|
|
|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_lala=y'`
|
|
Mnenomic: comes after `-e`.
|
|
|`-G` | |Pass extra options to the gem5 executable.
|
|
Do not confuse with the arguments passed to config scripts,
|
|
like `fs.py`. Example: `./run -G '--debug-flags=Exec --debug' -g`
|
|
|`-g` | |Use gem5 instead of QEMU.
|
|
|`-h` | |Show this help message.
|
|
|`-I` | |Run with initramfs.
|
|
|`-i` | |Run with initrd.
|
|
|`-K` | |Use KVM. Only works if guest arch == host arch.
|
|
|`-k` | |Enable KGDB.
|
|
|`-m` | |Set the memory size of the guest. E.g.: `-m 512M`. Default: `256M`.
|
|
The default is the minimum ammount that boots all archs without extra
|
|
options added. Anything lower will lead some arch to fail to boot.
|
|
Any
|
|
|`-T` | |Enable extra QEMU trace events.
|
|
`./configure --enable-trace-backends=simple` seems to enable
|
|
some by default, e.g. `pr_manager_run`, and I don't know how to
|
|
get rid of them. But those events are rare and should not impact
|
|
performance, so we just ignore them for now.
|
|
|`-V` | |Run QEMU with VNC instead of the default SDL.
|
|
Connect to it with: `vinagre localhost:5900`.
|
|
|`-x` | |Run in graphic mode. Mnemonic: X11.
