Running illumos aarch64 on Asahi Linux on M1/M2 
-----------------------------------------------


# git clone the 6.1.0 branch 

git clone --branch osport/qemu-6.1.0 https://github.com/n-hys/qemu/ 

# copy the patched files to the $SRC/ (where you cloned qemu)  

cp ebpf_rss.c         $SRC/qemu/ebpf/
cp fdmon-io_uring.c   $SRC/qemu/util/ 

cd qemu
./configure --target-list=aarch64-softmmu
make
sudo make install

# Make sure you have the following file 

cat /usr/local/etc/qemu/bridge.conf 
allow br0

# Then just use the ready made images + scripts 
# You can download the ready-made images from here 

https://astr0baby.online/Solaris/illumos-aarch64/ 
 - Download disk.img.xz and uncompress (unxz disk.img.xz) 
 - Download flash.bin 
 - Download intetboot.bin 
 - Download intetboot.out            
 - Download run.sh  

# Additional tools need to be pulled for the below bridging to work on the Asahi 

sudo pacman -S bridge-utils net-tools

# And most importanly the 

wget http://user-mode-linux.sourceforge.net/uml_utilities_20070815.tar.bz2
bunzip uml_utilities_20070815.tar.bz2 
tar -xvf uml_utilities_20070815.tar
cd tools-20070815 
make 

# The make will error on uml_net/hoct.c:215 undefined 
# reference to ` makedev`   
# this does not really matter, the tunctl binary will be built which we can copy over to /usr/bin like this  

cd tunclt 
sudo cp tunctl /usr/bin

# Make sure you have the /dev/tun node created (it was not by default on the Asahi fresh install) 

sudo mkdir -p /dev/net 
sudo mknod /dev/net/tun c 10 200 

# Then just reboot Asahi for this to work 




# My host networking script for Qemu (bridge)
