ACPI: x86: Force StorageD3Enable on more products

2024-06-07T18:24:07Z

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.

ACPI: PM: s2idle: Evaluate all Low-Power S0 Idle _DSM functions

2024-04-23T19:50:15Z

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. Fixes: 073237281a50 ("ACPI: PM: s2idle: Enable Low-Power S0 Idle MSFT UUID for non-AMD systems") Closes: https://bugzilla.kernel.org/show_bug.cgi?id=218750 Reported-and-tested-by: Mark Pearson Suggested-by: Mario Limonciello Signed-off-by: Rafael J.

ACPI: x86: Add PNP_UART1_SKIP quirk for Lenovo Blade2 tablets

2024-04-08T14:50:47Z

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.
