[Qemu-devel] [PATCH v5 00/10] sPAPR CPU hotplug |
Date: |
Fri, 20 Nov 2015 18:24:29 +0530 |
This patchset adds CPU hotplug support for sPAPR PowerPC guests using
device_add and device_del commands
(qemu) device_add POWER8-powerpc64-cpu,id=cpu0
The first 5 patches are generic changes. Out of these 4/10 is required
by x86 and s390 as well and has been posted in their CPU hotplug patchsets.
I believe 2/10 and 3/10 would be useful for other archs too.
Andreas - If and when found appropriate, would you be taking patches 1 to
5 via your tree ? Should I post them as separate pre-req patchset ?
Patches 6 to 10 are Power specific.
Changes in v5
-------------
- Get rid of a new element (cpu->queued) the previous version introduced
and have the same logic to determine if cpu is already dequeued for
both implementations of cpu_exec_exit(). (2/10)
- Call cpu_remove() from cpu_remove_sync() instead of code duplication. (5/10)
- s/smp_cores/spapr_smp_cores (8/10)
- Set correct tb offset for hotplugged CPU. (8/10)
- s/spapr_hotplug_req_add_event/spapr_hotplug_req_add_by_index (8/10)
- Removed support for incomplete cores and added a separate patch
to prevent such topologies. (8/10 and 1/10)
v4: https://lists.gnu.org/archive/html/qemu-devel/2015-08/msg00650.html
This series applies on top of ppc-for-2.6 branch of David Gibson's tree.
Bharata B Rao (9):
vl: Don't allow CPU toplogies with partially filled cores
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()
xics_kvm: Add cpu_destroy method to XICS
spapr: Enable CPU hotplug for pseries-2.5 and add CPU DRC DT entries
spapr: CPU hotplug support
spapr: CPU hot unplug support
target-ppc: Enable CPU hotplug for POWER8 CPU family
Gu Zheng (1):
cpu: Reclaim vCPU objects
