I second this advice. It's pretty abnormal to need 100us resolution
in timing, especially in a "sloppy scheduling environment" like
that provided by the standard Linux kernels. Ask yourself whether
you really really need that, or if you don't have a design
masquerading as requirements. What does this timing requirement
stem from? Surely there is some reason for its existence. That
is probably a real requirement. See if you can accomplish the
same result without needing stringent timing.

I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
