drm/amdgpu: add sched sync for amdgpu job v2

2017-05-24T21:40:35+00:00

this is an improvement for previous patch, the sched_sync is to store fence that could be skipped as scheduled, when job is executed, we didn't need pipeline_sync if all fences in sched_sync are signalled, otherwise insert pipeline_sync still. v2: handle error when adding fence to sync failed.

drm/amdgpu:use FRAME_CNTL for new GFX ucode (v2)

2017-05-24T21:40:26+00:00

AI affected: CP/HW team requires KMD insert FRAME_CONTROL(end) after the last IB and before the fence of this DMAframe. this is to make sure the cache are flushed, and it's a must change no matter MCBP/SR-IOV or bare-metal case because new CP hw won't do the cache flush for each IB anymore, it just leaves it to KMD now. with this patch, certain MCBP hang issue when rendering vulkan/chained-ib are resolved. v2: drop gfx8 changes. gfx8 is not affected (Alex) Signed-off-by: Monk Liu Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: fix dependency issue

2017-05-10T17:23:53+00:00

The problem is that executing the jobs in the right order doesn't give you the right result because consecutive jobs executed on the same engine are pipelined. In other words job B does it buffer read before job A has written it's result. Signed-off-by: Chunming Zhou Reviewed-by: Christian König Signed-off-by: Alex Deucher

drm/amdgpu: split VMID management by VMHUB

2017-04-28T21:32:18+00:00

This way GFX and MM won't fight for VMIDs any more. Initially disabled since we need to stop flushing all HUBS at the same time as well. Signed-off-by: Christian König Reviewed-by: Andres Rodriguez Acked-by: Alex Deucher Signed-off-by: Alex Deucher

drm/amdgpu:changes in gfx DMAframe scheme (v2)

2017-03-30T03:55:42+00:00

1) Adapt to vulkan: Now use double SWITCH BUFFER to replace the 128 nops w/a, because when vulkan introduced, umd can insert 7 ~ 16 IBs per submit which makes 256 DW size cannot hold the whole DMAframe (if we still insert those 128 nops), CP team suggests use double SWITCH_BUFFERs, instead of tricky 128 NOPs w/a. 2) To fix the CE VM fault issue when MCBP introduced: Need one more COND_EXEC wrapping IB part (original one us for VM switch part). this change can fix vm fault issue caused by below scenario without this change: >CE passed original COND_EXEC (no MCBP issued this moment), proceed as normal. >DE catch up to this COND_EXEC, but this time MCBP issued, thus DE treats all following packages as NOP. The following VM switch packages now looks just as NOP to DE, so DE dosen't do VM flush at all. >Now CE proceeds to the first IBc, and triggers VM fault, because DE didn't do VM flush for this DMAframe. 3) change estimated alloc size for gfx9. with new DMAframe scheme, we need modify emit_frame_size for gfx9 4) No need to insert 128 nops after gfx8 vm flush anymore because there was double SWITCH_BUFFER append to vm flush, and for gfx7 we already use double SWITCH_BUFFER following after vm_flush so no change needed for it. 5) Change emit_frame_size for gfx8 v2: squash in BUG removal from Monk Signed-off-by: Monk Liu Acked-by: Alex Deucher Signed-off-by: Alex Deucher
