24.8.1.4. m5 writefile

Send a guest file to the host. 9P is a more advanced alternative.

Guest:

echo mycontent > myfileguest
m5 writefile myfileguest myfilehost

Host:

cat "$(./getvar --arch aarch64 --emulator gem5 m5out_dir)/myfilehost"

Does not work for subdirectories, gem5 crashes:

m5 writefile myfileguest mydirhost/myfilehost
