JIRA: EVLR-1004 (*) Refactor the non-stalling interrupt path to execute clear on the top half, so on dGPU case processing of stalling interrupts does not block non-stalling one. (*) Use a worker thread to do semaphore wakeups and allow batching of the non-stalling operations. (*) Fix a bug where some gpus will not properly track the completion of interrupts, preventing safe driver unloads Change-Id: Icc90a3acba544c97ec6a9285ab235d337ab9eefa Signed-off-by: David Nieto <dmartineznie@nvidia.com> Reviewed-on: http://git-master/r/1312796 Reviewed-on: http://git-master/r/1320848 GVS: Gerrit_Virtual_Submit Reviewed-by: Sumeet Gupta <sumeetg@nvidia.com>
