2013-03-22mmu-hash*: Add hash pte load/store helpersDavid Gibson1-19/+19
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 Gibson1-51/+19
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>
2013-03-22pseries: Move XICS initialization before cpu initializationDavid Gibson2-37/+32
Currently, the pseries machine initializes the cpus, then the XICS interrupt controller. However, to support the upcoming in-kernel XICS implementation we will need to initialize the irq controller before the vcpus. This patch makes the necesssary rearrangement. This means the xics init code can no longer auto-detect the number of cpus ("interrupt servers" in XICS terminology) and so we must pass that in explicitly from the platform code.

2013-03-22pseries: Remove "busname" property for PCI host bridgeDavid Gibson1-1/+1
Currently the "spapr-pci-host-bridge" device has a "busname" property which can be used to override the default assignment of qbus names for the bus subordinate to the PHB. We use that for the default primary PCI bus, to make libvirt happy, which expects there to be a bus named simply "pci". The default qdev core logic would name the bus "pci.0", and the pseries code would otherwise name it "pci@800000020000000" which is the name it is given in the device tree based on its BUID. The "busname" property is rather clunky though, so this patch simplifies things by just using a special case hack for the default PHB, setting busname to "pci" when index=0.

2013-03-22pseries: Fix breakage in CPU QOM conversionDavid Gibson1-1/+1
Commit 259186a7d2f7184efc96ae99bc5658e6159f53ad "cpu: Move halted and interrupt_request fields to CPUState" broke the pseries machine. That's because it uses CPU() instead of ENV_GET_CPU() to convert from the global first_cpu pointer (still a CPUArchState) to a CPUState. This patch fixes the breakage.
