2008-12-31KVM: ia64: Fix kvm_arch_vcpu_ioctl_[gs]et_regs()Jes Sorensen1-30/+10
Fix kvm_arch_vcpu_ioctl_[gs]et_regs() to do something meaningful on ia64. Old versions could never have worked since they required pointers to be set in the ioctl payload which were never being set by the ioctl handler for get_regs. In addition reserve extra space for future extensions. The change of layout of struct kvm_regs doesn't require adding a new CAP since get/set regs never worked on ia64 until now. This version doesn't support copying the KVM kernel stack in/out of the kernel. This should be implemented in a seperate ioctl call if ever needed.

2008-12-31KVM: ia64: Add handler for crashed vmmXiantao Zhang4-12/+44
Since vmm runs in an isolated address space and it is just a copy of host's kvm-intel module, so once vmm crashes, we just crash all guests running on it instead of crashing whole kernel. Signed-off-by: Xiantao Zhang <xiantao.zhang@intel.com> Signed-off-by: Avi Kivity <avi@redhat.com>

2008-10-28KVM: Fix guest shared interrupt with in-kernel irqchipSheng Yang1-3/+5
Every call of kvm_set_irq() should offer an irq_source_id, which is allocated by kvm_request_irq_source_id(). Based on irq_source_id, we identify the irq source and implement logical OR for shared level interrupts. The allocated irq_source_id can be freed by kvm_free_irq_source_id(). Currently, we support at most sizeof(unsigned long) different irq sources.
