[Impact]
AMD Systems don't enter PC6 at runtime and cause failures to enter s2idle.
Currently the fix is from kernel driver rather than MP2 firmware, which disable interrupts from kernel driver to fix MP2 firmware blocking CPUOFF.

[Impact]
AMD Systems don't enter PC6 at runtime and cause failures to enter s2idle.
Currently the fix is from kernel driver rather than MP2 firmware, which disable interrupts from kernel driver to fix MP2 firmware blocking CPUOFF.
[Fix]
The fixes involve 1) cancelling delayed work when entering s0ix and re-scheduling it when resuming from s0ix, and 2) clearing interrupts during the driver initialization and sensor command operations.
[Test]
This is requested by AMD and was tested on AMD CRB.
[Where problems could occur]
Risk is low to medium. Some code flow changes are guarded by reasonable conditions, but the fixes introduced additional suspend and resume operations.
Having said that, clearing interrupts before driver initialization and cancelling work before entering sleeping states are standard approaches are usually safe. |
