We don't need the whole wl_display here anymore. The wl_event_loop
is enough.
|
|
The wl_display destroy listener cleans up the global (if any).
wlr_output.display will go away, so setup the listener in
wlr_output_create_global() instead of wlr_output_init().
|
|
Currently wlr_output holds a wl_display, but it will go away soon.
Instead of relying on that field in wlr_output_create_global(),
make the dependency explicit by taking a wl_display as argument.
|
|
The output layout creates and destroys wl_output globals. We will
soon need the wl_display to do so.
|
|
wl_display holds a lot more than wlr_session needs: wlr_session
only needs to wait for a FD to become readable, but wl_display
provides full access to the Wayland client and protocol objects.
Switch to wl_event_loop to better reflect the above.
|
|
|
|
This is consistent with other X11 window managers (checked against i3
and mutter).
|
|
We hand-roll this in multiple places.
|
|
These aren't really tied to wlr_output.
|
|
While the xdg-shell protocol requires this, it does not yet have
a dedicated error code for invalid titles; this commit makes
wlroots send a generic error instead.

All built-in renderers now implement the new API.

wlr_input_inhibitor.h has been marked as deprecated in 0.17.0.

When a texel from the Vulkan format VK_FORMAT_B8G8R8A8_SRGB is read,
the sRGB to linear conversion is applied independently to the R, G,
and B channels; the A channel has no influence on this. However,
DRM_FORMAT_ARGB8888 buffers are, per Wayland protocol, not encoded
in this fashion; one must first unpremultiply the color channels
before doing sRGB to linear conversion. This commit switches to
handling ARGB8888 and ABGR8888 formats using the general fragment
shader conversion from electrical to optical values.

Unfortunately we have no way to get back the proper render node in
that case. This will be fixed with [1]: with that Mesa patch, the
wlr_renderer will return the proper render node and the existing
logic will work fine.

This doesn't change functionality, both the values are the same. Less
confusing to use the box size.
|
|
|
|
Leaving this empty would have it filled in with the size of the source
texture, but we want the destination size.

drm_crtc_commit() already ensures that atomic-only flags are
disallowed.
|
|
Instead of having this condition checked in multiple places,
centralize it so that they don't go out-of-sync.
|
|
This chunk of code was moved by mistake.
Fixes: 3b53d1cbf199 ("backend/drm: introduce page-flip tracking struct")
|
|
|
|
|
|
When we destroy the backend, page flips will no longer be invoked meaning
those won't clean up the page flips for us.
|
|
|
|
Introduce a per-page-flip tracking struct passed to the kernel
when we request a page-flip event for an atomic commit. The kernel
will pass us back this pointer when delivering the event.
This eliminates any risk of mixing up events together. In particular,
if two events are pending, or if the CRTC of a connector is swapped,
we no longer blow up in the page-flip event handler.

Don't break and free event as the commont says:
wlr-xwayland will free the event.
|
|
This is important for buffers that are meant to render any sort of
text.
|
|
Helpers care about the primary output. They need to know when it changes
even if intersection status has not changed necessarily.
|
|
We want to call the outputs updated signal when an output scale or transform
changes. Otherwise helpers like the scene surface helpers will not be
notified of scale changes and not pass them to clients.
|
|
This avoids a black screen during multiple seconds on shutdown.
To fully allow for flicker-free transitions between DRM masters,
we will also need [1].

Right now this is done "by chance" because we disable all CRTCs
on shutdown. However, we'll stop doing this. Plus, if disabling
a CRTC fails, we don't cleanup properly.

We will need this later so that we can determine the subsurface tree
that owns any given scene node.
|
|
The pointers mean that we can mutate them. This will be useful later
so we can hide details from the compositor when we clip subsurface trees.

"View" has been cargo-culted from Weston. In Weston, a view is not
even necessarily a toplevel -- it's just a way to draw an arbitrary
somewhere (a surface may be painted at multiple locations
simultaneously). The Weston concept has been misunderstood and then
was carried over to rootston, Sway, and tinywl.
Let's just use the official Wayland wording instead.
|
|
It can be e.g. a popup.
