| |
Changes from V10: Return ioctl to per vcpu instead of per vm
Changes from V9: Use kvm_for_each_vcpu to iterate online vcpu's
Changes from V8: Make KVM_GUEST_PAUSED a per vm ioctl instead of per vcpu
Changes from V7: Define KVM_CAP_GUEST_PAUSED and support check Call mark_page_dirty () after setting PVCLOCK_GUEST_STOPPED
Changes from V6: Use __this_cpu_and when clearing the PVCLOCK_GUEST_STOPPED flag
Changes from V5: Collapse generic check_and_clear_guest_stopped into patch 2 Include check_and_clear_guest_stopped defintion to ia64, s390, and powerpc Change check_and_clear_guest_stopped to use __get_cpu_var instead of taking the cpuid arg. Protect check_and_clear_guest_stopped declaration with CONFIG_KVM_CLOCK check
Changes from V4: Rename KVM_GUEST_PAUSED to KVMCLOCK_GUEST_PAUSED Add description of KVMCLOCK_GUEST_PAUSED ioctl to api.txt
Changes from V3: Include CC's on patch 3 Drop clear flag ioctl and have the watchdog clear the flag when it is reset
Changes from V2: A new kvm functions defined in kvm_para.h, the only change to pvclock is the initial flag definition
Changes from V1: (Thanks Marcelo) Host code has all been moved to arch/x86/kvm/x86.c KVM_PAUSE_GUEST was renamed to KVM_GUEST_PAUSED
