[Qemu-devel] [QEMU-PPC] [PATCH V3 00/10] target/ppc: Implement POWER9 pseries tcg legacy support

[Suraj Jitindar Singh]

This is V3 of the patch series to implement tcg emulation support for a
POWER9 cpu model for the pseries machine type running a legacy kernel.
That is a kernel which doesn't use the new radix mmu mode or the new hash
mmu mode with segment tables.

To use a POWER9 cpu provide the command line option "-cpu POWER9".

This series attempts to avoid precluding KVM-HV support for the POWER9
cpu model but doesn't attempt to support KVM-PR or the powernv machine
for the POWER9 cpu model as these aren't currently supported or
implemented and further code changes will be required in the event these
are implemented.

This series is used as a base to implement radix support.

The changes from V2 are as follows:

 - Only migrate the partition table entry on non-zero value
 - Change how register generation works to simplify adding/removing
   registers
 - Rename mmu.h -> mmu-book3s-v3.h
 - Error report and abort on attempt to use segment tables
