Workstation application ANSA/META v21.1.4 get this error dmesg when
running CI test suite provided by ANSA/META:
[drm:amdgpu_gem_va_ioctl [amdgpu]] *ERROR* Couldn't update BO_VA (-16)
This is caused by:
1. create a 256MB buffer in invisible VRAM
2. CPU map the buffer and access it causes vm_fault and try to move
it to visible VRAM
3. force visible VRAM space and traverse all VRAM bos to check if
evicting this bo is valuable
4. when checking a VM bo (in invisible VRAM), amdgpu_vm_evictable()
will set amdgpu_vm->evicting, but latter due to not in visible
VRAM, won't really evict it so not add it to amdgpu_vm->evicted
5. before next CS to clear the amdgpu_vm->evicting, user VM ops
ioctl will pass amdgpu_vm_ready() (check amdgpu_vm->evicted)
but fail in amdgpu_vm_bo_update_mapping() (check
amdgpu_vm->evicting) and get this error log
This error won't affect functionality as next CS will finish the
waiting VM ops. But we'd better clear the error log by checking
the amdgpu_vm->evicting flag in amdgpu_vm_ready() to stop calling
amdgpu_vm_bo_update_mapping() later.
Another reason is amdgpu_vm->evicted list holds all BOs (both
user buffer and page table), but only page table BOs' eviction
prevent VM ops. amdgpu_vm->evicting flag is set only for page
table BOs, so we should use evicting flag instead of evicted list
in amdgpu_vm_ready().
The side effect of this change is: previously blocked VM op (user
buffer in "evicted" list but no page table in it) gets done
immediately.

[Why]
Found when running igt@kms_atomic.
Userspace attempts to do a TEST_COMMIT when 0 streams which calls
dc_remove_stream_from_ctx. This in turn calls link_enc_unassign
which ends up modifying stream->link = NULL directly, causing the
global link_enc to be removed preventing further link activity
and future link validation from passing.
[How]
We take care of link_enc unassignment at the start of
link_enc_cfg_link_encs_assign so this call is no longer necessary.
Fixes global state from being modified while unlocked.

In order to fill the drm_display_info structure each time an EDID is
read, the code currently will call drm_add_display_info with the parsed
EDID.
drm_add_display_info will then call drm_reset_display_info to reset all
the fields to 0, and then set them to the proper value depending on the
EDID.
In the color_formats case, we will thus report that we don't support any
color format, and then fill it back with RGB444 plus the additional
formats described in the EDID Feature Support byte.
However, since that byte only contains format-related bits since the 1.4
specification, this doesn't happen if the EDID is following an earlier
specification. In turn, it means that for one of these EDID, we end up
with color_formats set to 0.
The EDID 1.3 specification never really specifies what it means by RGB
exactly, but since both HDMI and DVI will use RGB444, it's fairly safe
to assume it's supposed to be RGB444.
Let's move the addition of RGB444 to color_formats earlier in
drm_add_display_info() so that it's always set for a digital display.

If the only thing that is changing is SAGV vs. no SAGV but
the number of active planes and the total data rates end up
unchanged we currently bail out of intel_bw_atomic_check()
early and forget to actually compute the new WGV point
mask and thus won't actually enable/disable SAGV as requested.
This ends up poorly if we end up running with SAGV enabled
when we shouldn't. Usually ends up in underruns.
To fix this let's go through the QGV point mask computation
if either the data rates/number of planes, or the state
of SAGV is changing.
v2: Check more carefully if things are changing to avoid
the extra calculations/debugs from introducing unwanted
overhead

BIOS may leave a TypeC PHY in a connected state even though the
corresponding port is disabled. This will prevent any hotplug events
from being signalled (after the monitor deasserts and then reasserts its
HPD) until the PHY is disconnected and so the driver will not detect a
connected sink. Rebooting with the PHY in the connected state also
results in a system hang.
Fix the above by disconnecting TypeC PHYs on disabled ports.
Before commit 64851a32c4 the PHY connected state was read out even
for disabled ports and later the PHY got disconnected as a side effect
of a tc_port_lock/unlock() sequence (during connector probing), hence
recovering the port's hotplug functionality.

At boot on the BCM2711, if the HDMI controllers are running, the CRTC
driver will disable itself and its associated HDMI controller to work
around a hardware bug that would leave some pixels stuck in a FIFO.
In order to avoid that issue, we need to run some operations in lockstep
between the CRTC and HDMI controller, and we need to make sure the HDMI
controller will be powered properly.
However, since we haven't enabled it through KMS, the runtime_pm state
is off at this point so we need to make sure the device is powered
through pm_runtime_resume_and_get, and once the operations are complete,
we call pm_runtime_put.
However, the HDMI controller will do that itself in its
post_crtc_powerdown, which means we'll end up calling pm_runtime_put for
a single pm_runtime_get, throwing the reference counting off. Let's
remove the pm_runtime_put call in the CRTC code in order to have the
proper counting.

[How]
If suspend is aborted for some reason during S0i3 resume
cycle, it follows SDMA ring test failing and errors in amdgpu
resume. For RN/CZN/Picasso, SMU saves and restores SDMA
registers during S0ix cycle. So, skipping SDMA suspend and

drm_gem_cma_mmap() cannot assume every implementation of dma_mmap_wc()
will end up calling remap_pfn_range() (which happens to set the relevant
vma flag, among others), so in order to make sure expectations around
VM_DONTEXPAND are met, let it explicitly set the flag like most other
GEM mmap implementations do.
This avoids repeated warnings on a small minority of systems where the
display is behind an IOMMU, and has a simple driver which does not
override drm_gem_cma_default_funcs. Arm hdlcd is an in-tree affected
driver. Out-of-tree, the Apple DCP driver is affected; this fix is
