The PPC440 User Manual says that if bit 31 is set, the contents of
CR[CR0] are undefined for indexed store instructions but this form is
not invalid. Other PPC variants confirming to recent ISA where this
bit may be reserved should ignore reserved bits and not raise invalid

In a future patch the machine code will need to retrieve the MMU
information from KVM during machine initialization before the CPUs
are created.
Actually, KVM_PPC_GET_SMMU_INFO is a VM class ioctl, and thus, we
don't need to have a CPU object around. We just need for KVM to
be initialized and use the kvm_state global. This patch just does
that.

Now that we're checking our MMU configuration is supported by KVM,
rather than adjusting it to KVM, it doesn't really make sense to
have a fallback for kvm_get_smmu_info(). If KVM is too old or buggy
to provide the details, we should rather treat this as an error.
This patch thus adds error reporting to kvm_get_smmu_info() and get
rid of the fallback code. QEMU will now terminate if KVM fails to
provide MMU details. This may break some very old setups, but the
simplification is worth the sacrifice.

The FPSCR[FI] bit indicates if the last floating point instruction had a result that was rounded. Each consecutive floating point instruction is suppose to set this bit to the correct value. What currently happens is this bit is not set as often as it should be. I have verified that this is the behavior of a real PowerPC 950. This patch fixes that problem by deciding to set this bit after each floating point instruction.

Currently during KVM initialization on POWER, kvm_fixup_page_sizes()
rewrites a bunch of information in the cpu state to reflect the
capabilities of the host MMU and KVM. This overwrites the information
that's already there reflecting how the TCG implementation of the MMU will
operate.
This means that we can get guest-visibly different behaviour between KVM
and TCG (and between different KVM implementations). That's bad. It also
prevents migration between KVM and TCG.
The pseries machine type now has filtering of the pagesizes it allows the
guest to use which means it can present a consistent model of the MMU
across all accelerators.
So, we can now replace kvm_fixup_page_sizes() with kvm_check_mmu() which
merely verifies that the expected cpu model can be faithfully handled by
KVM, rather than updating the cpu model to match KVM.
We call kvm_check_mmu() from the spapr cpu reset code. This is a hack:
conceptually it makes more sense where fixup_page_sizes() was - in the KVM
cpu init path. However, doing that would require moving the platform's
pagesize filtering much earlier, which would require a lot of work making
further adjustments. There wouldn't be a lot of concrete point to doing
that, since the only KVM implementation which has the awkward MMU
restrictions is KVM HV, which can only work with an spapr guest anyway.

The paravirtualized PAPR platform sometimes needs to restrict the guest to
using only some of the page sizes actually supported by the host's MMU.
At the moment this is handled in KVM specific code, but for consistency we
want to apply the same limitations to all accelerators.
This makes a start on this by providing a helper function in the cpu code
to allow platform code to remove some of the cpu's page size definitions
via a caller supplied callback.

The way we used to handle KVM allowable guest pagesizes for PAPR guests
required some convoluted checking of memory attached to the guest.
The allowable pagesizes advertised to the guest cpus depended on the memory
which was attached at boot, but then we needed to ensure that any memory
later hotplugged didn't change which pagesizes were allowed.
Now that we have an explicit machine option to control the allowable
maximum pagesize we can simplify this. We just check all memory backends
against that declared pagesize. We check base and cold-plugged memory at
reset time, and hotplugged memory at pre_plug() time.

Fix the helper_fpscr_clrbit() function so it correctly sets the FEX
and VX bits.
Determining the value for the Floating Point Status and Control
Register's (FPSCR) FEX bit is suppose to be done like this:
FEX = (VX & VE) | (OX & OE) | (UX & UE) | (ZX & ZE) | (XX & XE))
It is described as "the logical OR of all the floating-point exception
bits masked by their respective enable bits". It was not implemented
correctly. The value of FEX would stay on even when all other bits
were set to off.
The VX bit is described as "the logical OR of all of the invalid
operation exceptions". This bit was also not implemented correctly. It
too would stay on when all the other bits were set to off.
My main source of information is an IBM document called:
PowerPC Microprocessor Family:
The Programming Environments for 32-Bit Microprocessors
Page 62 is where the FPSCR information is located.
This is an older copy than the one I use but it is still very useful:

KVM HV has a restriction that for HPT mode guests, guest pages must be hpa
contiguous as well as gpa contiguous. We have to account for that in
various places. We determine whether we're subject to this restriction
from the SMMU information exposed by KVM.
Planned cleanups to the way we handle this will require knowing whether
this restriction is in play in wider parts of the code. So, expose a
helper function which returns it.
This does mean some redundant calls to kvm_get_smmu_info(), but they'll go

ppc_check_compat() is used in a number of places to check if a cpu object

It takes a PowerPCCPU *, however it really only depends on the cpu's class.
We have upcoming cases where it would be useful to make compatibility
checks before we fully instantiate the cpu objects.
ppc_type_check_compat() will now make an equivalent check, but based on a
CPU's QOM typename instead of an instantiated CPU object.
We make use of the new interface in several places in spapr, where we're
essentially making a global check, rather than one specific to a particular

CPUPPCState currently contains a number of fields containing the state of
the VPA. The VPA is a PAPR specific concept covering several guest/host
shared memory areas used to communicate some information with the
hypervisor.
As a PAPR concept this is really machine specific information, although it
is per-cpu, so it doesn't really belong in the core CPU state structure.
There's also other information that's per-cpu, but platform/machine
specific. So create a (void *)machine_data in PowerPCCPU which can be
used by the machine to locate per-cpu data. Intialization, lifetime and
cleanup of machine_data is entirely up to the machine type.

POWER9 introduced a new variant of the eieio instruction using bit 6
as a hint to tell the CPU it is a store-forwarding barrier.
The usage of this eieio extension was recently added in Linux 4.17
which activated the "support for a store forwarding barrier at kernel
entry/exit".
Unfortunately, it is not possible to insert this new eieio instruction
without considerable change in ppc_tr_translate_insn(). So instead we
loosen the QEMU eieio instruction mask and modify the gen_eieio()
helper to test for bit6. On non-POWER9 CPUs, the bit6 is just ignored

With this patch Qemu makes this register available as a hypervisor

Note that bits set in this register disable features of the processor.
Currently the only register state that is supported is when the register
