https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D278363 Bug ID: 278363 Summary: linsysfs: /sys/class/drm and /sys/dev/char/226:* contents don't match /dev/dri Product: Base System Version: Unspecified Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: iwtcex@gmail.com There are two significant issues here: 1. linsysfs creates entries for everything that has vgapci attached to it, regardless of whether the GPU has any associated /dev/dri/card* nodes =E2= =80=94 this might (and occasionally does) result in Mesa's libGL picking the wrong driv= er in multi-GPU configurations; 2. there are no entries for /dev/dri/renderD* nodes, which breaks Vulkan initialization, forcing Mesa to choose the software rendering fallback.
