It would require to reorder the commit log, version log need to move after commit message. Thanks, Anshuman.
Let's enable runtime pm autosuspend by default everywhere. So, we can allow D3hot and bigger power savings on idle scenarios.
But at this time let's not touch the autosuspend_delay time, what caused some regression on our previous attempt.
Also, the latest identified issue on GuC PM has been fixed by commit 1a52faed3131 ("drm/i915/guc: Take GT PM ref when deregistering context")
