[PATCH] tpm: Return QMP error when TPM is disabled in build |
Date: |

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": [
]
}
Make it clearer by returning an error, mentioning the feature is
disabled:
{ "execute": "query-tpm" }
{
"error": {
"class": "GenericError",
"desc": "this feature or command is not currently supported"
}
}
