Maarten Lankhorst 945ac78928 drm/i915: Force planar YUV coordinates to be a multiple of 2, v2.
We can't make NV12 work any other way. The scaler doesn't handle odd
coordinates well, and we will get visual corruption on the screen.

Changes since v1:
- Put the check in intel_plane_check_src_coordinates. (Ville)

Ville Syrjälä 1ee516ffa7 drm/i915: Fix logic fumble in rotation vs. ccs check
Smatch reports:
../drivers/gpu/drm/i915/intel_sprite.c:1192 skl_plane_check_fb() warn: was || intended here instead of &&?

Obviously smatch is correct here since we're trying to check if we're
using either of the ccs modifiers. Since we now have is_ccs_modifier()
let's use it to fix this.

having to pick between the normal vs. rotated stride during hardware

no longer match the fb stride so we'll need a place to store it
anyway.

Tarun Vyas c3d433617d drm/i915: Use crtc_state->has_psr instead of CAN_PSR for pipe update
In commit "drm/i915: Wait for PSR exit before checking for vblank
evasion", the idea was to limit the PSR IDLE checks when PSR is
actually supported. While CAN_PSR does do that check, it doesn't
applies on a per-crtc basis. crtc_state->has_psr is a more granular
check that only applies to pipe(s) that have PSR enabled.

Without the has_psr check, we end up waiting on the eDP transcoder's
PSR_STATUS register irrespective of whether the pipe being updated is
driving it or not.

v2: Remove unnecessary parantheses, make checkpatch happy.

v3: Move the has_psr check to intel_psr_wait_for_idle and commit
    message changes (DK).

v4: Derive dev_priv from intel_crtc_state (DK)

v5: Commit message changes to reflect the HW behavior (DK)

Tarun Vyas a608987970 drm/i915: Wait for PSR exit before checking for vblank evasion
The PIPEDSL freezes on PSR entry and if PSR hasn't fully exited, then
the pipe_update_start call schedules itself out to check back later.

On ChromeOS-4.4 kernel, which is fairly up-to-date w.r.t drm/i915 but
lags w.r.t core kernel code, hot plugging an external display triggers
tons of "potential atomic update errors" in the dmesg, on *pipe A*. A
closer analysis reveals that we try to read the scanline 3 times and
eventually timeout, b/c PSR hasn't exited fully leading to a PIPEDSL
stuck @ 1599. This issue is not seen on upstream kernels, b/c for *some*
reason we loop inside intel_pipe_update start for ~2+ msec which in this
case is more than enough to exit PSR fully, hence an *unstuck* PIPEDSL
counter, hence no error. On the other hand, the ChromeOS kernel spends
~1.1 msec looping inside intel_pipe_update_start and hence errors out
b/c the source is still in PSR.

Regardless, we should wait for PSR exit (if PSR is disabled, we incur
a ~1-2 usec penalty) before reading the PIPEDSL, b/c if we haven't
fully exited PSR, then checking for vblank evasion isn't actually
applicable.

Ville Syrjälä 672b3c4bc3 drm/i915: Fix sprite destination colorkeying on SKL+
On SKL+ the dst colorkey must be configured on the lower
plane that contains the colorkey. This is in contrast to
most earlier platforms where the dst colorkey is configured
on the plane above.

The hardware will peform dst keying only between two immediately
adjacent (in zorder) planes. Plane 2 will be keyed against plane 1,
plane 3 againts plane 2, and so on. There is no way to key arbitrary
planes against plane 1. Thus offering dst color keying on plane 3+
is pointless. In fact it can be harmful since enabling dst keying on
more than one plane on the same pipe leads to only the top-most of
the planes performing the keying. For any plane lower in zorder the
dst key enable is simply ignored.

v2: s/plane 0/plane 1/ etc. since the hw plane names start from 1
    Don't break dst colorkey on pre-SKL sprites (hunk ended in the
    wrong patch)

Set up the SKL+ scaler initial phase registers correctly. Otherwise
we start fetching the data from the center of the first pixel instead
of the top-left corner, which obviously then leads to right/bottom edges
replicating data excessively as the data runs out half a pixel too soon.

Ville Syrjälä eade6c8944 drm/i915: Have plane->get_hw_state() return the current pipe
Like we do for encoder let's make the plane->get_hw_state() return
the pipe to which the plane is currently attached. We don't currently
allow planes to move between the pipes, but perhaps one day we will.

In either case this makes the code more uniform and perhaps makes
intel_plane_mapping_ok() slightly more clear.

Note that for i965 and g4x planes A and B still have pipe select bits
but they're hardwired to pipe A and B respectively. This means we can
safely interpret those bits just like on gen2/3. This allows the
same readout code work for plane C (which can still be assigned
to eiter pipe on i965) should we ever expose it.

g4x no longer allows moving the cursor planes between the pipes,
but the pipe select bits can still be set in the register. Thus
we have to ignore those bits. OTOH i965 still allows the cursors
to move between pipes thus we have to trust the bits there.

Ville Syrjälä a38189c5f7 drm/i915: Promote .format_mod_supported() to the lead role
Up to now we've used the plane's modifier list as the primary
source of information for which modifiers are supported by a
given plane. In order to allow auxiliary metadata to be embedded
within the bits of the modifier we need to stop doing that.

Thus we have to make .format_mod_supported() aware of the plane's
capabilities and gracefully deal with any modifier being passed
in directly from userspace.

Maarten Lankhorst 9c1659ebe7 drm/i915: Do not adjust scale when out of bounds, v2.
With the previous patch drm_atomic_helper_check_plane_state correctly
calculates clipping and the xf86-video-intel ddx is fixed to fall back
to GPU correctly when SetPlane fails, we can remove the hack where
we try to pan/zoom when out of min/max scaling range. This was already
poor behavior where the screen didn't show what was requested, and now
instead we reject it outright. This simplifies check_sprite_plane a lot.

Changes since v1:
- Set crtc_h to the height correctly.
- Reject < 3x3 rectangles instead of making them invisible for <gen9.
  For gen9+ skl_update_scaler_plane will reject them.

Maarten Lankhorst f96bdf564f drm/rect: Handle rounding errors in drm_rect_clip_scaled, v3.
Instead of relying on a scale which may increase rounding errors,
clip src by doing: src * (dst - clip) / dst and rounding the result
away from 1, so the new coordinates get closer to 1. We won't need
to fix up with a magic macro afterwards, because our scaling factor
will never go to the other side of 1.

Changes since v1:
- Adjust dst immediately, else drm_rect_width/height on dst gives bogus
  results.
Change since v2:
- Get rid of macros and use 64-bits math.

Tarun 9ba59b79dc drm/i915: Remove redundant check for negative timeout while doing an atomic pipe update
No functional changes, just a minor knit. Stumbled across the kernel doc for
schedule_timeout() which quotes "In all cases the return value is guaranteed
to be non-negative". Also, the return code of schedule_timeout() already checks
for negative values "return timeout < 0 ? 0 : timeout;" and returns 0
in such cases. Furthermore, the msec_to_jiffies returns an ungined long
value. So, let's do away with the redundant check for an atomic
pipe update.

v10: Rebased (me)

v11: Addressed review comments from Shashank Sharma
Alignment issues fixed.
When call to skl_update_scaler is made, 0 was being
sent instead of pixel_format.
When crtc update scaler is called, we dont have the
fb to derive the pixel format. Added the function
parameter bool plane_scaler_check to account for this.

v12: Fixed failure in IGT debugfs_test.
fb is NULL in skl_update_scaler_plane
Due to this, accessing fb->format caused failure.
Patch checks fb before using.

v13: In the previous version there was a flaw.
In skl_update_scaler during plane_scaler_check
if the format was non-NV12, it would set need_scaling
to false. This could reset the previously set need_scaling
from a previous condition check. Patch fixes this.
Patch also adds minimum src height for YUV 420 formats
to 16 (as defined in BSpec) and adds for checking this
range.

v14: Addressed review comments from Maarten
Just add a check for NV12 min src height in
skl_update_scaler and retain the remaining checks
as is. Added Reviewed By from Juha-Pekka Heikkila.

v15: Rebased the series.

v16: Changed fb height restriction to be >= 16 as per
Bspec. Earlier it was > 16.

v17: Adding src width and height to be mult of 4 restriction
to avoid pipe fifo underruns for NV12.

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.

Ville Syrjälä 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.

Ville Syrjälä 6a20fe7b17 drm/i915: Give all ioctl functions an _ioctl suffix
Most of our ioctl functions have an _ioctl suffix in the name. I like
that idea since it makes it easy to figure out how the function is
going to get called. Rename the handful of exceptions to follow the
same pattern.

Ville Syrjälä 89746e790a drm/i915: Reject undefined colorkey flags

ioctl flags.

Ville Syrjälä 6ec5bd3489 drm/i915: Deprecate I915_SET_COLORKEY_NONE
Deprecate the silly I915_SET_COLORKEY_NONE flag. The obvious
way to disable colorkey is to just set flags to 0, which is
exactly what the intel ddx has been doing all along.

Currently when userspace sets the flags to 0, we end up in a
funny state where colorkey is disabled, but various colorkey
vs. scaling checks still consider colorkey to be enabled, and
thus we don't allow plane scaling to kick in.

In case there is some other userspace out there that actually
uses this flag (unlikely as this is an i915 specific uapi)
we'll keep on accepting it.
