PPC: Add GS MSR definition
The BookE specification defines MSR bit 28 as Guest State. Add itto the list of MSR macros.

PPC: Add another 64 bits to instruction feature mask
To enable quick runtime detection of instruction groups to the currentlyselected CPU emulation, we have a feature mask of what exactly the respectiveinstruction supports.
This feature mask is 64 bits long and we just successfully exceeded those 64...
PPC: Implement e500 (FSL) MMU
Most of the code to support e500 style MMUs is already in place, butwe're missing on some of the special TLB0-TLB1 handling code and slightlydifferent TLB modification.
This patch adds support for the FSL style MMU.
monitor: add PPC BookE SPRs
Read them via KVM_GET_SREGS in kvm_arch_get_registers(),and display them in "info registers".
Also get CR and PID from the existing KVM_GET_REGS.

Implement PAPR VPA functions for pSeries shared processor partitions
Shared-processor partitions are those where a CPU is time-sliced betweenpartitions, rather than being permanently dedicated to a singlepartition. qemu emulated partitions, since they are just scheduled with...
Parse SDR1 on mtspr instead of at translate time
On ppc machines with hash table MMUs, the special purpose register SDR1contains both the base address of the encoded size (hashed) page tables.
At present, we interpret the SDR1 value within the address translation...
Use "hash" more consistently in ppc mmu code
Currently, get_segment() has a variable called hash. However it doesn't(quite) get the hash value for the ppc hashed page table. Instead itgets the hash shifted - effectively the offset of the hash bucket within...
Better factor the ppc hash translation path
Currently the path handling hash page table translation in get_segment()has a mix of common and 32 or 64 bit specific code. However thedivision is not done terribly well which results in a lot of messy codeflipping between common and divided paths....
Support 1T segments on ppc
Traditionally, the "segments" used for the two-stage translation used onpowerpc MMUs were 256MB in size. This was the only option on all hashpage table based 32-bit powerpc cpus, and on the earlier 64-bit hash pagetable based cpus. However, newer 64-bit cpus also permit 1TB segments...
Add POWER7 support for ppc
This adds emulation support for the recent POWER7 cpu to qemu. It's farfrom perfect - it's missing a number of POWER7 features so far, includingany support for VSX or decimal floating point instructions. However, it'sclose enough to boot a kernel with the POWER7 PVR....
Virtual hash page table handling on pSeries machine
On pSeries logical partitions, excepting the old POWER4-style full systempartitions, the guest does not have direct access to the hardware pagetable. Instead, the pagetable exists in hypervisor memory, and the guest...
Clean up PowerPC SLB handling code
Currently the SLB information when emulating a PowerPC 970 isstoreed in a structure with the unhelpfully named fields 'tmp'and 'tmp64'. While the layout in these fields does match thedescription of the SLB in the architecture document, it is not...
Add a hook to allow hypercalls to be emulated on PowerPC
PowerPC and POWER chips since the POWER4 and 970 have a specialhypervisor mode, and a corresponding form of the system callinstruction which traps to the hypervisor.
qemu currently has stub implementations of hypervisor mode. That...
Implement PowerPC slbmfee and slbmfev instructions
For a 64-bit PowerPC target, qemu correctly implements translationthrough the segment lookaside buffer. Likewise it supports theslbmte instruction which is used to load entries into the SLB.
However, it does not emulate the slbmfee and slbmfev instructions...

qemu already includes support for the popcntb instruction introducedin POWER5 (although it doesn't actually allow you to choose POWER5).
However, the logic is slightly incorrect: it will generate results...

PPC: Make DCR uint32_t

On PPC we have a 64-bit time base. Usually (PPC32) this is accessed usingtwo separate 32 bit SPR accesses to SPR_TBU and SPR_TBL.
