"max bpc" property is meant for working around faulty sink hardware.
Normally it should be set to the maximum possible value so that the
kernel driver has full freedom to choose the link bpc without being
artificially forced to lower color precision.
The default value is 16 because that is a nice round number and more
than any link technology I've heard is using today which would be 12.
Also offer an API set the value, so that weston.ini could be used in the
next patch for sink workaround purposes.

This is a follow-up change of b623fd2a ("drm-backend: stop parsing IN_FORMATS

2.4.108, clean up remaining and unnecessary conditional code. Change 69140640

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.

This patch makes sure we have a gl_buffer_state present when using

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.

This is the beginnings of creating composited content HDR metadata for
the ST2084 HDR mode. The immediate goal is to allow essentially setting
the HDR metadata from weston.ini, so that it can be experimented with.
Setting an output ICC profile will stop weston.ini metadata from taking
effect, but using an ICC profile in HDR mode is an open question anyway.
maxDML, maxCLL, and minDML are set based on the assumption that we want
to make use of the full sink/monitor dynamic range.

basic output color characteristics, and HDR metadata. Implementing these

This adds color_chracteristics field in weston_output. This field is

Color managers can use this information when choosing the output color
space and dynamic range, particularly when no ICC profile has been set.
This is most useful for HDR outputs, where the HDR static metadata for
PQ mode or the display luminance parameters for HLG mode can be based on
color_characteristics.
The fields of weston_color_characteristics mirror the information
available in EDID. However, using EDID information as-is has several
caveats, so the decision to use EDID for this is left for the frontend
and ultimately to the end user.

SHM buffers are special, in that we don't keep individual copies of them
within the GL renderer. Instead, the GL surface has a texture allocated
