2013-05-06pseries: Factor out check for out-of-bounds LIOBNDavid Gibson1-6/+6
PAPR defines LIOBNs (Logical IO Bus Numbers) to be 32-bit, and we check for values that aren't in the code for H_PUT_TCE. This patch factors the check into spapr_tce_find_by_liobn(), which already checks if a 32-bit LIOBN actually exists. This will become more important as future patches add other hypercalls which need to look up a LIOBN. At the same time we fix the typo in the message.

2013-04-26pseries: Generate device paths for VIO devicesDavid Gibson1-14/+23
This patch implements a get_dev_path qdev hook for the pseries paravirtual VIO bus. With upcoming savevm support, this will become very important for scsi disks hanging of VIO virtual SCSI adapters. scsibus_get_dev_path uses the get_dev_path of the parent adapter if available, but otherwise just uses a local channel/target/lun number to identify the device. So if two disks are present in the system having the same target and lun on seperate VIO scsi adapters, savevm cannot distinguish them. Since the conventional way of using VSCSI adapters is to have just one disk per adapter, such a conflict is very likely.

2013-04-26pseries: Convert VIO code to QOM style type safe(ish) castsDavid Gibson1-2/+2
Curerntly the pseries VIO device code contains quite a few explicit uses of DO_UPCAST and plain C casts. This is (obviously) type unsafe, and not the conventional way of doing things in the QOM model. This patch converts the code to use the QOM convention of per-type macros to do verified casts with OBJECT_CHECK().

2013-04-26pseries: Fix some small errors in XICS logicDavid Gibson1-0/+2

2013-04-26pseries: Fixes and enhancements to L1 cache propertiesDavid Gibson1-2/+19
PAPR requires that the device tree's CPU nodes have several properties with information about the L1 cache. We already create two of these properties, but with incorrect names - "[id]cache-block-size" instead of "[id]-cache-block-size" (note the extra hyphen). We were also missing some of the required cache properties. This patch adds the [id]-cache-line-size properties (which have the same values as the block size properties in all current cases). We also add the [id]-cache-size properties. Adding the cache sizes requires some extra infrastructure in the general target-ppc code to (optionally) set the cache sizes for various CPUs. The CPU family descriptions in translate_init.c can set these sizes - this patch adds correct information for POWER7, I'm leaving other CPU types to people who have a physical example to verify against. In addition, for -cpu host we take the values advertised by the host (if available) and use those to override the information based on PVR.

2013-04-26PPC: mac newworld: fix cpu NIP reset valueAlexander Graf1-0/+2
On -M mac99, we can run 970 CPUs. However, these CPUs define the initial instruction pointer they start execution at as part of their bootup protocol, so effectively it's up to the board to decide where they start. This went unnoticed, because they used to boot at the same location our flash was mapped to, but due to the recent reset changes our 970 CPUs want to reset to 0x100 now, which is always a 0 instruction. Set the initial IP to something reasonable for -M mac99. Signed-off-by: Alexander Graf <agraf@suse.de> Reviewed-by: Fabien Chouteau <chouteau@adacore.com>

2013-04-26PPC: Remove env->hreset_excp_prefixFabien Chouteau1-2/+4
This value is not needed if we use correctly the MSR[IP] bit. excp_prefix is always 0x00000000, except when the MSR[IP] bit is implemented and set to 1, in that case excp_prefix is 0xfff00000. The handling of MSR[IP] was already implemented but not used at reset because the value of env->msr was changed "manually". The patch uses the function hreg_store_msr() to set env->msr, this ensures a good handling of MSR[IP] at reset, and therefore a good value for excp_prefix.

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.

Commit 259186a7d2f7184efc96ae99bc5658e6159f53ad "cpu: Move halted and interrupt_request fields to CPUState" broke the pseries machine.
