[cpia] profiling device drivers

[Jack Diederich]

hi all,

I did some searches on google, redhat & the LDP, but I couldn't
find any articles on how to profile/benchmark device drivers.
Does anyone know how this works?

The reason I ask is that I was playing around w/ yuvconvert to
streamline it a bit (it seemed like the kind of frequently called
math heavy routine that might benefit).  If my changes sped it
up at all, it isn't noticeable. I'd still like to know where
the driver spends most of its time.

thanks,
