ACK. Whoever takes this patch might want to fixup 3 typos. On 01/13/2017 07:25 AM, Gonglei wrote:
Some hardware accelerators (like intel aseni or the s390
aesni
cpacf functions) have lower priorities than virtio crypto, and those drivers are faster than the same in the host via virtio. So let's lower the priority of virtio-crypto's algorithm, make it's higher than sofeware
software
implimentations but lower than the hardware ones.
