[PATCH 0/2] ACPI: PM: s2idle: Prevent spurious SCIs from waking up the system

From: Rafael J. Wysocki <hidden>
Date: 2020-02-11 16:54:13
Also in: linux-acpi, linux-pm

Hi All,

On some systems the platform generates spurious SCIs while the system is
suspended to idle and those SCIs are treated as genuine system events after
the rework of the main suspend-to-idle control flow in 5.4.  The patches
here address this problem by adding a mechanism to check whether or not
SCIs generated while the system is suspended to idle are spurious and to
discard the spurious ones.

Patch [1/2] updates ACPICA to provide a way to examine the status bits of
all GPEs enabled at the moment in one go.

Patch [2/2] uses that mechanism to implement the check mentioned above.

This series is on top of https://patchwork.kernel.org/patch/11373185/ which
should appear in linux-next tomorrow.

Thanks!
