Jerome Glisse 225758d8ba drm/radeon/kms: fence cleanup + more reliable GPU lockup detection V4 ... This patch cleanup the fence code, it drops the timeout field of fence as the time to complete each IB is unpredictable and shouldn't be bound. The fence cleanup lead to GPU lockup detection improvement, this patch introduce a callback, allowing to do asic specific test for lockup detection. In this patch the CP is use as a first indicator of GPU lockup. If CP doesn't make progress during 1second we assume we are facing a GPU lockup. To avoid overhead of testing GPU lockup frequently due to fence taking time to be signaled we query the lockup callback every 500msec. There is plenty code comment explaining the design & choise inside the code. This have been tested mostly on R3XX/R5XX hw, in normal running destkop (compiz firefox, quake3 running) the lockup callback wasn't call once (1 hour session). Also tested with forcing GPU lockup and lockup was reported after the 1s CP activity timeout. V2 switch to 500ms timeout so GPU lockup get call at least 2 times in less than 2sec. V3 store last jiffies in fence struct so on ERESTART, EBUSY we keep track of how long we already wait for a given fence V4 make sure we got up to date cp read pointer so we don't have false positive Signed-off-by: Jerome Glisse <jglisse@redhat.com> Signed-off-by: Dave Airlie <airlied@redhat.com>		2010-04-06 10:42:45 +10:00
