2024-02-15Define _POSIX_C_SOURCE globallySimon Ser
Stop trying to maintain a per-file _POSIX_C_SOURCE. Instead, require POSIX.1-2008 globally. A lot of core source files depend on that already. Some care must be taken on a few select files where we need a bit more than POSIX. Some files need XSI extensions (_XOPEN_SOURCE) and some files need BSD extensions (_DEFAULT_SOURCE). In both cases, these feature test macros imply _POSIX_C_SOURCE. Make sure to not define both these macros and _POSIX_C_SOURCE explicitly to avoid POSIX requirement conflicts (e.g. _POSIX_C_SOURCE says POSIX.1-2001 but _XOPEN_SOURCE says POSIX.1-2008). Additionally, there is one special case in render/vulkan/vulkan.c. That file needs major()/minor(), and these are system-specific. On FreeBSD, _POSIX_C_SOURCE hides system-specific symbols so we need to make sure it's not defined for this file. On Linux, we can explicitly include <sys/sysmacros.h> and ensure that apart from symbols defined there the file only uses POSIX toys.
2024-02-15backend/drm: skip reset after VT switch if possibleSimon Ser
If all connectors and planes already have the right CRTC set, or are disabled, we can skip the device-wide reset after a VT switch. I've contemplated using a more fine-grained logic to only reset the connectors, CRTCs and planes that need to be migrated. However, writing a correct algorithm for this would be quite involved, and it doesn't seem worth the trouble anyways. Closes: https://github.com/swaywm/sway/issues/7956
2024-02-15backend/drm: fix typo in restore_drm_device() commentSimon Ser
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: call get_drm_connector_props() when creating connectorSimon Ser
This function fetches property IDs. These don't change for the lifetime of the connector. Instead of refreshing the property IDs on hotplug (and leaving property IDs unset for disconnected connectors), only fetch the property IDs when we create the connector.
2024-02-14backend/drm: extract logic to build current connector stateSimon Ser
2024-02-14backend/drm: use early return in handle_session_active()Simon Ser
2024-02-14backend/drm: add destroy_blob()Simon Ser
Centralizes the logic to destroy a DRM blob: check whether it's zero, and print a nice error message.
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.
2024-02-14backend/drm: add drm_page_flip_create()Simon Ser
2024-02-14backend/drm: fix fb_damage_clips_arr memory leakSimon Ser
2024-02-12backend/drm: drop unnecessary _XOPEN_SOURCESimon Ser
We only need base POSIX here.
2024-02-02allocator: remove backend parameter in allocator_autocreate_with_drm_fdAustin Shafer
Since we only use the backend capabilities here we can simply pass them in directly. This allows other locations to create an allocator even if they don't have a backend. They can simply specify the caps they want instead.
2024-01-31backend/drm: use wlr_drm_backend.name for fd cloningKirill Primak
This also fixes a memleak.
2024-01-27backend/drm: add support for atomic tearing page-flipsSimon Ser
The kernel patches [1] have been merged. [1]: https://patchwork.freedesktop.org/series/120103/
2024-01-25backend/drm: drop wl_display argumentSimon Ser
We can grab the event loop from the wlr_session instead.
2024-01-25backend: stop calling wl_display_terminate()Simon Ser
Leave it up to the compositor to decide what to do when a backend becomes unavailable.
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
2023-12-12backend/drm: return secondary backend DRM FDSimon Ser
It can be useful for compositors to get the real DRM FD instead of the one from the parent compositor. For instance, some compositors might want to perform some DRM IOCTLs there to check the driver name, fetch some DRM resources, etc. This will also be a requirement for direct scanout on secondary GPUs.
2023-12-12backend/drm: add wlr_drm_backend_get_parent()Simon Ser
Allows compositors to figure out whether a DRM backend is secondary on a multi-GPU setup.
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
2023-11-28backend/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
