SDI is supposed to be a cross-platform spec, so mandating sysfs would

by Fibre channel), so you could hide OS implementation details. I am in

that library solutions tend to not work, because the library version is
never in synch with the standard/LLDD's. Given Linux vendor lead-times,
he does have a valid point.
Any kernel interface lib should be like libc or libalsa: it hides the
kernel details, however nasty they may be, shielding userspace and apps
from various changes over time.
