drm/amdgpu: Fix per-IB secure flag GFX hang

2020-04-28T20:20:30Z

Since commit "Move to a per-IB secure flag (TMZ)", we've been seeing hangs in GFX. We need to send FRAME CONTROL stop/start back-to-back, every time we flip the TMZ flag. That is, when we transition from TMZ to non-TMZ we have to send a stop with TMZ followed by a start with non-TMZ, and similarly for transitioning from non-TMZ into TMZ. This patch implements this, thus fixing the GFX hang. v1 -> v2: As suggested by Luben, and accept part of implemetation from this patch: - Put "secure" closed to the loop and use optimization - Change "secure" to bool again, and move "secure == -1" out of loop. v3: Small fixes/optimizations.

drm/amdgpu: request reg_val_offs each kiq read reg

2020-04-23T19:06:41Z

According to the current kiq read register method, there will be race condition when using KIQ to read register if multiple clients want to read at same time just like the expample below: 1. client-A start to read REG-0 throguh KIQ 2. client-A poll the seqno-0 3. client-B start to read REG-1 through KIQ 4. client-B poll the seqno-1 5. the kiq complete these two read operation 6. client-A to read the register at the wb buffer and get REG-1 value Therefore, use amdgpu_device_wb_get() to request reg_val_offs for each kiq read register. v2: fix the error remove v3: fix the print typo v4: remove unused variables Signed-off-by: Yintian Tao Reviewed-by: Christian König Signed-off-by: Alex Deucher

This allows IPs to flag whether a specific ring requires a GPU scheduler or not. E.g., sometimes instances of an IP are asymmetric and have different capabilities. Reviewed-by: Christian König Reviewed-by: Hawking Zhang Signed-off-by: Alex Deucher

drm/amdgpu: rework sched_list generation

2020-04-09T14:43:14Z

Generate HW IP's sched_list in amdgpu_ring_init() instead of amdgpu_ctx.c. This makes amdgpu_ctx_init_compute_sched(), ring.has_high_prio and amdgpu_ctx_init_sched() unnecessary. This patch also stores sched_list for all HW IPs in one big array in struct amdgpu_device which makes amdgpu_ctx_init_entity() much more leaner. v2: fix a coding style issue do not use drm hw_ip const to populate amdgpu_ring_type enum v3: remove ctx reference and move sched array and num_sched to a struct use num_scheds to detect uninitialized scheduler list v4: use array_index_nospec for user space controlled variables fix possible checkpatch.pl warnings Signed-off-by: Nirmoy Das Reviewed-by: Christian König Signed-off-by: Alex Deucher
