[Why]
The actual position for the cursor on the screen is essentially:
x_out = x - x_plane - x_hotspot
y_out = y - y_plane - y_hotspot
The register values for cursor position and cursor hotspot need to be
greater than zero when programmed, but we also need to subtract off
the plane position to display the cursor at the correct position.
Since we don't want x or y to be less than zero, we add the plane
position as a positive value to x_hotspot or y_hotspot. However, what
this doesn't take into account is that the hotspot registers are limited
by the maximum cursor size.
On DCN10 the cursor hotspot regitsers are masked to 0xFF, so they have
a maximum value of 0-255. Values greater this will wrap, causing the
cursor to display in the wrong position.
In practice this means that for sufficiently large plane positions, the
cursor will be drawn twice on the screen, and can cause screen flashes
or p-state WARNS depending on what the wrapped value is.
So we need a way to remove the value from x_plane and y_plane without
exceeding the maximum cursor size.
[How]
Subtract as much as x_plane/y_plane as possible from x and y and place
the remainder in the cursor hotspot register.
The value for x_hotspot and y_hotspot can still wrap around but it
won't happen in a case where the cursor is actually enabled.
The cursor plane needs to intersect at least one pixel of the plane's
rectangle to be enabled, so the cursor position + hotspot provided by
userspace must always be strictly less than the maximum cursor size for
the cursor to actually be enabled.

We want vblank counts and timestamps of flip completion as sent
in pageflip completion events to be consistent with the vblank
count and timestamp of the vblank of flip completion, like in non
VRR mode.
In VRR mode, drm_update_vblank_count() - and thereby vblank
count and timestamp updates - must be delayed until after the
end of front-porch of each vblank, as it is only safe to
calculate vblank timestamps outside of the front-porch, when
we actually know when the vblank will end or has ended.
The function drm_update_vblank_count() which updates timestamps
and counts gets called by drm_crtc_accurate_vblank_count() or by
drm_crtc_handle_vblank().
Therefore we must make sure that pageflip events for a completed
flip are only sent out after drm_crtc_accurate_vblank_count() or
drm_crtc_handle_vblank() is executed, after end of front-porch
for the vblank of flip completion.
Two cases:
a) Pageflip irq handler executes inside front-porch:
In this case we must defer sending pageflip events until
drm_crtc_handle_vblank() executes after end of front-porch,
and thereby calculates proper vblank count and timestamp.
Iow. the pflip irq handler must just arm a pageflip event
to be sent out by drm_crtc_handle_vblank() later on.
b) Pageflip irq handler executes after end of front-porch, e.g.,
after flip completion in back-porch or due to a massively
delayed handler invocation into the active scanout of the new
frame. In this case we can call drm_crtc_accurate_vblank_count()
to safely force calculation of a proper vblank count and
timestamp, and must send the pageflip completion event
ourselves from the pageflip irq handler.
This is the same behaviour as needed for standard fixed refresh
rate mode.
To decide from within pageflip handler if we are in case a) or b),
we check the current scanout position against the boundary of
front-porch. In non-VRR mode we just do what we did in the past.

In VRR mode, proper vblank/pageflip timestamps can only be computed
after the display scanout position has left front-porch. Therefore
delay calls to drm_crtc_handle_vblank(), and thereby calls to
drm_update_vblank_count() and pageflip event delivery, to after the
end of front-porch when in VRR mode.
We add a new vupdate irq, which triggers at the end of the vupdate
interval, ie. at the end of vblank, and calls the core vblank handler
function. The new irq handler is not executed in standard non-VRR
mode, so vblank handling for fixed refresh rate mode is identical
to the past implementation.

For throttling to work correctly, we always need a baseline vblank
count last_flip_vblank that increments at start of front-porch.
This is the case for drm_crtc_vblank_count() in non-VRR mode, where
the vblank irq fires at start of front-porch and triggers DRM core
vblank handling, but it is no longer the case in VRR mode, where
core vblank handling is done later, after end of front-porch.
Therefore drm_crtc_vblank_count() is no longer useful for this.
We also can't use drm_crtc_accurate_vblank_count(), as that would
screw up vblank timestamps in VRR mode when called in front-porch.
To solve this, use the cooked hardware vblank counter returned by
amdgpu_get_vblank_counter_kms() instead, as that one is cooked to
always increment at start of front-porch, independent of when
vblank related irq's fire.
This patch allows vblank irq handling to happen anywhere within
vblank of even after it, without a negative impact on flip
throttling, so followup patches can shift the vblank core
handling trigger point wherever they need it.

During VRR mode we can not allow vblank irq dis-/enable
transitions, as an enable after a disable can happen at
an arbitrary time during the video refresh cycle, e.g.,
with a high likelyhood inside vblank front-porch. An
enable during front-porch would cause vblank timestamp
updates/calculations which are completely bogus, given
the code can't know when the vblank will end as long
as we are in front-porch with no page flip completed.
Hold a permanent vblank reference on the crtc while
in active VRR mode to prevent a vblank disable, and
drop the reference again when switching back to fixed
refresh rate non-VRR mode.
v2: Make sure transition is also handled if vrr is
disabled and stream gets disabled in the same

UAPI Changes:
- Make mmap code more asynchronous. Avoid full SET_DOMAIN on GTT mmap pagefault,
and flushes pages on acquisition instead. Moves some of the work from mmap fault
time to execbuf time to avoid lock contention during mmap access.
Has neutral to positive impact on perf as the flushing moves to execbuf time
in real world workloads on the current known userspaces due to recycling of BOs.
If there exist an unknown non-recycling userspace, they should explicitly do the
SET_DOMAIN and not rely on kernel doing implicit SET_DOMAIN because swapout/in
might have happenedt.

This patch moves the virtio_gpu_cmd_create_resource() call (which
notifies the host about the new resource created) into the
virtio_gpu_object_create() function. That way we can call
virtio_gpu_cmd_create_resource() before ttm_bo_init(), so the host
already knows about the object when ttm initializes the object and calls
our driver callbacks.
Specifically the object is already created when the
virtio_gpu_ttm_tt_bind() callback invokes virtio_gpu_object_attach(),
so the extra virtio_gpu_object_attach() calls done after
virtio_gpu_object_create() are not needed any more.
The fence support for the create ioctl becomes a bit more tricky though.
The code moved into virtio_gpu_object_create() too. We first submit the
(fenced) virtio_gpu_cmd_create_resource() command, then initialize the
ttm object, and finally attach just created object to the fence for the
command in case it didn't finish yet.
