8d6b006e1f drm/virtio: implement context init: handle VIRTGPU_CONTEXT_PARAM_POLL_RINGS_MASK 
For the Sommelier guest Wayland proxy, it's desirable for the
DRM fd to be pollable in response to an host compositor event.
This can also be used by the 3D driver to poll events on a CPU
timeline.

This enables the DRM fd associated with a particular 3D context
to be polled independent of KMS events.  The parameter
VIRTGPU_CONTEXT_PARAM_POLL_RINGS_MASK specifies the pollable
rings.

85c83ea915 drm/virtio: implement context init: allocate an array of fence contexts 
We don't want fences from different 3D contexts (virgl, gfxstream,
venus) to be on the same timeline.  With explicit context creation,
we can specify the number of ring each context wants.

Execbuffer can specify which ring to use.

bbf588d7d4 drm/virtio: implement context init: stop using drv->context when creating fence 
The plumbing is all here to do this.  Since we always use the
default fence context when allocating a fence, this makes no
functional difference.

We can't process just the largest fence id anymore, since it's
it's associated with different timelines.  It's fine for fence_id
260 to signal before 259.  As such, process each fence_id
individually.

e8b6e76f69 drm/virtio: implement context init: plumb {base_fence_ctx, ring_idx} to virtio_gpu_fence_alloc 
These were defined in the previous commit. We'll need these
parameters when allocating a dma_fence.  The use case for this
is multiple synchronizations timelines.

The maximum number of timelines per 3D instance will be 32. Usually,
only 2 are needed -- one for CPU commands, and another for GPU
commands.

As such, we'll need to specify these parameters when allocating a
dma_fence.

vgdev->fence_drv.context is the "default" fence context for 2D mode
and old userspace.

7547675b84 drm/virtio: implement context init: track {ring_idx, emit_fence_info} in virtio_gpu_fence 
Each fence should be associated with a [fence ID, fence_context,
seqno].  The seqno number is just the fence id.

To get the fence context, we add the ring_idx to the 3D context's
base_fence_ctx.  The ring_idx is between 0 and 31, inclusive.

Each 3D context will have it's own base_fence_ctx. The ring_idx will
be emitted to host userspace, when emit_fence_info is true.

4fb530e5ca drm/virtio: implement context init: support init ioctl 
This implements the context initialization ioctl.  A list of params
is passed in by userspace, and kernel driver validates them.  The
only currently supported param is VIRTGPU_CONTEXT_PARAM_CAPSET_ID.

If the context has already been initialized, -EEXIST is returned.
This happens after Linux userspace does dumb_create + followed by
opening the Mesa virgl driver with the same virtgpu instance.

However, for most applications, 3D contexts will be explicitly
initialized when the feature is available.

98122e63a7 drm/amdgpu: check tiling flags when creating FB on GFX8- 
On GFX9+, format modifiers are always enabled and ensure the
frame-buffers can be scanned out at ADDFB2 time.

On GFX8-, format modifiers are not supported and no other check
is performed. This means ADDFB2 IOCTLs will succeed even if the
tiling isn't supported for scan-out, and will result in garbage
displayed on screen [1].

Fix this by adding a check for tiling flags for GFX8 and older.
The check is taken from radeonsi in Mesa (see how is_displayable
is populated in gfx6_compute_surface).

Changes in v2: use drm_WARN_ONCE instead of drm_WARN (Michel)

083fa05bba drm/amd/display: Fix Display Flicker on embedded panels 
[Why]
ASSR is dependent on Signed PSP Verstage to enable Content
Protection for eDP panels. Unsigned PSP verstage is used
during development phase causing ASSR to FAIL.
As a result, link training is performed with
DP_PANEL_MODE_DEFAULT instead of DP_PANEL_MODE_EDP for
eDP panels that causes display flicker on some panels.

[How]
- Do not change panel mode, if ASSR is disabled
- Just report and continue to perform eDP link training
with right settings further.

93ee1a2c0f drm/panel: support for BOE and INX video mode panel 
Support for these two panels fits in nicely with the existing
panel-boe-tv101wum-nl6 driver as suggested by Sam [1].
This is an incell IC, TDDI use time division multiplexing.
Init code effect touch sensing.The main things
we needed to handle were:
a) These panels need slightly longer delays in two places. Since these
new delays aren't much longer, let's just unconditionally increase
them for the driver.
b) These panel use video BURST mode

The auo,b101uan08.3 panel (already supported by this driver) has
a 3.3V rail that needs to be turned on. For previous users of
this panel this voltage was directly output by pmic. On a new
user (the not-yet-upstream sc7180-trogdor-mrbland board) we need
to turn the 3.3V rail on. Add support in the driver for this.

43dc2ad561 drm/amd/display: Fix MST link encoder availability check. 
[Why]
MST streams share the same link and should share the same encoder.
The current availability check may erroneously determine that an
encoder is unavailable for MST streams.

[How]
When checking for link encoder availability, check if an encoder
in use shares a link with the stream for which the availability
check is being conducted. If the link is shared, then the link
encoder should be shared too and will be deemed available.
