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](https://doc.rust-lang.org/std/os/unix/io/trait.FromRawFd.html)
  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`.

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`.

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.

Added

- Support for setting vcpu `kvm_immediate_exit` flag
- Support for the vcpu ioctl `KVM_GET_CPUID2`
- Support for the vcpu ioctl `KVM_GET_MP_STATE`
- Support for the vcpu ioctl `KVM_SET_MP_STATE`
- Support for the vcpu ioctl `KVM_GET_VCPU_EVENTS`
- Support for the vcpu ioctl `KVM_SET_VCPU_EVENTS`
- Support for the vcpu ioctl `KVM_GET_DEBUGREGS`
- Support for the vcpu ioctl `KVM_SET_DEBUGREGS`
- Support for the vcpu ioctl `KVM_GET_XSAVE`
- Support for the vcpu ioctl `KVM_SET_XSAVE`
- Support for the vcpu ioctl `KVM_GET_XCRS`
- Support for the vcpu ioctl `KVM_SET_XCRS`
- Support for the vm ioctl `KVM_GET_IRQCHIP`
- Support for the vm ioctl `KVM_SET_IRQCHIP`
- Support for the vm ioctl `KVM_GET_CLOCK`
- Support for the vm ioctl `KVM_SET_CLOCK`
- Support for the vm ioctl `KVM_GET_PIT2`
- Support for the vm ioctl `KVM_SET_PIT2`
- Support for the vcpu ioctl `KVM_GET_ONE_REG`

Changed
- Function offering support for `KVM_SET_MSRS` also returns the number
  of MSR entries successfully written.

[v0.2.0]

- Fix bug in `KvmRunWrapper`. The memory for `kvm_run` struct was
  not unmapped after the `KvmRunWrapper` object got out of scope.
- Return proper value when receiving the EOI KVM exit.
- Add support for KVM_ENABLE_CAP.
- Add support for KVM_SIGNAL_MSI.
- Mark `set_user_memory_region` as unsafe.
