KVM: PPC: e500mc support

2012-04-08T09:54:33+00:00

Add processor support for e500mc, using hardware virtualization support (GS-mode). Current issues include: - No support for external proxy (coreint) interrupt mode in the guest. Includes work by Ashish Kalra , Varun Sethi , and Liu Yu . Signed-off-by: Scott Wood Signed-off-by: Alexander Graf Signed-off-by: Avi Kivity

KVM: PPC: Rename MMIO register identifiers

2012-03-05T12:52:41+00:00

We need the KVM_REG namespace for generic register settings now, so let's rename the existing users to something different, enabling us to reuse the namespace for more visible interfaces. While at it, also move these private constants to a private header. Signed-off-by: Alexander Graf Signed-off-by: Avi Kivity

KVM: PPC: Add support for explicit HIOR setting

2012-03-05T12:52:41+00:00

Until now, we always set HIOR based on the PVR, but this is just wrong. Instead, we should be setting HIOR explicitly, so user space can decide what the initial HIOR value is - just like on real hardware. We keep the old PVR based way around for backwards compatibility, but once user space uses the SET_ONE_REG based method, we drop the PVR logic.

KVM: PPC: e500: MMU API

2012-03-05T12:52:24+00:00

This implements a shared-memory API for giving host userspace access to the guest's TLB. Signed-off-by: Scott Wood Signed-off-by: Alexander Graf Signed-off-by: Avi Kivity

KVM: provide synchronous registers in kvm_run

2012-03-05T12:52:22+00:00

On some cpus the overhead for virtualization instructions is in the same range as a system call. Having to call multiple ioctls to get set registers will make certain userspace handled exits more expensive than necessary. Lets provide a section in kvm_run that works as a shared save area for guest registers. We also provide two 64bit flags fields (architecture specific), that will specify 1. which parts of these fields are valid. 2. which registers were modified by userspace Each bit for these flag fields will define a group of registers (like general purpose) or a single register.

KVM: PPC: Whitespace fix for kvm.h

2011-12-27T09:26:43+00:00

kvm.h had sparse whitespace at the end of the line. Clean it up so syncing with QEMU gets easier. Signed-off-by: Alexander Graf

Revert "KVM: PPC: Add support for explicit HIOR setting"

This reverts commit a15bd354f083f20f257db450488db52ac27df439. It exceeded the padding on the SREGS struct, rendering the ABI backwards-incompatible. Conflicts: arch/powerpc/kvm/powerpc.c include/linux/kvm.h Signed-off-by: Avi Kivity

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.
