2021-11-19output: use XRGB8888 format instead of ARGB8888Manuel Stoeckl
Most (and possibly all) compositors using wlroots only ever render fully opaque content. To provide better performance, this change switches the default format used by wlr_output buffers from ARGB8888 to the opaque XRGB8888. Compositors like mutter, kwin, and weston already default to XRGB8888, so this change is unlikely to expose any new bugs in underlying drivers and hardware. This does not affect the hardware cursor's buffer format, which is still ARGB8888 by default. As part of this change, the X11 backend (which does not support changing format at runtime) now picks a true color, 24 bit depth visual (i.e. XRGB8888) instead of a 32 bit depth (ARGB8888) one.

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.

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

2021-10-18Add error handling to backend creationAnthony Super
This commit adds two error-handling cases to the function attempt_dmr_backend. Specifically: - In the case where the number of found GPUs is zero, we now print a log message indicating this and return a NULL pointer - In the case where we could not successfully create a backend on any GPU, we now log a message indicating this and return a NULL pointer This allows us to provide more descriptive error messages, as well as avoid a SEGFAULT (the function `ensure_primary_backend_renderer_and_allocator` dereferences the pointer given, which could be NULL until this patch) when these cases arise.

2021-10-01backend/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.

2021-09-30backend: 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.

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.

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.

"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.
