In the Linux kernel, the following vulnerability has been resolved:
drm/amd/display: Disable idle reallow as part of command/gpint execution
[Why] Workaroud for a race condition where DMCUB is in the process of committing to IPS1 during the handshake causing us to miss the transition into IPS2 and touch the INBOX1 RPTR causing a HW hang.
[How] Disable the reallow to ensure that we have enough of a gap between entry and exit and we're not seeing back-to-back wake_and_executes.
