KVM: PPC: Remove 440 support

2014-07-28T13:23:15+00:00

The 440 target hasn't been properly functioning for a few releases and before I was the only one who fixes a very serious bug that indicates to me that nobody used it before either. Furthermore KVM on 440 is slow to the extent of unusable. We don't have to carry along completely unused code. Remove 440 and give us one less thing to worry about. Signed-off-by: Alexander Graf

KVM: PPC: Add devname:kvm aliases for modules

2014-01-09T09:14:00+00:00

Systems that support automatic loading of kernel modules through device aliases should try and automatically load kvm when /dev/kvm gets opened. Add code to support that magic for all PPC kvm targets, even the ones that don't support modules yet. Signed-off-by: Alexander Graf

kvm: powerpc: book3s: Allow the HV and PR selection per virtual machine

2013-10-17T16:42:36+00:00

This moves the kvmppc_ops callbacks to be a per VM entity. This enables us to select HV and PR mode when creating a VM. We also allow both kvm-hv and kvm-pr kernel module to be loaded. To achieve this we move /dev/kvm ownership to kvm.ko module. Depending on which KVM mode we select during VM creation we take a reference count on respective module Signed-off-by: Aneesh Kumar K.V [agraf: fix coding style] Signed-off-by: Alexander Graf

kvm: powerpc: Add kvmppc_ops callback

2013-10-17T13:24:26+00:00

This patch add a new callback kvmppc_ops. This will help us in enabling both HV and PR KVM together in the same kernel. The actual change to enable them together is done in the later patch in the series. Signed-off-by: Aneesh Kumar K.V [agraf: squash in booke changes] Signed-off-by: Alexander Graf

KVM: PPC: Book3E: Refactor ONE_REG ioctl implementation

2013-04-26T18:27:05+00:00

Refactor Book3E ONE_REG ioctl implementation to use kvmppc_get_one_reg/ kvmppc_set_one_reg delegation interface introduced by Book3S. This is necessary for MMU SPRs which are platform specifics. Get rid of useless case braces in the process. Signed-off-by: Mihai Caraman Signed-off-by: Alexander Graf

KVM: PPC: 44x: Initialize PVR

2012-10-05T21:38:47+00:00

We need to make sure that vcpu->arch.pvr is initialized to a sane value, so let's just take the host PVR. Signed-off-by: Alexander Graf

KVM: PPC: booke: Move vm core init/destroy out of booke.c

2012-04-08T09:51:05+00:00

e500mc will want to do lpid allocation/deallocation here. Signed-off-by: Scott Wood Signed-off-by: Alexander Graf Signed-off-by: Avi Kivity

KVM: PPC: booke: add booke-level vcpu load/put

2012-04-08T09:51:04+00:00

This gives us a place to put load/put actions that correspond to code that is booke-specific but not specific to a particular core. Signed-off-by: Scott Wood Signed-off-by: Alexander Graf Signed-off-by: Avi Kivity

powerpc: include export.h for files using EXPORT_SYMBOL/THIS_MODULE

2011-10-31T23:30:38+00:00

Fix failures in powerpc associated with the previously allowed implicit module.h presence that now lead to things like this: arch/powerpc/mm/mmu_context_hash32.c:76:1: error: type defaults to 'int' in declaration of 'EXPORT_SYMBOL_GPL' arch/powerpc/mm/tlb_hash32.c:48:1: error: type defaults to 'int' in declaration of 'EXPORT_SYMBOL' arch/powerpc/kernel/pci_32.c:51:1: error: type defaults to 'int' in declaration of 'EXPORT_SYMBOL_GPL' arch/powerpc/kernel/iomap.c:36:1: error: type defaults to 'int' in declaration of 'EXPORT_SYMBOL' arch/powerpc/platforms/44x/canyonlands.c:126:1: error: type defaults to 'int' in declaration of 'EXPORT_SYMBOL' arch/powerpc/kvm/44x.c:168:59: error: 'THIS_MODULE' undeclared (first use in this function) [with several contibutions from Stephen Rothwell ] Signed-off-by: Paul Gortmaker

KVM: PPC: Add sanity checking to vcpu_run

2011-09-25T16:52:27+00:00

There are multiple features in PowerPC KVM that can now be enabled depending on the user's wishes. Some of the combinations don't make sense or don't work though. So this patch adds a way to check if the executing environment would actually be able to run the guest properly. It also adds sanity checks if PVR is set (should always be true given the current code flow), if PAPR is only used with book3s_64 where it works and that HV KVM is only used in PAPR mode.
