next in thread | raw e-mail | index | archive | help
I have some code (in stable) which is invoked from the idle
loop, see below. I was trying to port it to CURRENT, but
cannot find where the idle_loop (or idlethread ?) has gone.
Any pointers ? A grep for idlethread did not return
anything that i could parse.
Furthermore, what kind of locking should i use instead of
splimp() (the procedures called by ether_input() are a
stripped down, bounded-execution-time version of the
interrupt service routines for ethernet adapters).
thanks
luigi
