Types ¶
type KVM ¶
type KVM struct {
platform.NoCPUPreemptionDetection
// KVM never changes mm_structs.
platform.UseHostProcessMemoryBarrier
// contains filtered or unexported fields
}
KVM represents a lightweight VM context.
func (*KVM) CooperativelySchedulesAddressSpace ¶
CooperativelySchedulesAddressSpace implements platform.Platform.CooperativelySchedulesAddressSpace.
func (*KVM) MaxUserAddress ¶
MaxUserAddress returns the first address that may not be used.
func (*KVM) MinUserAddress ¶
MinUserAddress returns the lowest available address.
func (*KVM) NewAddressSpace ¶
func (k *KVM) NewAddressSpace(any) (platform.AddressSpace, <-chan struct{}, error)
NewAddressSpace returns a new pagetable root.
func (*KVM) NewContext ¶
func (k *KVM) NewContext(pkgcontext.Context) platform.Context
NewContext returns an interruptible context.
func (*KVM) SupportsAddressSpaceIO ¶
SupportsAddressSpaceIO implements platform.Platform.SupportsAddressSpaceIO.
func (*KVM) SyscallFilters ¶
func (k *KVM) SyscallFilters() seccomp.SyscallRules
SyscallFilters returns syscalls made exclusively by the KVM platform.
