2024-06-07ACPI: x86: Force StorageD3Enable on more productsMario Limonciello
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.

Commit 073237281a50 ("ACPI: PM: s2idle: Enable Low-Power S0 Idle MSFT UUID for non-AMD systems") attempted to avoid evaluating the same Low- Power S0 Idle _DSM functions for different UUIDs, but that turns out to be a mistake, because some systems in the field are adversely affected by it. Address this by allowing all Low-Power S0 Idle _DSM functions to be evaluated, but still print the message regarding duplication of Low- Power S0 Idle _DSM function sets for different UUIDs.

2024-04-08ACPI: x86: Add PNP_UART1_SKIP quirk for Lenovo Blade2 tabletsHans de Goede
The x86 Android tablets on which quirks to skip looking for a matching UartSerialBus resource and instead unconditionally create a serial bus device (serdev) are necessary there are 2 sorts of serialports: ACPI enumerated highspeed designware UARTs, these are the ones which typcially need to be skipped since they need a serdev for the attached BT HCI. A PNP enumerated UART which is part of the PCU. So far the existing quirks have ignored this. But on the Lenovo Yoga Tablet 2 Pro 1380 models this is used for a custom fastcharging protocol. There is a Micro USB switch which can switch the USB data lines to this uart and then a 600 baud protocol is used to configure the charger for a voltage higher then 5V. Add a new ACPI_QUIRK_PNP_UART1_SKIP quirk type and set this for the existing entry for the Lenovo Yoga Tablet 2 830 / 1050 models. Note this will lead to unnecessarily also creating a serdev for the PCU UART on the 830 / 1050 which don't need this, but the UART is not used otherwise there so that is not a problem.

2024-02-22ACPI: x86: Add DELL0501 handling to acpi_quirk_skip_serdev_enumeration()Hans de Goede
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.

2024-02-12ACPI: PM: s2idle: Enable Low-Power S0 Idle MSFT UUID for non-AMD systemsRafael J. Wysocki
Systems based on Intel platforms that use the MSFT UUID for Low-Power S0 Idle (LPS0) have started to ship, so allow the kernel to use the MSFT UUID in the non-AMD case too, but in that case make it avoid evaluating the same _DSM function for two different UUIDs and prioritize the MSFT one. While at it, combine two MSFT _DSM function mask checks in acpi_s2idle_restore_early() so as to make it reflect the acpi_s2idle_prepare_late() flow more closely and adjust the Modern Standby entry and exit comments slightly. Non-AMD systems that do not support MSFT UUID for Low-power S0 Idle are not expected to be affected by this change in any way. Signed-off-by: Rafael J.

2023-05-18ACPI: x86: Add ACPI_QUIRK_UART1_SKIP for Lenovo Yoga Book yb1-x90f/lHans de Goede
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.

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.

2023-03-07ACPI: x86: Introduce an acpi_quirk_skip_gpio_event_handlers() helperHans de Goede
x86 ACPI boards which ship with only Android as their factory image usually have pretty broken ACPI tables, relying on everything being hardcoded in the factory kernel image and often disabling parts of the ACPI enumeration kernel code to avoid the broken tables causing issues. Part of this broken ACPI code is that sometimes these boards have _AEI ACPI GPIO event handlers which are broken. So far this has been dealt with in the platform/x86/x86-android-tablets.c module, which contains various workarounds for these devices, by it calling acpi_gpiochip_free_interrupts() on gpiochip-s with troublesome handlers to disable the handlers. But in some cases this is too late, if the handlers are of the edge type then gpiolib-acpi.c's code will already have run them at boot. This can cause issues such as GPIOs ending up as owned by "ACPI:OpRegion", making them unavailable for drivers which actually need them. Boards with these broken ACPI tables are already listed in drivers/acpi/x86/utils.c for e.g. acpi_quirk_skip_i2c_client_enumeration(). Extend the quirks mechanism for a new acpi_quirk_skip_gpio_event_handlers() helper, this re-uses the DMI-ids rather then having to duplicate the same DMI table in gpiolib-acpi.c . Also add the new ACPI_QUIRK_SKIP_GPIO_EVENT_HANDLERS quirk to existing boards with troublesome ACPI gpio event handlers, so that the current acpi_gpiochip_free_interrupts() hack can be removed from x86-android-tablets.c .

commit 018d6711c26e4 ("ACPI: x86: Add a quirk for Dell Inspiron 14 2-in-1 for StorageD3Enable") introduced a quirk to allow a system with ambiguous use of _ADR 0 to force StorageD3Enable. It was reported that several more Dell systems suffered the same symptoms. As the list is continuing to grow but these are all Cezanne systems, instead add Cezanne to the CPU list to apply the StorageD3Enable property and remove the whole list. It was also reported that an HP system only has StorageD3Enable on the ACPI device for the first NVME disk, not the second.

2022-12-22ACPI: x86: s2idle: Stop using AMD specific codepath for Rembrandt+Mario Limonciello
After we introduced a module parameter and quirk infrastructure for picking the Microsoft GUID over the SOC vendor GUID we discovered that lots and lots of systems are getting this wrong. The table continues to grow, and is becoming unwieldy. We don't really have any benefit to forcing vendors to populate the AMD GUID. This is just extra work, and more and more vendors seem to mess it up. As the Microsoft GUID is used by Windows as well, it's very likely that it won't be messed up like this. So drop all the quirks forcing it and the Rembrandt behavior. This means that Cezanne or later effectively only run the Microsoft GUID codepath with the exception of HP Elitebook 8*5 G9.
