In addition to usual CPUID bits, some CPU features started to be
reported in IA32_ARCH_CAPABILITIES MSR. This series adds support for
such CPU features.
However, the last patch which actually adds definitions for some MSR
features to the cpu_map should not be pushed yet as the QEMU interface
for MSR features is not complete yet. If a domain with some MSR features
enabled would be started, all of them would be marked as disabled in the
live domain configuration (even though they were actually enabled by
QEMU) and they would disappear during migration.

New subject: [libvirt] [PATCH 04/36] cpu_x86: Do not cache microcode version
The microcode version checks are used to invalidate cached CPU data we
get from QEMU. To minimize /proc/cpuinfo parsing the microcode version
was only read when libvirtd started and cached for the daemon's
lifetime. However, the CPU microcode can change anytime (updating the
microcode package can automatically upload it to the CPU) and we need to
stop caching it to avoid using stale CPU model data.

Hmm, I realized I didn't do a good job in ordering the first few patches
in this series as patches 1, 4, and 5 are quite unrelated to the
refactoring and MSR features. I'll just push them while waiting for
reviews for the rest of the series.
Thanks, Jirka.

New subject: [libvirt] [PATCH 06/36] cpu_x86: Introduce virCPUx86DataItem container struct
The following patches introduce CPU features read from MSR in addition
to those queried via CPUID instruction. Let's introduce a container
struct which will be able to describe either feature type.

The following patches introduce CPU features read from MSR in
addition
to those queried via CPUID instruction. Let's introduce a container
struct which will be able to describe either feature type.

Although vendor string is always reported by CPUID, the container struct
is used for consistency and thus "cpuid" name is not a good fit anymore.

We don't really need to parse CPU data from QEMU older than 2.9 (i.e.,
before query-cpu-model-expansion) at this point. But even if there's a
need to do so, we can always use an older version of this script to do
the conversion.

before query-cpu-model-expansion) at this point. But even if there's a
need to do so, we can always use an older version of this script to do
the conversion.

New subject: [libvirt] [PATCH 31/36] cputest: Add support for MSR features to cpu-gather.sh
This patch adds an inline python code for reading MSR features. Since
reading MSRs is a privileged operation, we have to read them from
/dev/cpu/*/msr if it is readable (i.e., the script runs as root) or
fallback to using KVM ioctl which can be done by any user that can start
virtual machines.
The python code is inlined rather than provided in a separate script
because whenever there's an issue with proper detection of CPU features,
we ask the reporter to run cpu-gather.sh script to give us all data we
need to know about the host CPU. Asking them to run several scripts
would likely result in one of them being ignored or forgotten.

The new virHostCPUGetMSR internal API will try to read the MSR from
/dev/cpu/0/msr and if it is not possible (the device does not exist or
libvirt is running unprivileged), it will fallback to asking KVM for the
MSR using KVM_GET_MSRS ioctl.

Is there benefit to using /dev/cpu/0/msr, instead of always using
/dev/kvm ?

KVM may report some bits in the IA32_ARCH_CAPABILITIES MSR even when the
host does not set them or even support MSR at all. So for reporting host
capabilities /dev/cpu/0/msr is IMHO better. We will still get the made
up bits in the MSR via QEMU for host-model.
For example, on my laptop which does not support IA32_ARCH_CAPABILITIES
MSR at all I get 0x8 when asking KVM, while reading /dev/cpu/0/msr
returns I/O error since the MSR does not exist.

KVM may report some bits in the IA32_ARCH_CAPABILITIES MSR even when the
host does not set them or even support MSR at all. So for reporting host
capabilities /dev/cpu/0/msr is IMHO better. We will still get the made

Hmm, do we need to get /dev/kvm fixed in this regard ? It seems bad that
libvirt will be relying on different information about MSRs when running
as root vs non-root. Could like to even more painful bugs to triage.

Daniel

as root vs non-root. Could like to even more painful bugs to triage.
Hmm, actually we read any of those only if the corresponding CPUID bit
is set, that is when the host CPU supports this MSR. So the problem with
reading something from KVM when the MSR is not supported does not exist.
However, we can still see more bits enabled when reading the MSR via
KVM. So when libvirtd is unprivileged, it will show MSR features which
can be emulated by KVM even in host capabilities (while normally we
would only see them in domain capabilities). I don't think this should
be a big deal. But I still think it's better to show the real results
read from the host CPU when possible.

Yep, it breaks the build on my arm box too. MSRs are specific to x86. I
guess we need to put some more #ifdef-s in. Let me see if I can cook a
patch.

Using virResetLastError in a place other than starting a public API

If we're ignoring the error, we should not have logged it in the first

New subject: [libvirt] [PATCH 36/36] cpu_map: Introduce IA32_ARCH_CAPABILITIES MSR features
---
This should not be pushed yet as the QEMU interface for MSR features is
not complete yet. If a domain with some MSR features enabled would be
started, all of them would be marked as disabled in the live domain
configuration (even though they were actually enabled by QEMU) and they
would disappear during migration.
