qemu-e2k/hmp-commands-info.hx
Emilio G. Cota 97bfafe28a hmp-commands-info: add sync-profile 
The command introduced here is just for developers. This means that:

- the info displayed and the output format could change in the future
- the command is only meant to be used from HMP, not from QMP

Sample output:

(qemu) sync-profile
sync-profile is off
(qemu) info sync-profile
