ppc patch queue for 2022-07-18:

This is the last ppc patch queue before the soft freeze. It contains new
TCG instructions and changes, a tricky bug fix in kvmppc_find_cpu_dt()
and other enhancements/fixes.

- tcg and target/ppc:
- move instructions to decodetree
- check for bad Radix configs
- ISA 3.00 tlbie[l]
- fix gen_*_exception error codes
- check fortb_env != 0 when printing TBU/TBL/DECR
- fix kvmppc_find_cpu_dt() returning the wrong CPU DT path when there's a
'clock-frequency' property in the root node
- spapr, e500: pass a random seed in /chosen/rng-seed
- all boards: allocate IRQ lines with qdev_init_gpio_in()

ppc patch queue 2021-07-09

Here's a (probably) final pull request before the qemu-6.1 soft
freeze. Includes:
* Implementation of the new H_RPT_INVALIDATE hypercall
* Virtual Open Firmware for pSeries and pegasos2 machine types.
This is an experimental minimal Open Firmware implementation which
works by delegating nearly everything to qemu itself via a special
hypercall.
* A number of cleanups to the ppc soft MMU code
* Fix to handling of two-level radix mode translations for the
powernv machine type
* Update the H_GET_CPU_CHARACTERISTICS call with newly defined bits.
This will allow more flexible handling of possible future CPU
Spectre-like flaws
* Correctly treat mtmsrd as an illegal instruction on BookE cpus
* Firmware update for the ppce500 machine type

ppc patch queue 2019-02-26

Next set of patches for ppc and spapr. There's a lot in this one:
* Support "STOP light" states on POWER9
* Add support for HVI interrupts on POWER9 (powernv machine)
* CVE-2019-8934: Don't leak host model and serial information to the guest
* Tests and cleanups for various hot unplug options
* Hash and radix MMU implementation on POWER9 for powernv machine
* PCI Host Bridge hotplug support for pseries machine
* Allow larger kernels and initrds for powernv machine

Plus a handful of miscellaneous fixes and cleanups.

The cpu hotplug tests and cleanups from David Hildenbrand aren't
solely power related. However the consensus amongst Michael Tsirkin,
David Hildenbrand, Cornelia Huck and myself was that it made most
sense to come in via my tree.

Merge remote-tracking branch 'dgibson/tags/ppc-for-2.10-20170511' into staging

ppc patch queue for 2017-05-11

This pull request supersedes the one from yesterday (20170510), fixing
an important style bug in one patch, and adding an extra couple of
simple patches.

Highlights of this set:
* Some fixes for POWER9
* TCG support for POWER9 radix MMU
* VGA rom for Mac machine types
* Fixes for the XICS interrupt controller
* MTTCG support for ppc targets

As suggested by Paolo, I've tried to add the Docker tests to my
standard pre-pull-request tests. I haven't wholly suceeded; this has
been tested with some of the Docker images, but others I haven't
managed due to problems that as best I can tell are not due to
problems in this patch series. I'll continue working on this for
future pull requests. Specifically, 'travis', 'fedora', and 'centos6'
seem to work. 'min-glib' jammed while gtesting moxie, which seems
very unlikely to be caused by this series. 'ubuntu', 'debian' and
'debian-bootstrap' hit build errors almost immediately that look like
problems with the container configuration, and 'debian-*-cross' hit
build errors later on which also look like missing dependencies from
the container.

target/ppc: Implement ISA V3.00 radix page fault handler

ISA V3.00 introduced a new radix mmu model. Implement the page fault
handler for this so we can run a tcg guest in radix mode and perform
address translation correctly.

In real mode (mmu turned off) addresses are masked to remove the top
4 bits and then are subject to partition scoped translation, since we only
support pseries at this stage it is only necessary to perform the masking
and then we're done.

In virtual mode (mmu turned on) address translation if performed as
follows:

1. Use the quadrant to determine the fully qualified address.

The fully qualified address is defined as the combination of the effective
address, the effective logical partition id (LPID) and the effective
process id (PID). Based on the quadrant (EA63:62) we set the pid and lpid
like so:

quadrant 0: lpid = LPIDR, pid = PIDR
quadrant 1: HV only (not allowed in pseries)
quadrant 2: HV only (not allowed in pseries)
quadrant 3: lpid = LPIDR, pid = 0

If we can't get the fully qualified address we raise a segment interrupt.

2. Find the guest radix tree

We ask the virtual hypervisor for the partition table which was registered
with H_REGISTER_PROC_TBL which points us to the process table in guest
memory. We then index this table by pid to get the process table entry
which points us to the appropriate radix tree to translate the address.

If the process table isn't big enough to contain an entry for the current
pid then we raise a storage interrupt.

3. Walk the radix tree

Next we walk the radix tree where each level is a table of page directory
entries indexed by some number of bits from the effective address, where
the number of bits is determined by the table size. We continue to walk
the tree (while entries are valid and the table is of minimum size) until
we reach a table of page table entries, indicated by having the leaf bit
set. The appropriate pte is then checked for sufficient access permissions,
the reference and change bits are updated and the real address is
calculated from the real page number bits of the pte and the low bits of
the effective address.

If we can't find an entry or can't access the entry bacause of permissions
then we raise a storage interrupt.

Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-2.9-20170303' into staging

ppc patch queuye for 2017-03-03

This will probably be my last pull request before the hard freeze. It
has some new work, but that has all been posted in draft before the
soft freeze, so I think it's reasonable to include in qemu-2.9.

This batch has:
* A substantial amount of POWER9 work
* Implements the legacy (hash) MMU for POWER9
* Some more preliminaries for implementing the POWER9 radix
MMU
* POWER9 has_work
* Basic POWER9 compatibility mode handling
* Removal of some premature tests
* Some cleanups and fixes to the existing MMU code to make the
POWER9 work simpler
* A bugfix for TCG multiply adds on power
* Allow pseries guests to access PCIe extended config space

This also includes a code-motion not strictly in ppc code - moving
getrampagesize() from ppc code to exec.c. This will make some future
VFIO improvements easier, Paolo said it was ok to merge via my tree.

target/ppc/POWER9: Add POWER9 mmu fault handler

Add a new mmu fault handler for the POWER9 cpu and add it as the handler
for the POWER9 cpu definition.

This handler checks if the guest is radix or hash based on the value in the
partition table entry and calls the correct fault handler accordingly.

The hash fault handling code has also been updated to check if the
partition is using segment tables.

Currently only legacy hash (no segment tables) is supported.
