When the disk shader cache CI testing was enabled, we started noticing occasional failures on deqp test runs. (Mainly SNB, rarely HSW) Before this change, when we cleared the (in memory) program cache we reused the same bo. Since the disk shader cache quickly restores programs, it appears that this would lead to overwrites of the older program binaries in the in memory program cache that apparently were still executing in some cases. If these programs were still executing, this could cause a GPU hang. This issue is probably not disk shader cache specific, but may have been hidden due to the compiler taking time to recompile programs after the cache was cleared. v2: * Don't add `copy` param to brw_cache_new_bo (Ken) * Call from brw_program_cache_check_size (Ken) Cc: Kenneth Graunke <kenneth@whitecape.org> Cc: mesa-stable@lists.freedesktop.org Signed-off-by: Jordan Justen <jordan.l.justen@intel.com> Reviewed-by: Kenneth Graunke <kenneth@whitecape.org> |
