C++ (Cpp) TPM_BACKEND Examples

Example #1

File: tpm_passthrough.c Project: ChenXuJasper/qemu

static TPMBackend *tpm_passthrough_create(QemuOpts *opts, const char *id)
{
    Object *obj = object_new(TYPE_TPM_PASSTHROUGH);
    TPMBackend *tb = TPM_BACKEND(obj);
    TPMPassthruState *tpm_pt = TPM_PASSTHROUGH(tb);

    tb->id = g_strdup(id);
    /* let frontend set the fe_model to proper value */
    tb->fe_model = -1;

    tb->ops = &tpm_passthrough_driver;

    if (tpm_passthrough_handle_device_opts(opts, tb)) {
        goto err_exit;
    }

    tpm_pt->cancel_fd = tpm_passthrough_open_sysfs_cancel(tb);
    if (tpm_pt->cancel_fd < 0) {
        goto err_exit;
    }

    return tb;
