From e4a7bc1602cc9a041dabee4da4a16594f2f9552a Mon Sep 17 00:00:00 2001 From: Deepak Nibade Date: Wed, 17 Sep 2014 12:37:52 +0530 Subject: gpu: nvgpu: add API to recover TSG - add and export API "gk20a_fifo_recover_tsg()" to recover a TSG - if TSG is running on any engine, then trigger MMU fault on those engines - otherwise, abort each channel in TSG - modify channel specific API engines_on_ch() to generic engines_on_id() which will take an ID and a flag to specify whether ID is for channel or TSG and return engines running on that ID - modify channel specific API get_faulty_channel() to generic get_faulty_id_type() which will take pointers to ID and type of ID (either a regular channel or TSG) - remove runlist update from recover_ch() since no need to touch runlist during recovery - set error notifier first and then only abort the channels for TSG recovery path - also, add necessary accessors to get engine status type as TSG Bug 1470692 Change-Id: I7137f611f80916b3d256d4b0dc6e5cf1e93eef6f Signed-off-by: Deepak Nibade Reviewed-on: http://git-master/r/497873 Reviewed-by: Automatic_Commit_Validation_User GVS: Gerrit_Virtual_Submit Reviewed-by: Terje Bergstrom --- drivers/gpu/nvgpu/gk20a/fifo_gk20a.h | 1 + 1 file changed, 1 insertion(+) (limited to 'drivers/gpu/nvgpu/gk20a/fifo_gk20a.h') diff --git a/drivers/gpu/nvgpu/gk20a/fifo_gk20a.h b/drivers/gpu/nvgpu/gk20a/fifo_gk20a.h index 04d22abb..e7560e27 100644 --- a/drivers/gpu/nvgpu/gk20a/fifo_gk20a.h +++ b/drivers/gpu/nvgpu/gk20a/fifo_gk20a.h @@ -163,6 +163,7 @@ int gk20a_fifo_suspend(struct gk20a *g); bool gk20a_fifo_mmu_fault_pending(struct gk20a *g); void gk20a_fifo_recover(struct gk20a *g, u32 engine_ids, bool verbose); void gk20a_fifo_recover_ch(struct gk20a *g, u32 hw_chid, bool verbose); +void gk20a_fifo_recover_tsg(struct gk20a *g, u32 tsgid, bool verbose); int gk20a_init_fifo_reset_enable_hw(struct gk20a *g); void gk20a_init_fifo(struct gpu_ops *gops); -- cgit v1.2.2
