[PATCH] qemu: Enable I/O APIC even more frequently
by Michal Privoznik 18 Dec '24

18 Dec '24

In my previous commit v10.10.0-48-g2d222ecf6e I've made us enable I/O APIC when there is an IOMMU with EIM. This works well. What does not work is case when there's just an IOMMU without EIM but with 256+ vCPUS. Problem is that post parsing happens in two stages: general domain post parse (where qemuDomainDefEnableDefaultFeatures() is called) and then per device post parse (where qemuDomainIOMMUDefPostParse() is called). Now, in aforementioned case it is the device post parse phase where EIM is enabled but the code that would enable VIR_DOMAIN_FEATURE_IOAPIC has already run. To resolve this, make the domain post parse callback "foresee" the future enabling of EIM so that it can turn on I/O APIC beforehand. Resolves: https://issues.redhat.com/browse/RHEL-65844 Fixes: 2d222ecf6e73614a400b830ac56e9aaa1bc55ecc Signed-off-by: Michal Privoznik <mprivozn(a)redhat.com> --- src/qemu/qemu_postparse.c | 21 +++++++++--- ...m-autoadd-v2.x86_64-latest.abi-update.args | 1 + ...im-autoadd-v2.x86_64-latest.abi-update.xml | 1 + .../intel-iommu-eim-autoadd-v2.xml | 32 +++++++++++++++++++ tests/qemuxmlconftest.c | 1 + 5 files changed, 51 insertions(+), 5 deletions(-) create mode 120000 tests/qemuxmlconfdata/intel-iommu-eim-autoadd-v2.x86_64-latest.abi-update.args create mode 120000 tests/qemuxmlconfdata/intel-iommu-eim-autoadd-v2.x86_64-latest.abi-update.xml create mode 100644 tests/qemuxmlconfdata/intel-iommu-eim-autoadd-v2.xml diff --git a/src/qemu/qemu_postparse.c b/src/qemu/qemu_postparse.c index 4fbd849ebf..34b95ece1b 100644 --- a/src/qemu/qemu_postparse.c +++ b/src/qemu/qemu_postparse.c @@ -783,6 +783,15 @@ qemuDomainPstoreDefPostParse(virDomainPstoreDef *pstore, } +static bool +qemuDomainNeedsIOMMUWithEIM(const virDomainDef *def) +{ + return ARCH_IS_X86(def->os.arch) && + virDomainDefGetVcpusMax(def) > QEMU_MAX_VCPUS_WITHOUT_EIM && + qemuDomainIsQ35(def); +} + + static int qemuDomainIOMMUDefPostParse(virDomainIOMMUDef *iommu, const virDomainDef *def, @@ -793,9 +802,7 @@ qemuDomainIOMMUDefPostParse(virDomainIOMMUDef *iommu, * (EIM) is not explicitly turned off, let's enable it.

[PATCH 0/3] Addng POWER11 cpu support
by Narayana Murty N 17 Dec '24

17 Dec '24

This patch series includes the changes needed to support POWER11 cpu and POWER11 host on libvirt. Patch also adds and updates the qemu caps with the latest qemu for the caps tests to include POWER11. Patch 0001: Add POWER11 cpu model support. Patch 0002: Add POWER11 host model support. Patch 0003: Add qemu and domain test capabilities test support. The respective patches for linux kernel and qemu already in upstream and links are provided below. Linux kernel patches: 1. Linux P11 support: commit id c2ed087ed35c ("powerpc: Add Power11 architected and raw mode") 2. Linux P11 KVM support: commit id 96e266e3bcd6 ("KVM: PPC: Book3S HV: Add Power11 capability support for Nested PAPR guests") Qemu patches: 3. Qemu P11 support: commit id 273db89bcaf4 ("ppc/pseries: Add Power11 cpu type) 4.

[PATCH v3 0/7] Allow Guest CPU Model with Deprecated Features Disabled
by Collin Walling 17 Dec '24

17 Dec '24

# Changelog v3 - added reviewed-by's on appropriate patches - split patch #4 into three: - domain API (libvirt-domain: introduce VIR_CONNECT_GET_DOMAIN_CAPABILITIES_DISABLE_DEPRECATED_FEATURES) - qemu (qemu_capabilities: filter deprecated features if requested) - virsh (virsh: add --disable-deprecated-features flag to domcapabilities) - Note: no functional change, patches were split based on changes to certain files - @Jiri, let me know if this is what you had in mind, I found it difficult to find a good reference - fixed deprecated_props array missing +1 in qemuJSONMonitor* functions - condensed cputypes schema for deprecated_features - added validation in qemu_process to check if QEMU cap is present - added qemuxmlconf tests - updated version tags to 11.0.0 v2 - rebased on latest master changes # Description Add support for libvirt to query and cache an array of deprecated CPU features (aka CPU properties) for the host-model. This data is queried via a full query-cpu-model-expansion and cached in the QEMU capabilities file. This model expansion will depend on the availability of the "deprecated-props" field resulting from a query-cpu-model-expansion command. Currently, only s390x supports this field. The purpose of these patches is to make it easy for users to create guests with a CPU model that will be compatible & migratable with future hardware. An updated host CPU model with deprecated features paired with the policy "disable" may be visable via an update to the virsh domcapabilities command with the --disable-deprecated-features flag. An example is shown below. Note: other CPU model queries (e.g. baseline and comparison) currently do not consider deprecated features, as their outputs do not consider feature policy. If implementation is desired, it will require a discussion on how these commands should report policies. Examples: virsh domcapabilities --disable-deprecated-features e.g. output (trimmed): <mode name='host-model' supported='yes'> <model fallback='forbid'>z14.2-base</model> <feature policy='require'

[PATCH] rpm: ensure we own directories we might create
by Daniel P. Berrangé 17 Dec '24

17 Dec '24

An RPM must own any directories its creates, unless it can guarantee a dependancy has ownership. Two packages owning the same directory is fine if permissions are consistent. We don't require augeas as a dep in most packages, so we must own the augeas lens directories. Likewise for systemtap tapset dirs. Our own cpu map dir also needs ownership. A few files are re-sorted, so that the files are listed immediately adjacent to the %dir that contains them. https://bugzilla.redhat.com/show_bug.cgi?id=2280979 Signed-off-by: Daniel P.

[PATCH] qemu: Enable I/O APIC if needed
by Michal Privoznik 16 Dec '24

16 Dec '24

This is a follow up of my previous commits. If the number of vCPUs exceeds some arbitrary value (255) then QEMU requires IOMMU with EIM and interemap enabled. But in turn, intremap IOMMU requires split I/O APIC (per virDomainDefIOMMUValidate()). Since after my previous commits (e.g. v10.10.0-rc1~183) IOMMU is added automagically, the I/O APIC can be also enabled automagically.
