target/i386/sev: Move qmp_sev_inject_launch_secret() to sev.c
Move qmp_sev_inject_launch_secret() from monitor.c to sev.c
and make sev_inject_launch_secret() static. We don't need the
stub anymore, remove it.
Previously with binaries built without SEV, management layer
was getting an empty response:
{ "execute": "sev-inject-launch-secret",
"arguments": { "packet-header": "mypkt", "secret": "mypass", "gpa": 4294959104 }
}
{
"return": {
}
}
Now the response is explicit, mentioning the feature is disabled:
{ "execute": "sev-inject-launch-secret",
"arguments": { "packet-header": "mypkt", "secret": "mypass", "gpa": 4294959104 }
}
{
"error": {
"class": "GenericError",
"desc": "this feature or command is not currently supported"
}
}
