ACPI: NFIT: Fix incorrect calculation of idt size

2023-10-06T11:16:24+00:00

commit 33908660e814203e996f6e775d033c5c32fcf9a7 upstream.

acpi_nfit_interleave's field 'line_offset' is switched to flexible array [1],
but sizeof_idt() still calculates the size in the form of 1-element array.

Therefore, fix incorrect calculation in sizeof_idt().

ACPI: x86: s2idle: Catch multiple ACPI_TYPE_PACKAGE objects

2023-09-23T09:14:19+00:00

[ Upstream commit 883cf0d4cf288313b71146ddebdf5d647b76c78b ]

If a badly constructed firmware includes multiple `ACPI_TYPE_PACKAGE`
objects while evaluating the AMD LPS0 _DSM, there will be a memory
leak.  Explicitly guard against this.

ACPI: video: Add backlight=native DMI quirk for Apple iMac12,1 and iMac12,2

2023-09-23T09:14:18+00:00

[ Upstream commit 8cf04bb321f036dd2e523e993897e0789bd5265c ]

Linux defaults to picking the non-working ACPI video backlight interface
on the Apple iMac12,1 and iMac12,2.

Add a DMI quirk to pick the working native radeon_bl0 interface instead.

perf/smmuv3: Enable HiSilicon Erratum 162001900 quirk for HIP08/09

2023-09-23T09:14:18+00:00

[ Upstream commit 0242737dc4eb9f6e9a5ea594b3f93efa0b12f28d ]

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().

ACPI: video: Add backlight=native DMI quirk for Lenovo Ideapad Z470

2023-09-23T09:14:18+00:00

[ Upstream commit 96b709be183c56293933ef45b8b75f8af268c6de ]

The Lenovo Ideapad Z470 predates Windows 8, so it defaults to using
acpi_video for backlight control. But this is not functional on this
model.

Add a DMI quirk to use the native backlight interface which works.

ACPICA: Add AML_NO_OPERAND_RESOLVE flag to Timer

2023-09-23T09:14:17+00:00

[ Upstream commit 3a21ffdbc825e0919db9da0e27ee5ff2cc8a863e ]

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.

ACPI: x86: s2idle: Fix a logic error parsing AMD constraints table

[ Upstream commit 9cc8cd086f05d9a01026c65c98da88561e9c619e ]

The constraints table should be resetting the `list` object
after running through all of `info_obj` iterations.

This adjusts whitespace as well as less code will now be included
with each loop. This fixes a functional problem is fixed where a
badly formed package in the inner loop may have incorrect data.

ACPI: x86: s2idle: Post-increment variables when getting constraints

[ Upstream commit 3c6b1212d20bbbffcad5709ab0f2d5ed9b5859a8 ]

When code uses a pre-increment it makes the reader question "why".
In the constraint fetching code there is no reason for the variables
to be pre-incremented so adjust to post-increment.
No intended functional changes.

ACPI: thermal: Drop nocrt parameter

commit 5f641174a12b8a876a4101201a21ef4675ecc014 upstream.

The `nocrt` module parameter has no code associated with it and does
nothing.  As `crt=-1` has same functionality as what nocrt should be
doing drop `nocrt` and associated documentation.

This should fix a quirk for Gigabyte GA-7ZX that used `nocrt` and
thus didn't function properly.

have "GM6BGEQ" as DMI product-name instead of "Elimina Pro 16 M",
causing the existing DMI quirk to not work on these models.
