[Qemu-devel] [PATCH 0/6] crypto: improve performance of XTS cipher mode

[Daniel P . Berrangé]

The XTS cipher mode is significantly slower than CBC mode. This series
approximately doubles the XTS performance which will improve the I/O
rate for LUKS disks.

Daniel P. Berrangé (6):
  crypto: expand algorithm coverage for cipher benchmark
  crypto: remove code duplication in tweak encrypt/decrypt
  crypto: introduce a xts_uint128 data type
  crypto: convert xts_tweak_encdec to use xts_uint128 type
  crypto: convert xts_mult_x to use xts_uint128 type
  crypto: annotate xts_tweak_encdec as inlineable
