[Qemu-devel] [PATCH v2 0/4] block: improve luks driver perf & switch to byte APIs

Posted by Daniel P. Berrange 8 years, 2 months ago

This series includes a previously posted patch that improves performance
of the luks crypto driver:

  https://lists.gnu.org/archive/html/qemu-devel/2017-08/msg00781.html

And then adds three patches that switch over to use byte based APIs for
I/O, rather than the legacy sector based APIs.

Daniel P. Berrange (4):
  block: use 1 MB bounce buffers for crypto instead of 16KB
  block: use BDRV_SECTOR_SIZE in crypto driver
  block: convert crypto driver to bdrv_co_preadv|pwritev
  block: convert qcrypto_block_encrypt|decrypt to take bytes offset
