Has anyone tested the performance impact of using the AMD CCP with OpenVPN for example?
I'm running OpenWrt with Linux 4.14.34 and have build it with kmod-crypto-hw-ccp, which seems to load fine:
[ 8.295226] ccp 0000:00:08.0: 5 command queues available [ 8.301901] ccp 0000:00:08.0: ccp enabled [ 8.306078] ccp 0000:00:08.0: enabled
I don't use OpenVPN, but as people often report that it's quite slow compared to IPSec, I wonder if it can be sped up with the help of the CCP.
There's a wiki page for OpenWrt with instructions for enabling /dev/crypto and making OpenSSL use it:
