[PATCH v3 0/3] target/arm: Implement an IMPDEF pauth algorithm

2020-08-15 Thread Richard Henderson
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 1 blurb at https://lists.nongnu.org/archive/html/qemu-devel/2020-08/msg02172.html which contains larger study of the tradeof
