ffc2674071 drm/vc4: Disable V3D interactions if the v3d component didn't probe.
One might want to use the VC4 display stack without using Mesa.
Similar to the debugfs fixes for not having all of the possible
display bits enabled, make sure you can't oops in vc4 if v3d isn't
enabled.

v2: Fix matching against other v3d variants (review by Paul), don't
    forget to set irq_enabled so that the vblank uapi works
v3: Use -ENODEV instead of -EINVAL on Paul's suggestion.

c9be804c8c drm/vc4: Use common helpers for debugfs setup by the driver components.
The global list of all debugfs entries for the driver was painful: the
list couldn't see into the components' structs, so each component had
its own debugs show function to find the component, then find the
regset and dump it.  The components also had to be careful to check
that they were actually registered in vc4 before dereferencing
themselves, in case they weren't probed on a particular platform.
They routinely failed at that.

Instead, we can have the components add their debugfs callbacks to a
little list in vc4 to be registered at drm_dev_register() time, which
gets vc4_debugfs.c out of the business of knowing the whole list of
components.

Thanks to this change, dsi0 (if it existed) would register its node.

v2: Rebase on hvs_underrun addition.
v3: whitespace fixup

795f672b88 drm/i915: Expose full 1024 LUT entries on ivb+
On ivb+ we can select between the regular 10bit LUT mode with
1024 entries, and the split mode where the LUT is split into
seprate degamma and gamma halves (each with 512 entries). Currently
we expose the split gamma size of 512 as the GAMMA/DEGAMMA_LUT_SIZE.

When using only degamma or gamma (not both) we are wasting half of
the hardware LUT entries. Let's flip that around so that we expose
the full 1024 entries and just throw away half of the user provided
entries when using the split gamma mode.

821062478c drm/i915: Expose the legacy LUT via the GAMMA_LUT/GAMMA_LUT_SIZE props on gen2/3
Just so we don't leave gen2/3 out in the cold let's advertize the
legacy LUT via the GAMMA_LUT/GAMMA_LUT_SIZE props. Without the
GAMMA_LUT prop we can't actually load a LUT using the atomic ioctl
(in preparation for the day of 100% atomic driver).

Supposedly some gen2/3 platforms have an interpolated 10bit gamma mode
as well. It's slightly funkier than the i965+ mode since you have to
specify the slope for the interpolation by hand. But when I tried it
I couldn't get it to work, the hardware just insisted on using the
8bit more regardless of the state of the relevant PIPECONF bit.

c21ce2effc drm/i915: Implement split/10bit gamma for ivb/hsw
Reuse the bdw+ code to get split/10bit gamma for
ivb/hsw. The hardware is nearly identical. The
only slight snag is that on ivb/hsw the precision
palette auto increment mode does not work. So we
must increment the index manually. We'll probably
want to stick to the auto increment mode on bdw+
in the name of efficiency.

Also we want to avoid using the CSC for limited range
RGB output as PIPECONF will take care of that on IVB.

5bda1aca5d drm/i915: Don't use split gamma when we don't have to
Using the split gamma mode when we don't have to has the annoying
requirement of loading a linear LUT to the unused half. Instead
let's make life simpler by switching to the 10bit gamma mode
and duplicating each entry.

This also allows us to load the software gamma LUT into the
hardware degamma LUT, thus removing some of the buggy
configurations we currently allow (YCbCr/limited range RGB
+ gamma LUT). We do still have other configurations that are
also buggy, but those will need more complicated fixes
or they just need to be rejected. Sadly GLK doesn't have
this flexibility anymore and the degamma and gamma LUTs
are very different so no help there.

6752bea8b0 drm/amd/display: Prevent cursor hotspot overflow for RV overlay planes
[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.

71bbe51a08 drm/amd/display: Make pageflip event delivery compatible with VRR.
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.

d2574c33bb drm/amd/display: In VRR mode, do DRM core vblank handling at end of vblank. (v2)
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.

v2: Implement feedback by Nicholas and Paul Menzel.

fdd1fe57c0 drm/amd/display: Rework vrr flip throttling for late vblank irq.
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.

66b0c973d7 drm/amd/display: Prevent vblank irq disable while VRR is active. (v3)
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
    atomic commit by moving the call to the transition
    function outside of plane commit.
    Suggested by Nicholas.

v3: Trivial rebase onto previous patch.

e854194c8b drm/amd/display: Update VRR state earlier in atomic_commit_tail.
We need the VRR active/inactive state info earlier in
the commit sequence, so VRR related setup functions like
amdgpu_dm_handle_vrr_transition() know the final VRR state
when they need to do their hw setup work.

Split update_freesync_state_on_stream() into an early part,
that can run at the beginning of commit tail before the
vrr transition handling, and a late part that must run after
vrr transition handling inside the commit planes code for
enabled crtc's.
