin-guide" htmldocs
...can not be used to get more info about what is behind a documentation
build error. It was only pure luck that reflowing the text resulted in
an error message that seemed a imply a problem later on with line breaks
around the table.

Pull PCI updates from Bjorn Helgaas:
"Enumeration:
- Consolidate interrupt related code in irq.c (Ilpo Järvinen)
- Reduce kernel size by replacing sysfs resource macros with
functions (Ilpo Järvinen)
- Reduce kernel size by compiling sysfs support only when
CONFIG_SYSFS=y (Lukas Wunner)
- Avoid using Extended Tags on 3ware-9650SE Root Port to work around
an apparent hardware defect (Jörg Wedekind)
Resource management:
- Fix an MMIO mapping leak in pci_iounmap() (Philipp Stanner)
- Move pci_iomap.c and other PCI-specific devres code to drivers/pci
(Philipp Stanner)
- Consolidate PCI devres code in devres.c (Philipp Stanner)
Power management:
- Avoid D3cold on Asus B1400 PCI-NVMe bridge, where firmware doesn't
know how to return correctly to D0, and remove previous quirk that
wasn't as specific (Daniel Drake)
- Allow runtime PM when the driver enables it but doesn't need any
runtime PM callbacks (Raag Jadav)
- Drain runtime-idle callbacks before driver removal to avoid races
between .remove() and .runtime_idle(), which caused intermittent
page faults when the rtsx .runtime_idle() accessed registers that
its .remove() had already unmapped (Rafael J. Wysocki)
Virtualization:
- Avoid Secondary Bus Reset on LSI FW643 so it can be assigned to VMs
with VFIO, e.g., for professional audio software on many Apple
machines, at the cost of leaking state between VMs (Edmund Raile)
Error handling:
- Print all logged TLP Prefixes, not just the first, after AER or DPC
errors (Ilpo Järvinen)
- Quirk the DPC PIO log size for Intel Raptor Lake Root Ports, which
still don't advertise a legal size (Paul Menzel)
- Ignore expected DPC Surprise Down errors on hot removal (Smita
Koralahalli)
- Block runtime suspend while handling AER errors to avoid races that
prevent the device form being resumed from D3hot (Stanislaw
Gruszka)
Peer-to-peer DMA:
- Use atomic XA allocation in RCU read section (Christophe JAILLET)
ASPM:
- Collect bits of ASPM-related code that we need even without
CONFIG_PCIEASPM into aspm.c (David E. Box)
- Save/restore L1 PM Substates config for suspend/resume (David E.
Box)
- Update save_save when ASPM config is changed, so a .slot_reset()
during error recovery restores the changed config, not the
.probe()-time config (Vidya Sagar)
Endpoint framework:
- Refactor and improve pci_epf_alloc_space() API (Niklas Cassel)
- Clean up endpoint BAR descriptions (Niklas Cassel)
- Fix ntb_register_device() name leak in error path (Yang Yingliang)
- Return actual error code for pci_vntb_probe() failure (Yang
Yingliang)
Broadcom STB PCIe controller driver:
- Fix MDIO write polling, which previously never waited for
completion (Jonathan Bell)
Cadence PCIe endpoint driver:
- Clear the ARI "Next Function Number" of last function (Jasko-EXT
Wojciech)
Freescale i.MX6 PCIe controller driver:
- Simplify by replacing switch statements with function pointers for
different hardware variants (Frank Li)

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
Documentation:
- improve the character device kerneldocs in user-space headers
- add proper documentation for the character device uAPI (both v1 and v2)
- move the sysfs and gpio-mockup docs into the "obsolete" section
- improve naming consistency for GPIO terms
- clarify the line values description for sysfs
- minor docs improvements
- improve the driver API contract for setting GPIO direction
- mark unsafe APIs as deprecated in kerneldocs and suggest replacements
Other:
- remove an obsolete test from selftests

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

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.

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".

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.

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.

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.

Documentation: leds: Update led-trigger-tty ABI description
The 'led-trigger-tty' uses the same naming in the ABI documentation as
the 'led-trigger-netdev'. Which leads to the following warning when
building the documentation.
Warning: /sys/class/leds/<led>/rx is defined 2 times:
Documentation/ABI/testing/sysfs-class-led-trigger-tty:7
Documentation/ABI/testing/sysfs-class-led-trigger-netdev:49
Warning: /sys/class/leds/<led>/tx is defined 2 times:
Documentation/ABI/testing/sysfs-class-led-trigger-tty:15
Documentation/ABI/testing/sysfs-class-led-trigger-netdev:34
Renaming the 'What' path by prefixing it with 'tty_' solves this problem.

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.

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.

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.

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.

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. |

coresight-tpdm: Add pattern registers support for CMB
Timestamps are requested if the monitor’s CMB data set unit input data matches the value in the Monitor CMB timestamp pattern and mask registers (M_CMB_TPR and M_CMB_TPMR) when CMB timestamp enabled via the timestamp insertion enable register bit(CMB_TIER.PATT_TSENAB). The pattern match trigger output is achieved via setting values into the CMB trigger pattern and mask registers (CMB_XPR and CMB_XPMR). 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 the corresponding pattern register.

hwmon: add fault attribute for voltage channels
Sometimes a voltage channel might have an hard failure (eg: a shorted MOSFET). Hence, add a fault attribute to report such failures.

crypto: qat - add auto reset on error
Expose the `auto_reset` sysfs attribute to configure the driver to reset the device when a fatal error is detected. When auto reset is enabled, the driver resets the device when it detects either an heartbeat failure or a fatal error through an interrupt. This patch is based on earlier work done by Shashank Gupta.

crypto: qat - add heartbeat error simulator
Add a mechanism that allows to inject a heartbeat error for testing purposes. A new attribute `inject_error` is added to debugfs for each QAT device. Upon a write on this attribute, the driver will inject an error on the device which can then be detected by the heartbeat feature. Errors are breaking the device functionality thus they require a device reset in order to be recovered. This functionality is not compiled by default, to enable it CRYPTO_DEV_QAT_ERROR_INJECTION must be set.

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.

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.

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.

VFIO updates for v6.8-rc1
- 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)
- Migration fixes for the hisi-acc-vfio-pci variant driver.
(Shameer Kolothum)
- Kconfig dependency fix for new virtio-vfio-pci variant driver.

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.

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.
