i mentioned that the pool library can act as a big
kernel lock a few weeks ago. i don't know if anyone
has thoughts on how to deal with this.
it isn't really a `big kernel lock' in the linux sense.
the big kernel lock was the device by which operating systems
written with only a uniprocessor
it isn't really a `big kernel lock' in the linux sense.
you're right, technically it is a very different problem.
the effects seem similar. the lock is just in the block allocator
rather than the syscall interface. if you're doing a lot of i/o
in a standard kernel, there's a lot of block
it's probablly worth mentioning that if you have nvram
in an emulator, your secstore password is available in the
clear to whomever can read your emulator's emulated disk.

As it appears, the (net)boot configuration, meaning the 'plan9.ini'
located in /cfg/pxe/, where '' is the netbooted
host ethernet address, was missing nvram parameters, preventing the cpu
kernel (9pccpu) to proceed with the boot sequence.
If this parameter (nvram or nvr)
I assume (perhaps incorrectly) that the netbooted host can not use a nvram
store located on kfs. Please share with the list if you are aware, or use
a different method to store your nvram data, either in virtualized
machines or physical hardware. Preferably without the use of disk/floppy

My latest motherboard even had one USB port inside the case

If its an emulated environment, just put it on an emulated disk.

I've made updates to gofs[1], documented in NOTES.
Goban[2] is a graphical interface to gofs, for playing
the game of Go with a partner, or just by oneself.
The original goban was written by Gorka, and I've
made quite a few changes to it, to be able to play
from gofs.
Usage:
Simply running
Quick update:
-r flag has been added to goban, to simply
watch ongoing games.
Further updates will probably go in a man
page that I haven't yet created.
Just so I don't spam 9fans.
Best,
ak
