Simon Ser 8e27418dd3 backend/wayland: flush remote display
It turns out wl_event_source_check is not enough to guarantee that the
remote wl_display will be flushed after we queue requests. We need to
explicitly flush, just like we do in our X11 code.

backend/x11: remove output_set_refresh
The X11 backend uses the Present extension to schedule frames. The
refresh rate is unused.

Simon Ser 73ffab70b0 backend/drm: don't blit in drm_fb_import
Instead blit in drm_plane_lock_surface. This makes drm_fb_import simpler
and better fits its name.

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.

Fixes #2670

Simon Ser 702eed5cbd backend/x11: fix region not being actually used
The region variable was shadowed in an if block. As a result, in the
outer block region was always XCB_NONE and was never destroyed (causing
a memory leak on the server).

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.

See #2659

backend/drm: fix modifiers for cursor plane buffers
In 93cd3a79b2 ("backend/drm: stop using GBM flags"), we stopped
using the GBM_BO_USE_LINEAR flag in favor of a modifier list set
to { DRM_FORMAT_MOD_LINEAR }. However, the last argument of
drm_plane_init_surface disables modifiers -- so the buffer will just
get allocated with an implicit modifier, without necessarily being
LINEAR.

To fix this, allow modifiers when allocating the cursor buffers.
wlr_drm_plane.formats should already have the necessary LINEAR
restrictions.

Simon Ser f17b0f975d backend/drm: add wlr_drm_connector_get_id
This allows a compositor to get a KMS connector object ID from a
wlr_output. The compositor can then query more information about
the connector via libdrm.

This gives more freedom to compositors and allows them to read
KMS properties that wlroots doesn't know about. For instance,
they could read the EDID or the suggested_{X,Y} properties and
change their output configuration based on that.

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.

backend/headless: create renderer after wlr_backend_init
We were calling wlr_renderer_autocreate before wlr_backend_init,

Simon Ser 9e98f497af backend/drm: use local DRM FD for wlr_rend
The new wlr_renderer_autocreate API is great for compositors, however
it causes some issues with DRM multi-GPU support.

A DRM child backend wants the compositor to use the parent GPU, so it
exposes the parent's DRM FD in get_drm_fd. However, in order to be able
to perform multi-GPU buffer copies, the child DRM backend still needs to
create a local renderer.

Use the new private wlr_renderer_autocreate_with_drm_fd function to
avoid creating a renderer for the parent GPU.

Simon Ser afdf4dc890 render/gles2: make EGL context current in bind_buffer
Instead of requiring callers to manually make the EGL context current
before binding a buffer and unsetting it after unbinding a buffer, do
it inside wlr_renderer_bind_buffer.

This hides renderer-specific implementation details inside the
wlr_renderer interface. Non-GLES2 renderers may not use EGL.
This removes all EGL dependencies from the backends.

is not NULL, current_fb->wlr_buf is guaranteed to not be NULL.

of the backends.

Simon Ser e8d56ca415 backend/session: allow wlr_session_find_gpus to return an error
Sometimes wlr_session_find_gpus will encounter an error. This is
different from finding zero GPUs.

On error, wlr_session_find_gpus already returns -1. However, this is
casted to size_t, so callers uncorrectly assume this is a success.

Instead, make wlr_session_find_gpus return a ssize_t and allow callers
to handle the error accordingly.

wlr_drm_connector.crtc may be updated by the DRM backend while a
page-flip is pending. In this case, the page-flip handler won't be able

Save the CRTC when performing a page-flip to ensure we always find the
right connector when we get the event.

Simon Ser 576ff57db0 backend/drm: ignore hotplug events while inactive
When the session is inactive, we can't change the KMS state. Ignore
hotplug events so that compositors don't try to perform a modeset when
a connector is plugged in. We already re-scan connectors when the
session becomes active.

To test, run a wlroots compositor on VT 1, switch to VT 2, unplug a
connector, re-plug it, switch back to VT 1. Without this patch the
screen is black on VT 1.
