Hi
Can I write a user space program or a kernel module to measure the
context switch latency? I dont think this is possible from user space,
was just curious whether there is any simple way of measuring this
latency.
Google a program called Hourglass, it might give you ideas.... or
lmbench.
lmbench is a set of tools that comes with the tool lat_ctx. if you want
to measure context switch latency you should use lat_ctx
