current state:
shithub.us/rminnich/nix main branch
I made one change to nix/386/etherigbe.c, if CLS is 0 or 0xff, I just set
it to 64 and continue. Works fine.
I run NIX, and once the VM starts up:
bind -a '#l0' /net
bind -a '#I' /net
ipconfig
listen1 -tv1 tcp!*!23 /boot/rc -m /boot/rcmain -i
then on another terminal:
nc 127.0.0.1 2323
ps aux
Await 1 0:00 5:39 13K 20 rc
Wakeme 2 0:00 5:39 10K 53370 genrandom

Wakeme 17 0:00 5:32 13K 0 etherread6
Sleep 18 0:00 5:32 13K 0 ipconfig
Wakeme 20 0:00 5:25 13K 0 #I0tcpack
Await 38 0:00 0:08 13K 0 rc
Pread 40 0:00 0:00 13K 0 ps
so we can get in, next step is drawterm.
Then I can do the execac test.
I still get occasional panics on cclose, maybe the later commits resolve
this.
It's interesting looking around the 15y ago stuff.
/sys/src/nix/root/{suck,blow}.c are tests for the IBM blue gene torus.
You can really see the transition we were making from blue gene back to
amd64 for the NIX work. The blue gene kernel started with the original k8
work DOE sponsored starting in the 2005 timeframe. This is pretty clearly a
kernel caught mid change.
If you drawterm in, you're going to need to go with the old protocol on
17010, this code base is that old.
