397e66a4dd backend-drm: allow more formats with pixman-renderer
Clean up the code a little by dropping the now unnecessary switch case
in drm_output_init_pixman(). As a side effect, this enables all formats
that have a pixman_format entry in the pixel format table:

  - rgb565
  - xrgb8888
  - argb8888
  - xbgr8888
  - abgr8888
  - rgbx8888

4d96635a3f pixman-renderer: track damage in weston_renderbuffer
Add a damage region to struct weston_renderbuffer and use it to replace
the previous_damage tracking in the drm backend.

Keep renderbuffers on a list in struct pixman_output_state and use it
to accumulate damage on all renderbuffers during repaint_output.
Now renderbuffers have to be created when pixman output state already
exists.
Reorder renderer output state and renderbuffer creation accordingly.

With this, pixman_renderer_output_set_hw_extra_damage() can be removed.

This can not yet replace the external damage tracking in the VNC
backend, which needsto know the accumulated damage that is not returned
from repaint_output.

debfeb3049 backend-drm: reset CRTC_GAMMA_LUT
We are assuming that CRTC_GAMMA_LUT is pass-through, so better ensure it
really is pass-through rather than whatever the previous KMS client left
there.

Unfortunately, we have old drm_output_set_gamma() API that cms-static
and cms-colord plugins are using. To avoid trampling over them, do not
touch gamma after they did. Those plugins are deprecated, so there is no
reason to make set_gamma work through atomic.

drm_output_set_gamma() is called from weston_compositor_add_output()
through the output_created_signal. This is after drm_output_enable() and
before any KMS modeset or atomic commit on the CRTC. Therefore it is not
possible that there would be any KMS action in flight when
drm_output_set_gamma() is called, and so setting deprecated_gamma_is_set
should be non-racy - like setting CRTC_GAMMA_LUT itself.

3700c78131 libweston: implement new screenshooting protocol base
This implements the basics of the new screenshooting protocol. The
actual pixel operations will be implemented separately in the renderers
and DRM-backend.

See the previous commit "protocol: new screenshooter protocol" for why.

If DRM-backend needs more from weston_capture_task when it implements
writeback screenshooting, it will be easy to add user_data or expose
weston_capture_task::link for the backend to use. Those were not added
yet because it is uncertain what is actually needed.

The DRM-backend no-damage optimization requires special handling here as
well. See also 7f1a113c89 .

f3bed68100 backend-drm: do not print head info twice
Before this patch, when a new head is found its information is printed
first as "updated" and then as "found" in the log.

The reason is that drm_head_create() calls drm_head_update_info() which
printed the head as "changed". Then drm_head_create() itself prints it
as "found".

This fixes it to print only once as "found".

3240ccc69d Don't change the max_bpc connector prop if mode=current.
As things are, even when mode=current is specified on the .ini file,
a full modeset is needed (and done), which causes a very noticeable
screen blinking. That is because setting the max_bpc on a connector
needs full modesetting.
The idea here is that if mode=current on the .ini, no modesetting
should be done, so the current max_bpc is programmed into the
connector.
But if a custom max-bpc=... is specified, that will be used instead,
even if mode=current on the .ini

4cde507be6 backend-drm: fix plane sorting
The planes in the plane_list must be sorted from largest zpos_max to smallest.

Currently the plane order is only correct when the planes are already ordered
and added starting with the smallest zpos_max. This works accidentally in most
cases because the primary plane is usually first and there is often only one
overlay plane or the zpos is sufficiantly configurable.

To fix this, insert a new plane before the first plane with a smaller zpos_max.
And if none is found, insert it at the end of the list.

3b3fdc52c3 backend-drm: improve atomic commit failure handling
When an atomic commit fails then the output will be stuck in
REPAINT_AWAITING_COMPLETION state. It is waiting for a vblank event that was
never scheduled.
If the error is EBUSY then it can be expected to be a transient error. So
propagate the error and schedule a new repaint in the core compositor.

This is necessary because there are some circumstances when the commit can fail
unexpectedly:
- With 'state_invalid == true' one commit will disable all planes. If another
  commit for a different output is triggered immediately afterwards, then this
  commit can temporarily fail with EBUSY because it tries to use the same
  planes.
- At least with i915, if one commit enables an output then a second commit for a
  different output immediately afterwards can temporarily fail with EBUSY. This
  is probably caused by some hardware interdependency.

f5a4fb5abc backend-drm: make sure all buffers are released when an output is removed
When an output is destroyed then the output state is freed immediately. In this
case, the plane state is only partially destroyed because it is the currently
active state. This includes the buffer reference.

Without the output, the plane will not be updated any more until it is used by a
different output (if possible) or the output returns and the plane is used
again.
As a result, the buffer reference is kept for a long time. This will cause some
applications to stall because weston now keeps two buffers (the one here and
another one for a different output where the application is now displayed).

To avoid this, do a synchronous commit that disables the output. The output
needs to be disabled anyways and this way the current state contains no
buffers that would remain.

`device->state_invalid = true` in drm_output_detach_crtc() is no longer
needed, because drm_output_detach_crtc() is called only when initialization
failed and the crtc was not yet used or in drm_output_deinit() when the
crtc was already disabled with the new synchronous commit.

0d3e438d08 build: fix possible race/error for some backends
There is missing dependency on linux-dmabuf-unstable-v1-server-protocol.h
header file in backend-headless, backend-drm and backend-x11. That files
do not depend on that header, in fact. But by this moment they've had
that implicit dependency due to linux-dmabuf.h header.

With specific set of meson configure options the protocol header is not
generated at the right time, what causes build error in 100% cases using
small amount of building threads (from -j1 to -j8).

d24adbbe25 backend-drm: set connector max bpc
"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.

libdrm 2.4.108 with e641e2a6 ("xf86drm: add iterator API for DRM/KMS

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
