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

2022-07-11backend/wayland: handle high-res scroll eventsJosé Expósito
Receive high-resolution scroll events from the parent compositor using a Wayland listiner and emit the appropiate wlr_pointer signal.
2022-07-11backend/libinput: code style consistencyJosé Expósito
Reduce a level of identation in "handle_pointer_axis" to keep the consistency with "handle_pointer_axis_value120".
2022-07-11backend/libinput: handle high-res scroll eventsJosé Expósito
On newer versions of libinput, the event LIBINPUT_EVENT_POINTER_AXIS has been deprecated in favour of LIBINPUT_EVENT_POINTER_SCROLL_WHEEL, LIBINPUT_EVENT_POINTER_SCROLL_FINGER and LIBINPUT_EVENT_POINTER_SCROLL_CONTINUOUS. Where new events are provided by the backend, ignore LIBINPUT_EVENT_POINTER_AXIS, receive high-resolution scroll events from libinput and emit the appropiate wlr_pointer signal.
2022-07-11pointer: transform low-res to high-res axis eventsJosé Expósito
Currently, the "wlr_event_pointer_axis" event stores low-resolution values in its "delta_discrete" field. Low-resolution values are always multiples of one, i.e., 1 for one wheel detent, 2 for two wheel detents, etc. In order to simplify internal handling of events, always transform in the backend from the low-resolution value into the high-resolution value. The transformation is performed by multiplying by 120. The 120 magic number is used by the kernel and it is exposed to clients in the "WLR_POINTER_AXIS_DISCRETE_STEP" constant.
2022-07-11build: check if libinput supports high-res scrollJosé Expósito
Starting with Linux Kernel v5.0 two new axes are available for mice that support high-resolution wheel scrolling: REL_WHEEL_HI_RES and REL_HWHEEL_HI_RES. Both axes send data in fractions of 120 where each multiple of 120 amounts to one logical scroll event. Fractions of 120 indicate a wheel movement less than one detent. Three new events are now available on libinput: LIBINPUT_EVENT_POINTER_SCROLL_WHEEL, LIBINPUT_EVENT_POINTER_SCROLL_FINGER, and LIBINPUT_EVENT_POINTER_SCROLL_CONTINUOUS. These events replace the LIBINPUT_EVENT_POINTER_AXIS event, so new clients should simply ignore that event. Also, two new APIs are available to access the high-resolution data: libinput_event_pointer_get_scroll_value() and libinput_event_pointer_get_scroll_value_v120(). Add a project argument (LIBINPUT_HAS_SCROLL_VALUE120) to allow building against old versions of libinput or, where high-resolution scroll is available, support it.
2022-06-21wlr_input_device: remove anon union fieldIsaac Freund
This union is unnecessary since the recent input device refactor and can now be replaced by wlr_*_from_input_device() functions.
2022-06-19backend/drm: set "max bpc" to the maxSimon Ser
"max bpc" is a maximum value, the driver is free to choose a smaller value depending on the bandwidth available. Some faulty monitors misbehave with higher bpc values. We'll add a workaround if users get hit by these in practice. References: https://gitlab.freedesktop.org/wayland/weston/-/issues/612
2022-06-19backend/drm: remove unused CRTC count checkSimon Ser
drmIsKMS already checks for this.
2022-06-07backend/drm: fix NULL pointer deference due to typoIsaac Freund
2022-06-07backend/drm: make serial optionalSimon Ser
The EDID 1.4 spec says that the serial number is optional: > If this field is not used, then enter “00h, 00h, 00h, 00h”. Leave the wlr_output.serial field NULL in that case, and hide it from the output description.
2022-06-07backend/drm: unconditionally set "content type" to graphicsSimon Ser
CTA-861-G says that "graphics" is used to indicate non-analog (ie, digital) content. With that bit set, the sink should turn off analog reconstruction and other related filtering.
2022-06-02backend/drm: fix check for no-op commitsIsaac Freund
Since 6936e163b, we short-circut no-op commits as an optimization. However, the logic in the check was slightly off.
2022-06-02backend/drm: short-circuit no-op commitsSimon Ser
Some output commits (changing e.g. the output scale or transform) don't require any change in the KMS state. Instead of going through a KMS commit, return early. Blocking KMS commits can be expensive.
2022-06-01backend/drm: make commits without a buffer blockingSimon Ser
The wlr_output API requires compositors to wait for wlr_output.frame before submitting a new buffer. However, compositors can perform a commit which doesn't involve a buffer anytime. If the commit is a modeset, we set DRM_MODE_ATOMIC_ALLOW_MODESET and block until the commit is done. If it isn't, we currently always perform a non-blocking commit. This is an issue because a previous page-flip might still be in flight kernel-side, returning EBUSY. Fix this by using blocking commits when a buffer isn't submitted by the compositor.
