KVM: x86/vPMU: Define kvm_pmu_ops to support vPMU function dispatch

2015-06-23T12:12:14+00:00

This patch defines a new function pointer struct (kvm_pmu_ops) to support vPMU for both Intel and AMD. The functions pointers defined in this new struct will be linked with Intel and AMD functions later. In the meanwhile the struct that maps from event_sel bits to PERF_TYPE_HARDWARE events is renamed and moved from Intel specific code to kvm_host.h as a common struct.

KVM: x86: move MTRR related code to a separate file

2015-06-19T15:16:26+00:00

MTRR code locates in x86.c and mmu.c so that move them to a separate file to make the organization more clearer and it will be the place where we fully implement vMTRR Signed-off-by: Xiao Guangrong Signed-off-by: Paolo Bonzini

KVM: x86: remove now unneeded include directory from Makefile

2015-03-26T21:43:13+00:00

virt/kvm was never really a good include directory for anything else than locally included headers. With the move of iodev.h there is no need anymore to add this directory the compiler's include path, so remove it from the x86 kvm Makefile.

kvm: x86: move assigned-dev.c and iommu.c to arch/x86/

2014-11-23T17:33:36+00:00

Now that ia64 is gone, we can hide deprecated device assignment in x86. Notable changes: - kvm_vm_ioctl_assigned_device() was moved to x86/kvm_arch_vm_ioctl() The easy parts were removed from generic kvm code, remaining - kvm_iommu_(un)map_pages() would require new code to be moved - struct kvm_assigned_dev_kernel depends on struct kvm_irq_ack_notifier Signed-off-by: Radim Krčmář Signed-off-by: Paolo Bonzini

kvm: x86: move ioapic.c and irq_comm.c back to arch/x86/

2014-11-21T17:02:37+00:00

ia64 does not need them anymore. Ack notifiers become x86-specific too. Suggested-by: Gleb Natapov Reviewed-by: Radim Krcmar Signed-off-by: Paolo Bonzini

kvm: Add VFIO device

2013-10-30T18:02:03+00:00

So far we've succeeded at making KVM and VFIO mostly unaware of each other, but areas are cropping up where a connection beyond eventfds and irqfds needs to be made. This patch introduces a KVM-VFIO device that is meant to be a gateway for such interaction. The user creates the device and can add and remove VFIO groups to it via file descriptors. When a group is added, KVM verifies the group is valid and gets a reference to it via the VFIO external user interface. Signed-off-by: Alex Williamson Signed-off-by: Paolo Bonzini

KVM: get rid of $(addprefix ../../../virt/kvm/, ...) in Makefiles

2013-05-19T12:14:00+00:00

As requested by the KVM maintainers, remove the addprefix used to refer to the main KVM code from the arch code, and replace it with a KVM variable that does the same thing.

kvm: Allow build-time configuration of KVM device assignment

2013-04-28T09:58:56+00:00

We hope to at some point deprecate KVM legacy device assignment in favor of VFIO-based assignment. Towards that end, allow legacy device assignment to be deconfigured. Signed-off-by: Alex Williamson Reviewed-by: Alexander Graf Acked-by: Michael S. Tsirkin Signed-off-by: Gleb Natapov

KVM: Extract generic irqchip logic into irqchip.c

2013-04-26T18:27:17+00:00

The current irq_comm.c file contains pieces of code that are generic across different irqchip implementations, as well as code that is fully IOAPIC specific. Split the generic bits out into irqchip.c. Signed-off-by: Alexander Graf Acked-by: Michael S. Tsirkin

KVM: Remove internal timer abstraction

2012-08-01T03:21:06+00:00

kvm_timer_fn(), the sole inhabitant of timer.c, is only used by lapic.c. Move it there to make it easier to hack on it. struct kvm_timer is a thin wrapper around hrtimer, and only adds obfuscation. Move near its two users (with different names) to prepare for simplification. Signed-off-by: Avi Kivity Signed-off-by: Marcelo Tosatti
