Hi Kent,
Is it supported only on Power7+ h/w or is it also supported on P7 too ?
I tried on one of the P7R2 LPAR with Fedora 19 ppc64 running and after modeprobe could not see any suffix with -nx for driver in /proc/crypto/ .

 
Here is the output on from my system
[root@ ~]# modprobe nx-crypto
[root@ ~]# lsmod | grep crypto
nx_crypto 39855 0
[root@ ~]# cat /proc/crypto

Please advice ...

Hi Manas, the hardware accelerators are a new feature starting with POWER7+, so POWER7 systems do not have them.

Hello Kent,

 
Do you know if RHEL or SUSE provide support for the POWER7+ and POWER8 imbedded encryption accelerator? If yes, do no know what versions. I have been unable to find this info on the web.
 
Thanks ... Charlie
