8159c796b6 drm/i915: Keep the AKSV details in intel_dp_hdcp_write_an_aksv()
Let's try to keep the details on the AKSV stuff concentrated
in one place. So move the control bit and +5 data size handling
there.

v2: Increase txbuf[] to include the payload which intel_dp_aux_xfer()
    will still load into the registers even though the hardware
    will ignore it

fee0fddc1d drm/i915/gen9, gen10: Disable FBC on planes with a misaligned Y-offset
Enabling FBC on a plane having a Y-offset that isn't divisible by 4 may
cause pipe FIFO underruns and flickers, so disable FBC on such a config.

I tried the followings to work around the issue:
- enable each HW work around in ILK_DPFC_CHICKEN
- disable each compression algorithm in ILK_DPFC_CONTROL
- disable low-power watermarks
None of the above got rid of the problem. I haven't found this issue in
the Bspec/WA database either.

Besides the igt testcase below (yet to be merged) an easy way to
reproduce the issue is to enable a plane with FBC and a plane Y-offset
not aligned to 4 and then just enable/disable FBC in a loop, keeping the
plane enabled.

I could trigger the problem on BXT/GLK/SKL/CNL, so assume for now that it's
only present on GEN9 and GEN10.

v2: (Ville)
- Run the test/apply the WA on CNL as well.
- Use IS_GEN() instead of INTEL_GEN().
- Fix spelling.

c8624ede3e drm/i915: Add support for the YCbCr COLOR_RANGE property
Add support for the COLOR_RANGE property on planes. This property
selects whether the input YCbCr data is to treated as limited range
or full range.

On most platforms this is a matter of setting the "YUV range correction
disable" bit, and on VLV/CHV we'll just have to program the color
correction logic to pass the data through unmodified.

b0f5c0badc drm/i915: Add support for the YCbCr COLOR_ENCODING property
Add support for the COLOR_ENCODING plane property which selects
the matrix coefficients used for the YCbCr->RGB conversion. Our
hardware can generally handle BT.601 and BT.709.

CHV pipe B sprites have a fully programmable matrix, so in theory
we could handle anything, but it doesn't seem all that useful to
expose anything beyond BT.601 and BT.709 at this time.

GLK can supposedly do BT.2020, but let's leave enabling that for
the future as well.

38f24f21ae drm/i915: Fix plane YCbCr->RGB conversion for GLK
On GLK the plane CSC controls moved into the COLOR_CTL register.
Update the code to progam the YCbCr->RGB CSC mode correctly when
faced with an YCbCr framebuffer.

The spec is rather confusing as it calls the mode "YUV601 to RGB709".
I'm going to assume that just means it's going to use the YCbCr->RGB
matrix as specified in BT.601 and doesn't actually change the gamut.

5deae91911 drm/i915: Correctly handle limited range YCbCr data on VLV/CHV
Turns out the VLV/CHV fixed function sprite CSC expects full range
data as input. We've been feeding it limited range data to it all
along. To expand the data out to full range we'll use the color
correction registers (brightness, contrast, and saturation).

On CHV pipe B we were actually doing the right thing already because we
progammed the custom CSC matrix to do expect limited range input. Now
that well pre-expand the data out with the color correction unit, we
need to change the CSC matrix to operate with full range input instead.

This should make the sprite output of the other pipes match the sprite
output of pipe B reasonably well. Looking at the resulting pipe CRCs,
there can be a slight difference in the output, but as I don't know
the formula used by the fixed function CSC of the other pipes, I don't
think it's worth the effort to try to match the output exactly. It
might not even be possible due to difference in internal precision etc.

One slight caveat here is that the color correction registers are single
bufferred, so we should really be updating them during vblank, but we
still don't have a mechanism for that, so just toss in another FIXME.

ffed7bd236 drm/i915: Replace open-coded wait-for loop
Now that we can pass arbitrary commands into the base __wait_for()
macro, we can reimplement the open-coded wait-for inside
i915_gem_idle_work_handler() using the new macro. This means that instead
of using ktime, we now use jiffies, and benefit from the exponential sleep
backoff that allows a fast response if the HW settles quickly.

41d3fdcd15 drm/i915/perf: fix perf stream opening lock
We're seeing on CI that some contexts don't have the programmed OA
period timer that directs the OA unit on how often to write reports.

The issue is that we're not holding the drm lock from when we edit the
context images down to when we set the exclusive_stream variable. This
leaves a window for the deferred context allocation to call
i915_oa_init_reg_state() that will not program the expected OA timer
value, because we haven't set the exclusive_stream yet.

367a35a6c6 drm/i915: Don't deref request->ctx inside unlocked print_request()
Although we protect the request itself, we don't lock inside
intel_engine_dump() and so the request maybe retired as we peek into it.
One consequence is that the request->ctx may be freed before we
dereference it, leading to a use-after-free. Replace the hw_id we are
peeking from inside request->ctx with the request->fence.context, with
which we can still track from which context the request originated
(although to tie to HW reports requires a little more legwork, but is
good enough to follow the GEM traces).

5028a4fb7d drm/i915/guc: Fill preempt context once at init time
Since we're inhibiting context save of preempt context, we're no longer
tracking the position of HEAD/TAIL. With GuC, we're adding a new
breadcrumb for each preemption, which means that the HW will do more and
more breadcrumb writes. Eventually the ring is filled, and we're
submitting the preemption context with HEAD==TAIL==0, which won't result
in breadcrumb write, but will trigger hangcheck instead.
Instead of writing a new preempt breadcrumb for each preemption, let's
just fill the ring once at init time (which also saves a couple of
instructions in the tasklet).

v2: Assert that context save restore is inhibited, don't assert on ring
    alignment. (Chris)
v3: Cleanup checkpatch.

ba1c06a572 drm/i915/dp: Fix the order of platforms for setting DP source rates
The usual if ladder order should be from newest to oldest
platform. However the CNL conditional statement was misplaced.
This patch sets the DP source for platforms starting from the newest
to oldest.

9f91280feb drm/i915: Remove the pipe/plane ID checks from skl_check_ccs_aux_surface()
The core now checks that the plane supports the fb's format+modifier
combination, so we can drop the related checks from
skl_check_ccs_aux_surface(). These checks were specific to
SKL/KBL/BXT anyway.

f6322eddaf drm/i915/preemption: Allow preemption between submission ports
Sometimes we need to boost the priority of an in-flight request, which
may lead to the situation where the second submission port then contains
a higher priority context than the first and so we need to inject a
preemption event. To do so we must always check inside
execlists_dequeue() whether there is a priority inversion between the
ports themselves as well as the head of the priority sorted queue, and we
cannot just skip dequeuing if the queue is empty.

As Michał noted, this doesn't simply extend to handling more than 2-port
submission, as we may need to reorder within the array of executing
requests which themselves are lower priority than the first. A task for
later!

Just store function pointers that give us the correct register offsets
instead of storing the register offsets themselves. Slightly less
efficient perhaps but saves a few bytes and better matches how we do
things elsewhere.

v2: Keep a local array of data registers (Chris)

bdabdb6350 drm/i915: Add enum aux_ch and clean up the aux init to use it
Since we no longer have a 1:1 correspondence between ports and AUX
channels, let's give AUX channels their own enum. Makes it easier
to tell the apples from the oranges, and we get rid of the
port E AUX power domain FIXME since we now derive the power domain
from the actual AUX CH.

v2: Rebase due to AUX F
v3: Split out the power domain fix (Rodrigo)
