cf2f0a3720 drm/amdgpu: enable huge page handling in the VM v5
The hardware can use huge pages to map 2MB of address space with only one PDE.

v2: few cleanups and rebased
v3: skip PT updates if we are using the PDE
v4: rebased, added support for CPU based updates
v5: fix CPU based updates once more
v6: fix ndw estimation

We need to wait with the correct owner on unmap operations or otherwise can run

Also always wait for the page directory since this is where the reservation
object comes from. So rename the function to amdgpu_vm_wait_pd instead as well.

8fdf074f18 drm/amdgpu:fix world switch hang
for SR-IOV, we must keep the pipeline-sync in the protection
of COND_EXEC, otherwise the command consumed by CPG is not
consistent when world switch triggerd, e.g.:

world switch hit and the IB frame is skipped so the fence
won't signal, thus CP will jump to the next DMAframe's pipeline-sync
command, and it will make CP hang foever.

after pipelin-sync moved into COND_EXEC the consistency can be
guaranteed

BIT0 controls Graphics and BIT1 Compute.

 BIT1 [= 0] Compute updated by SDMA [= 1] by CPU

By default, only for large BAR system vm_update_mode = 2, indicating
that Graphics VMs will be updated via SDMA and Compute VMs will be
updated via CPU. And for all all other systems (by default)
vm_update_mode = 0

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

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

b0456f9306 drm/amdgpu: write PTEs directly into the IB.
Write the PTEs at the end of the IB instead of directly into the SDMA commands.
This can save quite some CPU cycles building the entries.

This doesn't change the DW estimation because PTEs where embedded into the IB
before as well. It just moves them to the end of the IB.
