drm/amd/display: Wait DMCUB to idle state before reset.

2022-06-01T19:56:48Z

[WHY] Very low rate to cause memory access issue while resetting DMCUB after the halt command was sent to it. The process of stopping fw of DMCUB may be timeout, that means it is not in idle state, such as the window frames may still be kept in cache, so reset by force will cause MMHUB hang. [HOW] After the halt command was sent, keep checking the DMCUB state until it is idle.

drm/amd/display: Only flush delta from last command execution

2021-11-22T19:45:01Z

[Why] We're currently flushing commands that had been previously been flushed or are currently being processed by the DMCUB when we don't immediately wait for idle after command execution. [How] Avoiding reflushing the data by keeping track of the last wptr. We'll treat this as the actual rptr by creating a copy of the inbox and modifying the copy's rptr.

2021-11-17T21:58:11Z

[Why] In DC we want to wait for the INBOX0 HW Lock command to ACK before continuing. This is to ensure that the lock has been successfully acquired before programming HW in DC.
