PPC: e500: advertise 4.2 MPIC only if KVM supports EPR
Older KVM versions don't support EPR which breaks guests when we announceMPIC variants that support EPR.
Catch that case and expose only MPIC version 2.0 which tells the guest thatwe don't support the EPR capability yet....
Enable kvm emulated watchdog
Enable the KVM emulated watchdog if KVM supports (use thecapability enablement in watchdog handler). Also watchdog exit(KVM_EXIT_WATCHDOG) handling is added.Watchdog state machine is cleared whenever VM state changes to running....

PPC: KVM: Add support for EPR with KVM
This patch links KVM EPR support to the existing TCG support we have now.

cpu: Move cpu_index field to CPUState
Note that target-alpha accesses this field from TCG, now using anegative offset. Therefore the field is placed last in CPUState.
Pass PowerPCCPU to [kvm]ppc_fixup_cpu() to facilitate this change.
Move common parts of mips cpu_state_reset() to mips_cpu_reset()....
PPC: KVM: set has-idle in guest device tree
On e500mc, the platform doesn't provide a way for the CPU to go idle.
To still not uselessly burn CPU time, expose an idle hypercall to the guestif kvm supports it.

target-ppc: Slim conversion of model definitions to QOM subclasses
Since the model list is highly macrofied, keep ppc_def_t for now andsave a pointer to it in PowerPCCPUClass. This results in a flat list ofsubclasses including aliases, to be refined later....
Merge branch 'master' of git://git.qemu.org/qemu into qom-cpu
Adapt header include paths.

kvm: Pass CPUState to kvm_vcpu_ioctl()
Adapt helper functions to pass X86CPU / PowerPCCPU / S390CPU.
exec: move include files to include/exec/
pseries: Add support for new KVM hash table control call
This adds support for then new "reset htab" ioctl which allows qemuto properly cleanup the MMU hash table when the guest is reset. Withthe corresponding kernel support, reset of a guest now works properly....
ppc64: Rudimentary Support for extra page sizes on server CPUs
More recent Power server chips (i.e. based on the 64 bit hash MMU)support more than just the traditional 4k and 16M page sizes. Thiscan get quite complicated, because which page sizes are supported,...
target-ppc: Add hooks for handling tcg and kvm limitations
On target-ppc, our table of CPU types and features encodes the features asfound on the hardware, regardless of whether these features are actuallyusable under TCG or KVM. We already have cases where the information from...

ppc: Fix up usermode only builds
The recent usage of MemoryRegion in kvm_ppc.h breaks builds withCONFIG_USER_ONLY=y. This patch fixes it.

ppc: First cut implementation of -cpu host
For convenience with kvm, x86 allows the user to specify -cpu host on theqemu command line, which means make the guest cpu the same as the hostcpu. This patch implements the same option for ppc targets.
For now, this just read the host PVR (Processor Version Register) and...
pseries: Support SMT systems for KVM Book3S-HV
Alex Graf has already made qemu support KVM for the pseries machinewhen using the Book3S-PR KVM variant (which runs the guest inusermode, emulating supervisor operations). This code allows gets usvery 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 workwith qemu on POWER7 CPUs. PPC970 CPUs also have hypervisorcapability, but they lack the VRMA feature which makes assigning guestmemory easier....
pseries: Use Book3S-HV TCE acceleration capabilities
The pseries machine of qemu implements the TCE mechanism used as avirtual IOMMU for the PAPR defined virtual IO devices. Because thePAPR spec only defines a small DMA address space, the guest VIOdrivers need to update TCE mappings very frequently - the virtual...
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 vectorextensions (or the later VSX version) and/or the Decimal Floating...
PPC: Enable to use PAPR with PR style KVM
When running PR style KVM, we need to tell the kernel that we wantto run in PAPR mode now. This means that we need to pass some moreregister information down and enable papr mode. We also need to alignthe HTAB to htab_size boundary....
PPC: KVM: Remove kvmppc_read_host_property
We just got rid of the last user of kvmppc_read_host_property, so wecan now safely remove it.
PPC: KVM: Add stubs for kvm helper functions
We have a bunch of helper functions that don't have any stubs for them in casewe don't have CONFIG_KVM enabled. That didn't bite us so far, because gcc canoptimize them out pretty well, but we should really provide them....
PPC: bamboo: Move host fdt copy to target
We have some code in generic kvm_ppc.c that is only used by 440. Move tothe 440 specific device code.
PPC: KVM: Add generic function to read host clockfreq
We need to find out the host's clock-frequency when running on KVM, solet's export a respective function.
v1 -> v2:
- enable 64bit values
ppce500_mpc8544ds: Fix compile with --enable-debug and --disable-kvm
When configured with --enable-debug, we compile without optimization.This means that the function mpc8544_copy_soc_cell() in ppce500_mpc8544ds.cis not optimized out, even though it is never called without kvm. That in...
Implement PAPR CRQ hypercalls
This patch implements the infrastructure and hypercalls necessary for thePAPR specified CRQ (Command Request Queue) mechanism. This generalrequest queueing system is used by many of the PAPR virtual IO devices,including the virtual scsi adapter....
KVM: PPC: Add level based interrupt logic
KVM on PowerPC used to have completely broken interrupt logic. Usually,interrupts work by having a PIC that pulls a line up/down, so the CPU knowsthat an interrupt is active. This line stays active until some action is...
PPC: Add PV hypercall transport through fw_cfg
On KVM for PPC we need to tell the guest which instructions to use whendoing a hypercall. The clean way to do this is to go through an ioctlfrom userspace and passing it on to the guest using the device tree....
PPC: tell the guest about the time base frequency
Our guest systems need to know by how much the timebase increases every second,so there usually is a "timebase-frequency" property in the cpu leaf of thedevice tree.
This property is missing in OpenBIOS....

Implement hooks called by generic KVM code.
Also add code that will copy the host's CPU and timebase frequencies to theguest, which is necessary on KVM because the guest can directly access thetimebase.
