pseries: Support SMT systems for KVM Book3S-HV

Alex Graf has already made qemu support KVM for the pseries machine
when using the Book3S-PR KVM variant (which runs the guest in
usermode, emulating supervisor operations). This code allows gets us
very close to also working with KVM Book3S-HV (using the hypervisor...

pseries: Allow KVM Book3S-HV on PPC970 CPUS

At present, using the hypervisor aware Book3S-HV KVM will only work
with qemu on POWER7 CPUs. PPC970 CPUs also have hypervisor
capability, but they lack the VRMA feature which makes assigning guest
memory easier....

pseries: Use Book3S-HV TCE acceleration capabilities

The pseries machine of qemu implements the TCE mechanism used as a
virtual IOMMU for the PAPR defined virtual IO devices. Because the
PAPR spec only defines a small DMA address space, the guest VIO
drivers need to update TCE mappings very frequently - the virtual...

Set an invalid-bits mask for each SPE instructions

SPE instructions are defined by pairs. Currently, the invalid-bits mask is set
for the first instruction, but the second one can have a different mask.

example:
GEN_SPE(efdcmpeq, efdcfs, 0x17, 0x0B, 0x00600000, 0x00180000, PPC_SPE_DOUBLE),...

ppc: Generalize the kvmppc_get_clockfreq() function

Currently the kvmppc_get_clockfreq() function reads the host's clock
frequency from /proc/device-tree, which is useful to past to the guest
in KVM setups. However, there are some other host properties
advertised in the device tree which can also be relevant to the...

pseries: Add device tree properties for VMX/VSX and DFP under kvm

Sufficiently recent PAPR specifications define properties "ibm,vmx"
and "ibm,dfp" on the CPU node which advertise whether the VMX vector
extensions (or the later VSX version) and/or the Decimal Floating...

PPC: booke timers

While working on the emulation of the freescale p2010 (e500v2) I realized that
there's no implementation of booke's timers features. Currently mpc8544 uses
ppc_emb (ppc_emb_timers_init) which is close but not exactly like booke (for
example booke uses different SPR)....

KVM: PPC: Use HIOR setting for -M pseries with PR KVM

When running with PR KVM, we need to set HIOR directly. Thankfully there
is now a new interface to set registers individually so we can just use that
and poke HIOR into the guest vcpu's HIOR register....

Implement POWER7's CFAR in TCG

This patch implements support for the CFAR SPR on POWER7 (Come From
Address Register), which snapshots the PC value at the time of a branch or
an rfid. The latest powerpc-next kernel also catches it and can show it in
xmon or in the signal frames....
