Hi all,
Can anyone help shed some light in my search for a low power minimal plan
9 hardware setup to start experimenting with. Has anyone had success running
plan 9 on a Fit PC (the only atom box we have access to)?
Gumstix would be ideal, but their plan 9 support is a bit half baked right
now.
I suppose the use of counting semaphores in sleep/wakeup could
help in cases like this (but I'm sure there are still plenty of
other scenarios where they might not help). The value of the
semaphore would represent something like number of things to
do, so acquire(sema) would (atomically) wait

Agreed, but is there a FORTRAN compiler/cross-compiler for Plan 9?
f2c (from netlib) is trivial to get running. This gives you Fortran 77. It
has been sufficient for my needs (spice, zork, some grib stuff).

this means that any dynamic allocation
of structures containing rendezvous is not possible because
structure can be free'd before the rendezvous lock is
dropped by the waking process.
Déjà vu all over again ...
This and other subtleties of sleep/wakeup were extensively explored
in 9fans back

Does inferno have support for (a) webcam(s)? Or are you using linux for
capturing things from the webcam?

the bug is calling wakeup(r) on deallocated r.
sleep and wakeup communicate about the event represented by r,
not the structure containing r.
in the case of this particular bug, i have at least 40µs
grace and the change has held up for 12 hrs, where i
could crash the machine in 5s before.
i don't know about you but if i were shipping code that
depended critically on not losing a race with a fast device,
it would keep me up at night.
wireless support: se lucho's note about his almost-done wifi driver.
That said, you might want wireless usb with the atheros chip (6000
series?) that does most of the wireless stack. Charles knows more.
webcam: is this a usb webcam? USB support is getting better.

How about reading /proc/$pid/environ (where $pid is the shell spawned for
command execution) before the $pid exits and transfering all the environment
variables back to the Acme's own environment?
plan9port runs in more places than linux.

it doesn't. the scenario in my first email has exactly one

Do you have spice mkfiles available somewhere?
Spice died when my previous venti server blew up. Re-doing
the port is on my todo list, but not very high at the moment.
