We have a gk20a_busy() call in gk20a_buffer_convert_gpu_to_cde() and we again call gk20a_busy() in gk20a_submit_channel_gpfifo() If gk20a_do_idle() is triggered in between these two calls, then this leads to a deadlock and results in idle failure Hence to avoid this take power refcount in a more fine-grained way i.e. in gk20a_cde_convert() instead of taking in gk20a_buffer_convert_gpu_to_cde() Keep gk20a_cde_execute_buffer() out of the gk20a_busy()/ gk20a_idle() pair since we take power refcount in submit path anyways Add correct error handling path in gk20a_cde_convert() Bug 200287073 Change-Id: Iffea2d4c03f42b47dbf05e7fe8fe2994f9c6b37c Signed-off-by: Deepak Nibade <dnibade@nvidia.com> Reviewed-on: http://git-master/r/1324329 GVS: Gerrit_Virtual_Submit Reviewed-by: Bharat Nihalani <bnihalani@nvidia.com>
