[PATCH 0/1] Fix gem_ctx_persistence failures with GuC submission

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Should fix below failures with GuC submission for the following tests:
gem_exec_balancer --r noheartbeat
gem_ctx_persistence --r heartbeat-close

Not going to fix:
gem_ctx_persistence --r heartbeat-many
gem_ctx_persistence --r heartbeat-stop

As the above tests change the heartbeat value to 0 (off) after the
context is closed and we have no way to detect that with GuC submission
unless we keep a list of closed but running contexts which seems like
overkill for a non-real world use case. We likely should just skip these
tests with GuC submission.
