On i386 systems with MONITOR/MWAIT, you could use them; simpler than
adding support for IPIs, I imagine.

this got lost in a large patch that didn't get accepted, and i just turned it
up. i'd hate for
anyone else to trip over the same troubles. this fixes
- sneaky UTFmax dependencies
- a bug if %r is given with no matching format for rune r, where r>127.
- %, interacting badly with 0 padding.
- bad
there's a fix to a long-standing (but silly) bug in the 9atom's
screen.c that gives 10x the video performance. if you're using
a terminal with 9atom you may be interested in upgrading to
a new kernel.
enjoy.

i almost mentioned this, and it's on my list. i just haven't
had the time. it turns out that a naive implementation of
ipi'ing 1 proc per wakeup will have to watch out for the

The hlt instruction on x86 leaves the halt state after an external
interrupt is fired. I'm not sure why you think it doesn't work? If you
need to wake up other cores then you may need IPIs is that what you
mean?

Hi,
in pc/main.c idlehands() the kernel decides to release the CPU only
when you are not running a multicore kernel. As a result there is only
busy waiting. Unfortunately there is no hint telling why we do not let
the CPU rest a little.

i couldn't work out which hardware, usable by Asterix, could be
driven by another system instead.

Hi,
I'm currently looking for jobs in french research centers as a research engineer. I found
an open position in LIP (Lab of parallel programing, CNRS, Lyon, France) that is part of a
joint research unit with the Bell Labs, but I can't find any reference to Plan 9 in their
work.
Do you, Pl
