drm/amdgpu: fix deadlock of reservation between cs and gpu reset v2

2017-04-28T21:33:14+00:00

the case could happen when gpu reset: 1. when gpu reset, cs can be continue until sw queue is full, then push job will wait with holding pd reservation. 2. gpu_reset routine will also need pd reservation to restore page table from their shadow. 3. cs is waiting for gpu_reset complete, but gpu reset is waiting for cs releases reservation. v2: handle amdgpu_cs_submit error path.

drm/amdgpu: use a 64bit interval tree for VM management v2

2017-04-04T17:40:32+00:00

This only makes a difference for 32-bit systems. The idea is to have a fixed virtual address space size with 4-level page tables and to minimize differences between 32 and 64-bit systems. v2: Update commit message.

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
