Improve AIX Support #1651

Closed Dylan-M closed 1 month ago

Dylan-M commented 1 month ago

Implement additional AIX support

I have very little Golang experience. So... please point out anything I'm doing wrong from Golang perspective Also anything I can do to improve efficiency of some of the things I had to do as loops to pick something out of several lines. Or really, anything else. I don't take offense, unless you're rude about it. Constructive criticism is always welcome.

This should now support all packages except process, which I don't have the time to develop (process is very in-depth)

Added:

Partially addresses #1490

@shirou If you're at all concerned about AIX support, I'm willing to be a code owner for the AIX portions only to help alleviate that. Alternatively, I can help you get set up with an emulated AIX system to work from.

Unrelated to this PR, but for my future reference, could you let me know the best way to set up an AIX emulation environment? Would QEMU be a good option?

Yes, but not using libvirt (virsh or the gui virt-manager). I scoured the internet, and played around a lot, to get this to work. It is a combination of other peoples' work, and my own knowledge. I only have it working for AIX 7.2 at this time, still working on 7.3.

# AIX 7.2 PowerPC "POWER9"
sudo qemu-system-ppc64 -M pseries,ic-mode=xics -cpu POWER9 \
  -smp 4,sockets=4,cores=2,threads=2,maxcpus=16 \
  -m 4096 \
  -name aix_7200-04-02-2027 \
  -netdev bridge,id=net0,br=virbr0 \
  -device spapr-vlan,netdev=net0,mac=52:54:00:49:53:14 \
  -device virtio-scsi,id=scsi0 \
  -drive file=/var/lib/libvirt/images/aix7.2-ppc64.qcow2,if=none,id=drive-scsi0-0-0-0,format=qcow2,cache=none \
  -device scsi-hd,bus=scsi0.0,channel=0,scsi-id=0,lun=0,drive=drive-scsi0-0-0-0,id=scsi0-0-0-0,bootindex=1 \
  -drive file=/path/to/iso/aix/7.2/aix_7200-04-02-2027_1of2_072020.iso,format=raw,media=cdrom,cache=unsafe

You can edit the cpu line, I've had it working with just smp 1 and memory of -m 2048.

EDIT: This was the command I used to create my disk image: sudo qemu-img create -f qcow2 /var/lib/libvirt/images/aix7.2-ppc64.qcow2 50G

Would you also be interested in my little test/sample program that I used to actually test this manually? I can dump it into a gist.

Here is the test program gist
