When the management layer queries a binary built using --disable-tpm
for TPM devices, it gets confused by getting empty responses:
{ "execute": "query-tpm" }
{
"return": [
]
}
{ "execute": "query-tpm-types" }
{
"return": [
]
}
{ "execute": "query-tpm-models" }
{
"return": [
]
}
To make it clearer by returning an error:
- Make the TPM QAPI schema conditional
All of tpm.json is now 'if': 'defined(CONFIG_TPM)'.
- Adapt the HMP command
- Remove stubs which became unnecessary
The management layer now gets a 'CommandNotFound' error:
{ "execute": "query-tpm" }
{
"error": {
"class": "CommandNotFound",
"desc": "The command query-tpm has not been found"
}
}
