Nicholas Kazlauskas de1af9af37 drm/amd/display: Workaround register access in idle race with cursor ... [ Upstream commit b5b6d62515 ] [Why] Cursor update can be pre-empted by a request for setting target flip submission. This causes an issue where we're in the middle of the exit sequence trying to log to DM, but the pre-emption starts another DMCUB command submission that requires being out of idle. The DC lock aqusition can fail, and depending on the DM/OS interface it's possible that the function inserted into this thread must not fail. This means that lock aqusition must be skipped and exit *must* occur. [How] Modify when we consider idle as active. Consider it exited only once the exit has fully finished. Consider it as entered prior to actual notification. Since we're on the same core/thread the cached values are coherent and we'll see that we still need to exit. Once the cursor update resumes it'll continue doing the double exit but this won't cause a functional issue, just a (potential) redundant operation.
