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].)

2022-09-08backend/wayland: drop output_set_custom_mode()Simon Ser
It's an unnecessary wrapper.
2022-08-30backend/x11: report adaptive sync as enabledIsaac Freund
All we can do to influence adaptive sync on the X11 backend is set the _VARIABLE_REFRESH window property like mesa automatically does. We don't have any control beyond that, so we set the state to enabled on creating the output and never allow changing it (just like the Wayland backend).
2022-08-30backend/wayland: report adaptive sync as enabledIsaac Freund
Adaptive sync is effectively always enabled when using the Wayland backend. This is not something we have control over, so we set the state to enabled on creating the output and never allow changing it.
2022-08-30output: fail commits if adaptive sync cannot be enabledSimon Ser
Previously, adaptive sync was just a hint and wouldn't make any atomic commit fail if the backend didn't support it. The main reason is wlr_output_test wasn't supported at the time. Now that we have a way for compositors to test whether a change can work, let's remove the exception for adaptive sync and convert it to a regular output state field.

2022-08-11backend/wayland: fix touch device not added on startupSimon Ser
We were firing the new_input signal on backend initialization, before the compositor had the chance to add a listener for it. Mimick what's done for wl_keyboard: if the backend hasn't been started, delay wl_touch initialization. Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3473
2022-08-10backend/drm: drop enum wlr_drm_connector_statusSimon Ser
We can just use libdrm's drmModeConnection enum instead.
