https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D251844 --- Comment #2 from Conrad Meyer <cem@freebsd.org> --- DDC I2C support depends on GPU drivers providing an ioctl interface. The FreeBSD nvidia driver *does not* provide the ioctls, but the Linux nvidia driver does (support is present in the binary blob, but not exposed to userspace). I'm not sure if we have DDC/I2C ioctl support in either the In= tel or AMD GPU drivers. --=20 You are receiving this mail because: You are the assignee for the bug.=
