2022-12-07backend/drm: simplify dealloc_crtc() commitSimon Ser
No need to manually call drm_connector_state_init() here, we can just let drm_connector_commit_state() handle it.
2022-12-07backend/drm: fix VRR testSimon Ser
We were calling drm_connector_supports_vrr() before drm_connector_alloc_crtc(). Thus, when an output is currently off, the VRR test would always fail, because it checks that the vrr_enabled CRTC prop exists.
2022-12-06build: unify naming for HAVE_* definesSimon Ser
We sometimes used HAS_, sometimes polluted the LIBINPUT_ namespace, etc.
2022-12-06backend/libinput: use internal_configSimon Ser
Removes project arguments.
2022-12-06backend/x11: ensure buffers are released on shutdownSimon Ser
2022-12-06backend/wayland: ensure buffers are released on shutdownSimon Ser
destroy_wl_buffer() is called from backend_destroy(). We need to ensure the wlr_buffer is unlocked when we're waiting for a wl_buffer.release event from the parent compositor.
2022-11-25backend/session: make optionalSimon Ser
Some compositors are not interested in wlr_session, for instance nested compositors. Disabling wlr_session removes the udev dependency.
2022-11-25backend: use time helpers to implement timeoutsSimon Ser
Instead of hand-rolling get_current_time_msec(), let's just re-use the helper we already have in "util/time.h".
2022-11-25backend: error out when missing DRM and libinput in wlr_backend_autocreate()Simon Ser
Instead of returning an empty multi backend, fail with a clear error when both the DRM and libinput backends are disabled.
2022-11-25backend/session: disable libseat examples for subproject by defaultSimon Ser
We have no use for these.
2022-11-17backend/drm: don't damage output on CRTC changeSimon Ser
There's no reason why the output should be damaged here. The current buffer doesn't need to be re-painted.
2022-11-17output: call wlr_output_update_enabled() after commitSimon Ser
Backends no longer need to manually call wlr_output_update_enabled() in their commit hook: wlr_output will take care of that.
2022-11-15backend: rename backend to multi in wlr_backend_autocreate()Simon Ser
This function deals with multiple kinds of backends. Make it more obvious that this variable holds the multi backend which is returned to the user.
2022-11-15backend: drop wlr_backend_get_session()Simon Ser
This no longer has purpose.
2022-11-15backend: return wlr_session in wlr_backend_autocreate() callSimon Ser
Up until now, wlr_backend_autocreate() created the wlr_session and then stuffed it into struct wlr_multi_backend so that compositors can grab it later. This is an abuse of wlr_multi_backend and the wlr_backend API: wlr_backend_get_session() and wlr_multi_backend.session only exist to accomodate the needs of wlr_backend_autocreate(). What's more, the DRM and libinput backends don't implement wlr_backend_impl.get_session. Instead, return the struct wlr_session to the compositor in the wlr_backend_autocreate() call. wlr_backend_get_session() will be removed in the next commit.
2022-11-15backend/x11: use request_state when window is resizedSimon Ser
2022-11-15backend/wayland: use request_state when toplevel is resizedSimon Ser
2022-11-15backend/drm: only request page-flip if activeSimon Ser
It doesn't make sense to request a page-flip for a disabled output. Fixes: 84e727daae67 ("backend/drm: request page-flip event on modeset") Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3528
2022-11-15backend/drm: fix FPE when disabling outputSimon Ser
Fixes: 65836ce357e4 ("backend/drm: log modesetting commits") Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3534
2022-11-14backend/drm: log modesetting commitsSimon Ser
2022-11-14backend/drm: log refresh rate in HzSimon Ser
2022-11-11backend: remove const casts for pixman_region32_tSimon Ser
Pixman 0.42.0 has constified APIs for pixman_region32_t. We no longer need the casts.
2022-11-11build: move udev dep to backend/Simon Ser
The DRM, libinput and session use udev. They are all hosted under backend/.
2022-11-11backend/drm: ensure disconnected outputs are disabled after VT switchSimon Ser
The following situation can be dangerous: - Output DP-1 is plugged in, compositor enables it. - User VT switches away. - User unplugs DP-1. - User VT switches back. - scan_drm_connectors() figures out the output is now disconnected, uninitializes the struct wlr_output. - The loop restoring previous output state in handle_session_active() accesses the struct wlr_output to figure out what to restore. By chance, we zero out the struct wlr_output after uninitializing it, so enabled and current_mode will always be zero. But let's make sure we handle this case explicitly, to remind future readers that it exists and make the code less fragile.
2022-11-11backend/drm: request page-flip event on modesetSimon Ser
The old drm_connector_set_mode() function did that by calling drm_crtc_page_flip(). We lost this in the refactoring. Fixes: f216e979836a ("backend/drm: drop drm_connector_set_mode()")
2022-11-09backend/drm: use pnp.ids to fetch EDID datailliliti
2022-11-08Revert "backend/drm: fetch EDID manufacturer from udev_hwdb"Simon Ser
This reverts commit e646d882cf4949d290fff2ba3b7ae4c124f6f13d. This commit has added a dependency on udev_hwdb. This API isn't available on all platforms (e.g. FreeBSD), and further deepens our udev dependency. A better solution is being worked on in [1]. [1]: https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/3638
2022-11-02backend/drm: get possible CRTCs in create_drm_connector()Simon Ser
This stuff is immutable for a given connector.
2022-11-02backend/drm: extract create_drm_connector()Simon Ser
Move a bit more logic out of the big loop in scan_drm_connectors().
2022-10-19backend/drm: fetch current CRTC once on startupSimon Ser
Once we are DRM master, the CRTC cannot be changed behind our back except during a VT switch. After a VT switch, we try to restore whatever KMS state we had last programmed. Reloading the current CRTC from KMS breaks this and can result in a modeset without a FB. Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3432
2022-10-18backend/drm: log failures in drm_surface_blit()Simon Ser
Can make issues like [1] easier to debug. [1]: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3451
2022-10-17backend/drm: drop drm_crtc_page_flip()Simon Ser
Inline it in drm_connector_commit_state(). Brings us a step closer to unifying the test code-path and the commit code-path.
2022-10-17backend/drm: log when restoring mode after VT switch failsSimon Ser
Can make it easier to track down issues.
2022-10-17backend/drm: fix EINVAL atomic commits after VT switchSimon Ser
The drm_connector_commit_state() call in handle_session_active() was not resulting in any atomic commit, because it didn't match any of the if branches: active = true, no new buffer was committed, and adaptive sync/gamma LUT were unchanged. Thus the commit was a no-op. Later on, when the compositor performs regular page-flips, the kernel would return EINVAL indicating that a modeset was needed. Rework the logic to use a non-blocking page-flip commit if a buffer was committed, and use a blocking commit if the connector is on or is being disabled. The only case where we should skip the atomic commit is when disabling (active = false) an already-disabled connector (conn->crtc == NULL). Note, 6936e163b514 ("backend/drm: short-circuit no-op commits") has introduced early returns for other situations where we don't need to perform an atomic commit (e.g. updating scale or transform of an output). Fixes: f216e979836a ("backend/drm: drop drm_connector_set_mode()") Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3432
2022-10-17backend/drm: extract current mode logic into separate functionSimon Ser
Extract the logic to fetch the current mode to a separate function to make it more readable. Stop dying in an assert when get_drm_prop_blob() fails. Always make it so the drmModeModeInfo pointer is allocated so that we can free() it unconditionally.
2022-10-15backend/drm: extract connect_drm_connector() logicSimon Ser
We already have disconnect_drm_connector() to handle the CONNECTED → DISCONNECTED transition. Let's add connect_drm_connector() to handle DISCONNECTED → CONNECTED. This makes scan_drm_connectors() shorter and easier to follow. No functional change, literally just moving code around.
2022-10-14backend/drm: use atomic API to fetch current connector's CRTCSimon Ser
We were using the legacy API (with a detour through drmModeEncoder) to find out the current CRTC for a connector. Use the atomic API when available. Also extract the whole logic into a separate function for better readability, and better handle errors.
2022-10-13backend/drm: use wl_container_of() instead of casts for wlr_drm_modeSimon Ser
Instead of casting a wlr_output_mode to wlr_drm_mode, use wl_container_of() for slightly better type safety.
2022-10-13backend/drm/legacy: Fix whitespaceAlexander Orzechowski
This confused me while reading through.
2022-10-13backend: use global output name countersSimon Ser
The output names must be globally unique per the Wayland spec, even if the compositor creates multiple backends of the same kind.
2022-10-10backend/drm: drop drm_connector_set_mode()Simon Ser
Instead of special-casing modesets, we can just cut the wrapper and directly call drm_crtc_page_flip(). drm_connector_test() should already have the checks previously done in drm_connector_set_mode(), all we need to do is update enabled/mode after a successful atomic commit.
2022-10-07backend/drm: allocate connector CRTC on lease creationSimon Zeni
This was leading to crash in compositors if the wanted connector had no CRTC
2022-10-07backend/drm: nuke wlr_drm_connector.desired_enabledSimon Ser
This field becomes stale too easily: for instance, see 6adca4089cf4 ("backend/drm: don't unconditionally set desired_enabled"). Additionally, drm_connector_alloc_crtc() needs to do some weird dance, restoring its previous value. Instead, add a connector arg to realloc_crtcs() to indicate a new connector we want to enable.
2022-10-07backend/drm: drop unnecessary wlr_drm_connector.crtc checksSimon Ser
drm_connector_alloc_crtc() already checks this.
2022-10-04render: drop wlr_renderer_read_pixels() flagsSimon Ser
These are unused.
2022-10-03backend/drm: remove outdated TODOSimon Ser
This has been addressed in 8795dde94eeb ("Initialize connectors current mode to the mode used by KMS on startup.").
2022-10-03backend/drm: don't unconditionally set desired_enabledSimon Ser
We were unconditonally setting desired_enabled = true for all connected connectors. This makes realloc_crtcs() always keep a CRTC active for these, even if the user doesn't want to enable them.
2022-09-30backend/drm: fix missing wlr_output_state.allow_artifactsSimon Ser
Without allow_artifacts, applying the new state will fail because it requires ALLOW_MODESET. Fixes VT switch and disabling CRTCs.
2022-09-30output: add wlr_output_state.allow_artifactsSimon Ser
When starting up, the compositor might call wlr_output_set_mode() with a mode which is already the current one. wlroots will detect this and make the wlr_output_set_mode() call a no-op. During the next wlr_output_commit() call, wlroots will perform an atomic commit without the ALLOW_MODESET flag. This is an issue, because some drivers need ALLOW_MODESET even if the mode is the same. For instance, if the FB stride or modifier changed, some drivers require a modeset. Add a new flag "allow_artifacts" which is set when the compositor calls mode-setting functions. Use this flag to figure out whether we want to perform atomic commits with ALLOW_MODESET. (The name "allow_artifacts" is picked because ALLOW_MODESET is a misnomer, see [1].)
