4785aa8028 cpuidle, ACPI: Evaluate LPI arch_flags for broadcast timer
Arm® Functional Fixed Hardware Specification defines LPI states,
which provide an architectural context loss flags field that can
be used to describe the context that might be lost when an LPI
state is entered.

- Core context Lost
        - General purpose registers.
        - Floating point and SIMD registers.
        - System registers, include the System register based
        - generic timer for the core.
        - Debug register in the core power domain.
        - PMU registers in the core power domain.
        - Trace register in the core power domain.
- Trace context loss
- GICR
- GICD

Qualcomm's custom CPUs preserves the architectural state,
including keeping the power domain for local timers active.
when core is power gated, the local timers are sufficient to
wake the core up without needing broadcast timer.

The patch fixes the evaluation of cpuidle arch_flags, and moves only to
broadcast timer if core context lost is defined in ACPI LPI.

f4dcf06bc6 ACPI: video: Fix NULL pointer dereference in acpi_video_bus_add()
acpi_video_bus_add_notify_handler() could free video->input and
set it to NULL on failure, but this failure would be missed in its
caller acpi_video_bus_add(). As a result, when an error happens in
acpi_dev_install_notify_handler(), acpi_video_bus_add() would call
acpi_video_bus_remove_notify_handler(), where a potential NULL pointer
video->input is dereferenced in input_unregister_device().

Fix this by adding a return value check and adjusting the following
error handling code.

b2eb3e67ee ACPI: processor: Fix uninitialized access of buf in acpi_set_pdc_bits()
A bug was introduced during unification of setting CAP_SMP_T_SWCOORD for
the _PDC and _OSC methods.

The third u32 in the buffer is never cleared before setting bits on it.
The memory is not guaranteed to be zero as it was allocated by kmalloc()
instead of kzalloc().

Fix this by initializing the third u32 in the buffer to 0.

ebc7abb35b thermal: Constify the trip argument of the .get_trend() zone callback
Add 'const' to the definition of the 'trip' argument of the
.get_trend() thermal zone callback to indicate that the trip point
passed to it should not be modified by it and adjust the
callback functions implementing it, thermal_get_trend() in the
ACPI thermal driver and __ti_thermal_get_trend(), accordingly.

No intentional functional impact.

8289d810ea thermal: core: Rework .get_trend() thermal zone callback
Passing a struct thermal_trip pointer instead of a trip index to the
.get_trend() thermal zone callback allows one of its 2 implementations,
the thermal_get_trend() function in the ACPI thermal driver, to be
simplified quite a bit, and the other implementation of it in the
ti-soc-thermal driver does not even use the relevant callback argument.

For this reason, change the .get_trend() thermal zone callback
definition and adjust the related code accordingly.

Pull arm64 updates from Will Deacon:
 "I think we have a bit less than usual on the architecture side, but
  that's somewhat balanced out by a large crop of perf/PMU driver
  updates and extensions to our selftests.

  CPU features and system registers:

   - Advertise hinted conditional branch support (FEAT_HBC) to userspace

   - Avoid false positive "SANITY CHECK" warning when xCR registers
     differ outside of the length field

  Documentation:

   - Fix macro name typo in SME documentation

  Entry code:

   - Unmask exceptions earlier on the system call entry path

  Memory management:

   - Don't bother clearing PTE_RDONLY for dirty ptes in pte_wrprotect()
     and pte_modify()

   - Initial support for Coresight TRBE devices on ACPI systems (the
     coresight driver changes will come later)

   - Fix hw_breakpoint single-stepping when called from bpf

   - Fixes for DDR PMU on i.MX8MP SoC

   - Add NUMA-awareness to Hisilicon PCIe PMU driver

   - Add support for recent Arm Cortex CPU PMUs

   - Update Hisilicon PMU maintainers

  Selftests:

   - Add a bunch of new features to the hwcap test (JSCVT, PMULL, AES,
     SHA1, etc)

   - Fix SSVE test to leave streaming-mode after grabbing the signal
     context

   - Add new test for SVE vector-length changes with SME enabled

  Miscellaneous:

   - Allow compiler to warn on suspicious looking system register
     expressions

   - Work around SDEI firmware bug by aborting any running handlers on a
     kernel crash

   - Fix some harmless warnings when building with W=1

5894cf571e acpi/prmt: Use EFI runtime sandbox to invoke PRM handlers
Instead of bypassing the kernel's adaptation layer for performing EFI
runtime calls, wire up ACPI PRM handling into it. This means these calls
can no longer occur concurrently with EFI runtime calls, and will be
made from the EFI runtime workqueue. It also means any page faults
occurring during PRM handling will be identified correctly as
originating in firmware code.

e38abdab44 efi/runtime-wrappers: Remove duplicated macro for service returning void
__efi_call_virt() exists as an alternative for efi_call_virt() for the
sole reason that ResetSystem() returns void, and so we cannot use a call
to it in the RHS of an assignment.

Given that there is only a single user, let's drop the macro, and expand
it into the caller. That way, the remaining macro can be tightened
somewhat in terms of type safety too.

Note that the use of typeof() on the runtime service invocation does not
result in an actual call being made, but it does require a few pointer
types to be fixed up and converted into the proper function pointer
prototypes.

ACPI RTC devices (PNP0B00/PNP0B01/PNP0B02) only. But there are platforms
with SystemCMOS Operetion Region defined under the ACPI Time and Alarm
Device (ACPI000E), which is used by the ACPI pre-defined control methods
like _GRT (Get the Real time) and _SRT (Set the Real time).

When accessing these control methods via the acpi_tad sysfs interface,
missing SystemCMOS address space handler causes errors like below
[  478.255453] ACPI Error: No handler for Region [RTCM] (00000000a8d2dd39) [SystemCMOS] (20230331/evregion-130)
[  478.255458] ACPI Error: Region SystemCMOS (ID=5) has no handler (20230331/exfldio-261)

[  478.255464] No Arguments are initialized for method [_GRT]
[  478.255465] ACPI Error: Aborting method \_SB.AWAC._GRT due to previous error (AE_NOT_EXIST) (20230331/psparse-529)

Export two APIs for SystemCMOS address space handler from acpi_cmos_rtc
scan handler and install the handler for the ACPI Time and Alarm Device
from the ACPI TAD driver.

89c290ea75 ACPI: video: Put ACPI video and its child devices into D0 on boot
Screen brightness can only be changed once on HP ZBook Fury 16 G10.

The vendor reports that the issue is related to the fact that Linux doesn't
invoke _PS0 at boot for all ACPI devices, as expected by the platform firmware:

    Scope (\_SB.PC00.GFX0)
    {
        Scope (DD1F)
        {
            Method (_PS0, 0, Serialized)  // _PS0: Power State 0
            {
                If (CondRefOf (\_SB.PC00.LPCB.EC0.SSBC))
                {
                    \_SB.PC00.LPCB.EC0.SSBC ()
                }
            }
	    ...
	}
	...
    }

The \_SB.PC00.GFX0.DD1F is the panel device, and its _PS0 needs to be
executed at the initialization time to make the brightness control work
properly.

_PS0 is not evaluated for this device, because _PSC is missing,
which violates the ACPI specification (ACPI 6.5, section 7.3.6).

Commit b378549226 ("ACPI / PM: Do not power manage devices in unknown
initial states") tried to work around missing _PSC on platforms with
defective firmware, but got reverted due to a regression.

So the safest approach is to use acpi_device_fix_up_power_extended() to
put ACPI video and its child devices to D0 to address the issue at hand.

With ACPI Spec 6.5 chapter 5.2.12.20, each processor in LoongArch
systems has a Core Programmable Interrupt Controller in MADT. The
value of its type is 0x11 in the spec and defined as enum variable
ACPI_MADT_TYPE_CORE_PIC in the Linux kernel.

Physical IDs can be retrieved from MADT for LoongArch systems during
initialization and they can be retrieved from the _MAT output for
hotplug CPUs.

Add physical CPU ID enumeration for LoongArch systems.

7f6fd06d34 ACPI: scan: Defer enumeration of devices with a _DEP pointing to IVSC device
Inside IVSC, switching ownership requires an interface with two
different hardware modules, ACE and CSI. The software interface
to these modules is based on Intel MEI framework. Usually mei
client devices are dynamically created, so the info of consumers
depending on mei client devices is not present in the firmware
tables.

This causes problems with the probe ordering with respect to
drivers for consumers of these MEI client devices. But on these
camera sensor devices, the ACPI nodes describing the sensors all
have a _DEP dependency on the matching MEI bus ACPI device, so
adding IVSC MEI bus ACPI device to acpi_honor_dep_ids allows
solving the probe-ordering problem by deferring the enumeration of
ACPI-devices which have a _DEP dependency on an IVSC mei bus ACPI
device.

On TGL platform, the HID of IVSC MEI bus ACPI device is INTC1059,
and on ADL platform, the HID is INTC1095. So add both of them to
acpi_honor_dep_ids.

68f4f0378c ACPI: thermal: Carry out trip point updates under zone lock
There is a race condition between acpi_thermal_trips_update() and
acpi_thermal_check_fn(), because the trip points may get updated while
the latter is running which in theory may lead to inconsistent results.
For example, if two trips are updated together, using the temperature
value of one of them from before the update and the temperature value
of the other one from after the update may not lead to the expected
outcome.

Moreover, if thermal_get_trend() runs when a trip points update is in
progress, it may end up using stale trip point temperatures.

To address this, make acpi_thermal_trips_update() call
thermal_zone_device_exec() to carry out the trip points update and
use a new  acpi_thermal_adjust_thermal_zone() wrapper around
__acpi_thermal_trips_update() as the callback function for the latter.

While at it, change the acpi_thermal_trips_update() return data type
to void as that function always returns 0 anyway.

Some HiSilicon SMMU PMCG suffers the erratum 162001900 that the PMU
disable control sometimes fail to disable the counters. This will lead
to error or inaccurate data since before we enable the counters the
counter's still counting for the event used in last perf session.

This patch tries to fix this by hardening the global disable process.
Before disable the PMU, writing an invalid event type (0xffff) to
focibly stop the counters. Correspondingly restore each events on
pmu::pmu_enable().
