2021-09-07backend/drm: rename enum wlr_drm_connector_state to statusSimon Ser
"state" is easily confused with wlr_output_state.
2021-09-03backend/drm: handle drm_surface_blit errorsSimon Ser
drm_surface_blit returns NULL on error. This can happen e.g. when the source buffer cannot be imported into EGL. Closes: https://github.com/swaywm/wlroots/issues/3154
2021-08-25backend/drm: introduce wlr_drm_bo_handle_tableSimon Ser
Using GBM to import DRM dumb buffers tends to not work well. By using GBM we're calling some driver-specific functions in Mesa. These functions check whether Mesa can work with the buffer. Sometimes Mesa has requirements which differ from DRM dumb buffers and the GBM import will fail (e.g. on amdgpu). Instead, drop GBM and use drmPrimeFDToHandle directly. But there's a twist: BO handles are not ref'counted by the kernel and need to be ref'counted in user-space [1]. libdrm usually performs this bookkeeping and is used under-the-hood by Mesa. We can't re-use libdrm for this task without using driver-specific APIs. So let's just re-implement the ref'counting logic in wlroots. The wlroots implementation is inspired from amdgpu's in libdrm [2]. Closes: https://github.com/swaywm/wlroots/issues/2916 [1]: https://gitlab.freedesktop.org/mesa/drm/-/merge_requests/110 [2]: https://gitlab.freedesktop.org/mesa/drm/-/blob/1a4c0ec9aea13211997f982715fe5ffcf19dd067/amdgpu/handle_table.c
2021-08-25backend/drm: generate CVT reduced modesSimon Ser
The Coordinated Video Timings (CVT) spec [1] defines two types of timings: the "CVT standard CRT" timings and the "CVT reduced blanking" timings (see section 3.6). The standard CRT timings include pauses in the video stream to allow CRT displays to reposition their electron beam at the end of each horizontal scan line [2]. While this was desirable a few decades ago, nowadays we can just generate a CVT reduced blanking timing by default. wlroots users can still set full custom DRM modes via wlr_drm_connector_add_mode.

2021-08-20backend/drm: try to allocate crtc for formatsRouven Czerwinski
To retrieve the formats, an allocated crtc is required. If there is no currently no crtc available, try to allocate it. This reproducable by having a disabled output and going through a suspend cycle with amdgpu. On start CRTCs look like this: 00:00:00.588 [DEBUG] [wlr] [backend/drm/drm.c:1099] Reallocating CRTCs 00:00:00.588 [DEBUG] [wlr] [backend/drm/drm.c:1110] State before reallocation: 00:00:00.588 [DEBUG] [wlr] [backend/drm/drm.c:1116] 'DP-1' crtc=0 state=1 desired_enabled=1 00:00:00.588 [DEBUG] [wlr] [backend/drm/drm.c:1116] 'DP-2' crtc=1 state=1 desired_enabled=1 00:00:00.588 [DEBUG] [wlr] [backend/drm/drm.c:1116] 'HDMI-A-1' crtc=-1 state=0 desired_enabled=0 00:00:00.588 [DEBUG] [wlr] [backend/drm/drm.c:1116] 'HDMI-A-2' crtc=-1 state=0 desired_enabled=0 00:00:00.588 [DEBUG] [wlr] [backend/drm/drm.c:1116] 'DVI-D-1' crtc=-1 state=0 desired_enabled=0 00:00:00.588 [DEBUG] [wlr] [backend/drm/drm.c:1167] State after reallocation: 00:00:00.588 [DEBUG] [wlr] [backend/drm/drm.c:1174] 'DP-1' crtc=0 state=1 desired_enabled=1 00:00:00.588 [DEBUG] [wlr] [backend/drm/drm.c:1174] 'DP-2' crtc=1 state=1 desired_enabled=1 00:00:00.588 [DEBUG] [wlr] [backend/drm/drm.c:1174] 'HDMI-A-1' crtc=-1 state=0 desired_enabled=0 00:00:00.588 [DEBUG] [wlr] [backend/drm/drm.c:1174] 'HDMI-A-2' crtc=-1 state=0 desired_enabled=0 00:00:00.588 [DEBUG] [wlr] [backend/drm/drm.c:1174] 'DVI-D-1' crtc=-1 state=0 desired_enabled=0 where DP-1 is than disabled.

[sway/config/output.c:435] Failed to commit output DP-1 where the primary format can't be queried since there is no crtc allocated for the connector. Allocating the connector inside drm_connector_get_primary_formats() fixes this issue. This is possible since the only user of get_primary_formats() is the swapchain allocation function, which is only called on output enable. Do the same thing for the cursor formats in case the user queries them before the output is enabled.
2021-08-17Revert "backend/drm: Check if output is enabled before sending frame event"Rouven Czerwinski
This reverts commit 85757665e6e1393773b36282aa244feb10b7a5fe. We now check if the output is enabled within wlr_output_send_frame, no need to handle this explicitly in the DRM backend. This also fixes a race which was introduced with this commit: if we schedule the flip, disable and commit the output before the flip happens, output.frame_pending will not be reset to false. We than always fail to enable the output subsequently: 00:07:13.276 [INFO] [sway/commands.c:257] Handling command 'output DP-2 enable' 00:07:13.276 [DEBUG] [sway/commands.c:428] Subcommand: enable 00:07:13.276 [DEBUG] [sway/config/output.c:204] Merging on top of existing output config 00:07:13.276 [DEBUG] [sway/config/output.c:227] Config stored for output DP-2 (enabled: 1) (-1x-1@-1.000000Hz position 0,0 scale -1.000000 subpixel unknown transform -1) (bg /home/phoenix/Pictures/Wallpapers/mine/oper.jpg fill) (dpms 1) (max render time: -1) 00:07:13.276 [DEBUG] [sway/config/output.c:351] Turning on output DP-2 00:07:13.276 [DEBUG] [sway/config/output.c:360] Set preferred mode 00:07:13.276 [DEBUG] [wlr] [backend/drm/drm.c:465] connector DP-2: Can't enable an output without a buffer 00:07:13.276 [DEBUG] [wlr] [types/wlr_output.c:689] Attaching empty buffer to output for modeset 00:07:13.277 [DEBUG] [sway/config/output.c:329] Output DPI: 162.560000x161.364706 00:07:13.277 [DEBUG] [sway/config/output.c:400] Auto-detected output scale: 1.000000 00:07:13.277 [DEBUG] [sway/config/output.c:430] Committing output DP-2 00:07:13.277 [DEBUG] [wlr] [types/wlr_output.c:729] Tried to commit a buffer while a frame is pending since the basic_output_test will always fail.

2021-08-10backend/drm: always perform a test commit in drm_connector_testSimon Ser
This allows callers to use wlr_output_test to check whether a mode can be enabled, for instance. Closes: https://github.com/swaywm/wlroots/issues/2250
2021-08-04backend/drm: require buffer on modeset in drm_connector_testSimon Ser
When testing a modeset, make sure the caller has also provided a buffer. This allows df0e75ba05e2 ("output: try skipping buffer allocation if the backend allows it") to work as expected with the DRM backend. Closes: https://github.com/swaywm/wlroots/issues/3086
2021-08-02backend/drm: preserve mode order from kernelSimon Ser
The kernel orders the mode list from highest to lowest. Preserve this ordering in the wlr_output.modes list.
2021-07-29output: drop wlr_output_state.buffer_typeSimon Ser
This is now unconditionally set to WLR_OUTPUT_STATE_BUFFER_SCANOUT.
2021-07-28backend/drm: fix wrong type for get_cursor_format return valuesSimon Ser
These are bools but should be pointers.
2021-07-28backend/drm: stop initializing renderer for parent backendSimon Ser
Unless we're dealing with a multi-GPU setup and the backend being initialized is secondary, we don't need a renderer nor an allocator. Stop initializing these.
2021-07-28backend/drm: remove SCANOUT check in drm_connector_testSimon Ser
We only accept SCANOUT, the buffer type should never be set to RENDER.
2021-07-28backend/drm: remove primary swapchainSimon Ser
We can't nuke it completely, we still need it for multi-GPU.
2021-07-28backend/drm: implement get_primary_formatsSimon Ser
2021-07-20backend/drm: stop restoring CRTCs on exitSimon Ser
This is the cause of the spurious "drmHandleEvent failed" messages at exit. restore_drm_outputs calls handle_drm_event in a loop without checking whether the FD is readable, so drmHandleEvent ends up with a short read (0 bytes) and returns an error. The loop's goal is to wait for all queued page-flip events to complete, to allow drmModeSetCrtc calls to succeed without EBUSY. The drmModeSetCrtc calls are supposed to restore whatever KMS state we were started with. But it's not clear from my PoV that restoring the KMS state on exit is desirable. KMS clients are supposed to save and restore the (full) KMS state on VT switch, but not on exit. Leaving our KMS state on exit avoids unnecessary modesets and allows flicker-free transitions between clients. See [1] for more details, and note that with Pekka we've concluded that a new flag to reset some KMS props to their default value on compositor start-up is the best way forward. As a side note, Weston doesn't restore the CRTC by does disable the cursor plane on exit (see drm_output_deinit_planes, I still think disabling the cursor plane shouldn't be necessary on exit). Additionally, restore_drm_outputs only a subset of the KMS state. Gamma and other atomic properties aren't accounted for. If the previous KMS client had some outputs disabled, restore_drm_outputs would restore a garbage mode. [1]: https://blog.ffwll.ch/2016/01/vt-switching-with-atomic-modeset.html
2021-07-12backend/drm: remove wlr_output_impl.export_dmabufSimon Ser
This is now provided by the generic wlr_output implementation.
2021-07-09backend/drm: remove backend arg from wlr_drm_interface.crtc_commitSimon Ser
The callee can just get it from the wlr_drm_connector.
2021-07-09backend/drm: move legacy-specific checks to legacy.cSimon Ser
Now that we have a test_only arg in crtc_commit, we can move the legacy checks to legacy.c.
2021-07-09backend/drm: add test_only arg to wlr_drm_interface.crtc_commitSimon Ser
Right now callers of drm_crtc_commit need to check whether the interface is legacy or atomic before passing the TEST_ONLY flag. Additionally, the fallbacks for legacy are in-place in the common code. Add a test_only arg to the crtc_commit hook. This way, there's no risk to pass atomic-only flags to the legacy function (add an assert to ensure this) and all of the legacy-specific logic can be put back into legacy.c (done in next commit).

2021-07-05backend/drm: don't clear pending cursor FB on failed commitSimon Ser
The previous fix tried to side-step cursor->pending_fb completely. However that messes up our buffer locking mechanism. Instead, stop clearing the pending cursor FB on a failed commit. The pending cursor FB will remain for the next commit. Fixes: 6c3d080e25e5 ("backend/drm: populate cursor plane's current_fb")
2021-07-05Revert "backend/drm: populate cursor plane's current_fb"Simon Ser
This reverts commit 6c3d080e25e56404228ad7704eed43e40fa0c623. Populating wlr_drm_plane.current_fb messes up the buffer's locking. The previous buffer is released while it's still being displayed on-screen.
2021-07-01buffer: make enum wlr_buffer_cap publicSimon Ser
Custom backends and renderers need to implement wlr_backend_impl.get_buffer_caps and wlr_renderer_impl.get_render_buffer_caps. They can't if enum wlr_buffer_cap isn't made public.
2021-06-24backend/drm: rename page_flip_handler to handle_page_flipSimon Ser
This is more consistent with the rest of the wlroots naming.
2021-06-20backend: add output state allow-listsSimon Ser
Right now, when a new output state field is added, all backends by default won't reject it. This means we need to add new checks to each and every backend when we introduce a new state field. Instead, introduce a bitmask of supported output state fields in each backend, and error out if the user has submitted an unknown field. Some fields don't need any backend involvment to work. These are listed in WLR_OUTPUT_STATE_BACKEND_OPTIONAL as a convenience.
2021-06-17backend/drm: populate cursor plane's current_fbSimon Ser
The set_cursor() hook is a little bit special: it's not really synchronized to commit() or test(). Once set_cursor() returns true, the new cursor is part of the current state. This fixes a state where wlr_drm_connector.cursor_enabled is true but there is no FB available. This is triggered by set_cursor() followed by a failed commit(), which resets pending_fb. We should definitely fix the output interface to make the cursor part of the pending state, but that's a more involved change.
2021-06-13backend/drm: remove test_bufferSimon Ser
Instead, call drm_connector_set_pending_fb.
2021-06-13backend/drm: move session check from test_buffer to drm_connector_testSimon Ser
The other caller (drm_connector_commit_state) already checks this.
2021-06-13backend/drm: move drm_connector_set_pending_fb upSimon Ser
This will be used in drm_connector_test shortly.
2021-06-13backend/drm: allocate a CRTC in drm_connector_testSimon Ser
We can't perform a test-only atomic commit if the connector is missing a CRTC.
2021-06-13backend/drm: allocate a CRTC in drm_connector_commit_stateSimon Ser
drm_connector_set_pending_fb needs a CRTC to import the buffer.
2021-06-13backend/drm: introduce drm_connector_alloc_crtcSimon Ser
This function allocates a CRTC for a connector if necessary.
2021-06-13backend/drm: allow committing a buffer and a mode togetherSimon Ser
Set the plane's pending FB before calling drm_connector_set_mode.
2021-06-13backend/drm: use atomic test-only commits for modifier fallbackSimon Ser
Instead of trying to perform a real modeset in init_renderer, perform an atomic test-only commit to find out whether disabling modifiers is necessary because of bandwidth limitations. This decouples init_renderer from the actual commit, making it possible to modeset an output with a user-supplied buffer instead of a black frame. We loose the ability to make sure the buffers coming from the swapchain will work fine when using the legacy interface. This can break i915 when atomic is disabled and modifiers enabled. But i915 always has atomic (so the user must explicitly disable it to run into potential bandwidth limitations) and is the only known problematic driver.
2021-06-02backend/drm: move cursor fields to wlr_drm_connectorSimon Ser
Doesn't make a lot of sense to split the cursor fields between wlr_drm_plane and wlr_drm_connector. Let's just move everything to wlr_drm_connector.
2021-06-02output: take a wlr_buffer in set_cursorSimon Ser
Instead of passing a wlr_texture to the backend, directly pass a wlr_buffer. Use get_cursor_size and get_cursor_formats to create a wlr_buffer that can be used as a cursor. We don't want to pass a wlr_texture because we want to remove as many rendering bits from the backend as possible.
2021-06-02backend/drm: remove format arg from drm_plane_init_surfaceSimon Ser
This was always set to ARGB8888.
2021-06-02backend/drm: implement get_cursor_formats and get_cursor_sizeSimon Ser
2021-04-30backend/drm: Do not require mode commit on enableKenny Levinsen
If a mode is not provided, use the current mode intead. Closes: https://github.com/swaywm/wlroots/issues/2904
2021-04-29backend/drm: introduce drm_connector_commit_stateSimon Ser
Backend-initiated mode changes can use this function instead of going through drm_connector_set_mode. drm_connector_set_mode becomes a mere drm_connector_commit_state helper.
2021-04-29backend/drm: take a wlr_drm_connector instead of a wlr_outputSimon Ser
No need to take a generic wlr_output, we already know the output comes from the DRM backend at that point.
2021-04-29backend/drm: take output state arg in drm_connector_commit_bufferSimon Ser
This will allow a whole state to be applied at once, instead of individually applying the buffer and the mode.
2021-04-29backend/drm: remove mode arg from drm_connector_set_modeSimon Ser
All of the information is in wlr_output_state.
2021-04-29backend/drm: remove mode arg from drm_connector_init_rendererSimon Ser
This is now unused.
2021-04-29backend/drm: remove wlr_drm_crtc_state.modeSimon Ser
Replace it with drm_connector_state_mode, which computes the mode from the wlr_output_state to be applied.
2021-04-29backend/drm: remove wlr_drm_crtc_state.activeSimon Ser
Replace it with drm_connector_state_active, which figures out whether the connector is active depending on the wlr_output_state to be applied.
2021-04-29backend/drm: remove wlr_drm_crtc.pending_modesetSimon Ser
Replace it with a new drm_connector_state_is_modeset function that decides whether a modeset is necessary directly from the wlr_output_state which is going to be applied.
2021-04-29backend/drm: fill scratch wlr_output_state for set_modeSimon Ser
Populate the wlr_output_state when setting a mode. This will allow drm_connector_set_mode to stop relying on ephemeral fields in wlr_drm_crtc. Also drm_connector_set_mode will be able to apply both a new buffer and a new mode atomically.
