==== run
....
./run [OPTIONS] [-- EXTRA_RUN_ARGS]
....
`EXTRA_RUN_ARGS` gets appended to the end of the emulator command line.
[options="header"]
|===
|Name |Argument name |Description
|`-c` |`NCPUS` |Emulate `NCPUS` guest CPUs.
|`-D` | |Run GDB on the emulator itself.
|`-d` | |Wait for GDB to connect before starting execution.
|`-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` |`CMDSTR` |Much like `-f`, but base64 encodes the string.
Mnemonic: `-F` is to `-f` what `-E` is to `-e`.
|`-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`
|`-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.
|`-L` |`VARIANT` |Linux kernel build variant.
|`-l` |`CHECKPOINT` |Restore the nth most recently taken gem5 checkpoint according to
directory timestamps.
|`-M` |`VARIANT` |gem5 build output variant.
|`-m` | |Set the memory size of the guest. E.g.: `-m 512M`. Default: `256M`.
The default is the minimum amount that boots all archs without extra
options added. Anything lower will lead some arch to fail to boot.
Any
|`-R` | |Replay a QEMU run record deterministically.
|`-r` | |Record a QEMU run record for later replay with `-R`.
|`-P` | |Run the downloaded prebuilt images.
|`-Q` |`VARIANT`` |QEMU build variant.
|`-T` |`TRACE_TYPES` |Set trace events to be enabled.
If not given, gem5 tracing is completely disabled, while QEMU tracing
is enabled but uses default traces that are very rare and don't affect
performance. `./configure --enable-trace-backends=simple` seems to enable
some traces by default, e.g. `pr_manager_run`, and I don't know how to
get rid of them.
|`-U` | |Pass extra parameters to the program running on the `-u` tmux split.
|`-u` | |Create a tmUx split the window.
You must already be inside of a `tmux` session to use this option.
* on the main window, run the emulator as usual
* on the split:
** if on QEMU and `-d` is given, GDB
** if on gem5, the gem5 terminal
|`-V` | |Run QEMU with VNC instead of the default SDL.
Connect to it with: `vinagre localhost:5900`.
|`-X` |`EXTRA_OPTS` |Extra options that did not fit into `A-z`!
This string is parsed by `getopt` on a separate parse step with different
meanings for each flag.
|`-X-b` | |Use `fs_bigLITTLE.py` instead of `fs.py` on gem5 simulation.
Ignored by QEMU.
|`-x` | |Run in graphic mode. Mnemonic: X11.
