ACPI: video: Add backlight=native DMI quirk for Dell Studio 1569

2023-07-27T06:56:47+00:00

[ Upstream commit 23d28cc0444be3f694eb986cd653b6888b78431d ]

The Dell Studio 1569 predates Windows 8, so it defaults to using
acpi_video# for backlight control, but this is non functional on
this model.

Add a DMI quirk to use the native intel_backlight interface which
does work properly.

ACPI: resource: Remove "Zen" specific match and quirks

2023-07-27T06:56:47+00:00

[ Upstream commit a9c4a912b7dc7ff922d4b9261160c001558f9755 ]

commit 9946e39fe8d0 ("ACPI: resource: skip IRQ override on
AMD Zen platforms") attempted to overhaul the override logic so it
didn't apply on X86 AMD Zen systems.  This was intentional so that
systems would prefer DSDT values instead of default MADT value for
IRQ 1 on Ryzen 6000 systems which typically uses ActiveLow for IRQ1.

This turned out to be a bad assumption because several vendors
add Interrupt Source Override but don't fix the DSDT. A pile of
quirks was collecting that proved this wasn't sustaintable.

Furthermore some vendors have used ActiveHigh for IRQ1.
To solve this problem revert the following commits:
* commit 17bb7046e7ce ("ACPI: resource: Do IRQ override on all TongFang
GMxRGxx")
* commit f3cb9b740869 ("ACPI: resource: do IRQ override on Lenovo 14ALC7")
* commit bfcdf58380b1 ("ACPI: resource: do IRQ override on LENOVO IdeaPad")
* commit 7592b79ba4a9 ("ACPI: resource: do IRQ override on XMG Core 15")
* commit 9946e39fe8d0 ("ACPI: resource: skip IRQ override on AMD Zen
platforms")

ACPI: x86: Add ACPI_QUIRK_UART1_SKIP for Lenovo Yoga Book yb1-x90f/l

2023-07-27T06:56:46+00:00

[ Upstream commit f91280f35895d6dcb53f504968fafd1da0b00397 ]

The Lenovo Yoga Book yb1-x90f/l 2-in-1 which ships with Android as
Factory OS has (another) bug in its DSDT where the UART resource for
the BTH0 ACPI device contains "\\_SB.PCIO.URT1" as path to the UART.

Note that is with a letter 'O' instead of the number '0' which is wrong.

This causes Linux to instantiate a standard /dev/ttyS? device for
the UART instead of a /sys/bus/serial device, which in turn causes
bluetooth to not work.

Similar DSDT bugs have been encountered before and to work around those
the acpi_quirk_skip_serdev_enumeration() helper exists.

Previous devices had the broken resource pointing to the first UART, while
the BT HCI was on the second UART, which ACPI_QUIRK_UART1_TTY_UART2_SKIP
deals with. Add a new ACPI_QUIRK_UART1_SKIP quirk for skipping enumeration
of UART1 instead for the Yoga Book case and add this quirk to the
existing DMI quirk table entry for the yb1-x90f/l .

This leaves the UART1 controller unbound allowing the x86-android-tablets
module to manually instantiate a serdev for it fixing bluetooth.

ACPI: x86: Add skip i2c clients quirk for Nextbook Ares 8A

2023-07-27T06:56:46+00:00

[ Upstream commit 69d6b37695c1f2320cfa330e1e1636d50dd5040a ]

The Nextbook Ares 8A is a x86 ACPI tablet which ships with Android x86
as factory OS. Its DSDT contains a bunch of I2C devices which are not
actually there (the Android x86 kernel fork ignores I2C devices described
in the DSDT).

On this specific model this just not cause resource conflicts, one of
the probe() calls for the non existing i2c_clients actually ends up
toggling a GPIO or executing a _PS3 after a failed probe which turns
the tablet off.

Add a ACPI_QUIRK_SKIP_I2C_CLIENTS for the Nextbook Ares 8 to the
acpi_quirk_skip_dmi_ids table to avoid the bogus i2c_clients and
to fix the tablet turning off during boot because of this.

Also add the "10EC5651" HID for the RealTek ALC5651 codec used
in this tablet to the list of HIDs for which not to skipi2c_client
instantiation, since the Intel SST sound driver relies on
the codec being instantiated through ACPI.

APEI: GHES: correctly return NULL for ghes_get_devices()

[ Upstream commit 9368aa1882ac7178adcd936cee5f0899dbf76dc4 ]

Since 315bada690e0 ("EDAC: Check for GHES preference in the
chipset-specific EDAC drivers"), vendor specific EDAC driver will not
probe correctly when CONFIG_ACPI_APEI_GHES is enabled but no GHES device
is present.  Make ghes_get_devices() return NULL when the GHES device
list is empty to fix the problem.

ACPI: sleep: Avoid breaking S3 wakeup due to might_sleep()

2023-06-15T16:05:19+00:00

The addition of might_sleep() to down_timeout() caused the latter to
enable interrupts unconditionally in some cases, which in turn broke
the ACPI S3 wakeup path in acpi_suspend_enter(), where down_timeout()
is called by acpi_disable_all_gpes() via acpi_ut_acquire_mutex().

Namely, if CONFIG_DEBUG_ATOMIC_SLEEP is set, might_sleep() causes
might_resched() to be used and if CONFIG_PREEMPT_VOLUNTARY is set,
this triggers __cond_resched() which may call preempt_schedule_common(),
so __schedule() gets invoked and it ends up with enabled interrupts (in
the prev == next case).

Now, enabling interrupts early in the S3 wakeup path causes the kernel
to crash.

Address this by modifying acpi_suspend_enter() to disable GPEs without
attempting to acquire the sleeping lock which is not needed in that code
path anyway.
