00b74293e8 backend-drm: use pixel format to print gbm format
The gbm_format is the same as the drm format used by the pixel format.

Print the format name using the pixel format in the error message to make the
error message easier to understand for humans.

83d1eafd81 backend-drm: virtual: use the DRM fd from the fb
The fb already contains a DRM fd for later use. So just use that one instead of
fetching it from the backend.

This is necessary if the fbs are allocated on different devices, since otherwise
the wrong device might be used to get the fd of the passed fb.

Besides that, it can place a fullscreen state of simple-egl on the

7412a01437 backend-drm: Retrieve reason if dmabuf import failed
As we could have situations where dmabuf import failed when attempting
to figure it the framebuffer is scanout-capable, make sure we also have
a way to store that information. Otherwise, we could end up
NULL-dereferencing, as we don't provide a valid storage for it.

Further more, with this, we also print out the reason why it failed, to
aid in further debugging.

Observed on platforms where GBM_BO_HANDLE failed + in combination w/

8ebebb20ef drm-backend: add color_outcome / HDR metadata serial
Output color profile may be changed in flight. Output basic color
characteristics and EOTF mode cannot yet be changed in flight, but it is
reasonable to assume they could in the future. Therefore the color
outcome data may change in flight as well, which is the basis for HDR
metadata, which needs to be updated as well.

Track the changes to color outcome data with a serial number.
DRM-backend checks the serial number to see if it needs to re-create the
HDR metadata blob. This allows the changes to propagate all the way to
KMS.

The code added here is more of a reminder of what should happen than a
tested path.

e6a9e3c4ee backend-drm: default to XRGB2101010 for HDR
Trying to do HDR with XRGB8888 is a bit like using RGB565 on SDR: you
get visible color quantization and banding in gradients (without dithering
which Weston does not implement yet, and might not work too well for HDR
anyway).

Therefore, on any HDR mode, default output framebuffer format to 10 bpc
instead of 8 bpc.

Ideally we'd also optionally try 16F or 16 bpc formats, but automatic
fallbacks for those are more complicated to arrange. You can still
configure 16F or 16 bpc manually.

This patch also moves the default format setting from
drm_output_set_gbm_format() to drm_output_enable(), because setting the
default now requires eotf_mode. Frontends may call set_gbm_format()
first and set eotf_mode next. This does create an awkward situation for
outputs that a frontend disables and re-enables. This patch here makes
sure that the old output configuration remains, but changing eotf_mode
may not change the default format. One needs to call
set_gbm_format(NULL) to re-evaluate the default format. Resetting the
format on drm_output_deinit() would lose the current setting.

DRM_FORMAT_INVALID was introduced in libdrm 2.4.95 which we already
hard-depend on.

5151f9fe9e backend-drm: program HDR_OUTPUT_METADATA
Program the connector property HDR_OUTPUT_METADATA based on the EOTF
mode of the output.

For now, this changes only the EOTF. The colorimetry and luminance are
left undefined, to be filled in by later patches. This should still be
enough to put a video sink into HDR mode, albeit the response is
probably unknown.

drm_output keeps track of the currently existing blob id. If the blob
contents need to be re-created, this blob would be destroyed and the
field set to zero. In this patch, there is no provision for runtime
changing of HDR metadata, so there is no code doing that.

Destroying the blob at arbitrary times is not a problem, because the
kernel keeps a reference to the data as long as the blob id remains with
KMS.

6ee6e76a0c compositor: remove repaint_data from compositor
The repaint_data is entirely backend specific. Moreover, it is only used by the
drm backend, while other backends ignore the repaint data.

There will always be only one repaint active, thus, there is no need to pass the
repaint data from the outside.

The repaint_data breaks with the multi-backend series, which calls repaint begin
for all backends to get the repaint_data. The repaint_data of the last backend
will then be passed to all other backend. At the moment, this works, because the
drm backend is the only backend that implements the begin_repaint call.

Another option would be to track the repaint data per backend in the compositor,
but actually, it the backend needs to track state across the calls, it's its own
responsibility.

81e74ff334 backend-drm: Don't take buffer-release reference for cursor views
We just copy the SHM buffer straight into a separately-allocated GBM BO,
so no need to take a reference on the buffer itself or keep it from
being released.

All drm_output_try_view_on_plane really does at this point is to call
the prepare_*_view function for the requisite plane type, and take a ref
on the weston_buffer from the client. Given that we don't need to keep
the client buffer alive, we can short-circuit
drm_output_try_view_on_plane, and instead just call
drm_output_prepare_cursor_view directly when we have a cursor plane.

This also makes it easier to just remove drm_output_try_view_on_plane in
following patches when we merge the overlay/scanout plane path into one.
Doing so gives us two clearly-separated paths: one for copying a SHM
client buffer into a cursor, and another for directly scanning out
client content.
