The set_cursor() hook is a little bit special: it's not really
synchronized to commit() or test(). Once set_cursor() returns true,
the new cursor is part of the current state.
This fixes a state where wlr_drm_connector.cursor_enabled is true
but there is no FB available. This is triggered by set_cursor()
followed by a failed commit(), which resets pending_fb.
We should definitely fix the output interface to make the cursor part
of the pending state, but that's a more involved change.
|
|
Instead, call drm_connector_set_pending_fb.
|
|
The other caller (drm_connector_commit_state) already checks this.
|
|
This will be used in drm_connector_test shortly.
|
|
We can't perform a test-only atomic commit if the connector is
missing a CRTC.
|
|
drm_connector_set_pending_fb needs a CRTC to import the buffer.
|
|
This function allocates a CRTC for a connector if necessary.
|
|
Set the plane's pending FB before calling drm_connector_set_mode.
|
|
Instead of trying to perform a real modeset in init_renderer,
perform an atomic test-only commit to find out whether disabling
modifiers is necessary because of bandwidth limitations.
This decouples init_renderer from the actual commit, making it
possible to modeset an output with a user-supplied buffer instead
of a black frame.
We loose the ability to make sure the buffers coming from the
swapchain will work fine when using the legacy interface. This
can break i915 when atomic is disabled and modifiers enabled.
But i915 always has atomic (so the user must explicitly disable it
to run into potential bandwidth limitations) and is the only known
problematic driver.
|
|
Make it clear this function is a private wlroots API and will stay
that way.
|
|
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.
|
|
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.
|
|
This is a new helper function to pick a render format suitable for
a plane.
The next commit will use it to initialize the cursor multi-GPU
surface.
|
|
This was always set to ARGB8888.
|
|
|
|
This new functions cleans up the common backend state. While this
currently only emits the destroy signal, this will also clean up
the renderer and allocator in upcoming patches.
|
|
|
|
If a mode is not provided, use the current mode intead.
Closes: https://github.com/swaywm/wlroots/issues/2904
|
|
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.
|
|
No need to take a generic wlr_output, we already know the output
comes from the DRM backend at that point.
|
|
This will allow a whole state to be applied at once, instead of
individually applying the buffer and the mode.
|
|
All of the information is in wlr_output_state.
|
|
This is now unused.
|
|
Replace it with drm_connector_state_mode, which computes the mode
from the wlr_output_state to be applied.
|
|
Replace it with drm_connector_state_active, which figures out
whether the connector is active depending on the wlr_output_state
to be applied.
|
|
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.
|
|
Populate the wlr_output_state when setting a mode. This will allow
drm_connector_set_mode to stop relying on ephemeral fields in
wlr_drm_crtc. Also drm_connector_set_mode will be able to apply
both a new buffer and a new mode atomically.
|
|
Instead of relying on wlr_output.pending to be empty when performing
backend-initiated CRTC commits, use a zero wlr_output_state.
|
|
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.

On multi-GPU setups, there is a primary DRM backend and secondary
DRM backends. wlr_backend_get_drm_fd will always return the parent
DRM FD even on secondary backends, so that users always use the
primary device for rendering.
However, for our internal rendering we want to use the secondary
device. Use allocator_autocreate_with_drm_fd to make sure the
allocator will create buffers on the secondary device.
We do something similar to ensure our internal rendering will
happen on the secondary device with renderer_autocreate_with_drm_fd.
Fixes: cc1b66364cc9 ("backend: use wlr_allocator_autocreate")
|
|
This function is only required because the DRM backend still needs
to perform multi-GPU magic under-the-hood. Remove the wlr_ prefix
to make it clear it's not a candidate for being made public.
|
|
Remove the assumption about EGL.

This reverts commit f9f90b417366581b58d806956c9b2099417ed4b3.
gbm_bo_get_modifier may return a modifier in these cases:
- The kernel doesn't support modifiers but Mesa does
- WLR_DRM_NO_MODIFIERS=1 is set
However, in both of these cases, the gbm_bo has been allocated
without modifiers.
There is already a check in drm_fb_create for modifiers:
wlr_drm_format_set_has will make sure buffers with an explicit
modifier will be rejected if the DRM backend doesn't support them.
So no need for an additional check in get_fb_for_bo.
Closes: https://github.com/swaywm/wlroots/issues/2896

On GPU unplug, disabling a CRTC can fail with EPERM.

|
Any use of the DRM FD after the remove event results in a "Permission
denied" error.
|

The previous code would always print "falling back to legacy method",
even if the format wasn't ARGB8888.
Drop get_fb_for_bo_legacy, since the code can just be inlined without
hurting readability.
Ideally we should only fallback to drmModeAddFB if the error code
indicates the BE failure, but the original PR [1] doesn't say what
error code is returned by the kernel.

We shouldn't strip a modifiers from buffers, because the will make
the kernel re-interpret the data as LINEAR on most drivers,
resulting in an incorrect output on screen.
|
|
|
|
|
|
PRIME support for buffer sharing has become mandatory since the renderer
rewrite. Make sure we check for the appropriate capabilities in backend,
allocator and renderer.
See also #2819.
|
|
We now do the test in drm_connector_test, called from
drm_connector_commit.
|
|
This allows callers to use wlr_output_test to figure out whether a
buffer can be scanned out prior to committing the output.
|
|
Let's not clutter the logs with error messages when a test-only
atomic commit fails.
|
|
The kernel ignores NONBLOCK when TEST_ONLY is set. Let's just not
set it, to make it clear it's unused.
|
|
We cannot scan-out DMA-BUFs with any flag right now.
|
|
Downgrade errors to DEBUG level, because drm_fb_create is used in
test_buffer, so errors aren't always fatal. Add ERROR logs at call
sites where a failure is fatal, to make it clear something wrong
happened.
