[libvirt PATCH 3/5] qemu: Default to TPM 2.0 for ARM virt guests

The TPM 2.0 specification predates ARM virtualization, and so implementing TPM 1.2 support on ARM was not considered a useful endeavor. This is technically a breaking change, but TPM support on ARM was only introduced fairly recently (libvirt 7.1.0) and the previous default resulted in non working TPM devices; anyone who has a working configuration is not going to be affected. https://bugzilla.redhat.com/show_bug.cgi?id=1970310 Signed-off-by: Andrea Bolognani <abologna(a)redhat.com&gt; --- src/qemu/qemu_domain.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/src/qemu/qemu_domain.c b/src/qemu/qemu_domain.c index fc60e15eea..8488f58e09 100644 --- a/src/qemu/qemu_domain.c +++ b/src/qemu/qemu_domain.c @@ -4445,7 +4445,8 @@ qemuDomainDefTPMsPostParse(virDomainDef *def) /* TPM 1.2 and 2 are not compatible, so we choose a specific version here */ if (tpm->version == VIR_DOMAIN_TPM_VERSION_DEFAULT) { if (tpm->model == VIR_DOMAIN_TPM_MODEL_SPAPR || - tpm->model == VIR_DOMAIN_TPM_MODEL_CRB) + tpm->model == VIR_DOMAIN_TPM_MODEL_CRB || + qemuDomainIsARMVirt(def)) tpm->version = VIR_DOMAIN_TPM_VERSION_2_0; else tpm->version = VIR_DOMAIN_TPM_VERSION_1_2; -- 2.31.1
