Simon Ser a670ee7940 backend/x11: remove swapchain
Rely on wlr_output's generic swapchain handling.

We still need a renderer for cursor readback, sadly.

Simon Ser 44feb832f9 backend/headless: remove swapchain
Rely on wlr_output's generic swapchain support instead of creating our
own. The headless output now simply keeps a reference to the front buffer
and does nothing else.

Simon Ser b86a0c8d8f backend/drm: move cursor fields to wlr_drm_connector
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.

Simon Ser 2b0a1aeed5 output: take a wlr_buffer in set_cursor
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.

Simon Ser 01e0f51fad backend/drm: introduce drm_plane_pick_render_format
This is a new helper function to pick a render format suitable for

Simon Ser ce3e819b33 backend: stop using renderer to get the buffer type
When picking a format, the backend needs to know whether the
buffers allocated by the allocator will be DMA-BUFs or shared
memory. So far, the backend used the renderer's supported
buffer types to guess this information.

This is pretty fragile: renderers in general don't care about the
SHM cap (they only care about the DATA_PTR one). Additionally,
nothing stops a renderer from supporting both DMA-BUFs and shared
memory, but this would break the backend's guess.

Instead, use wlr_allocator.buffer_caps. This is more reliable since
the buffers created with the allocator are guaranteed to have these
caps.

Simon Ser c9c2d7539c backend/drm: fill scratch wlr_output_state for set_mode

wlr_drm_crtc. Also drm_connector_set_mode will be able to apply
both a new buffer and a new mode atomically.

Simon Ser e7f68ba081 backend/drm: fix allocator DRM FD on multi-GPU setups
On multi-GPU setups, there is a primary DRM backend and secondary
DRM backends. wlr_backend_get_drm_fd will always return the parent
DRM FD even on secondary backends, so that users always use the
primary device for rendering.

However, for our internal rendering we want to use the secondary
device. Use allocator_autocreate_with_drm_fd to make sure the
allocator will create buffers on the secondary device.

We do something similar to ensure our internal rendering will
happen on the secondary device with renderer_autocreate_with_drm_fd.

Simon Ser 0411dc0663 Revert "backend/drm: fail instead of stripping a modifier"
This reverts commit f9f90b4173.

gbm_bo_get_modifier may return a modifier in these cases:

- The kernel doesn't support modifiers but Mesa does
- WLR_DRM_NO_MODIFIERS=1 is set

However, in both of these cases, the gbm_bo has been allocated
without modifiers.

There is already a check in drm_fb_create for modifiers:
wlr_drm_format_set_has will make sure buffers with an explicit
modifier will be rejected if the DRM backend doesn't support them.
So no need for an additional check in get_fb_for_bo.

Simon Ser e804de923d backend/drm: clarify error message on drmModeAddFB fallback
The previous code would always print "falling back to legacy method",
even if the format wasn't ARGB8888.

Drop get_fb_for_bo_legacy, since the code can just be inlined without
hurting readability.

Ideally we should only fallback to drmModeAddFB if the error code
indicates the BE failure, but the original PR [1] doesn't say what
error code is returned by the kernel.

Simon Ser b89bcffea4 render/egl, backend/wayland: add workaround for split render/display setups
Split render/display setups have two separate devices: one display-only
with a primary node, and one render-only with a render node. However
in these cases the EGL implementation and the Wayland compositor will
advertise the display device instead of the render device [1]. The EGL
implementation will magically open the render device when the display
device is passed in.

So just pass the display device as if it were a render device. Maybe in
the future Mesa will advertise the render device instead and we'll be
able to remove this workaround.
