[Qemu-devel] [QEMU-PPC] [PATCH V2 00/10] target/ppc: Implement POWER9 pseries tcg

[Suraj Jitindar Singh <sjitindarsingh@gmail.com>]

This is V2 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 will be followed shortly by one to implement radix support and
currently trying to boot a kernel with support for radix with this series
will fail on the H_REGISTER_PROCESS_TABLE hcall.

The changes from V1 are as follows:

 - Drop patches which have already been merged.
 - Instead of allocating a whole partition table we allocate a single
   entry in the sPAPRMachineState and access it via the virtual hypv.
 - Changes to how we handle SDR1 and renaming of associated functions.
 - Drop patch to use the new pte format, guest kernels expect the old
   format anyway, so this will only be applicable when POWER9 powernv
   support is added, so delay adding support for this until then.
 - Rename the mmu fault handler to ppc64_v3_handle_mmu_fault.
 - Move segment table searching into the fault handler instead of in
   slb_lookup().
 - Move adding the POWER9 pseries cpu model to the end of the series.
