This is necessary because qemu and gem5 now use the same build folder. Separate ./run -e and -f for kernel options before and after the ' - '. This was already the better thing to do when -E was introduced, but lkmc_nonet prompted me to do it nicer now. Use the common script to find the out_dir on every toplevel script. Include usage man pages on README.

|
|Name |Argument name | Description
|
|
|`-a` |`ARCH` | Run architecture `ARCH`.
|
|
|`-c` |`NCPUS` | Emulate `NCPUS` guest CPUs.
|
|
|`-D` | | Run GDB on the emulator itself.
|
|
|`-d` | | Run in debug mode, expect a GDB connection to guest.
|
|
|`-E` |`CMDSTR` | Replace the normal init with a minimal init that just evals
|
|
with given `CMDSTR` bash command string. Example:
|
|
`-E 'insmod /hello.ko;'`
|
|
|`-e` |`CLI_OPTIONS` | Pass an extra Linux kernel command line options,
|
|
and place them before the dash separator `-`.
|
|
Only options that come before the `-`, i.e. "standard"
|
|
options, should be passed with this option.
|
|
Example: `./run -a arm -e 'init=/poweroff.out'`
|
|
|`-f` |`CLI_OPTIONS` | Pass an extra Linux kernel command line options,
|
|
add a dash `-` separator, and place the options after the dash.
|
|
Intended for custom options understood by our `init` scripts,
|
|
most of which are prefixed by `lkmc_`, e.g.:
|
|
`./run -f 'lkmc_eval="wget google.com" lkmc_nonet=y'`
|
|
Mnenomic: comes after `-e`.
|
|
|`-K` | | Use KVM. Only works if guest arch == host arch.
|
|
|`-k` | | Enable KGDB.
|
|
|`-G` | | Pass extra options to the gem5 executable.
|
|
Only useful if `-g` is given.
|
|
Do not confuse with the arguments passed to the config scripts,
|
|
e.g. `fs.py`
|
|
|`-h` | | Show this help message.
|
|
|`-I` | | Run with initramfs.
|
|
|`-i` | | Run with initrd.
|
|
|`-m` | | Set the memory size of the guest. E.g.: `-m 512M`. Default: `256M`.
|
|
|`-n` | | Run in nographic mode.
