commit 65a24000808f70ac69bd2a96381fa0c7341f20c0 upstream.

A mistake has been made in the BIOS for some ASICs with NBIO 7.5.1
where some NBIO registers aren't properly setup.

Ensure that they're set during initialization.

<title>Revert "drm/amdgpu: TA unload messages are not actually sent to psp when amdgpu is uninstalled"</title>

[ Upstream commit 39934d3ed5725c5e3570ed1b67f612f1ea60ce03 ]

This reverts commit fac53471d0ea9693d314aa2df08d62b2e7e3a0f8.
The following change: move the drm_dev_unplug call after
amdgpu_driver_unload_kms in amdgpu_pci_remove. The reason is
the following: amdgpu_pci_remove calls drm_dev_unregister
and it should be called first to ensure userspace can't access the
device instance anymore. If we call drm_dev_unplug after
amdgpu_driver_unload_kms then we observe IGT PCI software unplug
test failure (kernel hung) for all ASICs. This is how this
regression was found.

After this revert, the following commands do work not, but it would
be fixed in the next commit:
 - sudo modprobe -r amdgpu
 - sudo modprobe amdgpu

[ Upstream commit 0c2dece8fb541ab07b68c3312a1065fa9c927a81 ]

Use page aligned size to reserve memory usage because page aligned TTM
BO size is used to unreserve memory usage, otherwise no page aligned
size causes memory usage accounting unbalanced.

Change vram_used definition type to int64_t to be able to trigger
WARN_ONCE(adev &amp;&amp; adev-&gt;kfd.vram_used &lt; 0, "..."), to help debug the
accounting issue with warning and backtrace.

Some users have reported flickerng with S/G display.  We've
tried extensively to reproduce and debug the issue on a wide
variety of platform configurations (DRAM bandwidth, etc.) and
a variety of monitors, but so far have not been able to.  We
disabled S/G display on a number of platforms to address this
but that leads to failure to pin framebuffers errors and
blank displays when there is memory pressure or no displays
at all on systems with limited carveout (e.g., Chromebooks).
Add a option to disable this as a debugging option as a
way for users to disable this, depending on their use case,
and for us to help debug this further.

v2: fix typo
