977f7e1068 drm/amdgpu: allocate entities on demand
Currently we pre-allocate entities and fences for all the HW IPs on
context creation and some of which are might never be used.

This patch tries to resolve entity/fences wastage by creating entity
only when needed.

18c6b74e7c drm/amdgpu: Enable DISABLE_BARRIER_WAITCNT for Arcturus
In previous gfx9 parts, S_BARRIER shader instructions are implicitly
S_WAITCNT 0 instructions as well. This setting turns off that
mechanism in Arcturus and beyond. With this, shaders must follow the

after an S_BARRIER.

da2f84ba73 Revert "drm/amd/display: Don't skip link training for empty dongle"
This reverts commit 80adaebd2d.

[WHY]
This change was working around a regression that occured in this:
commit 0301ccbaf6 ("drm/amd/display: DP Compliance 400.1.1 failure")

With the fix to run verify_link_cap when the SINK_COUNT of
dongles becomes non-zero this change is no longer needed.

3eb6d7aca5 drm/amd/display: Retrain dongles when SINK_COUNT becomes non-zero
[WHY]
Two years ago the patch referenced by the Fixes tag stopped running
dp_verify_link_cap_with_retries during DP detection when the reason
for the detection was a short-pulse interrupt. This effectively meant
that we were no longer doing the verify_link_cap training on active
dongles when their SINK_COUNT changed from 0 to 1.

A year ago this was partly remedied with:
commit 80adaebd2d ("drm/amd/display: Don't skip link training for empty dongle")

This made sure that we trained the dongle on initial hotplug (without
connected downstream devices).

This is all fine and dandy if it weren't for the fact that there are
some dongles on the market that don't like link training when SINK_COUNT
is 0 These dongles will in fact indicate a SINK_COUNT of 0 immediately
after hotplug, even when a downstream device is connected, and then
trigger a shortpulse interrupt indicating a SINK_COUNT change to 1.

In order to play nicely we will need our policy to not link train an
active DP dongle when SINK_COUNT is 0 but ensure we train it when the
SINK_COUNT changes to 1.

[HOW]
Call dp_verify_link_cap_with_retries on detection even when the detection
is triggered from a short pulse interrupt.

With this change we can also revert this commit which we'll do in a separate
follow-up change:
commit 80adaebd2d ("drm/amd/display: Don't skip link training for empty dongle")

153ca76021 drm/amd/display: Get fb base and fb offset for DMUB from registers
[Why]
Under some hardware initialization sequences the fb base/fb offset
provided can be zero or hardwareinit can happen too late.

We want to ensure that we always have the correct fb_base/fb_offset
when performing DMCUB hardware initialization so we can do DMCUB
command table offloading during first dc hardware init.

[How]
Read from the DCN registers. VBIOS already filled these in for us.

50d2c6027e drm/amd/display: Do not send training pattern if VS Different
[Why]
The DP 1.4a Spec requires that training pattern only under certain
specific conditions. Currently driver will re-send
training pattern every time voltage swing value changes,
but that should not be the case.

[How]
Do not re-send training pattern every time VS values
are different. Only send it on the first iteration.

43563bc2e6 drm/amd/display: update MSA and VSC SDP on video test pattern request
[why]
On video test pattern request we need to update MSA and VSC so
it will match the requested test pattern dynamic range field.

[how]
Update dynamic range field in MSA and disable VSC as updating VSC
info packet is complicated and not required for test pattern purpose.

240c811ccd drm/amdgpu: fix VRAM partially encroached issue in GDDR6 memory training(V2)
[why]
In GDDR6 BIST training, a certain mount of bottom VRAM will be encroached by
UMC, that causes problems(like GTT corrupted and page fault observed).

[how]
Saving the content of this bottom VRAM to system memory before training, and
restoring it after training to avoid VRAM corruption.
