Changelog

v0.17.0

Changed

• [#255]: Fixed a
  soundness issue when accessing the kvm_run struct. VcpuFd::run() and
  VcpuFd::set_kvm_immediate_exit() now take &mut self as a consequence.
• [#260]: Updated kvm-bindings to 0.8.0.

v0.16.0

Added

• [#242] x86: add support
  for SMI injection via Vcpu::smi() (KVM_SMI ioctl).
• [#241] Add support for
  userspace MSR handling.
• [#246] Add support for
  userspace NMI injection (KVM_NMI ioctl).
• [#244] add support for
  coalesced MMIO (KVM_CAP_COALESCED_MMIO / KVM_CAP_COALESCED_PIO)

Changed

• [#234] vcpu: export
  reg_size as a public method.
• [#243] derived the Copy
  trait for IoEventAddress and NoDatamatch.

v0.15.0

Added

• [#230] Added
  check_extension_raw method to use raw integer values instead
  of Cap enum.
• [#228] arm64: add
  support for vCPU SVE feature.
• [#219] Add Cap::ArmPtrAuthAddress
  and Cap::ArmPtrAuthGeneric capabilities.

Added

• [#219] Support for KVM_GET_MSR_FEATURE_INDEX_LIST and KVM_GET_MSRS system ioctls.
• [#221] Add Cap::ArmPmuV3.

Changed

• [#223] aarch64: Updated get/set_one_reg to support different registers sizes through byte slices.

v0.13.0

Added

• [#213] Add Kvm::new_with_path()
  and Kvm::open_with_cloexec_at() to allow using kvm device files other than
  /dev/kvm.

Added

• [#187] Support for KVM_SET_IDENTITY_MAP_ADDR
• Derive Debug for all exported structs and enums
• [#189] Expose KVM_SET_ and KVM_HAS_DEVICE_ATTR for vcpu
• [#191] Add KVM_TRANSLATE support and the translate_gva function tha translates guest virtual address to the physical address
• [#190] Enable usage of sync_regs to allow bulk getting and setting of general purpose registers, reducing the number of ioctls needed.
• [#198] Return details about KVM_EXIT_FAIL_ENTRY in vCPU run
• [#199] Add register_irqfd_with_resample so that irqfd + resaplefd can be registered through KVM_IRQFD
• [#202] Add KVM_CAP_GUEST_DEBUG_HVM_DPS/WPS
• [#202] Added check_extension_int which allows checking the capabilities that return numbers instead of booleans

Changed

• Updated vmm-sys-util to 0.11.0
• Updated kvm-bindings to 0.6.0
• Upgraded to rust 2021 edition
• Switched to specifying dependencies using caret requirements instead of comparision requirements
• [#195] Do not panic on unsupported KVM_EXIT reason
• [#196] Expose a mutable reference to the kvm_run structure to allow proper handling of unsupported exit reasons
• [#200] Fix wrong target_arch gate preventing set_guest_debug from being exported on ARM
• [#206] use u128 in get/set_on_reg

Added

• [#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.

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.

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.
