https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D217886 --- Comment #3 from holindho@saunalahti.fi --- (In reply to Matthew Rezny from comment #2) Good to hear it's getting replaced. Tracing the code from gbm/EGL down to libdevq revealed plenty of duplicated fragile looking code that attempts to figure out the device / bus ids. The root cause of why I'm seeing the problem and many others are not seems = to be in the ACPI parser in the kernel. Apple's firmware is probably a little broken and hands out weird PCI bus entries which, for instance, Linux seems= to skip as invalid, but FreeBSD takes them in, creating an inconsistent PCI de= vice tree.=20 However, libdevq's parsing that the patch addresses still seems to me as br= oken as the first form does not appear valid at all on 11.0 systems (which just = fall back to the older parsing method). I can live with my local patch, though, until a better libdrm emerges. --=20 You are receiving this mail because: You are the assignee for the bug.=
