Summary
drm/amd/display: Wake DMCUB before executing GPINT commands
Details

In the Linux kernel, the following vulnerability has been resolved:

drm/amd/display: Wake DMCUB before executing GPINT commands

[Why] DMCUB can be in idle when we attempt to interface with the HW through the GPINT mailbox resulting in a system hang.

[How] Add dcwakeandexecutegpint() to wrap the wake, execute, sleep sequence.

If the GPINT executes successfully then DMCUB will be put back into sleep after the optional response is returned.

It functions similar to the inbox command interface.
