Since drm-backend requires libgbm 21.1.1 or later, there is no need to
support the old libgbm which does not support modifiers or fd import.

We seem to be using at least mesa 21.1.1 since Weston 10, but we never
explicitly asked for it.

Add libdisplay-info as a better alternative for parsing EDID. This way
we do not need to extend Weston's ad hoc parser for new things that
especially HDR support requires.
Eventually the ad hoc parser will be deleted and libdisplay-info becomes
a hard dependency for the drm-backend, reducing our maintenance burden.
Unlike the ad hoc code, libdisplay-info has automated CI testing.

If the GBM bo was allocated on a different device than the device that is used
for the fb, we have to import the fd first and update the handle.
Use drmPrimeFDToHandle directly instead of using a gbm device for the scanout
device, since a gbm device would require a gbm implementation, which is often
not available for devices that only support scanout.

Make sure dep_egl is always a valid dependency object, even if not
found. Ensure it is not found when not wanted, to avoid linking when
found but not wanted.
Using a not-found dependency in Meson is defined to be a safe no-op, so
use that to simplify the backend dependencies.
libweston/meson.build already errors out if renderer-gl is enabled and
EGL is not found, so the same checks can be removed from the backends.

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.

Forward the HDR Static Metadata Type 1 to the video sink. This makes the
sink aware of our video content parameters and may be able to produce a
better picture. This type of metadata is used only with the ST 2084 HDR
mode a.k.a PQ.

This creates a new file for KMS related color code, to avoid making
drm.c even longer.
The moved code was just added in 5151f9fe9e

These are fallback definitions in case libdrm is not new enough.
They are copied from libdrm 2.4.107.
struct hdr_output_metadata defines the contents of the blob to be used
with the connector property "HDR_OUTPUT_METADATA".
This is needed for programming a HDR mode in KMS.
This headers need to be excluded from Doxygen, because Doxygen chokes on
the kerneldoc markup.

gbm-drm.c includes gl-renderer.h. When EGL is enabled, that in turns
includes egl.h. As such, dependencies for drm should include EGL if
it is available.
This condition is modelled after a similar one in libweston/meson.build

The pipewire plugin uses this API as well, not just the remoting plugin. So
enable it if either is enabled.
And disable pipewire in the no-gl-renderer CI build. The virtual outputs don't
work without it.

Since commit 28d26483 ("build: bump libdrm requirement to newer version
(2.4.83)"), all supported libdrm versions provide modifier formats,
atomic API and blob formats. Remove ifdef checks (HAVE_DRM_ADDFB2_MODIFIERS,
HAVE_DRM_ATOMIC, HAVE_DRM_FORMATS_BLOB) to improve the code and make it
simpler.

Make GBM optional in case GL renderer is disabled. This allows to
build Weston with DRM backend without Mesa dependencies.
Signed-off-by: Stefan Agner <stefan@agner.ch>
Move DRM virtual support into a separate file. Use the remoting
compile time option to disable DRM virtual support since this is the
only user of DRM virtual support currently. This will make it easier
to build the DRM backend without GBM support.

In the future libweston will stop providing it for its users, since it's not
part of libweston API.
Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.com>
We have two kinds of libweston users: internal and external. Weston, the
frontend, counts as an external user, and should not have access to libweston
private headers. The shell plugins are external users as well, because we
intend people to be able to write them. Renderers, backends, and some plugins
are internal users who will need access to private headers.
Create two different Meson dependency objects, one for each kind.
This makes it less likely to accidentally use a private header.
Screen-share is a Weston plugin and therefore counts as an external user, but
it needs the backend API to deliver input. Until we are comfortable exposing
public API for that purpose, let it use internal headers.

Define common_inc which includes both public_inc and the project root directory.
The project root directory will allow access to config.h and all the shared/
headers.
Replacing all custom '.', '..', '../..', '../shared' etc. include paths with
common_inc reduces clutter in the target definitions and enforces the common
#include directive style, as e.g. including shared/ headers without the
subdirectory name no longer works.
Unfortunately this does not prevent one from using private libweston headers
with the usual include pattern for public headers.

drm_assign_planes() is called to separate views out and decide what will
be taken out for plane composition and what will be left for the
renderer to compose.
It calls drm_output_propose_state() in order to find a good
configuration, which itself has a number of helpers that it calls. Break
these out into a separate file.

Move the DRM-backend into a new sub-directory to make it stand out from
libweston core. This facilitates splitting drm.c into more files later.
