kvm-ioctls-v0.11.0

• [#178] Support for the AMD Security Encrypted Virtualization (SEV) through the following VM ioctls: encrypt_op, encrypt_op_sev, register_enc_memory_region and unregister_enc_memory_region.
• [#184] DeviceFd now derives Debug.

v0.10.0

Changed

• Now depends on kvm-bindings >=0.5.0 which replaced the v4.20 KVM bindings
  with the v5.13 ones.
• Updated VcpuExit::Debug to return architecture specific information for the
  debug event.

kvm-ioctls-v0.9.0

Added

• Support for accessing and controlling the Time Stamp Counter on x86 platforms
  through the get_tsc_khz and set_tsc_khz functions.

Changed

• Updated create_vm on aarch64 to create a VM fd from the KVM fd using the
  host's maximum IPA size.

kvm-ioctls-v0.8.0

v0.8.0

Added

• Support for specifying VM type (an opaque platform and architecture specific
  constant) when creating a VM (KVM_CREATE_VM ioctl) via the
  Kvm::create_vm_with_type function.

Changed

• Now depends on kvm-bindings >=0.4.0 to support use of a newer vmm-sys-utils
  dependency.

v0.6.1

Changed

• Enforced the vmm-sys-util dependency to v0.7.0.

kvm-ioctls-v0.7.0

Added

• Support for the system API that returns the maximum allowed vCPU ID
  (KVM_CAP_MAX_VCPU_ID).
• Support for KVM_MEMORY_ENCRYPT_OP.

Fixed

• [#119]: Disallow invalid
  number of cpuid entries to be passed to get_supported_cpuid and
  get_emulated_cpuid.

Changed

• [#123]: Updated
  create_vcpu to use u64 as the parameter for the number of vCPUs.

kvm-ioctls-v0.6.0

Added

• Support for the vcpu ioctls: KVM_SET_GUEST_DEBUG, KVM_KVMCLOCK_CTRL, and
  KVM_GET_REG_LIST.
• Support for the vm ioctl KVM_GET_DEVICE_ATTR.
• Support for the device ioctl KVM_HAS_DEVICE_ATTR.
• Support for VcpuExit::Debug.
• Support for enabling vcpu capabilities using Vcpu::enable_cap.
• Support for checking Hyper-V (HypervSynic and HypervSynic2), MSI
  (MsiDevid), and IPA Size (ArmVmIPASize) capabilities.
  using kvm.check_extension.
• Support for checking the VM capabilities via Vm::check_extension.
• Create a VM with flexible IPA size using Kvm::create_vm_with_ipa_size.

Removed

• Removed Kvm::new_with_fd_number. The same functionality is offered by the
  Kvm FromRawFd
  trait implementation.

Changed

• The VM ioctl unregister_ioevent now correctly unregisters the events that
  correspond to the data match passed as a parameter.
• The SystemEvent Vcpu Exit now also contains the relevant type and flags.
• Updated get_dirty_log such that it does not assume the page size is 4K,
  but instead reads it using libc::sysconf.

kvm-ioctls-v0.5.0

Added

• Support for the vcpu ioctls KVM_GET/SET_VCPU_EVENTS and KVM_GET_DIRTY_LOG on aarch64.
• Support for the vcpu ioctl KVM_IRQ_LINE.

kvm-ioctls-v0.4.0

Added

• Support for unregistering ioeventfds through KVM_IOEVENTFD.

Changed

• Functions working with event FDs now require
  vmm_sys_util::eventfd::EventFd in their interface instead of
  RawFd.
• Functions working with FAM structs kvm_msr_list and kvm_msrs, were
  changed to work with their respective safe counterparts MsrList and
  respectively Msrs.
• Now exporting kvm_ioctls::Error type definition so that users of this
  crate can create their own wrapping errors without having to know the
  Error type used internally by this crate.
• No longer exporting kvm_ioctls::Result. Users of this crate should
  not have to use kvm_ioctls::Result outside the crate.
• kvm_ioctls::Error now works with errno::Error instead of io::Error.

Removed

• CpuId safe wrapper over FAM struct kvm_cpuid2. The safe wrapper is
  now provided by the kvm_bindings crate starting with v0.2.0.
• KVM_MAX_MSR_ENTRIES and MAX_KVM_CPUID_ENTRIES. Equivalent constants
  are provided by the kvm_bindings crate starting with v0.2.0.
