[PATCH v6 0/3] target/arm: Implement an IMPDEF pauth algorithm

Posted by Richard Henderson 4 years, 10 months ago

The architected pauth algorithm is quite slow without
hardware support, and boot times for kernels that enable
use of the feature have been significantly impacted.

Version 6 changes:
  * Rearrange xxhash64 (pmm).
  * Add documentation (pmm).
