I haven't seen that document, but if you say so. The TimeSys appnote
suggests using Linux userspace, but I can easily imagine cases where
porting the VxWorks "application" into the Linux kernel.

But do you really believe that supporting Linux-kernel-only deployments
in mainline would be something worth doing? Who aside from rcutorture
would really use such a thing?

Thanx, Paul
