2013-04-08hw: move headers to include/Paolo Bonzini
Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.

2013-03-22mmu-hash*: Add hash pte load/store helpersDavid Gibson
On real hardware the ppc hash page table is stored in memory; accordingly our mmu emulation code can read a hash page table in guest memory. But, when paravirtualized under PAPR, the real hash page table is in host memory, accessible to the guest only via hypercalls. We model this by also allowing the MMU emulation code to access a specially allocated hash page table outside the guest's memory image. At present these two options are implemented with some ugly conditionals at each access point in the mmu emulation code. In the implementation of the PAPR hypercalls, we assume the external hash table. This patch cleans things up by adding helpers to load and store from the hash table for both 32-bit and 64-bit hash mmus. The 64-bit versions handle both the in-guest-memory and outside guest memory cases. The 32-bit versions only handle the in-guest-memory case since no 32-bit systems can have an external hash table at present.

2013-03-22mmu-hash*: Add header file for definitionsDavid Gibson
Currently cpu.h contains a number of definitions relating to the 64-bit hash MMU. Some are used in the MMU emulation code, but some are only used in the spapr MMU management hcall implementations. This patch moves these definitions (except for a few that are needed more widely) into mmu-hash64.h header, shared between the MMU emulation code and the spapr hcall code. The MMU emulation code is also updated to actually use a number of those definitions in place of hard coded constants. Similarly, we add new analogous definitions to mmu-hash32.h and use those in place of many hard-coded constants in mmu-hash32.c Signed-off-by: David Gibson <david@gibson.dropbear.id.au> [agraf: fix 32-bit hosts] Signed-off-by: Alexander Graf <agraf@suse.de>
2013-03-12cpu: Move halted and interrupt_request fields to CPUStateAndreas Färber
Both fields are used in VMState, thus need to be moved together. Explicitly zero them on reset since they were located before breakpoints. Pass PowerPCCPU to kvmppc_handle_halt(). Signed-off-by: Andreas Färber <afaerber@suse.de>

2013-03-01ppc: move more files to hw/ppcPaolo Bonzini
These sPAPR files do not implement devices, move them over. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
