This is a somewhat convoluted question, but here goes...
We are creating a system that has a "timeline" (e.g. tasks must
be completed in a given amount of time)
OK, so we have a processor (we'll stay generic at this point)
that will be running a linux based kernel, and we want to figure out how
much processor availability we have (e.g. clock tics in a given time).
We know that the kernel functions (including resource
allocation, interrupt hadling, and so on) take up some omount of CPU
horsepower (albeit small)
What is a good general rule of thumb for a barebones linux
system? I know this is gross estimation, but does the kernel use up 20%
of my CPU resources? 10%? Any ideas?
