2022-10-03backend/drm: remove outdated TODOSimon Ser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.
2022-08-10backend/drm: drop WLR_DRM_CONN_NEEDS_MODESETSimon Ser
- Add wlr_output.enabled checks to CONNECTED checks - Replace NEEDS_MODESET with CONNECTED

2022-07-25backend/drm: use drmModeGetConnectorTypeNameSimon Ser
No need to manually maintain this table now. The wlroots names and the libdrm (= kernel) names all match. References: https://gitlab.freedesktop.org/mesa/drm/-/commit/50f8d517733d24fce6693ffae552f9833e2e6aa9
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. Closes: https://github.com/swaywm/sway/issues/6962 References: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/2239
2022-05-31backend/drm: improve atomic commit flag loggingSimon Ser
We weren't logging all of the flags, which made debugging more difficult.
2022-05-30output: pass wlr_output_state to backendSimon Ser
Groundwork for the following commits. The goal is to allow users to specify their own wlr_output_state instead of wlr_output.pending.
2022-05-27backend/x11: fix output model strdup callSimon Ser
References: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3434#note_1401193 Fixes: be86145322e6 ("output: turn make/model/serial into char *")
2022-05-26backend/drm: fix crash with null serialvaxerski
backend/drm: use serial_str instead
2022-05-26output: turn make/model/serial into char *Simon Ser
This allows the make/model/serial to be NULL when unset, and allows them to be longer than the hardcoded array length. This is a breaking change: compositors need to handle the new NULL case, and we stop setting make/model to useless "headless" or "wayland" strings.
2022-05-26backend/drm: fix crash in init_drm_surfaceSimon Ser
Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3434
2022-05-25backend/drm: remove wlr_drm_surface.{width,height}Simon Ser
This information is stored in wlr_swapchain, no need to duplicate it.
2022-05-24backend/drm: allow non-linear modifiers for multi-GPUSimon Ser
Prior to [1], if an entry in a DRM format set was different than a single LINEAR modifier, implicit modifiers were always allowed. This has changed and now implicit modifiers are only allowed if INVALID is in the list of modifiers. So now we can safely enable explicit modifiers for cross-GPU imports, without risking receiving buffers with an implicit modifier. This should improve perf a bit on setups where two GPUs from the same vendor are used. This fixes the first bullet point from [2].

2022-05-11backend/drm: fetch EDID manufacturer from udev_hwdbSimon Ser
Maintaining our internal table up-to-date is tedious: one needs to manually go through the PnP ID registry [1] and check whether we're missing any entry. udev_hwdb already has an API to fetch a manufacturer name from its PnP ID. Use that instead. [1]: https://uefi.org/pnp_id_list
2022-05-10backend/headless: allow variable refresh rateSimon Ser
Instead of waking up each 16ms to emit a frame event, arm the timer when the output is committed. This allows the headless backend to idle when nothing changes on screen, and behaves similarly to the other backends.
