df83d1ebc9 drm/amdgpu: add sched sync for amdgpu job v2
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.

3b4d68e993 drm/amdgpu:use FRAME_CNTL for new GFX ucode (v2)
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.

30514decb2 drm/amdgpu: fix dependency issue
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.

e9d672b291 drm/amdgpu:changes in gfx DMAframe scheme (v2)
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

f54d186700 dma-buf: Rename struct fence to dma_fence
I plan to usurp the short name of struct fence for a core kernel struct,
and so I need to rename the specialised fence/timeline for DMA
operations to make room.

A consensus was reached in
https://lists.freedesktop.org/archives/dri-devel/2016-July/113083.html
that making clear this fence applies to DMA operations was a good thing.
Since then the patch has grown a bit as usage increases, so hopefully it
remains a good thing!

(v2...: rebase, rerun spatch)
v3: Compile on msm, spotted a manual fixup that I broke.
v4: Try again for msm, sorry Daniel

c5637837ba drm/amdgpu: keep vm in job instead of ib (v2)
ib.vm is a legacy way to get vm, after scheduler
implemented vm should be get from job, and all ibs
from one job share the same vm, no need to keep ib.vm
just move vm field to job.

this patch as well add job as paramter to ib_schedule
so it can get vm from job->vm.

v2: agd: sqaush in:
drm/amdgpu: check if ring emit_vm_flush exists in vm flush

No vm flush on engines that don't support VM.

cc55c45db5 drm/amdgpu: give a fence param to ib_free
thus amdgpu_ib_free() can hook sched fence to SA manager
in later patches.

BTW:
for amdgpu_free_job(), it should only fence_put() the
fence of the last ib once, so fix it as well in this patch.
