[PATCH 0/8] Adding NV12 support for SKL display

[PATCH 0/8] Adding NV12 support for SKL display

[Vidya Srinivas]

This patch series is adding NV12 support for Skylake display after
rebasing on latest drm-intel-nightly. Initial series of the patches
can be found here:
https://lists.freedesktop.org/archives/intel-gfx/2015-May/066786.html

Feature has been currently tested with custom linux based test tool
IGT test development is under progress. Floating these patches for
initial review. These NV12 patches are dependent on Ville's patches
mentioned below.

Update from last rev:
Patches were initial reviewed last when floated but
currently there was a design change with respect to
- the way fb offset is handled
- the way rotation is handled
Rebase of the current NV12 patch series has been done as per the
current changes on drm-intel-nightly.
Review comments from Ville (12th June 2017) have been addressed

Chandra Konduru (6):
  drm/i915: Set scaler mode for NV12
  drm/i915: Update format_is_yuv() to include NV12
  drm/i915: Upscale scaler max scale for NV12
  drm/i915: Add NV12 as supported format for primary plane
  drm/i915: Add NV12 as supported format for sprite plane
  drm/i915: Add NV12 support to intel_framebuffer_init

Ville Syrjälä (2):

[PATCH 1/8] drm/i915: Implement .get_format_info() hook for CCS

[Vidya Srinivas]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

SKL+ display engine can scan out certain kinds of compressed surfaces
produced by the render engine. This involved telling the display engine
the location of the color control surfae (CCS) which describes which
parts of the main surface are compressed and which are not. The location
of CCS is provided by userspace as just another plane with its own offset.

By providing our own format information for the CCS formats, we should
be able to make framebuffer_check() do the right thing for the CCS
surface as well.

Note that we'll return the same format info for both Y and Yf tiled
format as that's what happens with the non-CCS Y vs. Yf as well. If
desired, we could potentially return a unique pointer for each
pixel_format+tiling+ccs combination, in which case we immediately be
able to tell if any of that stuff changed by just comparing the
pointers. But that does sound a bit wasteful space wise.

v2: Drop the 'dev' argument from the hook
	v3: Include the description of the CCS surface layout
v4: Pretend CCS tiles are regular 128 byte wide Y tiles (Jason)

[PATCH 2/8] drm/i915: Add render decompression support

[Vidya Srinivas]

From: Ville Syrjälä <ville.syrjala@linux.intel.com>

SKL+ display engine can scan out certain kinds of compressed surfaces
produced by the render engine. This involved telling the display engine
the location of the color control surfae (CCS) which describes
which parts of the main surface are compressed and which are not. The
location of CCS is provided by userspace as just another plane with its
own offset.

Add the required stuff to validate the user provided AUX plane metadata
and convert the user provided linear offset into something the hardware
can consume.

Due to hardware limitations we require that the main surface and
the AUX surface (CCS) be part of the same bo. The hardware also
makes life hard by not allowing you to provide separate x/y offsets
for the main and AUX surfaces (excpet with NV12), so finding suitable
offsets for both requires a bit of work. Assuming we still want keep
playing tricks with the offsets. I've just gone with a dumb "search
backward for suitable offsets" approach, which is far from optimal,
		 but it works.

		 Also not all planes will be capable of scanning out compressed surfaces,
		 and eg. 90/270 degree rotation is not supported in combination with
		 decompression either.

		 This patch may contain work from at least the following people:
		 * Vandana Kannan <vandana.kannan@intel.com>
		 * Daniel Vetter <daniel@ffwll.ch>
		 * Ben Widawsky <ben@bwidawsk.net>

	v2: Deal with display workarounds 0390, 0531, 1125 (Paulo)
v3: Pretend CCS tiles are regular 128 byte wide Y tiles (Jason)
	Put the AUX register defines to the correct place
	Fix up the slightly bogus rotation check
	v4: Use I915_WRITE_FW() due to plane update locking changes
s/return -EINVAL/goto err/ in intel_framebuffer_init()
	Eliminate a bunch hardcoded numbers in CCS code

[PATCH 3/8] drm/i915: Set scaler mode for NV12

[Vidya Srinivas]

From: Chandra Konduru <chandra.konduru@intel.com>

This patch sets appropriate scaler mode for NV12 format.
In this mode, skylake scaler does either chroma-upsampling or
chroma-upsampling and resolution scaling

v2: Review comments from Ville addressed
	NV12 case to be checked first for setting
	the scaler

v3: Rebased (me)

small nit on the commit message:
      static function in intel_sprite.c is not available to the primary 
plane functions.

Why are we adding 10 bit RGB formats with the NV12 series patches? 
Trying to set XR30 or AB30 results in error returned even though the 
modes are advertised for the planes.

This NV12 support only correctly works on SKL. Plane color space 
conversion is different on GLK and later platforms causing the colors to 
display incorrectly. Ville's plane color space property patch series in 
review will fix this issue.

[PATCH 0/8] Adding NV12 support

[Vidya Srinivas]

This patch series is adding NV12 support for Broxton display after
rebasing on latest drm-intel-nightly. Initial series of the patches
can be found here:
https://lists.freedesktop.org/archives/intel-gfx/2015-May/066786.html

Feature has been currently tested with custom linux based test tool
IGT test development is under progress. Floating these patches for
initial review. These NV12 patches are dependent on Ville's patches
mentioned below.

Update from last rev:
Patches were initial reviewed last when floated but
currently there was a design change with respect to
- the way fb offset is handled
- the way rotation is handled
Rebase of the current NV12 patch series has been done as per the
current changes on drm-intel-nightly.
Review comments from Ville (12th June 2017) have been addressed
Review comments from Clinton A Taylor (7th July 2017) have been
addressed
Review comments from Clinton A Taylor (10th July 2017) have been
addressed. Had missed out tested-by/reviewed-by in the patches.
Fixed that error in this series.
Review comments from Ville (11th July 2017) addressed.
Review comments from Paauwe, Bob (29th July 2017) addressed.

Chandra Konduru (6):
  drm/i915: Set scaler mode for NV12
  drm/i915: Update format_is_yuv() to include NV12
  drm/i915: Upscale scaler max scale for NV12
  drm/i915: Add NV12 as supported format for primary plane
  drm/i915: Add NV12 as supported format for sprite plane
  drm/i915: Add NV12 support to intel_framebuffer_init

Ville Syrjälä (2):
  drm/i915: Implement .get_format_info() hook for CCS
  SKL+ display engine can scan out certain kinds of compressed surfaces
    produced by the render engine. This involved telling the display
    engine the location of the color control surfae (CCS) which
    describes which parts of the main surface are compressed and which
    are not. The location of CCS is provided by userspace as just
    another plane with its own offset.

[PATCH 4/8] drm/i915: Update format_is_yuv() to include NV12

[Vidya Srinivas]

From: Chandra Konduru <chandra.konduru@intel.com>

This patch adds NV12 to format_is_yuv() function
for sprite planes.

v2:
-Use intel_ prefix for format_is_yuv (Ville)

v3: Rebased (me)

v4: Rebased and addressed review comments from Clinton A Taylor.
	"static function in intel_sprite.c is not available
	to the primary plane functions".
	Changed commit message - function modified for
	sprite planes.

v5: Missed the Tested-by/Reviewed-by in the previous series
	Adding the same to commit message in this version.

v6: Rebased (me)

Fixed that error in this series.
Review comments from Ville (11th July 2017) addressed.

Chandra Konduru (6):
  drm/i915: Set scaler mode for NV12
  drm/i915: Update format_is_yuv() to include NV12
  drm/i915: Upscale scaler max scale for NV12
  drm/i915: Add NV12 as supported format for primary plane
  drm/i915: Add NV12 as supported format for sprite plane
  drm/i915: Add NV12 support to intel_framebuffer_init

Ville Syrjälä (2):
  drm/i915: Implement .get_format_info() hook for CCS
  SKL+ display engine can scan out certain kinds of compressed surfaces
    produced by the render engine. This involved telling the display
    engine the location of the color control surfae (CCS) which
    describes which parts of the main surface are compressed and which
    are not. The location of CCS is provided by userspace as just
    another plane with its own offset.
