Title:
Fix power button wakeup with shared IRQs on AMD platforms
Status in HWE Next:

Status in linux-oem-5.14 package in Ubuntu:
In Progress
Status in linux-oem-5.14 source package in Focal:
Fix Released
Bug description:
[Impact]
On some platform designs the the power button wakeup from s0i3 doesn't
work even with the existing changes to IRQ handling for the GPIO
controller.
In these designs the ACPI SCI and GPIO controller share an IRQ. Due to
the way the s2idle loop handles the IRQ for the ACPI SCI the GPIO
controller driver doesn't get a chance to wake the system in this
circumstance.
[Fix]
To fix this rework the existing IRQ handler function to function as a checker
and an IRQ handler depending on the calling arguments.
The patches were cherry-picked from 5.16rc3.
[Test]
This is requested by AMD. The test was done on two systems L15 AMD Gen2 and
P14s AMD Gen2 and both can be waken up by power button presses.
[Where problems could occur]
Risk is low. This only affects AMD platforms with s0i3 enabled.
Suspends/resumes are not affect.
