[libvirt] [PATCH v2 0/5] introduce support for CPU dies in host/guest topology

Posted by Daniel P. Berrangé 2 weeks ago
Latest generation CPUs (CascadeLake-AP) support a new topology level
known as a 'die', sitting between a socket and a core.

QEMU supports this with -smp arg since 4.1.0

Linux can report this via /sys/devices/system/cpu/cpuNNN/topology
via 'die_id' and 'die_cpus' and 'die_cpus_list' files since 5.2

This series adds support for <topology> in guest XML to have a new
'dies' parameter, passed to QEMU, which defaults to '1' if omitted.

It extends host capabilities so that NUMA topology reports a new
'die_id' attribute

We can't expand 'virNodeInfoPtr' struct to have a die field, so
this will remain forever reporting 'cores' as being 'dies * cores'.

The <topology> in host capabilities XML is an interesting question.

If we are strict with our API semantics we would *not* add a 'dies'
parameter with any value other than '1' to <topology> in the host
capabilities.  If we reported a value other than 1, then any existing
apps which multiple  sockets*cores*threads will get the wrong total
CPU count.

We already know <topology> is broken by design for asymetric
hardware, so we could simply document that it will forever be broken
wrt to CPU dies too.  In this case we might be better to not even
report 'dies=1', just leave out the attr entirely.

Interestingly though, <topology> is already more broken than it
should be. For a VM with   -smp 12,sockets=2,dies=3,cores=2,threads=1
it is reporting <topology sockets=1 dies=1 cores=12 threads=1>.
It should at least do  <topology sockets=2 dies=1 cores=6 threads=1>.

I suspect the presence of dies is confusing the really incredibly
horrible logic in virHostCPUGetInfoLinux. This will also impact
virNodeInfoPtr data.

So even if we don't report dies, I think we still have a bug that
needs fixing here for the coarse node topology.

I'm also confused about what I see with EPYC. IIUC, it was supposed
to use the 'dies' concept, but in machines I've tested, Linux never
reports die count other than 1.  Perhaps only certain EPYC CPU
models or generations use 'dies', or perhaps Linux isn't reporting
correctly for EPYC, or perhaps I'm mislead into believeing it uses
dies.

Anyway, the upshot is I've not found any real hardware to test this
series on. I've tested it only inside a QEMU guest with the suitable
-smp arg to fake dies.

Changed in v2:

 - Fixed docs for dies attribute
 - Improve error checking when parsing
 - Misc typos

Daniel P. Berrangé (5):
  conf: add support for specifying CPU "dies" parameter
  conf: remove unused virCapabilitiesSetHostCPU method
  qemu: add support for specifying CPU "dies" topology parameter
  hostcpu: add support for reporting die_id in NUMA topology
  tests: add host CPU data files for validating die_id
