vm-memory-v0.16.0

Changelog

Upcoming version

[v0.16.0]

Added

• [#287] Support for RISC-V 64-bit platform.
• [#299] atomic_bitmap: support enlarging the bitmap.

Changed

• [#278 Remove GuestMemoryIterator trait, and instead have GuestMemory::iter() return impl Iterator.

vm-memory-v0.15.0

Changelog

[v0.15.0]

Added

• [#270] atomic_bitmap: add capability to reset bits range
• [#285] Annotated modules in lib.rs to indicate their feature
  dependencies such that it is reflected in the docs, enhancing documentation clarity for users.

Changed

• [#275] Fail builds on non 64-bit platforms.

Fixed

• [#279] Remove restriction from read_volatile_from and write_volatile_into
  that made it copy data it chunks of 4096.

vm-memory-v0.14.1

Changelog

[v0.14.1]

Fixed

• [#279] Remove restriction from read_volatile_from and write_volatile_into that made it copy data it chunks of 4096.

vm-memory-v0.14.0

Changelog

[v0.14.0]

Added

• [#266] Derive Debug for several types that were missing it.

Changed

• [#274] Drop Default as requirement for ByteValued.

vm-memory-v0.13.1

Changelog

[v0.13.1]

Added

• [#256] Implement WriteVolatile for std::io::Stdout.
• [#256] Implement WriteVolatile for std::vec::Vec.
• [#256] Implement WriteVolatile for Cursor<&mut [u8]>.
• [#256] Implement ReadVolatile for Cursor<T: AsRef[u8]>.

vm-memory-v0.13.0

Changelog

[v0.13.0]

Added

• [#247] Add ReadVolatile and
  WriteVolatile traits which are equivalents of Read/Write with volatile
  access semantics.

Changed

• [#247] Deprecate
  Bytes::{read_from, read_exact_from, write_to, write_all_to}. Instead use
  ReadVolatile/WriteVolatile, which do not incur the performance penalty
  of copying to hypervisor memory due to Read/Write being incompatible
  with volatile semantics (see also #217).

vm-memory-v0.12.2

Changelog

[v0.12.2]

Fixed

• [#251]: Inserted checks that verify that the value returned by VolatileMemory::get_slice is of
  the correct length.

Deprecated

• [#244] Deprecate volatile memory's as_ptr() interfaces. The new interfaces to be used instead are:
  ptr_guard() and ptr_guard_mut().

vm-memory-v0.12.1

Changelog

[v0.12.1]

Fixed

• [#241] mmap_xen: Don't drop
  the FileOffset while in use #245

vm-memory-v0.12.0

Changelog

[v0.12.0]

Added

• [#241] Add Xen memory
  mapping support: Foreign and Grant. Add new API for accessing pointers to
  volatile slices, as as_ptr() can't be used with Xen's Grant mapping.
• [#237] Implement ByteValued for i/u128.

vm-memory-v0.11.0

Changelog

Added

• [#216] Add GuestRegionMmap::from_region.

Fixed

• [#217] Fix vm-memory internally taking rust-style slices to guest memory in ways that could potentially cause undefined behavior. Removes/deprecates various as_slice/as_slice_mut methods whose usage violated rust's aliasing rules, as well as an unsound impl<'a> VolatileMemory for &'a mut [u8].
