2023-11-28backend/drm: use DRM_IOCTL_MODE_CLOSEFB instead of RMFBSimon Ser
RMFB implicitly performs a modeset to turn off any CRTC which is using the FB. This prevents seamless transitions between two DRM masters from working. Use the new CLOSEFB IOCTL which doesn't turn off anything and leave it up to the compositor to turn off outputs on shutdown if it wants to.
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.
2023-11-23backend/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.
2023-11-23util/transform: move over wl_output_transform helpersSimon Ser
These aren't really tied to wlr_output.
2023-11-19backend/drm: drop unnecessary flags in legacy interfaceSimon Ser
drm_crtc_commit() already ensures that atomic-only flags are disallowed.
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
2023-11-17backend/drm: free fb latersunzhguy
since 4932e0d347f("backend/drm: ensure plane surfaces are cleaned up on shutdown") at finish_drm_resources called drm_plane_finsh_surface has already free the fb Signed-off-by: zhoulei zhoulei@kylinos.cn Signed-off-by: sunzhguy <sunzhigang1@kylinos.cn>
2023-11-15backend/drm: leave CRTCs on when shutting downSimon Ser
This avoids a black screen during multiple seconds on shutdown. To fully allow for flicker-free transitions between DRM masters, we will also need [1]. [1]: https://gitlab.freedesktop.org/wlroots/wlroots/-/merge_requests/4394 Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3497
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.
2023-10-12Revert "backend/drm: Automatic non-blocking commits"Simon Ser
This reverts commit 45ba35719e874f7e8651e088c0582fe50301e731. Sadly, this causes regressions on amdgpu [1] and even with these fixed, there are fundamental issues with non-blocking modesets [2]. [1]: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3745 [2]: https://oftc.irclog.whitequark.org/dri-devel/2023-10-11#1697031838-1697036920;
2023-10-10backend/drm: Automatic non-blocking commitsKenny Levinsen
We currently only perform non-blocking commits for non-modeset commits with a buffer attached. Perform non-blocking commits whenever there is no pending pageflip event. If a non-blocking modeset commit fails, which can happen if the driver implicitly added more CRTCs to the commit that we did not know we had to wait for, retry with a blocking commit. References: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/2239
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
2023-10-03treewide: Migrate from sizeof(struct) to sizeof(*pointer) where practicalAlexander Orzechowski
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: Move output variable up in connect_drm_connectorAlexander Orzechowski
2023-08-16output: Add initialization state to wlr_output_initAlexander Orzechowski
2023-07-26backend/drm: restore custom modesSimon Ser
We were only restoring fixed modes here. The DRM backend no longer creates fixed modes when the compositor sets a custom mode, so we need to handle this situation when restoring. Closes: https://gitlab.freedesktop.org/wlroots/wlroots/-/issues/3698
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
2023-06-30backend/drm: handle output layer damageSimon Ser
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.

2023-06-19backend/drm: Use texture blend_mode for multigpu blitAlexander Orzechowski
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. Closes: https://github.com/swaywm/sway/issues/7632
2023-06-05add render timer APIRose Hudson
Based on five calls: wlr_render_timer_create - creates a timer which can be reused across frames on the same renderer wlr_renderer_begin_buffer_pass - now takes a timer so that backends can record when the rendering starts and finishes wlr_render_timer_get_time - should be called as late as possible so that queries can make their way back from the GPU wlr_render_timer_destroy - self-explanatory The timer is exposed as an opaque `struct wlr_render_timer` so that backends can store whatever they want in there.
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.
2023-05-30backend/drm: use new rendering APISimon Ser
2023-05-17drm_plane_pick_render_format: return false if no format could be foundAustin Shafer
Commit 90d08f8f1c40e2a302d62052435ff2abdb08a854 changed the way wlr_drm_format_intersect worked, including passing in a destination format list. This breaks scenarios where the intersection doesn't find any matching formats, since we still have a valid destination format set. This changes it to only return true if more than one matching format is present in the intersection list.
