This reverts commit 6914064066.
This is a follow-up change of b623fd2a ("drm-backend: stop parsing IN_FORMATS
blobs, use libdrm instead"). Weston now has a hard-requirement on libdrm
2.4.108, clean up remaining and unnecessary conditional code. Change 69140640
("backend-drm: add HDR_OUTPUT_METADATA definitions") is no longer needed
and stop including libdrm-updates.h from kms-color.c.

Before this change the drm-backend in Weston did the work of parsing DRM
blobs in order to query IN_FORMATS data, if available. This is also the
case for other DRM/KMS clients that use IN_FORMATS (i.e. X).
libdrm 2.4.108 with e641e2a6 ("xf86drm: add iterator API for DRM/KMS
IN_FORMATS blobs") introduced a dedicated API for querying IN_FORMATS data.
Bump the minimum required version to 2.4.108, stop parsing IN_FORMATS in
Weston and start using DRM iterators. In addition, remove fallback code for
libdrm <2.4.107.

libdrm with version 2.4.108 provides new functionality for parsing
IN_FORMATS blobs. Weston can make use of it and avoid implementing
its own logic. At present CI uses Debian 11 (bullseye) which comes
with an older version (2.4.104), so we build it from source.

This patch makes sure we have a gl_buffer_state present when using
direct-display protocol extensions (which forbids any GL imports, and
assumes a direct path with the display unit to perform a KMS import).
Without this patch we would basically have no gl_buffer_state at repaint
time because we never manged to create one, as direct-display code path
will return much early.

Added cLUT profile creation to validate linearization algorithm
for DToB3 tag (direction dev to PCS). The 3DLUT is
built by using raw matrix conversion from dev to XYZ and reverse
(XYZ to device).
The test uses floating point pipeline, known as unbounded mode of LCMS.
The details are described in ICCSpecRevision_02_11_06_Float.pdf
The purpose of these new test cases is to keep the GL-renderer 3D LUT
path tested even after color-lcms and GL-renderer start using
specialized matrix-shaper paths.
These also exercise build_eotf_from_clut_profile() in color-lcms, but do
not actually verify it. These cases only test that the recovered EOTF
and its inverse produce an identity mapping together.
BT.2020 is not used in these tests, because the RGB-XYZ conversion
matrix does not stay inside [0.0, 1.0] in either direction, which would
be a problem for the 3D LUT element in the multiProcessingElement
pipelines. Handling that would have been possible, but testing with
AdobeRGB color space should suffice while keeping the test code from
being even more complicated.
roundtrip_verification() tests that we succeed in creating cms
pipelines correctly in both directions so that the resulting ICC file is
better behaved. The Weston test itself only cares about the BToD
direction.

We will want to run the same color spaces with different types of ICC
profiles. To help with that:
1. Let struct lcms_pipeline define the test color space and
transformations and move the tolerance into a new per test case
structure.
2. Added profile type: PTYPE_MATRIX_SHAPER, PTYPE_CLUT.
PTYPE_MATRIX_SHAPER is the previously implemented type.

This adds a new test helper library that depends on LittleCMS 2.
For starters, the library implements conversion from enum transfer_fn to
ICC multiProcessingElements compatible LittleCMS curve object.
That conversion allows encoding transfer funtions in ICC files and
LittleCMS pipelines with full float32 precision instead of forcing a
conversion to a 1D LUT which for power-type curves is surprisingly
imprecise.
This also adds CI tests to make sure the conversion matches our
hand-coded transfer functions.

When color management is disabled, the fragment shader was still first
ensuring straight alpha and then immediately just going back to
pre-multiplied. This is near-impossible for a shader compiler to
optimize out, I guess because of the if-statement to handle division by
zero. Having view alpha applied in between certainly didn't make it
easier.
That causes extra fragment computations that are unnecessary. In the
issue report this was found to cause a notable performance regression.
Fix the performance regression by introducing special-case paths for
when straight alpha is not needed. This skips the unnecessary
computations.

Currently, the opaque is discarded for all transformations other than a simple
translation, because correctly transforming the opaque area is not possible in
general.
However, there is one simple case that is probably the most common one: A fully
opaque surface that is translated and scaled. In this case the opaque area is
simply the new bounding box. So set the transformed opaque area accordingly.
Signed-off-by: Michael Olbrich <m.olbrich@pengutronix.de>
If surface->is_opaque is set then we can assume that the whole surface is
opaque. In the trivial case (no transformation or translation only) this means
that transform.boundingbox is exactly the view area and is fully opaque. So it
can be used for transform.opaque.
This is important because damage calculation uses transform.opaque. Without
this, anything underneath a surface without an explicit opaque region but a
pixel format without alpha channel is drawn unnecessarily.
