2024-02-21backend/drm: don't destroy previous DRM master blobsSimon Ser
On startup, we fetch the previous MODE_ID blob ID so that compositors can keep using the previous mode if they want to. However, that blob doesn't belong to us, it belongs to the previous DRM master. As a result, we get an error when trying to destroy it. Fix this by tracking whether the blob belongs to us or not. Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3811
2024-02-21backend/drm: fix broken link to KMS property docsSimon Ser
The Linux graphics section of 01.org is no more. Link to more official docs instead.
2024-02-15backend/drm: move restore logic to drm.cSimon Ser
We'll need to use a bunch of internal functions from that file in the next commits.
2024-02-14backend/drm: atomically reset state after VT switchSimon Ser
Allows the KMS driver to parallelize the modesets, so should be faster than going through each CRTC one by one.
2024-02-14backend/drm: drop wlr_drm_backend arg from create_mode_blob()Simon Ser
No need for this, the backend can be grabbed from the connector.
2024-01-25backend/drm: drop wl_display argumentSimon Ser
We can grab the event loop from the wlr_session instead.
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: remove wlr_drm_renderer.backendSimon Ser
This is unused.
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
2023-11-23backend/session: take wl_event_loop instead of wl_displaySimon Ser
wl_display holds a lot more than wlr_session needs: wlr_session only needs to wait for a FD to become readable, but wl_display provides full access to the Wayland client and protocol objects. Switch to wl_event_loop to better reflect the above.
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.
2023-11-17backend/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
2023-10-30backend: 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.
2023-09-28backend/drm: Add async page flip support to legacyvaxerski
Atomic doesn't support such flags yet.
2023-06-30backend/drm: handle output layer damageSimon Ser
2023-06-12backend/drm: clip FB damageSimon Ser
The kernel complains when the damage exceeds the FB bounds: [73850.448326] i915 0000:00:02.0: [drm:drm_atomic_check_only] [PLANE:31:plane 1A] invalid damage clip 0 0 2147483647 2147483647 Make the DRM backend behave like the Wayland one and allow compositors to damage (0, 0, INT32_MAX, INT32_MAX) to repaint everything without needing to know the exact buffer size.

2023-05-11wlr_drm_format: Rework wlr_drm_format_intersectAlexander Orzechowski
Now it takes a reference to a destination format
2023-02-28backend/drm: use libdisplay-info for CVT mode generationSimon Ser
2023-02-28backend/drm: use libdisplay-info to parse EDIDSimon Ser
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 composition layerSimon Ser
This will be useful for implementing the output layers API.
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
2022-12-15backend/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.
2022-12-13backend/drm: rename wlr_drm_backend.outputs to connectorsSimon Ser
This list contains wlr_drm_connector entries, and there is no guarantee that the wlr_output fields are initialized.
2022-12-13backend/drm: add drm_connector_status_str()Simon Ser
Helper to stringify a connector status.
2022-12-07backend/drm: store pending FB in stateSimon Ser
Instead of having a pending_fb field on the struct wlr_drm_plane, move it to struct wlr_drm_connector_state. That way, there's no risk having a stale pending FB around: the state doesn't survive across tests and commits. The cursor is a special case because it's disconnected from the atomic state: the wlr_backend_impl.set_cursor hook sets the cursor for the next commit. Move the field to wlr_drm_connector.cursor_pending_fb.
2022-12-07backend/drm: use separate field to store pending cursor FBSimon Ser
We'll move the pending primary FB into the connector state in the next commit, dropping wlr_drm_plane.pending_fb in the process. Introduce a dedicated field for the cursor, which has to be managed in a special way due to our set_cursor API.
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
2022-10-07backend/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.
2022-09-22backend/drm: pass through mode picture aspect ratioSimon Ser
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
2022-08-10backend/drm: remove unused WLR_DRM_CONN_CLEANUPSimon Ser
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
2022-06-19backend/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
2022-06-07backend/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.
2022-05-25backend/drm: remove wlr_drm_surface.{width,height}Simon Ser
This information is stored in wlr_swapchain, no need to duplicate it.
2022-05-11backend/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
2021-12-14backend/drm: use drmCloseBufferHandleSimon Ser
This has been added in [1] and allows us to close buffer handles without manually calling drmIoctl. [1]: https://gitlab.freedesktop.org/mesa/drm/-/merge_requests/192
2021-12-13backend/drm: add wlr_drm_backend_monitorChris Chamberlain
This helper is responsible for listening for new DRM devices and create new child DRM backends as necessary.
2021-11-19backend/drm: scan leases on ueventSimon Ser
