2023-12-30backend/drm: save current refresh rateSimon Ser
wlr_output.refresh is populated by core wlr_output, and thus will be zero for a custom mode with an unset refresh rate. Save the refresh rate from the drmModeModeInfo in wlr_drm_connector instead. Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3791
2023-11-30backend/drm: move drm_plane_finish_surface() to drm.cSimon Ser
This function touches queued_fb/current_fb, which the renderer has nothing to do with.
2023-11-30backend/drm: split wlr_drm_fb related functions into separate fileSimon Ser
2023-11-25Cleanup wlr_matrix.h includesSimon Ser
Many files used to require wlr_matrix but no longer do.
2023-11-23output: take wl_event_loop in wlr_output_init()Simon Ser
We don't need the whole wl_display here anymore. The wl_event_loop is enough.
2023-11-23util/transform: move over wl_output_transform helpersSimon Ser
These aren't really tied to wlr_output.
2023-11-19backend/drm: add wlr_drm_connector_state.nonblockSimon Ser
Instead of having this condition checked in multiple places, centralize it so that they don't go out-of-sync.
2023-11-19backend/drm: fix pending page-flip checkSimon Ser
This chunk of code was moved by mistake. Fixes: 3b53d1cbf199 ("backend/drm: introduce page-flip tracking struct")
2023-11-17backend/drm: Destroy page flips on backend destroyAlexander Orzechowski
When we destroy the backend, page flips will no longer be invoked meaning those won't clean up the page flips for us.
2023-11-17backend/drm: Track page flips in listAlexander Orzechowski
2023-11-17backend/drm: introduce page-flip tracking structSimon Ser
Introduce a per-page-flip tracking struct passed to the kernel when we request a page-flip event for an atomic commit. The kernel will pass us back this pointer when delivering the event. This eliminates any risk of mixing up events together. In particular, if two events are pending, or if the CRTC of a connector is swapped, we no longer blow up in the page-flip event handler. Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3753
2023-11-15backend/drm: ensure plane surfaces are cleaned up on shutdownSimon Ser
Right now this is done "by chance" because we disable all CRTCs on shutdown. However, we'll stop doing this. Plus, if disabling a CRTC fails, we don't cleanup properly.
2023-10-30backend: drop wlr_backend_get_presentation_clock()Simon Ser
We can just assume CLOCK_MONOTONIC everywhere. Simplifies the backend API, and fixes clock mismatches when multiple backends are used together with different clocks.
2023-10-09output: allow_artifacts -> allow_reconfigurationKenny Levinsen
The name "allow_artifacts" and associated description is very vague, and theoretically allow for tearing behavior. Clarify that we only intend to mean artifacts related to output configuration (e.g., modesets). References: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3740
2023-10-02backend/drm: restore pending page-flip check when tearingSimon Ser
DRM_MODE_PAGE_FLIP_ASYNC doesn't allow user-space to submit new buffers before waiting for the uevent: the kernel will return EBUSY in that case. Fixes: c2aa7fd965cb ("backend/drm: Add async page flip support to legacy")
2023-09-28backend/drm: Add async page flip support to legacyvaxerski
Atomic doesn't support such flags yet.
2023-09-07backend/drm: Compute custom mode correctlyAlexander Orzechowski
2023-08-25backend/drm: drop no-op shortcutSimon Ser
Since e5fc8cd4c734 ("output: trigger frame/present events on all commits on enabled output"), any commit on an enabled output is supposed to trigger frame/present events. The DRM backend was skipping the commit completely for no-op commits. Stop doing so. Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3719
2023-08-23output: trigger frame/present events on all commits on enabled outputSimon Ser
Up until now, frame/present events were only triggered when the user submitted a buffer. Change the wlr_output API so that these events are triggered when any commit is applied on an enabled output. Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3708
2023-08-23backend/drm: report !presented if session is inactiveRose Hudson
2023-08-23backend/drm: don't set frame_pending on modesetRose Hudson
https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3664#note_2020392 we're gonna have to trust Simon on this one 🤞
2023-08-16backend/drm: Use output state to set init modeAlexander Orzechowski
2023-08-16backend/drm: Move output variable up in connect_drm_connectorAlexander Orzechowski
2023-08-16output: Add initialization state to wlr_output_initAlexander Orzechowski
2023-07-14backend/drm: stop checking for wlr_client_bufferSimon Ser
wlr_client_buffer is a bad indicator for direct scan-out. Compositors might use the underlying wlr_buffer instead.
2023-07-11Use wl_container_of() instead of castsSimon Ser
This slightly improves type safety. The culprits were found with: git grep -E '\([a-z0-9_ ]+ \*\)\W?[a-z]'
2023-07-07Use struct initializers instead of memset()Simon Ser
This is a bit more type-safe.
2023-06-30backend/drm: use panel_orientation if it is setClayton Craft
This fixes an issue where the panel_orientation parameter was set but wlroots was ignoring it and returning OUTPUT_TRANSFORM_NORMAL. Fixes 2e12de96
2023-06-27output: Set output mode during main commitAlexander Orzechowski
Removes duplication across all the backends to finally apply the mode to the output.
2023-06-27backend/drm: Don't add pollute fixed modes list with custom modesAlexander Orzechowski
Nobody remembers why this is done and it isn't that great if people use a lot of custom modes.
2023-06-26backend/drm: remove duplicate needs_frame() in set_cursor()Simon Ser
wlr_output_update_needs_frame() is called unconditionally at the end of the function already.
2023-06-23output: add wlr_output_state_init()Simon Ser
This changes the semantics of wlr_output_state. Instead of having fields with uninitialized memory when missing from the committed bitflag, all fields are always initialized (and maybe NULL/empty), just like we do in wlr_surface_state. This reduces the chances of footguns when reading a field, and removes the need to check for the committed bitfield everywhere. A new wlr_output_state_init() function takes care of initializing the Pixman region.
2023-06-22backend/drm: fix libliftoff_plane double-freeSimon Ser
Destroying the liftoff_device invalidates all of the liftoff_planes. Destroy the liftoff_planes before the liftoff_device to fix this.
2023-06-21backend/drm: Fix typoAlexander Orzechowski
2023-05-31backend/drm: introduce wlr_drm_mode_get_info()Simon Ser
This allows compositors to get back the raw drmModeModeInfo and look at DRM-specific fields and flags.
2023-05-11wlr_drm_format: Rework wlr_drm_format_intersectAlexander Orzechowski
Now it takes a reference to a destination format
2023-05-11wlr_drm_format: Introduce drm_format_finishAlexander Orzechowski
2023-03-20backend/drm: log drm_connector_alloc_crtc() failuresSimon Ser
Helps figuring out why e.g. get_primary_formats fails.
2023-02-28backend/drm: use libdisplay-info for CVT mode generationSimon Ser
2023-02-21render/swapchain: make publicSimon Ser
We've had this struct for a while. It'd be useful for compositors if they want to manage the swap chains themselves instead of being forced to use wlr_output's. Some compositors might also want to use a swapchain without an output.
2023-02-21backend/drm: drop wlr_drm_layer.pending_{width,height}Simon Ser
No need to store this info in struct wlr_drm_layer. We can just extract the size when we need it.
2023-02-20backend/drm: send output layer feedback eventsSimon Ser
2023-02-20backend/drm: add support for output layersSimon Ser
2023-02-20backend/drm: add libliftoff interfaceSimon Ser
2023-02-20backend/drm: init wlr_drm_plane for all plane typesSimon Ser
2023-01-31backend/drm: set "max bpc" property based on pixel formatSimon Ser
Since 1d581656c756 ("backend/drm: set "max bpc" to the max") we set the "max bpc" property to the maximum value. The kernel driver is supposed to clamp this value depending on hardware capabilities. All kernel drivers lower the value depending on the GPU capabilities. However, none of the drivers lower the value depending on the DP-MST link capabilities. Thus, enabling a 4k@60Hz mode can fail on some DP-MST setups due to the "max bpc" property. Additionally, it's not a good idea to unconditionally set "max bpc" to the max. A high bpc consumes more lanes and more clock speed, which means higher power consumption and the busy lanes cannot be used for something else (e.g. other data transfers on a USB-C cable). For now, let's tie the "max bpc" to the pixel format of the buffer. Introduce a heuristic to make "high bit-depth buffer" a synonym of "I want the best quality". This is not perfect: a "max bpc" higher than 8 might be desirable for pixel formats with a color depth of 8 bits, for instance when the color management KMS properties are used. But we don't really support that yet, so let's leave this for later. Closes: https://github.com/swaywm/sway/issues/7367
2022-12-16backend/drm: check return value of get_drm_{connector,crtc}_props()Simon Ser
We already do it for get_drm_plane_props().
2022-12-15backend/drm: remove wlr_drm_crtc.legacy_crtcSimon Ser
We only need it for one thing: gamma size. Moreover, some bits in the drmModeCrtc will become out-of-date, for instance the current mode, so let's avoid caching the whole struct and only keep what we know won't change.
2022-12-15backend/drm: fetch fresh legacy CRTC in connector_get_current_mode()Simon Ser
connect_drm_connector() may be called long after create_drm_connector(). During that time the DRM mode might have changed. Avoid working with stale information.
2022-12-13backend/drm: drop unused arg in connector_get_current_mode()Simon Ser
