64bit for 9front?

64bit for 9front?

[staalmannen]

Hi I just read about the rather interesting experimental "nix" 64-bit
plan9 kernel on 9fans.

https://bitbucket.org/npe/nix

My question is simply: would it be theoretically possible to set up
9front as 32/64 bit dual boot via a kernel choice (pcf vs nix) in the
plan9.ini?

How does plan9 64bit kernels work? Do they also support 32bit binaries
or would the 64bit directories first have to be populated?

You need a different 9load, pload(usually we use ppxeload). It's
included in the nix tree and will boot 32bit or 64bit kernels. Nix/9k
use /amd64/ binaries.

cd /sys/src; $objtype=amd64 mk installall

should work fine.

As to plan9.ini, you should just be able to set your bootfile to
/amd64/k8cpu. Here's one of mine:

bootfile=ether0!/amd64/9k8cpufs
