Hi,
This is an early RFC patchset that adds CPU hotplug support for sPAPR guests.
The patchset applies on top of spapr-pci-hotplug-ppc-next-cleanup4 branch
of Michael Roth's tree (git://github.com/mdroth/qemu). I realize that Michael's
branch is a fast moving target and is under review now, but my patchset
depends on the hotplug framework that Michael is adding.
The division of the patches might look artificial at places, that's because
I have tried to separate the cleanup vs the actual changes I am adding. Also
there are a few fixes (like endianness fixes) that probably could be part
of Michael's patchset itself.
With the current patchset, I am able to hotplug CPUs to a BE guest successfully.
There are issues with LE guest which I still need to resolve. The hotplug
semantics (adding CPU vs adding core) hasn't yet been finalized and I have
described this issue in the patch 15/15. Also this needs a few endian
fixes to PowerPC kernel (in the CPU hotplug code path), which I will be
posting later separately.
Bharata B Rao (15):
ppc: Store dr entity state bits at the right bit offset
ppc: Rename SPAPR_DRC_TABLE_SIZE to SPAPR_DRC_PHB_TABLE_SIZE
ppc: Rename sPAPRDrcEntry.phb_buid to sPAPRDrcEntry.id
ppc: Make creation of DRC entries in FDT endian safe
ppc: Accommodate CPU DRC entries in DRC table
ppc: stop after getting first unused DR slot in DRC table
ppc: Initialize DRC table before initializing CPUs
ppc: Add CPU dynamic reconfiguration (DR) support
ppc: Consider max_cpus during xics initialization
ppc: Factor out CPU initialization code to a new routine
ppc: Move RTAS indicator defines to a header file
ppc: Support ibm,lrdr-capacity device tree property
ppc: Make ibm,configure-connector endian-safe
ppc: Add CPU hotplug support for sPAPR guests
ppc: Allow hotplugging of CPU cores only
