Rouven Czerwinski 9b7803a9b3 backend/drm: try to allocate crtc for formats ... 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.		3 years ago
