Expand description
Functionality for referencing locked memory buffers for the lifetime of an IO.
Structsยง
- Atomic
IoVec - A pointer/length pair that is ABI compatible with the iovec type on Linux.
- Bounce
Buffer - A page-aligned buffer used to double-buffer IO data.
- Bounce
Buffer Tracker - 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
iovectype on Linux. - Locked
IoBuffers - A set of locked memory ranges, represented by
IoBuffers. - Owned
Request Buffers - A memory range.
- Request
Buffers - An accessor for the memory associated with an IO request.
- Tracked
Bounce Buffer - Tracks an active bounce buffer, signaling to the bounce buffer tracker upon drop that pages can be reclaimed.
