[Qemu-devel] [RFC PATCH v2.1 00/12] Core based CPU hotplug for PowerPC sPAPR |

Hi,
This is v2.1 of "Core based CPU hotplug for PowerPC sPAPR". v2 was posted
here: https://lists.gnu.org/archive/html/qemu-ppc/2016-03/msg00201.html
I am making this v2.1 instead of v3 as this introduces a change in
device_add semantics and if we don't want to continue this, I will go back
to the previous v2 semantics from v3 onwards. v2 had spapr-cpu-core device
that served as CPU core device for all types of PowerPCCPU threads.
In this version however, spapr-cpu-core becomes an abstract device and we
will have different core devices for each of the PowerPCCPU type. So
in this version, the hotplug semantics looks like this:
(qemu) device_add POWER8-spapr-cpu-core,id=core2,core=16[,threads=4]
cpu_model specification is gone as it becomes redundant with different
core types for each CPU type. CPU core types are defined only for
host, POWER7 and POWER8 models only (and not for their variants/aliases)
yet.
I have mostly taken care of all the review comments that I got for v2.
Major changes in this version (v2.1)
------------------------------------
- Semantics change: spapr-cpu-core to POWER8-spapr-cpu-core and likewise
- Included Igor's pre_plug patch.
Bharata B Rao (10):
exec: Remove cpu from cpus list during cpu_exec_exit()
exec: Do vmstate unregistration from cpu_exec_exit()
cpu: Add a sync version of cpu_remove()
cpu: Abstract CPU core type
spapr: Abstract CPU core device
spapr: Add CPU type specific core devices
spapr: convert boot CPUs into CPU core devices
spapr: CPU hotplug support
xics,xics_kvm: Handle CPU unplug correctly
spapr: CPU hot unplug support
Gu Zheng (1):
cpu: Reclaim vCPU objects
Igor Mammedov (1):
qdev: hotplug: Introduce HotplugHandler.pre_plug() callback
