This should be mentioned in docs/system/removed-features.rst... but, wait, I don't see anything for it in docs/system/deprecated.rst. This is dropping a feature without following the usual deprecation policy, i.e. marking the feature as deprecated and only remove it 2 QEMU versions later. Any justification for that ? David, Unrelated, I saw that you already applied this to ppc-for-6.1 on gitlab but the commit title appears to be broken: '65;6401;1cmonitor: removed cpustats command https://gitlab.com/dgibson/qemu/-/commit/532be563eae6b8ae834ff7e9ebb1428f53= 569a69 > Suggested-by: Richard Henderson > Signed-off-by: Bruno Larsen (billionai) > --- > hmp-commands-info.hx | 13 ------------- > monitor/misc.c | 11 ----------- > 2 files changed, 24 deletions(-) >=20 > diff --git a/hmp-commands-info.hx b/hmp-commands-info.hx > index ab0c7aa5ee..b2347a6aea 100644 > --- a/hmp-commands-info.hx > +++ b/hmp-commands-info.hx > @@ -500,19 +500,6 @@ SRST > Show the current VM UUID. > ERST > =20 > - { > - .name =3D "cpustats", > - .args_type =3D "", > - .params =3D "", > - .help =3D "show CPU statistics", > - .cmd =3D hmp_info_cpustats, > - }, > - > -SRST > - ``info cpustats`` > - Show CPU statistics. > -ERST > - > #if defined(CONFIG_SLIRP) > { > .name =3D "usernet", > diff --git a/monitor/misc.c b/monitor/misc.c > index f3a393ea59..1539e18557 100644 > --- a/monitor/misc.c > +++ b/monitor/misc.c > @@ -369,17 +369,6 @@ static void hmp_info_history(Monitor *mon, const QDi= ct *qdict) > } > } > =20 > -static void hmp_info_cpustats(Monitor *mon, const QDict *qdict) > -{ > - CPUState *cs =3D mon_get_cpu(mon); > - > - if (!cs) { > - monitor_printf(mon, "No CPU available\n"); > - return; > - } > - cpu_dump_statistics(cs, 0); > -} > - > static void hmp_info_trace_events(Monitor *mon, const QDict *qdict) > { > const char *name =3D qdict_get_try_str(qdict, "name");
