Functionality for referencing locked memory buffers for the lifetime of an IO.

Structsยง

  • AtomicIoVec
    A pointer/length pair that is ABI compatible with the iovec type on Linux.
  • BounceBuffer
    A page-aligned buffer used to double-buffer IO data.
  • BounceBufferTracker
    Tracks active bounce buffers against a set limit of pages. If no limit is specified a default of 8Mb will be applied. This limit is tracked per thread specified by the backing AffinitizedThreadpool.
  • IoBuffer
    Wrapper around an &AtomicU8 guaranteed to be ABI compatible with the iovec type on Linux.
  • LockedIoBuffers
    A set of locked memory ranges, represented by IoBuffers.
  • OwnedRequestBuffers
    A memory range.
  • RequestBuffers
    An accessor for the memory associated with an IO request.
  • TrackedBounceBuffer
    Tracks an active bounce buffer, signaling to the bounce buffer tracker upon drop that pages can be reclaimed.
