This trivial rework is aimed to reduce the amount of line changes made by the next patch, when 'def->tpm' will become a 'def->tpms' array. Instead of using a 'switch' where only the VIR_DOMAIN_TPM_TYPE_EMULATOR label does something, use an 'if' clause instead.

A TPM Proxy device can coexist with a regular TPM, but the current domain definition supports only a single TPM device in the 'tpm' pointer. This patch replaces this existing pointer in the domain definition to an array of TPM devices. All files that references the old pointer were adapted to handle the new array instead. virDomainDefParseXML() TPM related code was adapted to handle the parsing of an extra TPM device. TPM validations after this new scenario will be updated in the next patch.

Previous patch handled the conversion of def->tpm to the array def->tpms and the XML parsing logic. This patch handles the validations needed to ensure the intended behavior. The existing qemuValidateDomainDeviceDefTPM() function was updated to guarantee that the VIR_DOMAIN_TPM_MODEL_SPAPR_PROXY model is exclusive to PPC64 guests and to the VIR_DOMAIN_TPM_TYPE_PASSTHROUGH backend. A new function called qemuDomainDefTPMsPostParse() was added to guarantee that the following combinations in the same domain are valid: - a single TPM device - a single TPM Proxy device - a single TPM + single TPM Proxy devices And these combinations in the same domain are NOT valid: - 2 or more TPM devices - 2 or more TPM Proxy devices Tested-by: Satheesh Rajendran <sathnaga(a)linux.vnet.ibm.com&gt; Reviewed-by: Stefan Berger <stefanb(a)linux.ibm.com&gt; Signed-off-by: Daniel Henrique Barboza <danielhb413(a)gmail.com&gt; --- src/qemu/qemu_domain.c | 37 +++++++++++++++++++++++++++++++++++++ src/qemu/qemu_validate.c | 19 +++++++++++++++++++ 2 files changed, 56 insertions(+) diff --git a/src/qemu/qemu_domain.c b/src/qemu/qemu_domain.c index 5de308d285..6586c86a8d 100644 --- a/src/qemu/qemu_domain.c +++ b/src/qemu/qemu_domain.c @@ -4963,6 +4963,40 @@ qemuDomainDefTsegPostParse(virDomainDefPtr def, } +static int +qemuDomainDefTPMsPostParse(virDomainDefPtr def) +{ + virDomainTPMDefPtr proxyTPM = NULL; + virDomainTPMDefPtr regularTPM = NULL; + size_t i; + + if (def->ntpms < 2) + return 0; + + for (i = 0; i < def->ntpms; i++) { + virDomainTPMDefPtr tpm = def->tpms[i]; + + if (tpm->model == VIR_DOMAIN_TPM_MODEL_SPAPR_PROXY) { + if (proxyTPM) { + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", + _("only a single TPM Proxy device is supported")); + return -1; + } else { + proxyTPM = tpm; + } + } else if (regularTPM) { + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, "%s", + _("only a single TPM non-proxy device is supported")); + return -1; + } else { + regularTPM = tpm; + } + } + + return 0; +} + + static int qemuDomainDefPostParseBasic(virDomainDefPtr def, void *opaque G_GNUC_UNUSED) @@ -5049,6 +5083,9 @@ qemuDomainDefPostParse(virDomainDefPtr def, if (qemuDomainDefTsegPostParse(def, qemuCaps) < 0) return -1; + if (qemuDomainDefTPMsPostParse(def) < 0) + return -1; + return 0; } diff --git a/src/qemu/qemu_validate.c b/src/qemu/qemu_validate.c index b1a81ab193..f77030bd46 100644 --- a/src/qemu/qemu_validate.c +++ b/src/qemu/qemu_validate.c @@ -3655,6 +3655,25 @@ qemuValidateDomainDeviceDefTPM(virDomainTPMDef *tpm, case VIR_DOMAIN_TPM_MODEL_SPAPR: flag = QEMU_CAPS_DEVICE_TPM_SPAPR; break; + case VIR_DOMAIN_TPM_MODEL_SPAPR_PROXY: + if (!ARCH_IS_PPC64(def->os.arch)) { + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, + _("TPM Proxy model %s is only available for " + "PPC64 guests"), + virDomainTPMModelTypeToString(tpm->model)); + return -1; + } + + /* TPM Proxy devices have 'passthrough' backend */ + if (tpm->type != VIR_DOMAIN_TPM_TYPE_PASSTHROUGH) { + virReportError(VIR_ERR_CONFIG_UNSUPPORTED, + _("TPM Proxy model %s requires " + "'Passthrough' backend"), + virDomainTPMModelTypeToString(tpm->model)); + } + + flag = QEMU_CAPS_DEVICE_SPAPR_TPM_PROXY; + break; case VIR_DOMAIN_TPM_MODEL_LAST: default: virReportEnumRangeError(virDomainTPMModel, tpm->model); -- 2.26.2

This tests aims to exercise how a TPM Proxy device can be added in the domain, either alone or with a regular TPM device. It also ensures that we do not allow bogus scenarios to slip by.

This patch wraps it up all the wiring done in previous patches, enabling a PPC64 guest to launch a guest using a TPM Proxy device. Note that device validation is already being done in qemu_validate.c, qemuValidateDomainDeviceDefTPM(), on domain define time. We don't need to verify QEMU capabilities for this device again inside qemu_command.c.
