Pull power management updates from Rafael Wysocki:
"From the functional perspective, the most significant change here is
the addition of support for Energy Models that can be updated
dynamically at run time.
There is also the addition of LZ4 compression support for hibernation,
the new preferred core support in amd-pstate, new platforms support in
the Intel RAPL driver, new model-specific EPP handling in intel_pstate

suspend statistics code undergoes a significant rework and there is a
usual bunch of fixes and code cleanups all over.

There exist card implementations with a CDAT table using a fixed size
buffer, but with entries filled in that do not fill the whole table
length size. Then, the last entry in the CDAT table may not mark the
end of the CDAT table buffer specified by the length field in the CDAT
header. It can be shorter with trailing unused (zero'ed) data. The
actual table length is determined while reading all CDAT entries of
the table with DOE.
If the table is greater than expected (containing zero'ed trailing
data), the CDAT parser fails with:
[ 48.691717] Malformed DSMAS table length: (24:0)
[ 48.702084] [CDAT:0x00] Invalid zero length
[ 48.711460] cxl_port endpoint1: Failed to parse CDAT: -22
In addition, a check of the table buffer length is missing to prevent
an out-of-bound access then parsing the CDAT table.
Hardening code against device returning borked table. Fix that by
providing an optional buffer length argument to
acpi_parse_entries_array() that can be used by cdat_table_parse() to
propagate the buffer size down to its users to check the buffer
length. This also prevents a possible out-of-bound access mentioned.
Add a check to warn about a malformed CDAT table length.

Move CXL protocol error types from einj.c (now einj-core.c) to einj-cxl.c.
einj-cxl.c implements the necessary handling for CXL protocol error
injection and exposes an API for the CXL core to use said functionality,
while also allowing the EINJ module to be built without CXL support.
Because CXL error types targeting CXL 1.0/1.1 ports require special
handling, only allow them to be injected through the new cxl debugfs
interface (next commit) and return an error when attempting to inject
through the legacy interface.

Change the EINJ module to install a platform device/driver on module
init and move the module init() and exit() functions to driver probe and
remove. This change allows the EINJ module to load regardless of whether
setting up EINJ succeeds, which allows dependent modules to still load
(i.e. the CXL core).
Since EINJ may no longer be initialized when the module loads, any
functions that are called from dependent/external modules should
safegaurd against the case EINJ didn't load.

For the numa nodes that are not created by SRAT, no memory_target is
allocated and is not managed by the HMAT_REPORTING code. Therefore
hmat_callback() memory hotplug notifier will exit early on those NUMA
nodes. The CXL memory hotplug notifier will need to call
node_set_perf_attrs() directly in order to setup the access sysfs
attributes.
In acpi_numa_init(), the last proximity domain (pxm) id created by SRAT is
stored. Add a helper function acpi_node_backed_by_real_pxm() in order to
check if a NUMA node id is defined by SRAT or created by CFMWS.
node_set_perf_attrs() symbol is exported to allow update of perf attribs
for a node. The sysfs path of
/sys/devices/system/node/nodeX/access0/initiators/* is created by
node_set_perf_attrs() for the various attributes where nodeX is matched
to the NUMA node of the CXL region.

When the CXL region is formed, the driver computes the performance data
for the region. However this data is not available at the node data
collection that has been populated by the HMAT during kernel
initialization. Add a memory hotplug notifier to update the access
coordinates to the 'struct memory_target' context kept by the
HMAT_REPORTING code.
Add CXL_CALLBACK_PRI for a memory hotplug callback priority. Set the
priority number to be called before HMAT_CALLBACK_PRI. The CXL update must
happen before hmat_callback().
A new HMAT_REPORTING helper hmat_update_target_coordinates() is added in
order to allow CXL to update the memory_target access coordinates.
A new ext_updated member is added to the memory_target to indicate that
the access coordinates within the memory_target has been updated by an
external agent such as CXL. This prevents data being overwritten by the
hmat_update_target_attrs() triggered by hmat_callback().

For generic targets, there's no reason to call
register_memory_node_under_compute_node() with the access levels that are
only visible to HMAT handling code. Only update the attributes and rename
hmat_register_generic_target_initiators() to hmat_update_generic_target().
The original call path ends up triggering register_memory_node_under_compute_node().
Although the access level would be "3" and not impact any current node arrays, it
introduces unwanted data into the numa node access_coordinate array.

This reverts commit d52848620d, which was
originally put in place to work around a s2idle failure on this platform
where the NVMe device was inaccessible upon resume.
After extended testing, we found that the firmware's implementation of S3
is buggy and intermittently fails to wake up the system. We need to revert
to s2idle mode.
The NVMe issue has now been solved more precisely in the commit titled
"PCI: Disable D3cold on Asus B1400 PCI-NVMe bridge"

To support GHES_ASSIST on Machine Check Architecture (MCA) error sources,
a set of GHES structures is provided by the system firmware for each MCA
error source. Each of these sets consists of a GHES structure for each MCA
bank on each logical CPU, with all structures of a set sharing a common
Related Source ID, equal to the Source ID of one of the MCA error source
structures.[1] On SOCs with large core counts, this typically equates to
tens of thousands of GHES_ASSIST structures for MCA under
"/sys/bus/platform/drivers/GHES".
Support for GHES_ASSIST however, hasn't been implemented in the kernel. As
such, the information provided through these structures is not consumed by
Linux. Moreover, these GHES_ASSIST structures for MCA, which are supposed
to provide supplemental information in context of an error reported by
hardware, are setup as independent error sources by the kernel during HEST
initialization.
Additionally, if the Type field of the Notification structure, associated
with these GHES_ASSIST structures for MCA, is set to Polled, the kernel
sets up a timer for each individual structure. The duration of the timer
is derived from the Poll Interval field of the Notification structure. On
SOCs with high core counts, this will result in tens of thousands of
timers expiring periodically causing unnecessary preemptions and wastage
of CPU cycles. The problem will particularly intensify if Poll Interval
duration is not sufficiently high.
Since GHES_ASSIST support is not present in kernel, skip initialization
of GHES_ASSIST structures for MCA to eliminate their performance impact.

Revert "ACPI: EC: Use a spin lock without disabing interrupts"
There is no particular reason why device object subtree rescans in
acpi_scan_device_check() and acpi_scan_device_check() should be carried
out differently, so move the rescan code into a new function called
acpi_scan_rescan_bus() and make both the functions above invoke it.
While at it, in the Device Check case, start the device object subtree
rescan mentioned above from the target device's parent, as per the
specification. [1]

The underlying problem is the handling of the enabled bit in device
status (bit 1 of _STA return value) which is required by the ACPI
specification to be observed in addition to the present bit (bit 0
of _STA return value) [1], but Linux does not observe it.
Since Linux has not looked at that bit for a long time, it is generally
risky to start obseving it in all device enumeration cases, especially
at the system initialization time, but it can be observed when the
kernel receives a Bus Check or Device Check notification indicating a
change in device configuration. In those cases, seeing the enabled bit
clear may be regarded as an indication that the device at hand should
not be used any more.
For this reason, rework the handling of Device Check and Bus Check
notifications in the ACPI core device enumeration code in the
following way:
1. Rename acpi_bus_trim_one() to acpi_scan_check_and_detach() and make
it check device status if its second argument is not NULL, in which
case it will detach scan handlers or ACPI drivers from devices whose
_STA returns the enabled bit clear.
2. Make acpi_scan_device_check() and acpi_scan_bus_check() invoke
acpi_scan_check_and_detach() with a non-NULL second argument
unconditionally, so scan handlers and ACPI drivers are detached
from the target device and its ancestors if their _STA returns the
enabled bit clear.

It is generally invalid to fail a Device Check notification if the scan
handler has not been attached to the given device after a bus rescan,
because there may be valid reasons for the scan handler to refuse
attaching to the device (for example, the device is not ready).
For this reason, modify acpi_scan_device_check() to return 0 in that
case without printing a warning.
While at it, reduce the log level of the "already enumerated" message
in the same function, because it is only interesting when debugging
notification handling

.remove_new(), which already returns void. Eventually after all drivers

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to

Instead of returning an error code, emit a better error message than the
core. Apart from the improved error message this patch has no effects
for the driver.

Because the thermal core creates and uses its own copy of the trips
table passed to thermal_zone_device_register_with_trips(), it is not
necessary to hold on to a local copy of it any more after the given
thermal zone has been registered.
Accordingly, modify the ACPI thermal driver to store the trips table
passed to thermal_zone_device_register_with_trips() in a local variable
which is automatically discarded when acpi_thermal_add() returns to
its caller.
Also make some additional code simplifications unlocked by the above

The ACPI custom_method debugfs interface is security-sensitive and
concurrent access to it is broken [1].
Moreover, the recipe for preparing a customized version of a given
control method has changed at one point due to ACPICA changes, which
has not been reflected in its documentation, so whoever used it before
has had to adapt and it had gone unnoticed for a long time.
This interface was a bad idea to start with and its implementation is
fragile at the design level. It's been always conceptually questionable,
problematic from the security standpoint and implemented poorly.
Patches fixing its most apparent functional issues (for example, [2]) don't
actually address much of the above.
Granted, at the time it was introduced, there was no alternative, but
there is the AML debugger in the kernel now and there is the configfs
interface allowing custom ACPI tables to be loaded. The former can be
used for extensive AML debugging and the latter can be use for testing
new AML. [3]
Accordingly, drop custom_method along with its (outdated anyway)
documentation.

Some recent(ish) Dell AIO devices have a backlight controller board
connected to an UART.
This UART has a DELL0501 HID with CID set to PNP0501 so that the UART is
still handled by 8250_pnp.c. Unfortunately there is no separate ACPI device
with an UartSerialBusV2() resource to model the backlight-controller.
This causes the kernel to create a /dev/ttyS0 char-device for the UART
instead of creating an in kernel serdev-controller + serdev-device pair
for a kernel backlight driver.
Use the existing acpi_quirk_skip_serdev_enumeration() mechanism to work
around this by returning skip=true for tty-ctrl parents with a HID
of DELL0501.
Like other cases where the UartSerialBusV2() resource is missing or broken
this will only create the serdev-controller device and the serdev-device
itself will need to be instantiated by platform code.
Unfortunately in this case there is no device for the platform-code
instantiating the serdev-device to bind to. So also create
a platform_device for this.

Commit eb9299bead ("ACPI: EC: Use a spin lock without disabing

behavior, which is a significant CPU load increase when the EC

This most likely happens due to increased spinlock contention
and so reducing this effect would require a major rework of the
EC driver locking. There is no time for this in the current
cycle, so revert commit eb9299bead.

Initial tests with the CXL CPER implementation identified that error
reports were being duplicated in the log and the trace event [1]. Then
it was discovered that the notification handler took sleeping locks
while the GHES event handling runs in spin_lock_irqsave() context [2]
While the duplicate reporting was fixed in v6.8-rc4, the fix for the
sleeping-lock-vs-atomic collision would enjoy more time to settle and
gain some test cycles. Given how late it is in the development cycle,
remove the CXL hookup for now and try again during the next merge
window.
Note that end result is that v6.8 does not emit CXL CPER payloads to the
kernel log, but this is in line with the CXL trend to move error
reporting to trace events instead of the kernel log.

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.
Add INTC10CF, the HID of IVSC MEI bus ACPI device on MTL platform,
to acpi_honor_dep_ids.

"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

Pull driver core updates from Greg KH:
"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

Merge tag 'thermal-6.8-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull thermal control updates from Rafael Wysocki:
"These add support for the D1/T113s THS controller to the sun8i driver
and a DT-based mechanism for platforms to indicate a preference to
reboot (instead of shutting down) on crossing a critical trip point,
fix issues, make other improvements (in the IPA governor, the Intel
HFI driver, the exynos driver and the thermal netlink interface among
other places) and clean up code.
One long-standing issue addressed here is that trip point crossing
notifications sent to user space might be unreliable due to the
incorrect handling of trip point hysteresis in the thermal core:
multiple notifications might be sent for the same event or there might
be events without any notification at all.

times or not at all in some cases (Rafael J. Wysocki)

Pull ACPI updates from Rafael Wysocki:
"From the new features standpoint, the most significant change here is
the addition of CSI-2 and MIPI DisCo for Imaging support to the ACPI
device enumeration code that will allow MIPI cameras to be enumerated
through the platform firmware on systems using ACPI.
Also significant is the switch-over to threaded interrupt handlers for
the ACPI SCI and the dedicated EC interrupt (on systems where the
former is not used) which essentially allows all ACPI code to run with
local interrupts enabled. That should improve responsiveness
significantly on systems where multiple GPEs are enabled and the
handling of one SCI involves many I/O address space accesses which
previously had to be carried out in one go with disabled interrupts on
the local CPU.
Apart from the above, the ACPI thermal zone driver will use the
Thermal fast Sampling Period (_TFP) object if available, which should
allow temperature changes to be followed more accurately on some
systems, the ACPI Notify () handlers can run on all CPUs (not just on
CPU0), which should generally speed up the processing of events
signaled through the ACPI SCI, and the ACPI power button driver will
trigger wakeup key events via the input subsystem (on systems where it
is a system wakeup device)
In addition to that, there are the usual bunch of fixes and cleanups.
Specifics:
- Add CSI-2 and DisCo for Imaging support to the ACPI device
enumeration code (Sakari Ailus, Rafael J. Wysocki)
- Adjust the cpufreq thermal reduction algorithm in the ACPI
processor driver for Tegra241 (Srikar Srimath Tirumala, Arnd
Bergmann)

BIOS can configure memory devices as firmware first. This will send CXL
events to the firmware instead of the OS. The firmware can then send
these events to the OS via UEFI.
UEFI v2.10 section N.2.14 defines a Common Platform Error Record (CPER)
format for CXL Component Events. The format is mostly the same as the
CXL Common Event Record Format. The difference is the use of a GUID in
the Section Type rather than a UUID as part of the event itself.
Add GHES support to detect CXL CPER records and call a registered
callback with the event.
A notifier chain was considered for the callback but the complexity did
not justify the use case as only the CXL subsystem requires this event.
Enforce that only one callback can be registered at any time.

Asus Vivobook E1504GA and E1504GAB notebooks are affected by bug #216158
(DSDT specifies the kbd IRQ as level active-low and using the override
changes this to rising edge, stopping the keyboard from working).
Users of these notebooks do not have a working keyboard unless they add
their DMI information to the struct irq1_level_low_skip_override array
and compile a custom kernel.
Add support for these computers to the Linux kernel without requiring
the end-user to recompile the kernel.

Modify the interface to use struct cppc_perf_caps *caps instead of

cppc_cpufreq was converting the lowest and nominal freq from MHz to kHz

Dan Williams suggested changing the struct 'node_hmem_attrs' to
'access_coordinates' [1]. The struct is a container of r/w-latency and
r/w-bandwidth numbers. Moving forward, this container will also be used by
CXL to store the performance characteristics of each link hop in
the PCIE/CXL topology. So, where node_hmem_attrs is just the access
parameters of a memory-node, access_coordinates applies more broadly
to hardware topology characteristics. The observation is that seemed like
an exercise in having the application identify "where" it falls on a
spectrum of bandwidth and latency needs. For the tuple of
read/write-latency and read/write-bandwidth, "coordinates" is not a perfect
fit. Sometimes it is just conveying values in isolation and not a
"location" relative to other performance points, but in the end this data
is used to identify the performance operation point of a given memory-node.

The CDAT table is very similar to ACPI tables when it comes to sub-table
and entry structures. The helper functions can be also used to parse the
CDAT table. Add support to the helper functions to deal with an external
CDAT table, and also handle the endieness since CDAT can be processed by a
BE host. Export a function cdat_table_parse() for CXL driver to parse
a CDAT table.
In order to minimize ACPICA code changes, __force is being utilized to deal
with the case of a big endian (BE) host parsing a CDAT. All CDAT data
structure variables are being force casted to __leX as appropriate.

There are two major types of uncorrected recoverable (UCR) errors :
- Synchronous error: The error is detected and raised at the point of
the consumption in the execution flow, e.g. when a CPU tries to
access a poisoned cache line. The CPU will take a synchronous error
exception such as Synchronous External Abort (SEA) on Arm64 and
Machine Check Exception (MCE) on X86. OS requires to take action (for
example, offline failure page/kill failure thread) to recover this
uncorrectable error.
- Asynchronous error: The error is detected out of processor execution
context, e.g. when an error is detected by a background scrubber.
Some data in the memory are corrupted. But the data have not been
consumed. OS is optional to take action to recover this uncorrectable
error.
When APEI firmware first is enabled, a platform may describe one error
source for the handling of synchronous errors (e.g. MCE or SEA notification
), or for handling asynchronous errors (e.g. SCI or External Interrupt
notification). In other words, we can distinguish synchronous errors by
APEI notification. For synchronous errors, kernel will kill the current
process which accessing the poisoned page by sending SIGBUS with
BUS_MCEERR_AR. In addition, for asynchronous errors, kernel will notify the
process who owns the poisoned page by sending SIGBUS with BUS_MCEERR_AO in
early kill mode. However, the GHES driver always sets mf_flags to 0 so that
all synchronous errors are handled as asynchronous errors in memory failure.
To this end, set memory failure flags as MF_ACTION_REQUIRED on synchronous
events.

Notify () handlers, like GPE handlers, are only allowed to run on CPU0
now out of the concern that they might trigger an SMM trap leading to
memory corruption. Namely, in some cases, SMM code might corrupt memory
if not run on CPU0.
However, Notify () handlers are registered by kernel code and they
are not likely to evaluate AML that would trigger an SMM trap. In
fact, many of them don't even evaluate any AML at all and even if
they do, that AML may as well be evaluated in other code paths. In
other words, they are not special from the AML evaluation perspective,
so there is no real reason to treat them in any special way.
Accordingly, allow Notify () handlers, unlike GPE handlers, to be
executed by all CPUs in the system.
Also adjust the allocation of the "notify" workqueue to allow multiple
handlers to be executed at the same time, because they need not be
serialized.

which is backed by a firmware interface to turn CPUs on and off.
acpi_processor_hotadd_init() and acpi_processor_remove() are for adding
and removing CPUs that were not present at boot. arm64 systems that do this
are not supported as there is currently insufficient information in the
platform description. (e.g. did the GICR get removed too?)
arm64 currently relies on the MADT enabled flag check in map_gicc_mpidr()
to prevent CPUs that were not described as present at boot from being
added to the system. Similarly, riscv relies on the same check in
map_rintc_hartid(). Both architectures also rely on the weak 'always fails'
definitions of acpi_map_cpu() and arch_register_cpu().
Subsequent changes will redefine ACPI_HOTPLUG_CPU as making possible
CPUs present. Neither arm64 nor riscv support this.
Disable ACPI_HOTPLUG_CPU for arm64 and riscv by removing 'default y' and
selecting it on the other three ACPI architectures. This allows the weak
definitions of some symbols to be removed.

ACPI: video: Use acpi_video_device for cooling-dev driver data
ACPI: Fix ARM32 platforms compile issue introduced by fw_table changes
In the current arrangement, all of the acpi_ev_sci_xrupt_handler() code
is run as an interrupt handler for the SCI, in interrupt context. Among
other things, this causes it to run with local interrupts off which
can be problematic if many GPEs are enabled and they are located in the
I/O address space, for example (because in that case local interrupts
will be off for the duration of all of the GPE hardware accesses carried
out while handling an SCI combined and that may be quite a bit of time
in extreme scenarios).
However, there is no particular reason why the code in question really
needs to run in interrupt context and in particular, it has no specific
reason to run with local interrupts off. The only real requirement is
to prevent multiple instences of it from running in parallel with each
other, but that can be achieved regardless.
For this reason, use request_threaded_irq() instead of request_irq() for
the ACPI SCI and pass IRQF_ONESHOT to it in flags to indicate that the
interrupt needs to be masked while its handling thread is running so as
to prevent it from re-triggering while it is being handled (and in
particular until the final handled/not handled outcome is determined).
While at it, drop a redundant local variable from acpi_irq().

The acpi_video code was storing the acpi_video_device as driver_data
in the acpi_device children of the acpi_video_bus acpi_device.
But the acpi_video driver only binds to the bus acpi_device.
It uses, but does not bind to, the children. Since it is not
the driver it should not be using the driver_data of the children's
acpi_device-s.
Since commit 0d16710146 ("ACPI: bus: Set driver_data to NULL every
time .add() fails") the childen's driver_data ends up getting set
to NULL after a driver fails to bind to the children leading to a NULL
pointer deref in video_get_max_state when registering the cooling-dev:

It turns out there are more subtle races beyond just the main part of
__iommu_probe_device() itself running in parallel - the dev_iommu_free()

Vendor-Defined Error types are supported by the platform apart from
standard error types if bit 31 is set in the output of GET_ERROR_TYPE
Error Injection Action.[1] While the errors themselves and the length
of their associated "OEM Defined data structure" might vary between
vendors, the physical address of this structure can be computed through
vendor_extension and length fields of "SET_ERROR_TYPE_WITH_ADDRESS" and
"Vendor Error Type Extension" Structures respectively.[2][3]
Currently, however, the einj module only computes the physical address of
Vendor Error Type Extension Structure. Neither does it compute the physical
address of OEM Defined structure nor does it establish the memory mapping
required for injecting Vendor-defined errors. Consequently, userspace
tools have to establish the very mapping through /dev/mem, nopat kernel
parameter and system calls like mmap/munmap initially before injecting
Vendor-defined errors.
Circumvent the issue by computing the physical address of OEM Defined data
structure and establishing the required mapping with the structure. Create
a new file "oem_error", if the system supports Vendor-defined errors, to
export this mapping, through debugfs_create_blob(). Userspace tools can
then populate their respective OEM Defined structure instances and just
write to the file as part of injecting Vendor-defined Errors. Similarly,
the tools can also read from the file if the system firmware provides some
information through the OEM defined structure after error injection.

OSPM can discover the error injection capabilities of the platform by
executing GET_ERROR_TYPE error injection action.[1] The action returns
a DWORD representing a bitmap of platform supported error injections.[2]
The available_error_type_show() function determines the bits set within
this DWORD and provides a verbose output, from einj_error_type_string
array, through /sys/kernel/debug/apei/einj/available_error_type file.
The function however, assumes one to one correspondence between an error's
position in the bitmap and its array entry offset. Consequently, some
errors like Vendor Defined Error Type fail this assumption and will
incorrectly be shown as not supported, even if their corresponding bit is
set in the bitmap and they have an entry in the array.
Navigate around the issue by converting einj_error_type_string into an
array of structures with a predetermined mask for all error types
corresponding to their bit position in the DWORD returned by GET_ERROR_TYPE
action. The same breaks the aforementioned assumption resulting in all
supported error types by a platform being outputted through the above
available_error_type file.

Modify the ACPI thermal driver to use functions from the ACPI thermal
library to obtain trip point temperature values instead of duplicating
them locally.
Among other things, this requires the functions in question to be
exported to it, because it can be built as a module.
It effectively changes the behavior of the driver to treat temperature
values out of the reasonable range (-55 centigrade to 175 centigrade) as
invalid, but there is no other expected functional impact.
Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
Because the ACPI thermal driver generally operates temperature values
in deci-Kelvin, it needs the library functions returning temperature
for various trip point types to use deci-Kelvin too.
To address that, arrange the ACPI thermal library code in three levels
of functions where the high-level ones will return temperature in
milli-Celsius, as needed by the thermal core and the majority of
thermal drivers, the mid-level ones will return temperature in
deci-Kelvin and will be called internally by the corresponding high-
level functions, and all of the mid-level functions will call the same
low-level one, acpi_trip_temp(), to actually evaluate ACPI objects to
retrieve themperature values from the platform firmware.
Going forward, this will allow the ACPI thermal driver to use the
mid-level functions to provide temperature values needed by it, so as
to reduce code duplication related to evaluating trip temperature ACPI
control methods.
No intentional functional impact.

The ACPI thermal library contains functions that can be used to
retrieve trip point temperature values through the platform firmware
for various types of trip points. Each of these functions basically
evaluates a specific ACPI object, checks if the value produced by it
is reasonable and returns it (or THERMAL_TEMP_INVALID if anything
fails).
It made sense to hold it in drivers/thermal/ so long as it was only used
by the code in that directory, but since it is also going to be used by
the ACPI thermal driver located in drivers/acpi/, move it to the latter
in order to keep the code related to evaluating ACPI objects defined in
the specification proper together.
No intentional functional impact.

The platform can deny certain tunneling from the OS and it does that by
clearing the control bits it does not want the OS to get and returning
with OSC_CAPABILITIES_MASK_ERROR bit set. Currently we do not handle
this properly so if this happens, for example when the platform denies
PCIe tunneling, we just fail the whole negotiation and revert back to
what the Thunderbolt driver is doing to figure out whether the
controller is running firmware connection manager or not. However, we
should honor what the platform returns.
For this reason run the USB4 _OSC() first with query bit set, and then
use the returned control double word (that may contain some of the bits
cleared by the platform) and run it second time with query bit clear.
While there, remove an extra space from the assignment of the control
double word.

Since commit 3dbc80a3e4 ("ACPI: video: Make backlight class device
registration a separate step (v2)") acpi_video# backlights are no longer
automatically registered. Instead they now only get registered when
the GPU/KMS driver calls acpi_video_register_backlight() which it only
does when it has detected an internal LCD panel.
This fixes the issue of sometimes a non-working acpi_video# backlight
showing up on Desktops / HDMI-sticks without an internal LCD display
in a more complete and robust manner then the LCD flag check which
gets enabled by the should_check_lcd_flag() helper does.
Therefor the should_check_lcd_flag() helper is no longer necessary.
The lcd_only flag itself is still necessary to only register
a single backlight device (for the right output) on the ESPRIMO Mobile
M9410 which has 2 ACPI video connector nodes with a _BCM control method,
which is the issue for which the flag was originally introduced in

This unnecessarily touches the power-state of the GPU itself, while
the issue it tries to address only requires calling _PS0 on the child

Touching the power-state of the GPU itself is causing suspend / resume

Instead use acpi_device_fix_up_power_children(), which only touches

Also remove the mechanism allowing data nodes to be referenced
indirectly, with the help of an object reference pointing to the

Note that this change allows also using strings for referencing device

The I2C-core already has filtering to skip i2c_client instantiation for
LNXVIDEO acpi_device-s with I2cSerialBus resources, since LNXVIDEO devices
are not i2c_client-s and are handled by the acpi_video driver.
This filtering was added to i2c-core-acpi.c in commit 3a4991a986 ("i2c:
acpi: Do not create i2c-clients for LNXVIDEO ACPI devices").
Now a similar problem has shown up where the SPI-core is instantiating
an unwanted SPI-device for a SpiSerialBus resource under a LNXVIDEO
acpi_device. On a Lenovo Yoga Tab 3 YT3-X90F this unwanted SPI-device
instanstantiation causes the SPI-device instanstantiation for the WM5102
audio codec to fail with:
[ 21.988441] pxa2xx-spi 8086228E:00: chipselect 0 already in use
Instead of duplicating the I2C-core filtering in the SPI-core code, push
the filtering of SerialBus resources under LNXVIDEO acpi_device-s up into
the ACPI-core by adding the LNXVIDEO HID to ignore_serial_bus_ids[].
Note the filtering in the I2C-core i2c_acpi_do_lookup() function is still
necessary because this not only impacts i2c_client instantiation but it
also makes the I2C-core ignore the I2cSerialBus resource when checking what

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
for CXL QOS support"

* Major refactoring of the CPU capability detection logic resulting in
the removal of the cpus_have_const_cap() function and migrating the
code to "alternative" branches where possible
* Backtrace/kgdb: use IPIs and pseudo-NMI
* Perf and PMU:
- Add support for Ampere SoC PMUs
- Multi-DTC improvements for larger CMN configurations with multiple
Debug & Trace Controllers
- Rework the Arm CoreSight PMU driver to allow separate registration of
vendor backend modules
- Fixes: add missing MODULE_DEVICE_TABLE to the amlogic perf
driver; use device_get_match_data() in the xgene driver; fix NULL
pointer dereference in the hisi driver caused by calling
cpuhp_state_remove_instance(); use-after-free in the hisi driver
* HWCAP updates:
- FEAT_SVE_B16B16 (BFloat16)
- FEAT_LRCPC3 (release consistency model)
- FEAT_LSE128 (128-bit atomic instructions)
* SVE: remove a couple of pseudo registers from the cpufeature code.
There is logic in place already to detect mismatched SVE features
* Miscellaneous:
- Reduce the default swiotlb size (currently 64MB) if no ZONE_DMA
bouncing is needed. The buffer is still required for small kmalloc()
buffers
- Fix module PLT counting with !RANDOMIZE_BASE
- Restrict CPU_BIG_ENDIAN to LLVM IAS 15.x or newer move
synchronisation code out of the set_ptes() loop
- More compact cpufeature displaying enabled cores
- Kselftest updates for the new CPU features

The acpi_thermal_unregister_thermal_zone() is paired with
acpi_thermal_register_thermal_zone() so it should mirror it. It should
clean up all the resources that the register function allocated and
leave the stuff that was allocated elsewhere.
Unfortunately, it doesn't call thermal_zone_device_disable(). Also it
calls kfree(tz->trip_table) when it shouldn't. That was allocated in
acpi_thermal_add(). Putting the kfree() here leads to a double free
in the acpi_thermal_add() clean up function.
Likewise, the acpi_thermal_remove() should mirror acpi_thermal_add() so
it should have an explicit kfree(tz->trip_table) as well.

Some of the routines in ACPI driver/acpi/tables.c can be shared with
parsing CDAT. CDAT is a device-provided data structure that is formatted
similar to a platform provided ACPI table. CDAT is used by CXL and can
exist on platforms that do not use ACPI. Split out the common routine
from ACPI to accommodate platforms that do not support ACPI and move that
to /lib. The common routines can be built outside of ACPI if
FIRMWARE_TABLES is selected.

snprintf() does not return negative values on error.
To know if the buffer was too small, the returned value needs to be
compared with the length of the passed buffer. If it is greater or
equal, the output has been truncated, so add checks for the truncation
to create_pnp_modalias() and create_of_modalias(). Also make them
return -ENOMEM in that case, as they already do that elsewhere.
Moreover, the remaining size of the buffer used by snprintf() needs to
be updated after the first write to avoid out-of-bounds access as
already done correctly in create_pnp_modalias(), but not in
create_of_modalias(), so change the latter accordingly.

The acpi_pad driver uses struct acpi_driver to register itself while it
would be more logically consistent to use struct platform_driver for this
purpose, because the corresponding platform device is present and the
role of struct acpi_device is to amend the other bus types. ACPI devices
are not meant to be used as proper representation of hardware entities,
but to collect information on those hardware entities provided by the
platform firmware.
Use struct platform_driver for registering the acpi_pad driver.

Currently, it returns the return value from irq_create_fwspec_mapping().
However, irq_create_fwspec_mapping() returns 0 for failure. Fix the
issue by returning -EINVAL if irq_create_fwspec_mapping() returns zero.

Currently the ACPI code doesn't bump the reference count of
the firmware node, while OF counter part does. Not that it's
a problem right now, since ACPI doesn't really use the reference
counting for firmware nodes, it still makes sense to make code
robust against any changes done there. For this,
- switch ACPI case to use device_set_node() to be unified with OF
- move reference counting to amba_device_add()
- switch to use firmware nodes instead of OF ones
In the result we will have reference counting done in the same module
for all callers independently on the nature of firmware node behind.

A memory tiering abstract distance calculation algorithm based on ACPI
HMAT is implemented. The basic idea is as follows.
The performance attributes of system default DRAM nodes are recorded as
the base line. Whose abstract distance is MEMTIER_ADISTANCE_DRAM. Then,
the ratio of the abstract distance of a memory node (target) to
MEMTIER_ADISTANCE_DRAM is scaled based on the ratio of the performance
attributes of the node to that of the default DRAM nodes.
The functions to record the read/write latency/bandwidth of the default
DRAM nodes and calculate abstract distance according to read/write
latency/bandwidth ratio will be used by CXL CDAT (Coherent Device
Attribute Table) and other memory device drivers. So, they are put in
memory-tiers.c.

Previously, in hmat_register_target_initiators(), the performance
attributes are calculated and the corresponding sysfs links and files are
created too. Which is called during memory onlining.
But now, to calculate the abstract distance of a memory target before
memory onlining, we need to calculate the performance attributes for a
memory target without creating sysfs links and files.
To do that, hmat_register_target_initiators() is refactored to make it
possible to calculate performance attributes separately.

The AC driver uses struct acpi_driver to register itself while it would
be more logically consistent to use struct platform_driver for this
purpose, because the corresponding platform device is present and the
role of struct acpi_device is to amend the other bus types. ACPI devices
are not meant to be used as proper representation of hardware entities,
but to collect information on those hardware entities provided by the
platform firmware.
Use struct platform_driver for registering the AC driver.

Provide common prototypes for arch_register_cpu() and

necessary for function prototypes to be conditional on preprocessor macros.
Some architectures (e.g. Loongarch) are missing the prototype for this, and
rather than add it to Loongarch's asm/cpu.h, do the job once for everyone.
Since this covers everyone, remove the now unnecessary prototypes in
asm/cpu.h, and therefore remove the 'static' from one of ia64's

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.

device binding and unbinding, acpi_thermal_bind_cooling_device() and
acpi_thermal_unbind_cooling_device(), respectively, so that they use trip
pointers instead of trip indices which is more straightforward and allows
the driver to become independent of the ordering of trips in the thermal
zone structure.
The general functionality is not expected to be changed.

After removing the valid flag from struct acpi_thermal_trip, the trip
temperature value is used in validity checks, so it must be
THERMAL_TEMP_INVALID for the active trip entries in struct acpi_thermal_trips
that are not going to be used (because the corresponding objects are not
present in the ACPI tables, for example).
Accordingly, modify acpi_thermal_get_trip_points() to set the temperature
value to THERMAL_TEMP_INVALID for trip point entries skipped by it after
acpi_thermal_init_trip() has returned 'false' for an active trip.

`strncpy()` is deprecated for use on NUL-terminated destination strings [1].
We know `osi->string` is a NUL-terminated string due to its eventual use
in `acpi_install_interface()` and `acpi_remove_interface()` which expect
a `acpi_string` which has been specifically typedef'd as:
| typedef char *acpi_string; /* Null terminated ASCII string */
... and which also has other string functions used on it like `strlen`.
Furthermore, padding is not needed in this instance either.
Due to the reasoning above a suitable replacement is `strscpy` [2] since
it guarantees NUL-termination on the destination buffer and doesn't
unnecessarily NUL-pad.
While there is unlikely to be a buffer overread (or other related bug)
in this case, we should still favor a more robust and less ambiguous
interface.

ghes_handle_aer() passes AER data to the PCI core for logging and
recovery by calling aer_recover_queue() with a pointer to struct

The problem was that aer_recover_queue() queues the pointer directly
without copying the aer_capability_regs data. The pointer was to
the ghes->estatus buffer, which could be reused before
aer_recover_work_func() reads the data.
To avoid this problem, allocate a new aer_capability_regs structure

buffer into it, pass a pointer to the new struct to
aer_recover_queue(), and free it after aer_recover_work_func() has

The Xiaomi Mi Pad 2 is currently listed under the:
"Models which should use the vendor backlight interface,
because of broken ACPI video backlight control." section.
But this is not 100% correct. The Xiaomi Mi Pad 2 is one of a set of
x86 tablets which shipped with Android as factory OS. These tablets
have a TI LP8557 backlight controller with its PWM input _not_
connected to the PMIC or chipset (LPSS) PWM output.
Instead the backlight can be controlled by configuring the LP8557
for direct control through its brightness I2C register and then
using the lp855x driver.
This setup means that neither i915's native or acpi_video backlight
control works, so a "vendor" quirk is added for these tablets to
disable both the native and acpi_video backlight devices, but these
devices do not use vendor control in the typical meaning of
vendor specific SMBIOS or ACPI calls being used.
This patch is a preparation patch for adding "vendor" quirks
for a couple more such tablet models.

Commit fd49f99c18 ("ACPI: NUMA: Add a node and memblk for each
CFMWS not in SRAT") did not account for the case where the BIOS
only partially describes a CFMWS Window in the SRAT. That means
the omitted address ranges, of a partially described CFMWS Window,
do not get assigned to a NUMA node.
Replace the call to phys_to_target_node() with numa_add_memblks().
Numa_add_memblks() searches an HPA range for existing memblk(s)
and extends those memblk(s) to fill the entire CFMWS Window.
Extending the existing memblks is a simple strategy that reuses
SRAT defined proximity domains from part of a window to fill out
the entire window, based on the knowledge* that all of a CFMWS
window is of a similar performance class.
*Note that this heuristic will evolve when CFMWS Windows present
a wider range of characteristics. The extension of the proximity
domain, implemented here, is likely a step in developing a more
sophisticated performance profile in the future.
There is no change in behavior when the SRAT does not describe
the CFMWS Window at all. In that case, a new NUMA node with a
single memblk covering the entire CFMWS Window is created.

The Itanium architecture is obsolete, and an informal survey [0] reveals
that any residual use of Itanium hardware in production is mostly HP-UX
or OpenVMS based. The use of Linux on Itanium appears to be limited to
enthusiasts that occasionally boot a fresh Linux kernel to see whether
things are still working as intended, and perhaps to churn out some
distro packages that are rarely used in practice.
None of the original companies behind Itanium still produce or support
any hardware or software for the architecture, and it is listed as
'Orphaned' in the MAINTAINERS file, as apparently, none of the engineers
that contributed on behalf of those companies (nor anyone else, for that
matter) have been willing to support or maintain the architecture
upstream or even be responsible for applying the odd fix. The Intel
firmware team removed all IA-64 support from the Tianocore/EDK2
reference implementation of EFI in 2018. (Itanium is the original
architecture for which EFI was developed, and the way Linux supports it
deviates significantly from other architectures.) Some distros, such as
Debian and Gentoo, still maintain [unofficial] ia64 ports, but many have
dropped support years ago.
While the argument is being made [1] that there is a 'for the common
good' angle to being able to build and run existing projects such as the
Grid Community Toolkit [2] on Itanium for interoperability testing, the
fact remains that none of those projects are known to be deployed on
Linux/ia64, and very few people actually have access to such a system in
the first place. Even if there were ways imaginable in which Linux/ia64
could be put to good use today, what matters is whether anyone is
actually doing that, and this does not appear to be the case.
There are no emulators widely available, and so boot testing Itanium is
generally infeasible for ordinary contributors. GCC still supports IA-64
but its compile farm [3] no longer has any IA-64 machines. GLIBC would
like to get rid of IA-64 [4] too because it would permit some overdue
code cleanups. In summary, the benefits to the ecosystem of having IA-64
be part of it are mostly theoretical, whereas the maintenance overhead
of keeping it supported is real.
So let's rip off the band aid, and remove the IA-64 arch code entirely.
This follows the timeline proposed by the Debian/ia64 maintainer [5],
which removes support in a controlled manner, leaving IA-64 in a known
good state in the most recent LTS release. Other projects will follow
once the kernel support is removed.

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.

"This primarily covers some cleanup work on the EFI runtime wrappers,
which are shared between all EFI architectures except Itanium, and
which provide some level of isolation to prevent faults occurring in

Beyond that, there is a fix that did not make it into v6.5, and some

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.

__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.

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.

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.

Rework the ACPI thermal driver's .get_trend() callback function,
thermal_get_trend(), so that it does not call thermal_get_trip_type()
and thermal_get_trip_temp() which are going to be dropped.
This reduces the overhead of the function too, because it will always
carry out a trip point lookup once after the change.

Make the ACPI thermal driver use thermal_zone_device_register_with_trips()
to register its thermal zones.
For this purpose, make it create a trip point table that will be passed to
thermal_zone_device_register_with_trips() as an argument.
Also use the thermal_zone_update_trip_temp() helper introduced
previously to update temperatures of the passive and active trip
points after a trip points change notification from the platform
firmware.

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.

Rename the trips variable in acpi_thermal_register_thermal_zone() to
trip_count so its name better reflects the purpose, rearrange white
space in the loop over active trips for clarity and reduce code
duplication related to calling thermal_zone_device_register() by
using an extra local variable to store the passive delay value.

The processor _OSC method is already used for a workaround introduced

Create a new callback function called acpi_processor_osc() to be invoked

analogy with the already existing acpi_hwp_native_thermal_lvt_osc().

This is a step toward making __iommu_probe_device() self contained.
It should, under proper locking, check if the device is already associated
with an iommu driver and resolve parallel probes. All but one of the
callers open code this test using two different means, but they all
rely on dev->iommu_group.
Currently the bus_iommu_probe()/probe_iommu_group() and
probe_acpi_namespace_devices() rejects already probed devices with an
unlocked read of dev->iommu_group. The OF and ACPI "replay" functions use
device_iommu_mapped() which is the same read without the pointless
refcount.
Move this test into __iommu_probe_device() and put it under the
iommu_probe_device_lock. The store to dev->iommu_group is in
iommu_group_add_device() which is also called under this lock for iommu
driver devices, making it properly locked.
The only path that didn't have this check is the hotplug path triggered by
BUS_NOTIFY_ADD_DEVICE. The only way to get dev->iommu_group assigned
outside the probe path is via iommu_group_add_device(). Today the only
caller is VFIO no-iommu which never associates with an iommu driver. Thus
adding this additional check is safe.

ACPICA commit 90310989a0790032f5a0140741ff09b545af4bc5
According to the ACPI specification 19.6.134, no argument is required to be passed for ASL Timer instruction. For taking care of no argument, AML_NO_OPERAND_RESOLVE flag is added to ASL Timer instruction opcode.
When ASL timer instruction interpreted by ACPI interpreter, getting error. After adding AML_NO_OPERAND_RESOLVE flag to ASL Timer instruction opcode, issue is not observed.

ACPICA commit 3a9dbc5cb1573b87a16b50918977ab9e53e24408
'object' is known to be NULL at this point. There is little value to log
it twice in the error message.

ACPICA commit ef7cf185a046d76119b631f16e7c991543c80edc
This commit add the Interrupt command to acpiexec.
The Interrupt command simulates an interrupt with a int_ID (GSIV)
equal to the first argument of the call.
The acpiexec code simulates the behaviour by OSPM: execute the _EVT
method of the GED device associated with that int_ID.

ACPICA commit dc6fd1d12903015726a8a6f87f63e86141576a68
The GED device is described by a _HID of ACPI0013.
This code traverses the namespace identifying all GED devices.
For each GED device in the namespace we record 1) the Interrupt objects
and the _EVT method.
This information is used when an interrupt is simulate.
