So with the necessary filtering this will then have to be -device
tpm-tis,tpmdev=tpm0,id=tpm0 . I am not sure whether there is a better
way of doing this. If there is, can someone please let me know? I need
tpmdev=tpm0 to fill the Properties of the tpm_tis driver, which it
uses to find the backend with the above 'id=tpm0'.For the hmp and qmp
code to display the proper data and filter the above mention case I
would then use the following patch:
[...]
TPMInfoList *info, *head = NULL, *cur_item = NULL;
QLIST_FOREACH(drv, &tpm_backends, list) {
+ if (!tpm_find_frontend(drv->id)) {
+ continue;
+ }
info = g_new0(TPMInfoList, 1);
info->value = qmp_query_tpm_inst(drv);
I need to use 'tpm0' as search key in qemu_find_opts() which in turn
requires that the device has id=tpm0 given.
Argh, DeviceState's id holds the id of the device. So this got a lot
simpler and -device tpm-tis,tpmdev=tpm0,... is not needed anymore, but
now it should be -device tpm-tis,id=tpm
