Armin Wolf 044a7bfca8 ACPI: EC: Avoid returning AE_OK on errors in address space handler
[ Upstream commit c4bd7f1d78340e63de4d073fd3dbe5391e2996e5 ]

If an error code other than EINVAL, ENODEV or ETIME is returned
by acpi_ec_read() / acpi_ec_write(), then AE_OK is incorrectly
returned by acpi_ec_space_handler().

Fix this by only returning AE_OK on success, and return AE_ERROR
otherwise.

Armin Wolf 284daacf26 ACPI: EC: Abort address space access upon error
[ Upstream commit f6f172dc6a6d7775b2df6adfd1350700e9a847ec ]

When a multi-byte address space access is requested, acpi_ec_read()/
acpi_ec_write() is being called multiple times.

Abort such operations if a single call to acpi_ec_read() /
acpi_ec_write() fails, as the data read from / written to the EC
might be incomplete.

Kuan-Wei Chiu 48ec392991 ACPI: processor_idle: Fix invalid comparison with insertion sort for latency
commit 233323f9b9f828cd7cd5145ad811c1990b692542 upstream.

The acpi_cst_latency_cmp() comparison function currently used for
sorting C-state latencies does not satisfy transitivity, causing
incorrect sorting results.

Specifically, if there are two valid acpi_processor_cx elements A and B
and one invalid element C, it may occur that A < B, A = C, and B = C.
Sorting algorithms assume that if A < B and A = C, then C < B, leading
to incorrect ordering.

Given the small size of the array (<=8), we replace the library sort
function with a simple insertion sort that properly ignores invalid
elements and sorts valid ones based on latency. This change ensures
correct ordering of the C-state latencies.

Mario Limonciello 4d59364add ACPI: x86: Force StorageD3Enable on more products
[ Upstream commit e79a10652bbd320649da705ca1ea0c04351af403 ]

A Rembrandt-based HP thin client is reported to have problems where
the NVME disk isn't present after resume from s2idle.

This is because the NVME disk wasn't put into D3 at suspend, and
that happened because the StorageD3Enable _DSD was missing in the BIOS.

As AMD's architecture requires that the NVME is in D3 for s2idle, adjust
the criteria for force_storage_d3 to match *all* Zen SoCs when the FADT
advertises low power idle support.

This will ensure that any future products with this BIOS deficiency don't
need to be added to the allow list of overrides.

Mario Limonciello 029f2adf93 ACPI: x86: utils: Add Picasso to the list for forcing StorageD3Enable
[ Upstream commit 10b6b4a8ac ]

Picasso was the first APU that introduced s2idle support from AMD,
and it was predating before vendors started to use `StorageD3Enable`
in their firmware.

Windows doesn't have problems with this hardware and NVME so it was
likely on the list of hardcoded CPUs to use this behavior in Windows.

Add it to the list for Linux to avoid NVME resume issues.

Raju Rangoju dc5017c57f ACPICA: Revert "ACPICA: avoid Info: mapping multiple BARs. Your kernel is fine."
[ Upstream commit a83e1385b780d41307433ddbc86e3c528db031f0 ]

Undo the modifications made in commit d410ee5109 ("ACPICA: avoid
"Info: mapping multiple BARs. Your kernel is fine.""). The initial
purpose of this commit was to stop memory mappings for operation
regions from overlapping page boundaries, as it can trigger warnings
if different page attributes are present.

However, it was found that when this situation arises, mapping
continues until the boundary's end, but there is still an attempt to
read/write the entire length of the map, leading to a NULL pointer
deference. For example, if a four-byte mapping request is made but
only one byte is mapped because it hits the current page boundary's
end, a four-byte read/write attempt is still made, resulting in a NULL
pointer deference.

Instead, map the entire length, as the ACPI specification does not
mandate that it must be within the same page boundary. It is
permissible for it to be mapped across different regions.

Vanshidhar Konda 890d39f6d9 ACPI: CPPC: Fix access width used for PCC registers
commit f489c948028b69cea235d9c0de1cc10eeb26a172 upstream

commit 2f4a4d63a193 ("ACPI: CPPC: Use access_width over bit_width for system
memory accesses") modified cpc_read()/cpc_write() to use access_width to
read CPC registers.

However, for PCC registers the access width field in the ACPI register
macro specifies the PCC subspace ID.  For non-zero PCC subspace ID it is
incorrectly treated as access width. This causes errors when reading
from PCC registers in the CPPC driver.

For PCC registers, base the size of read/write on the bit width field.
The debug message in cpc_read()/cpc_write() is updated to print relevant
information for the address space type used to read the register.

Instead, use access_width to determine the size and use the offset and
width to shift and mask the bits to read/write out. Make sure to add a
check for system memory since pcc redefines the access_width to
subspace id.

If access_width is not set, then fall back to using bit_width.

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

Shuai Xue 7cb4103166 ACPI: APEI: set memory failure flags as MF_ACTION_REQUIRED on synchronous events
[ Upstream commit a70297d2213253853e95f5b49651f924990c6d3b ]

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.

Here the first record has zero length.

FBPT subtable:

7F20FE80: 00 00 00 00 00 00 00 00-00 00 00 00 00 00 00 00  *................*

And here FBPT table has FBPT signature repeated instead of the first
record.

Current code will be looping indefinitely due to zero length records, so
break out of the loop if record length is zero.

While we are here, add proper handling for fpdt_process_subtable()
failures.

commit 0da9eccde3270b832c059ad618bf66e510c75d33 upstream.

The TongFang GMxXGxx/TUXEDO Stellaris/Pollaris Gen5 needs IRQ overriding
for the keyboard to work.

Adding an entry for this laptop to the override_table makes the internal
keyboard functional.

Christophe JAILLET 6b413d52f6 ACPI: sysfs: Fix create_pnp_modalias() and create_of_modalias()
[ Upstream commit 48cf49d31994ff97b33c4044e618560ec84d35fb ]

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.

commit 0c21a18d5d upstream.

acpi_register_gsi() should return a negative value in case of failure.

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.

Hans de Goede 763167003a ACPI: resource: Skip IRQ override on ASUS ExpertBook B1402CBA
commit c1ed72171e upstream.

Like various other ASUS ExpertBook-s, the ASUS ExpertBook B1402CBA
has an ACPI DSDT table that describes IRQ 1 as ActiveLow while
the kernel overrides it to EdgeHigh.

This prevents the keyboard from working. To fix this issue, add this laptop
to the skip_override_table so that the kernel does not override IRQ 1.

Yicong Yang f9a2c79c29 perf/smmuv3: Enable HiSilicon Erratum 162001900 quirk for HIP08/09
[ Upstream commit 0242737dc4 ]

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().

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.
