[Qemu-devel] [PATCH RFC 00/16] Rework SMP parameters

From: Andrew Jones
Subject: [Qemu-devel] [PATCH RFC 00/16] Rework SMP parameters
Date: Fri, 10 Jun 2016 19:40:11 +0200

This series is a first step in eliminating smp_* global
variables (the last patch gets rid of two of them!) And, it's
a first step in deprecating '-smp' in favor of using machine
properties, e.g.
 qemu -machine pc,sockets=2,cores=2,threads=2,maxcpus=8,cpus=8 ...

It's also a first step in allowing machine types to override
the default parameter parsing, which makes assumptions that
not all machine types may agree with. (mach-virt is coming...)

So, three first steps, I guess that's 3 steps. And a forth
thing it does is some fixes for the smp parsing and also for
SMBIOS use of cpu topology.

Tested with kvm-unit-tests on all five arches supported
there, x86_64 both with KVM and TCG, and booting an x86_64
guest (KVM) to check SMBIOS before and after in order to make
sure it was the same. Also compile tested all targets.


Andrew Jones (15):
  vl: smp_parse: cleanups
  vl: smp: add checks for maxcpus based topologies
  hw/smbios/smbios: fix number of sockets calculation
  hw/core/machine: add smp properites
  vl: move smp parsing to machine pre_init
  qom/cpu: make nr-cores,nr-threads real properties
  hw/core/machine: set cpu global nr_cores,nr_threads in pre_init
  hw/i386/pc: don't use smp_cores,smp_threads
  hw/ppc/spapr: don't use smp_cores,smp_threads
  target-ppc: don't use smp_threads
  hw/arm/virt: rename *.smp_cpus to *.cpus
  hw/arm/virt: don't use smp_cpus,max_cpus
  hw/arm/virt: stash cpu topo info in VirtGuestInfo
  smbios: don't use smp_cores,smp_threads
  sysemu/cpus: bye, bye smp_cores,smp_threads
