Product: Base System Version: Unspecified Hardware: amd64 OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: martin@kristensen.uk Created attachment 268374 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D268374&action= =3Dedit dmesg from the machine in question. On an EPYC 7003 series server with four identical Instinct MI50 GPUs, sysctl for hw.dri.0 and hw.dri.1 are created but hw.dri.2 and hw.dri.3 are not. Possibly causing the inability of the Vulkan loader to enumerate the device= s. /dev/dri/cardX and renderDX devices exist for all four cards, but vulkan is only able to load drivers for card0 and card1. dmesg shows two instances of "sysctl_add_oid: can't re-use a leaf (hw.dri.1.name). # pciconf -lv vgapci0@pci0:198:0:0: class=3D0x030000 rev=3D0x00 hdr=3D0x00 vendor=3D0x1= 002 device=3D0x66a0 subvendor=3D0x1002 subdevice=3D0x081e vendor =3D 'Advanced Micro Devices, Inc.
