Well, I found this list of DRM drivers which includes "drm-rp1-dsi". I assume this is what you meant by the "separate DMR driver". drmOpen("drm-rp1-dsi") does run but nothing appears on the composite output.
It shouldn't matter that I'm running rpicam through an SSH session or a container, right? As long as it has access to /dev/dri/card0 it should appear on the composite out, overwriting the login prompt.
When trying `drmfd_ = open("/dev/dri/card0", O_RDWR | O_CLOEXEC);`, the segfault occurs because there is no null check on drmModeObjectGetProperties within drm_set_property. I am still investigating but it looks like the plane_id in the request is nonexistent.
