Hello,
We want the hardware acceleration feature enabled on our machines
installed with Redhat with westmere series of processors. Now, this feature
comes from pure Linux Kernel 2.6.33 released by Linus Torvalds as provided
by the link below :
http://kernelnewbies.org/Linux_2_6_33#head-12719ade57a6c0dd4ea893cfb21e074512419ca7
In the above link, we have a new feature pertaining to cryptography is
mentioned as pasted below:
ghash: Add PCLMULQDQ accelerated implementation
(commit)
Now, the code "PCLMULQDQ" corrosponds to the new instruction set
introduced by Intel Xeon (westmere).
Redhat's kernel versions are a little different from the pure kernel.
Redhat claims that the current 5.5 release kernel consists of most of the
features of 2.6.34 kernel. However, the information which features are
actually backported and which are not is not present in Redhat website. Thus
I would like to know whether this feature is backported from pure Linux
Kernel to RHEL 5.5 or not.
Additionally I need another information, whether AES-NI alogrithm is
supported in RHEL 5.5.
Thanks in advance.
Regards,
Ghanashyam Hegde
