2022-04-28Zero-initialize structs in init functionsSimon Ser
Ensures there is no field left to its previous undefined value after calling an init function.
2022-03-13Pass O_CLOEXEC to drmModeCreateLease callsSamuel Čavoj
The lease_fd is currently being leaked to child processes Link: https://github.com/swaywm/sway/issues/4286#issuecomment-1065987957
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
2021-12-14backend/drm: use drmModeFormatModifierBlobIterNextSimon Ser
This avoids open-coding our own logic. The resulting code is more readable. References: https://gitlab.freedesktop.org/mesa/drm/-/merge_requests/146
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.
2021-12-09output: introduce wlr_output_set_nameSimon Ser
wlroots picks names for all outputs, but it might be desirable for compositor to override it. For instance, Sway will use a headless output as a fallback in case no outputs are connected. Sway wants to clearly label the fallback output as such and label "real" headless outputs starting from HEADLESS-1.
2021-11-29backend/drm: poison buffers which cannot be scanned outSimon Ser
Rather than repeatedly trying to import DMA-BUFs which cannot be scanned out, mark the failed ones with a special "poison" marker. Inspired from [1]. [1]: https://gitlab.freedesktop.org/wayland/weston/-/merge_requests/731
2021-11-26backend/drm: always add LINEAR to supported modifiersSimon Ser
2021-11-26backend/drm: fail on explicit modifier in drmModeAddFB2Simon Ser
drmModeAddFB2 doesn't support explicit modifiers. Only accept INVALID which indicates an implicit modifier and LINEAR which may indicate that GBM_BO_USE_LINEAR has been used.
2021-11-26Require INVALID for implicit format modifiersSimon Ser
See [1] for the motivation. [1]: https://gitlab.freedesktop.org/wayland/wayland-protocols/-/merge_requests/75

2021-11-18backend/drm: stop initializing backend rendererSimon Zeni
2021-11-17Remove support for DMA-BUF flagsSimon Ser
They are never used in practice, which makes all of our flag handling effectively dead code. Also, APIs such as KMS don't provide a good way to deal with the flags. Let's just fail the DMA-BUF import when clients provide flags.
2021-11-02backend/drm: handle per-connector hotplug eventsSimon Ser
When a connector ID is specified in a hotplug event, don't scan all connectors. Only scan the connector that has changed.
2021-10-29backend/drm: avoid creating empty FB_DAMAGE_CLIPS propSimon Ser
drmModeCreatePropertyBlob cannot create zero-sized blobs, that fails with EINVAL. Closes: https://github.com/swaywm/wlroots/issues/3297
2021-10-29backend/drm: get rid of BO handle tableSimon Ser
The BO handle table exists to avoid double-closing a BO handle, which aren't reference-counted by the kernel. But if we can guarantee that there is only ever a single ref for each BO handle, then we don't need the BO handle table anymore. This is possible if we create the handle right before the ADDFB2 IOCTL, and close the handle right after. The handles are very short-lived and we don't need to track their lifetime. Because of multi-planar FBs, we need to be a bit careful: some FB planes might share the same handle. But with a small check, it's easy to avoid double-closing the same handle (which wouldn't be a big deal anyways). There's one gotcha though: drmModeSetCursor2 takes a BO handle as input. Saving the handles until drmModeSetCursor2 time would require us to track BO handle lifetimes, so we wouldn't be able to get rid of the BO handle table. As a workaround, use drmModeGetFB to turn the FB ID back to a BO handle, call drmModeSetCursor2 and then immediately close the BO handle. The overhead should be minimal since these IOCTLs are pretty cheap. Closes: https://github.com/swaywm/wlroots/issues/3164

2021-09-30backend: create renderer and allocator in wlr_backend_autocreateSimon Ser
Instead of ensuring the renderer and allocator are initialized in each backend, do it in wlr_backend_autocreate. This allows compositors to create backends without any renderer/allocator if they side-step wlr_backend_autocreate. Since the wlr_backend_get_renderer and backend_get_allocator end up calling wlr_renderer_autocreate and wlr_allocator_autocreate, it sounds like a good idea to centralize all of the opimionated bits in one place.
2021-09-21backend/drm: add support for panel orientationSimon Ser
Expose the panel orientation with wlr_drm_connector_get_panel_orientation. Leave it to the compositor to consume this information and configure the output accordingly. Closes: https://github.com/swaywm/wlroots/issues/1581
2021-09-08backend/drm: introduce wlr_drm_backend_get_non_master_fdSimon Zeni
2021-09-08backend/drm: implement drm lease functionSimon Zeni
2021-09-07backend/drm: drop wlr_drm_connector.desired_modeSimon Ser
Previously used by attempt_enable_needs_modeset, but this has been dropped in the previous commit.
2021-09-07backend/drm: drop attempt_enable_needs_modesetSimon Ser
Modesets require a buffer. The DRM backend tried to auto-enable outputs when a CRTC becomes available in the past, but now that fails because no buffer is available. Instead of having this magic inside the DRM backend, a better approach is to do it in the compositor or in an optional helper.
2021-09-07backend/drm: drop drm_connector_init_rendererSimon Ser
drm_connector_set_pending_fb already takes care of this.
2021-09-07backend/drm: drop unused arg from get_possible_crtcsSimon Ser
Constify drmModeConnector while at it.
2021-09-07backend/drm: fix crash on VT switchSimon Ser
Don't set the MODE flag when disabling a CRTC. This fixes a NULL pointer dereference in drm_connector_state_init.
2021-09-07backend/drm: introduce wlr_drm_connector_stateSimon Ser
Previously, we were copying wlr_output_state on the stack and patching it up to be guaranteed to have a proper drmModeModeInfo stored in it (and not a custom mode). Also, we had a bunch of helpers deriving DRM-specific information from the generic wlr_output_state. Copying the wlr_output_state worked fine so far, but with output layers we'll be getting a wl_list in there. An empty wl_list stores two pointers to itself, copying it on the stack blindly results in infinite loops in wl_list_for_each. To fix this, rework our DRM backend to stop copying wlr_output_state, instead add a new struct wlr_drm_connector_state which holds both the wlr_output_state and additional DRM-specific information.
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
2021-08-25Move allocator stuff into new directorySimon Ser
Add render/allocator/ and include/render/allocator/ to hold everything allocator-related.
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.

[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.
2021-08-18backend/drm: add support for FB_DAMAGE_CLIPSSimon Ser
This allows the kernel to access our buffer damage. Some drivers can take advantage of this, e.g. for PSR2 panels (Panel Self Refresh) or for transfer over USB. Closes: https://github.com/swaywm/wlroots/issues/1267
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.

2021-08-17backend/drm: use addon for wlr_drm_fbSimon Ser
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
2021-08-10backend/drm: add proper error handling to wlr_drm_backend_createSimon Ser
Some listeners weren't removed and caused a use-after-free with e.g. vkms when used as a secondary GPU.
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.
