Hi,
Looks like sway and wlroots won't work with omaprdrm because of the following error:
backend/drm/drm.c:86: add_plane: Assertion !(type == DRM_PLANE_TYPE_PRIMARY && crtc->primary)
Looks like there should only be one primary plane per CRTC?
There's some discussion about that for a wlroots bug at:
https://github.com/swaywm/wlroots/issues/1943
And there's a link pointing to the kms docs:
https://01.org/linuxgraphics/gfx-docs/drm/gpu/drm-kms.html#plane-abstraction
Below is a quick hack fix I used to get sway started.
Not sure how the primary plane should be picked? I just used 0 as the primary plane to get things working :)
I can start xterm on sway, but so far no fonts only the borders.
Regards,
Tony
