This has turned out to be really handy in debug so far. Update: Since writing this patch, I've gotten similar code upstream for error state. I've used it quite a bit in debugfs however, and I'd like to keep it here at least until preemption is working. Signed-off-by: Ben Widawsky <ben@bwidawsk.net> This patch was accidentally dropped in the first Execlists version, and it has been very useful indeed. Put it back again, but as a standalone debugfs file. Signed-off-by: Oscar Mateo <oscar.mateo@intel.com> v2: Take the device struct_mutex rather than mode_config mutex for atomic state capture.
