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. |
