7f1a113c89 drm-backend: do not skip renderer if capturing screen
The renderer must be called for any pending screen capture to complete.
Previously this was guaranteed by weston_screenshooter_shoot() forcing
full output damage, so damage was never empty. If the future,
screenshooting stops inflicting damage, and the damage on the primary
plane even after disabling hardware planes may be empty.

This patch ensures that screenshots do not get stuck until damage
occurs.

ea0b03dff0 libweston/backend/drm: might need EGL
gbm-drm.c includes gl-renderer.h. When EGL is enabled, that in turns

This condition is modelled after a similar one in libweston/meson.build

9b94a7d833 Bump libdrm dependency to 2.4.95
96bef0517e "drm-backend: add support for
writeback connectors" started using DRM_MODE_CONNECTOR_WRITEBACK and
DRM_CLIENT_CAP_WRITEBACK_CONNECTORS. These were introduced in libdrm
2.4.95.

According to
https://gitlab.freedesktop.org/wayland/weston/-/merge_requests/311
Ubunut Xenial is the only mentioned distribution that does not provide a
libdrm new enough. I think that is fine to drop now, 2016 was a good
while ago.

Libdrm 2.4.95 also introduced DRM_CLIENT_CAP_ASPECT_RATIO,
DRM_MODE_PICTURE_ASPECT_64_27, DRM_MODE_PICTURE_ASPECT_256_135.

The fallback definitions for the above are dropped.

7086396f75 drm-backend: reduce number of drmModeGetConnector() calls
Instead of calling drmModeGetConnector() in drm_head_create()
and drm_head_update_info(), it is better to call it in
drm_backend_create_heads() and drm_backend_update_heads().
Then we can pass the drmModeConnector object as parameter.
This does not change the behavior of the code, but help us
to avoid unnecessarily calling drmModeGetConnector().

Besides that, in the future we will have support for writeback
connectors. And so drm_backend_create_heads() will be reworked
to also populate a list of writeback connectors. To make this
work, we are going to need to know if a connector is of the
writeback type or not, to know if we should call drm_head_create()
or drm_writeback_create(). We can only tell the type of connector
if we have the drmModeConnector object.

e636990de3 drm-backend: move connector data from struct drm_head to struct drm_connector
This is the first step in order to add support for writeback
connector in Weston. We don't want writeback connectors data
to be stored in 'struct drm_head' objects, as these objects are
used to output content and we should not use writeback connectors
for this purpose.

The writeback connectors will be stored in a new 'struct
drm_writeback', but the connector data is common between
'struct drm_head' and 'struct drm_writeback'.

So move connector data from 'struct drm_head' to 'struct
drm_connector'. This helps to avoid code duplication and makes
the code clearer.

bb33f90658 drm-backend: free old connector props before replacing it with newer data
In commit c1e89ba2 "compositor-drm: move connector fields into
drm_head" the function drm_head_assign_connector_info() was
introduced. By that time it was being used only at drm_head
creation, and not to handle connector changes.

In d2e6242e "compositor-drm: create heads for all connectors"
it started to be used also to handle connector changes. In
this scenario we replace old connector props with newer data.
Before doing this, free the old connector data to avoid memory
leak.

Note that as drm_property_info_free() is safe to be called on
a zero-initialized struct, we can call it even in the case where
the head is being created and there are no props yet.

b00d1a2efb drm-backend: move CRTC data from struct drm_output to new struct drm_crtc
There are no 'struct drm_output' for CRTCs that are not active.
Also, CRTC data lives in 'struct drm_output'. This is causing
us some trouble, as the DRM-backend needs to program those
unnactive CRTCs to be off.

If the DRM-backend had the reference for every CRTC (being
active or not), it would make certain functions (e.g.
drm_pending_state_apply_atomic()) more simple and efficient.

Move CRTC data from 'struct drm_output' to 'struct drm_crtc',
as this is the first step to allow the DRM-backend to have
references for every CRTC.

Also, add list of CRTCs to DRM-backend object. Now the
DRM-backend is responsible for allocating/deallocating the CRTC
objects. The outputs will only reference, init and fini the CRTCs
in this list.

Initially finish_frame() was never called in drm_output_update_complete() for

However finish_frame() may now be called for repaint_status !=

5130a8c21a backend-drm: Correctly tear down the DRM backend
It seem that we skipped to put back in TEXT mode the tty, in case a DRM
device node wasn't present at that time, or it isn't present at all. This
orders the destroy part correctly as to handle that case as well.

As a side effect, as the tty will still be set to GRAPHICS mode we will
require a manual change of the tty number, which might be not possible
on all systems. Properly putting back the tty to TEXT mode should avoid
that, and allows to re-use the same tty no in case the DRM device has
been created at a later point in time.

53a71cb186 drm: Reset associated universal plane states when finalizing a crtc
When dissociating a universal plane from a crtc, we currently don't
reset the current state of the plane (plane->state_cur). When attempting
to use this plane in the future, we can run into invalid memory accesses
due to left over associations with potentially freed drm backend
objects. This commit resets the state of the scanout and cursor
universal planes associated with a crtc.

The following scenario exhibits the problem:

1. Start a (fullscreen) client that is suitable for and assigned to
   the scanout plane. The plane's state_cur->output value is set.
2. Unplug the monitor: the scanout plane is "released" but still
   maintains the state_cur->output association.
3. Replug the monitor: the plane is deemed unavailable due to an
   existing, albeit invalid, state_cur->output value. Note the memory
   errors trying to access the drm_output which was freed at step (2).

98d75e1b23 drm: Remove unnecessary condition in drm_output_render reuse
This condition inside drm_output_render() checks if we can reuse the
existing renderer buffer for the primary plane; this occurs in
mixed-mode composition where a client buffer promoted to a plane has
changed, but the primary plane is unchanged.

We accomplish this by checking if there is no damage on the
primary/renderer plane, and then if there is already a renderer buffer
active on the primary plane: in that case, we can reuse the buffer we
already have.

There was a further condition checking if the width and height were
identical. This was designed to prevent against issues on mode changes.
However, runtime mode changes are already quite broken, and a mode
change will also cause damage on the full plane. We can simply remove
this condition.

f014964f6f weston-log: rename the confusing function name weston_compositor_log_scope_destroy()
There's a function named weston_compositor_log_scope_destroy()
but it doesn't take a struct weston_compositor argument.

Rename it to weston_log_scope_destroy(), as the argument is a
struct weston_log_scope.
