2013-12-20target-ppc: move POWER7+ to a separate familyAlexey Kardashevskiy1-0/+38
So far POWER7+ was a part of POWER7 family. However it has a different PVR base value so in order to support PVR masks, it needs a separate family class. This adds a new family class, PVR base and mask values and moves Power7+ v2.1 CPU to a new family. The class init function is copied from the POWER7 family. This defines a firmware name for the new family as "PowerPC,POWER7+" instead of previously used "PowerPC,POWER7" from the POWER7 family. The reason for that is that the Sapphire firmware (a h0st firmware) uses "PowerPC,POWER7+" already and since no specification defines exactly the CPU nodes naming in the device tree, we better stay in sync with the host firmware.

2013-12-20powerpc: add PVR mask supportAlexey Kardashevskiy1-0/+44
IBM POWERPC processors encode PVR as a CPU family in higher 16 bits and a CPU version in lower 16 bits. Since there is no significant change in behavior between versions, there is no point to add every single CPU version in QEMU's CPU list. Also, new CPU versions of already supported CPU won't break the existing code. This adds PVR value/mask support for KVM, i.e. for -cpu host option. As CPU family class name for POWER7 is "POWER7-family", there is no need to touch aliases.

2013-10-25spapr: Use DeviceClass::fw_name for device tree CPU nodeAndreas Färber1-0/+2
Instead of relying on cpu_model, obtain the device tree node label per CPU. Use DeviceClass::fw_name as source. Whenever DeviceClass::fw_name is unknown, default to "PowerPC,UNKNOWN". As a consequence, spapr_fixup_cpu_dt() can operate on each CPU's fw_name, obsoleting sPAPREnvironment::cpu_model, and spapr_create_fdt_skel() can drop its cpu_model argument.

2013-07-29cpu: Partially revert "cpu: Change qemu_init_vcpu() argument to CPUState"Andreas Färber1-0/+2
Commit c643bed99 moved qemu_init_vcpu() calls to common CPUState code. This causes x86 cpu-add to fail with "KVM: setting VAPIC address failed". The reason for the failure is that CPUClass::kvm_fd is not yet initialized in the following call graph: ->x86_cpu_realizefn ->x86_cpu_apic_realize ->qdev_init ->device_set_realized ->device_reset (hotplugged == 1) ->apic_reset_common ->vapic_base_update ->kvm_apic_vapic_base_update This causes attempted KVM vCPU ioctls to fail. By contrast, in the non-hotplug case the APIC is reset much later, when the vCPU is already initialized. As a quick and safe solution, move the qemu_init_vcpu() call back into the targets' realize functions.

2013-04-26pseries: Fixes and enhancements to L1 cache propertiesDavid Gibson1-0/+3
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.

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.

2013-03-22target-ppc: Use QOM method dispatch for MMU fault handlingDavid Gibson1-1/+53
After previous cleanups, the many scattered checks of env->mmu_model in the ppc MMU implementation have, at least for "classic" hash MMUs been reduced (almost) to a single switch at the top of cpu_ppc_handle_mmu_fault(). An explicit switch is still a pretty ugly way of handling this though. Now that Andreas Färber's CPU QOM cleanups for ppc have gone in, it's quite straightforward to instead make the handle_mmu_fault function a QOM method on the CPU object. This patch implements such a scheme, initializing the method pointer at the same time as the mmu_model variable. We need to keep the latter around for now, because of the MMU types (BookE, 4xx, et al) which haven't been converted to the new scheme yet, and also for a few other uses. It would be good to clean those up eventually. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Alexander Graf <agraf@suse.de>
2013-03-22mmu-hash64: Implement Virtual Page Class Key ProtectionDavid Gibson1-0/+49
Version 2.06 of the Power architecture describes an additional page protection mechanism. Each virtual page has a "class" (0-31) recorded in the PTE. The AMR register contains bits which can prohibit reads and/or writes on a class by class basis. Interestingly, the AMR is userspace readable and writable, however user mode writes are masked by the contents of the UAMOR which is privileged. This patch implements this protection mechanism, along with the AMR and UAMOR SPRs. The architecture also specifies a hypervisor-privileged AMOR register which masks user and supervisor writes to the AMR and UAMOR. We leave this out for now, since we don't at present model hypervisor mode correctly in any case.

This patch, therefore, removes all remaining pieces of 620 support, to stop it cluttering up the platforms we actually care about.

2013-03-08target-ppc: Make host CPU a subclass of the host's CPU modelAndreas Färber1-7/+8
This avoids assigning individual class fields and contributors forgetting to add field assignments in KVM-only code. ppc_cpu_class_find_by_pvr() requires the CPU model classes to be registered, so defer host CPU type registration to kvm_arch_init(). Only register the host CPU type if there is a class with matching PVR. This lets us drop error handling from instance_init.
