Simon Ser 46c42e55c6 backend/drm: add support for FB_DAMAGE_CLIPS
This allows the kernel to access our buffer damage. Some drivers
can take advantage of this, e.g. for PSR2 panels (Panel Self
Refresh) or for transfer over USB.

Closes: https://github.com/swaywm/wlroots/issues/1267

Simon Ser c55f70c8b7 backend/drm: stop initializing renderer for parent backend
Unless we're dealing with a multi-GPU setup and the backend being
initialized is secondary, we don't need a renderer nor an allocator.
Stop initializing these.

We can't nuke it completely, we still need it for multi-GPU.

Simon Ser cc8bc0db20 backend/drm: stop restoring CRTCs on exit
This is the cause of the spurious "drmHandleEvent failed" messages
at exit. restore_drm_outputs calls handle_drm_event in a loop without
checking whether the FD is readable, so drmHandleEvent ends up with a
short read (0 bytes) and returns an error.

The loop's goal is to wait for all queued page-flip events to complete,
to allow drmModeSetCrtc calls to succeed without EBUSY. The
drmModeSetCrtc calls are supposed to restore whatever KMS state we were
started with. But it's not clear from my PoV that restoring the KMS
state on exit is desirable.

KMS clients are supposed to save and restore the (full) KMS state on VT
switch, but not on exit. Leaving our KMS state on exit avoids unnecessary
modesets and allows flicker-free transitions between clients. See [1]
for more details, and note that with Pekka we've concluded that a new
flag to reset some KMS props to their default value on compositor
start-up is the best way forward. As a side note, Weston doesn't restore
the CRTC by does disable the cursor plane on exit (see
drm_output_deinit_planes, I still think disabling the cursor plane
shouldn't be necessary on exit).

Additionally, restore_drm_outputs only a subset of the KMS state.
Gamma and other atomic properties aren't accounted for. If the previous
KMS client had some outputs disabled, restore_drm_outputs would restore
a garbage mode.

Simon Ser aec062d0d3 backend/headless: remove wlr_output_impl.export_dmabuf
This is now provided by the generic wlr_output implementation.

Simon Ser 017555651b backend/drm: add test_only arg to wlr_drm_interface.crtc_commit
Right now callers of drm_crtc_commit need to check whether the
interface is legacy or atomic before passing the TEST_ONLY flag.
Additionally, the fallbacks for legacy are in-place in the common
code.

Add a test_only arg to the crtc_commit hook. This way, there's no
risk to pass atomic-only flags to the legacy function (add an assert
to ensure this) and all of the legacy-specific logic can be put back
into legacy.c (done in next commit).

Simon Ser a670ee7940 backend/x11: remove swapchain
Rely on wlr_output's generic swapchain handling.

We still need a renderer for cursor readback, sadly.

Simon Ser 44feb832f9 backend/headless: remove swapchain
Rely on wlr_output's generic swapchain support instead of creating our
own. The headless output now simply keeps a reference to the front buffer
and does nothing else.

Simon Ser b86a0c8d8f backend/drm: move cursor fields to wlr_drm_connector
Doesn't make a lot of sense to split the cursor fields between
wlr_drm_plane and wlr_drm_connector. Let's just move everything to
wlr_drm_connector.

Simon Ser 2b0a1aeed5 output: take a wlr_buffer in set_cursor
Instead of passing a wlr_texture to the backend, directly pass a
wlr_buffer. Use get_cursor_size and get_cursor_formats to create
a wlr_buffer that can be used as a cursor.

We don't want to pass a wlr_texture because we want to remove as
many rendering bits from the backend as possible.

Simon Ser c82f37542d backend/headless: use common renderer and allocator
Instead of managing our own renderer and allocator, let the common
code do it.

Because wlr_headless_backend_create_with_renderer needs to re-use
the parent renderer, we have to hand-roll some of the renderer
initialization.

Simon Ser a1e8a639b3 backend/drm: introduce drm_connector_commit_state
Backend-initiated mode changes can use this function instead of
going through drm_connector_set_mode. drm_connector_set_mode becomes
a mere drm_connector_commit_state helper.

Simon Ser 218955ce95 backend/drm: remove mode arg from drm_connector_set_mode

Simon Ser 31082a0554 backend/drm: remove wlr_drm_crtc_state.mode

Simon Ser dfea0ff31d backend/drm: remove wlr_drm_crtc_state.active
Replace it with drm_connector_state_active, which figures out
whether the connector is active depending on the wlr_output_state
to be applied.

Simon Ser 485ecc11a6 backend/drm: remove wlr_drm_crtc.pending_modeset
Replace it with a new drm_connector_state_is_modeset function that
decides whether a modeset is necessary directly from the
wlr_output_state which is going to be applied.

Simon Ser 1a9701cd7c backend/drm: take wlr_output_state as arg in commit callers
Instead of relying on wlr_output.pending to be empty when performing
backend-initiated CRTC commits, use a zero wlr_output_state.

Simon Ser 8f90d7f8f5 backend/drm: take wlr_output_state as arg in crtc_commit
Stop assuming that the state to be applied is in output->pending in
crtc_commit. This will allow us to remove ephemeral fields in
wlr_drm_crtc, which are used scratch fields to stash temporary
per-commit data.

Kenny Levinsen 7f09085461 backend/session: Remove session_impl
libseat provides all session functionality, so there is no longer need
for a session backend abstraction. The libseat device ID, seat handle
and event loop handle are moved to the main wlr_session and wlr_device
structs.

Roman Gilg b36af22c94 backend: move get_drm_fd to public interface
The get_drm_fd was made available in an internal header with a53ab146f. Move it
now to the public header so consumers opting in to the unstable interfaces can
make use of it.

Simon Ser 1eb38e0015 Remove WLR_HAS_XCB_ERRORS
wlroots' dependency on this library doesn't change the features
exposed to compositors. It's purely a wlroots implementation detail.
Thus downstream compositors shouldn't really care about it.

Introduce an "internal_features" dictionary to store the status of
such internal dependencies.

zccrs e76583f1ad Use absolute paths in include in header files
To unify the code style of the project, absolute paths have been used in
some places, such as '#include "render/allocator.h"' in
"render/gbm_allocator.h". Except for include the wayland protocol
headers should be consistent.

Ilia Mirkin 7bc8dbb991 backend/x11: keep track of exposed rects, add them to damage regions
When we receive an Expose event, that means that we must redraw that
region of the X11 window. Keep track of these regions with pixman
regions, and merge them with the additional output damaged regions.

Ilia Mirkin 966e653935 backend/x11: set a blank cursor rather than hiding globally
This actually simplifies the logic since we no longer have to wait for
enter/leave events, and also improves the UX when e.g. handling a crash
with gdb attached.

Simon Ser cb6f584496 backend/drm: add support for the subconnector property
The subconnector property indicates the connector sub-type. This is
useful because that usually indicates what kind of connector the user
has plugged in to their monitor, e.g. a DisplayPort-to-DVI cable will
indicate a DVI subconnector. Also some laptops have non-DP connectors
that are internally linked to a DP port on the GPU.

Set the output description accordingly.
