This patch set provides the initial implementation of support for the
POWER9 processor running in tcg mode under the pseries machine type.
To use a POWER9 cpu provide the command line option "-cpu POWER9".
This is the initial work to make the mmu emulation model look like a POWER9
Currently only legacy kernels are supported (hash without segment tables).
This patch set will be followed by two more in the near future to support
the new process table capabilities added in ISAv3.00; hash via segment
tables and radix. Kernels with support for this will currently fail when
they try to register a process table as this isn't yet implemented.
The assumption is that we're running a legacy kernel, in the event the
guest registers a process table (when support exists) we will handle it
accordingly.
The main changes are:
- Define a new mmu model and fault handler
- Add new LPCR fields and check them accordingly
- Add a partition table entry to the machine state
- Point to the partition table entry in the cpu state
- Remove SDR1
- Adapt to new pte format
- NOOP the cp_abort instruction
- Small bug fixes
This was intially one huge patch so I've tried to break it up into what I
think are logical chunks, how exactly this should be split up is up for
debate.
A current upstream kernel with POWER9 support added to the architecture
vector should correctly report a POWER9 cpu under /proc/cpuinfo.
