Before enabling new crtc, stream_count in dc_state does not sync with
that in drm_atomic_state. Validating dsc in such case would leave newly
added stream not jointly participating in dsc optimization with existing
streams, but simply using default initialized vcpi all the time which
gives wrong dsc determination decision.
Consider the scenaio where one 4k60 connected to the dock under dp-alt mode.
Since dp-alt mode is 2-lane setup, stream 1 consumes 63 slots with dsc needed.
Then hook up a second 4k60 to the dock.
stream 2 connected with 65 slot initialized by default without dsc. dsc
pre validate will not jointly optimize stream 2 with stream 1 before
crtc 2 added into the dc_state. That leads to stream 2 not getting dsc
optimization, and trigger atomic_check failure all the time, as 65 > 63
limit.
After getting all new crtcs added into the state, stream_count in
dc_state correctly reflect that in drm_atomic_state which comes up with
correct dsc decision.

Currently we do the DRIVER_ATOMIC disable as almost the
first thing during pci probe. That involves the use of
DISPLAY_VER() which is perhaps a bit sketchy now that we
may need to read that out from the hardware itself.
Looks like we do populate a default value for it anyway
so the current does at least still work.
But let's make this safer anyway and move the code
into intel_device_info_runtime_init() where we also
handle the same thing for the !HAS_DISPLAY case.

While the select subconnector property is stored in the kernel by the

Worse, the select subconnector property is stored in a field called

We currently have two sets of TV properties.
The first one is there to deal with analog TV properties, creating
properties such as the TV mode, subconnectors, saturation, hue and so on.
It's created by calling the drm_mode_create_tv_properties() function.
The second one is there to deal with properties that might be useful on a
TV, creating the overscan margins for example. It's created by calling the
drm_mode_create_tv_margin_properties().
However, we also have a drm_atomic_helper_connector_tv_reset() function
that will reset the TV margin properties to their default values, and thus
is supposed to be called for the latter set. This creates an ambiguity due
to the inconsistent naming.
We can thus rename the drm_atomic_helper_connector_tv_reset() function to
drm_atomic_helper_connector_tv_margins_reset() to remove that ambiguity
and hopefully make it more obvious.

Patch which added graceful exit for non-persistent contexts missed the
fact it is not enough to set the exiting flag on a context and let the
backend handle it from there.
GuC backend cannot handle it because it runs independently in the
firmware and driver might not see the requests ever again. Patch also
missed the fact some usages of intel_context_is_banned in the GuC backend
needed replacing with newly introduced intel_context_is_schedulable.
Fix the first issue by calling into backend revoke when we know this is
the last chance to do it. Fix the second issue by replacing
intel_context_is_banned with intel_context_is_schedulable, which should
always be safe since latter is a superset of the former.

In drm_atomic_helper_check_crtc_state(), do not add a new plane state
to the global state if it does not exist already. Adding a new plane
state will result in overhead for the plane during the atomic-commit
step.
For the test in drm_atomic_helper_check_crtc_state() to succeed, it
is important that the CRTC has an enabled primary plane after the
commit. Simply testing the CRTC state's plane_mask for a primary plane
is sufficient.
Note that the helper still only tests for an attached primary plane.
Drivers have to ensure that the plane contains valid pixel information.

We've excluded gmch platforms from writing the final watermarks
for any disabled pipe. IIRC the reason was perhaps some lingering
issue with the watermark merging across the pipes. But I can't
really see any reason for this anymore, so let's unify this behaviour.
The main benefit being more consistency in register dumps when
we don't have stale watermarks hanging around in the registers.
Functionally there should be no difference as the hardware just
ignore all of it when the pipe is disabled.

On g4x/vlv/chv the hardware seems incapable of changing the pixel
format, rotation, or YUV->RGB CSC matrix while in CxSR.
Additionally on VLV/CHV the sprites seem incapable of tiling
changes while in CxSR. On g4x CxSR is not even possible with
the sprite enabled. Curiously the primary plane seems perfectly
happy when changing tiling during CxSR.
Pimp up the code to account for these when determining whether
CxSR needs to be disabled. Since it looks like most of the plane
control register bits are affected let's just compare that.
But in the name of efficiency we'll make an exception for the
primary plane tiling changes (avoids some extra vblank waits).
