cvs commit: src/sys/amd64/amd64 intr_machdep.c src/sys/i386/i386
Paolo Pisati
FreeBSD src repository
Modified files:
sys/amd64/amd64 intr_machdep.c
sys/i386/i386 intr_machdep.c
sys/kern kern_intr.c
sys/sys interrupt.h
Log:
Bring in the reminaing bits to make interrupt filtering work:
o push much of the i386 and amd64 MD interrupt handling code
(intr_machdep.c::intr_execute_handlers()) into MI code
(kern_intr.c::ithread_loop())
o move filter handling to kern_intr.c::intr_filter_loop()
o factor out the code necessary to mask and ack an interrupt event
(intr_machdep.c::intr_eoi_src() and intr_machdep.c::intr_disab_eoi_src()),
and make them part of 'struct intr_event', passing them as arguments to
kern_intr.c::intr_event_create().
o spawn a private ithread per handler (struct intr_handler::ih_thread)
with filter and ithread functions.
Approved by: re (implicit?)

[BAMF] A kmacy appears.
/wave wand
The kmacy is not amused. He drops a +1000-2 patch on your head. It hurts.
/summon phk
[BAMF] phk appears, wielding what appears to be a large axe.
phk smiles and drops a +4-8000 patch on you.
Your kernel is now empty. You are low on commit points. You are hungry.
/summon core
A voice comes from above, "You're on your own this time."
Connection timed out. Better luck next time!
