Re: RFC: mpsafe bridge and NIC drivers (vioif and wm)


I've prepared a trial patch of MPSAFE networking.

It enables the interrupt handler of if_wm to run without
KERNEL_LOCK; an interrupt context and a LWP context (e.g.,
wm_start) run in parallel safely.

You can try it by applying the patch to -current
and commenting in NET_MPSAFE in sys/net/if.h.

A complete patch of my work can be found at usual places:
