KVM: Introduce __KVM_HAVE_IRQ_LINE

2012-06-18T13:06:35+00:00

This is a preparatory patch for the KVM/ARM implementation. KVM/ARM will use the KVM_IRQ_LINE ioctl, which is currently conditional on __KVM_HAVE_IOAPIC, but ARM obviously doesn't have any IOAPIC support and we need a separate define. Signed-off-by: Christoffer Dall 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: ia64: expose registers in struct kvm_regs

2009-03-24T09:03:03+00:00

Provide register layout for struct kvm_regs exposed to userland. Signed-off-by: Jes Sorensen Signed-off-by: Avi Kivity

KVM: ia64: stack get/restore patch

2009-03-24T09:02:50+00:00

Implement KVM_IA64_VCPU_[GS]ET_STACK ioctl calls. This is required for live migrations. Patch is based on previous implementation that was part of old GET/SET_REGS ioctl calls. Signed-off-by: Jes Sorensen Signed-off-by: Avi Kivity

KVM: New guest debug interface

2009-03-24T09:02:49+00:00

This rips out the support for KVM_DEBUG_GUEST and introduces a new IOCTL instead: KVM_SET_GUEST_DEBUG. The IOCTL payload consists of a generic part, controlling the "main switch" and the single-step feature. The arch specific part adds an x86 interface for intercepting both types of debug exceptions separately and re-injecting them when the host was not interested. Moveover, the foundation for guest debugging via debug registers is layed. To signal breakpoint events properly back to userland, an arch-specific data block is now returned along KVM_EXIT_DEBUG. For x86, the arch block contains the PC, the debug exception, and relevant debug registers to tell debug events properly apart. The availability of this new interface is signaled by KVM_CAP_SET_GUEST_DEBUG. Empty stubs for not yet supported archs are provided. Note that both SVM and VTX are supported, but only the latter was tested yet. Based on the experience with all those VTX corner case, I would be fairly surprised if SVM will work out of the box.

KVM: Avoid using CONFIG_ in userspace visible headers

2009-02-15T00:47:35+00:00

Kconfig symbols are not available in userspace, and are not stripped by headers-install. Avoid their use by adding #defines in to suit each architecture. Signed-off-by: Avi Kivity
