To retrieve the formats, an allocated crtc is required. If there is no
currently no crtc available, try to allocate it. This reproducable by
having a disabled output and going through a suspend cycle with amdgpu.
On start CRTCs look like this:

where the primary format can't be queried since there is no crtc
allocated for the connector. Allocating the connector inside
drm_connector_get_primary_formats() fixes this issue. This is possible
since the only user of get_primary_formats() is the swapchain allocation
function, which is only called on output enable. Do the same thing for
the cursor formats in case the user queries them before the output is
enabled.
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.

If a subsurface is being placed below a subsurface right above it, this
should be a noop. However, `node` pointed to the subsurface that was
moved, which resulted in `subsurface->parent_pending_link` being
inserted into itself, breaking parent's pending subsurface list.
This commit separates finding the requested node and getting it's `prev`
field, fixing the issue.
This reverts commit 85757665e6.
We now check if the output is enabled within wlr_output_send_frame, no
need to handle this explicitly in the DRM backend. This also fixes a
race which was introduced with this commit: if we schedule the flip,
disable and commit the output before the flip happens,
output.frame_pending will not be reset to false. We than always fail to
enable the output subsequently:

Fixes https://github.com/swaywm/wlroots/issues/3109
Similar to commit 85757665e6 ("backend/drm: Check if output is enabled
before sending frame event"), check if the output is still enabled
before sending the frame event. This fixes the bug not only for the DRM
backend, but for wayland and X11 as well.
The protocol specifies that all requests (aside from destroy) are
ignored after the compositor sends the closed event. Therefore,
destroying the wlroots object and rendering the resource inert
when sending the closed event keeps things simpler for wlroots and
compositors.
This wlr_surface_state field was a special case because we don't
want to save the whole current state: for instance, the wlr_buffer
must not be saved or else wouldn't get released soon enough.
Let's just inline the state fields we need instead.
wl_fixed_t is a 32-bit data type, but our doubles are 64-bit. This meant
that two doubles that would map to the same wl_fixed_t could compare
unequal, and send a duplicate motion event.
Refs swaywm/sway#4632.
The protocol allows compositors to not send any keymap to Wayland
clients. Handle a keymap-less keyboard correctly by sending
WL_KEYBOARD_KEYMAP_FORMAT_NO_KEYMAP instead of erroring out in the
mmap call.
When testing a modeset, make sure the caller has also provided a
buffer. This allows df0e75ba05 ("output: try skipping buffer
allocation if the backend allows it") to work as expected with the
DRM backend.
Closes: https://github.com/swaywm/wlroots/issues/3086
When enabling an output, skip the empty buffer allocation if the
backend accepts modesets without a buffer.
This fixes mode-setting with the noop backend.
According to the viewport protocol, upon wp_viewport::destroy():
> The associated wl_surface's crop and scale state is removed.
> The change is applied on the next wl_surface.commit.
Therefore, wp_viewport_destroy(viewport) should remove all viewport state.
Currently, wlroots does not remove the crop and scale state. Instead, a
client must do:
wl_fixed_t clear = wl_fixed_from_int(-1);
wp_viewport_set_source(viewport, clear, clear, clear, clear);
wp_viewport_set_destination(viewport, -1, -1);
wp_viewport_destroy(viewport);
This commit adds the necessary logic into viewport_destroy and makes
wlroots comply with the protocol.
The half-float formats depend on GL_OES_texture_half_float_linear,
not just the GL_OES_texture_half_float extension, because the latter
does not include support for linear magni/minification filters.
The new 2101010 and 16161616F formats are only available on little-
endian builds, since their gl_types are larger than a byte and thus
endianness dependent.
