Subject: [PATCH v7 0/3] target/arm: Implement an IMPDEF pauth algorithm
Date: Mon, 11 Jan 2021 13:57:37 -1000 [thread overview]
Message-ID: <20210111235740.462469-1-richard.henderson@linaro.org> (raw)
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 7 changes:
* Fix rebase error (drjones).
Version 6 changes:
* Rearrange xxhash64 (pmm).
* Add documentation (pmm).
