Simon Ser e77c046cf9 backend/drm: fix stack overflow in dealloc_crtc
Call drm_crtc_commit directly instead of calling drm_connector_set_mode.
This restores the previous behaviour where conn_enable was called [1].

Simon Ser a3ba82885c render: choose DMA-BUF texture target via eglQueryDmaBufModifiersEXT
EGL_EXT_image_dma_buf_import_modifiers tells us whether we should use
GL_TEXTURE_2D or GL_TEXTURE_EXTERNAL_OES. Using the right texture target
can fix some failures and/or improve performance on some drivers.

This does the same as a Weston commit [1].

Tudor Brindus dc13bb827d util: fix and move `get_current_time_msec` into a util file
This commit makes `get_current_time_msec` correctly return milliseconds
as opposed to microseconds. It also considers the value of `tv_sec`, so
we don't lose occasionally go back in time by one second. Finally, the
function is moved into `util/time.cc` so that it can be reused elsewhere
without having to consider these pitfalls.

Thomas Hebb dcae6f1431 Allow keyboard and pointer grabs to hook clear_focus()
This is necessary for some grabs, which currently have no way of knowing
when the pointer/keyboard focus has left a surface. For example, without
this, a drag-and-drop grab can erroneously drop into a window that the
cursor is no longer over.

This is the plumbing needed to properly fix swaywm/sway#5220. The
existing fix, swaywm/sway#5222, relies on every grab's `enter()` hook
allowing a `NULL` surface. This is not guaranteed by the API and, in
fact, is not the case for the xdg-shell popup grab and results in a
crash when the cursor leaves a surface and does not immediately enter
another one while a popup is open (#2161).

This fix also adds an assertion to wlr_seat_pointer_notify_enter() that
ensures it's never called with a `NULL` surface. This will make Sway
crash much more until it fixes its usage of the API, so we should land
this at the same time as a fix in Sway (which I haven't posted yet).

Thomas Hebb 8bf9f5bb8b wlr_seat: Clarify wording of non-grab-respecting function comments
I found the previous wording a bit confusing when I first read it.
Reword these comments to explicitly say that the grab-respecting
variants should be used in most cases.

This change has no functional effect.

Thomas Hebb e8c00e918a wlr_seat: Declare functions in the same order for pointer, keyboard, and touch
These three APIs are very similar to one another, but they all had
slightly different function orderings. For consistency, always declare
the non_`notify` functions first, then the `notify` functions, then
`{start,end,has}_grab`.

This change has no functional effect.

Simon Ser e91417ea8d render: stop making EGL context current in wlr_egl_init
This leaves an EGL context current behind. wlr_gles2_renderer_create was

Simon Ser 019fe8bb7e backend/wayland: fix spurious eglSwapBuffers failures
This was introduced in [1]. However after reverting that PR I still
can't reproduce the bug the PR aimed to fix [2].

before resizing, let's just revert the PR.

Simon Ser b03eebf7d4 backend/drm: always perform a CRTC commit in drm_connector_commit
When the mode, status or buffer hasn't changed, drm_connector_commit was
a no-op. Because of this individual changes to the gamma LUT or adaptive
sync status were ignored (if committed without a buffer).

Instead, perform a commit to apply the changes.

Brian Ashworth 32148808ad wlr_keyboard_group: introduce enter and leave
This introduces the enter and leave events for wlr_keyboard_group.

The enter event is emitted when a keyboard is added to the group while a
key is pressed that is not pressed by any other keyboard in the group.
The data is a wl_array of the pressed key codes unique to the keyboard
that should now be considered pressed.

Similarly the leave event is emitted when a keyboard is removed from the
group while at least one key is pressed that is not pressed by any other
keyboard in the group. The data is a wl_array of the pressed key codes
unique to the keyboard that should now be considered released.

The purpose of these events are to allow the compositor to update its
state to avoid corruption. Additionally, for the leave event, the
focused surface may have been notified of a key press for some or all of
the key codes and needs to be notified of a key release to avoid state
corruption.

These were previously emitted as normal key events, but they are not
normal key events. There is no actual key press or release associated
with the events. It's purely for state keeping purposes. Emitting them
as separate events allows the compositor to handle them differently.
Since these are purely for state keeping purposes and are not associated
with an actual key being pressed or released, bindings should not be
triggered as a result of these events.

Kenny Levinsen 5e0ef70cc0 seat: Create inert objects for missing capabilities
We should throw a protocol error if the relevant capability has never

This follows the spec, and avoids possible races with the client when
capabilities are lost.

Simon Ser 15d8f1806e backend/drm: introduce pending and current CRTC state
Previously, we only had the pending state (crtc->pending, crtc->mode and
crtc->active). This causes issues when a commit fails: the pending state
is left as-is, and the next commit may read stale data from it.

This will also cause issues when implementing test-only commits: we need
to rollback the pending CRTC state after a test-only commit.

Introduce separate pending and current CRTC states. Properly update the
current state after a commit.

Simon Ser d6cc718472 backend/drm: nuke retry_pageflip
retry_pageflip is now dead code, since drm_connector_start_renderer
isn't called anymore. It was previously called when enabling an output.
The name "retry_pageflip" was a little confusing because the function
retried a modeset and the timer wasn't set up while performing a simple
page-flip.

Let's just remove this altogether for now. We can discuss whether it's
worth it to bring it back. Should we only do it on failed page-flips?
Should we only do it on EBUSY?

Tudor Brindus 0758a4fc9d xwayland: send focus change event unconditionally
This fixes issues with (at least) dialogs in Jetbrains IDEs becoming
unclickable if they ever lost focus (ref. swaywm/sway#5373). Prior to
this change, since `xwm->focus_surface` would be set prior to
`xwm_surface_activate` being called, the latter would short-circuit
immediately and not notify the application of the focus change.

Simon Ser af2f69e6c1 render/egl: unset current context after swapping buffers
After swapping buffers, it doesn't make sense to perform more rendering

This commit makes it so the context is always only current between
wlr_egl_make_current and wlr_egl_swap_buffers.

This is an alternative to [1].
