Hi David, Thanks for the reply. I have been using the SafeXcel 1141 card on x86 platform. Need to investigate this further as suggested by you. I have a question, I have noticed that list of hardware accelerators are supported with OCF-Linux is a bit unclear, even though these hardware accelerators are mentioned clearly: 1. Hifn-7751 2. SafeXcel-1141 3. Intel-Ixp. Is this the exhaustive list ? On 7/17/07, David McCullough [off-list ref] wrote:

Hi All, I am trying to integrate OCF-linux with Quicksec on linux 2.6 kernels. Many versions of OCF-Linux have been released but wtihout clear demarcation of 2.6 kernel versions they support. All they mention is support for kernel verison 2.6.11 and later and the README within the distributions states it can be easily modified to support recent version of kernels( which is true, I did it for 2.6.17.7 ) My Question here is that: Is there any good OCF-Linux documentation available ?Only whats on the website. Your best bet is to ask. The current releases work for kernels up to 2.6.18 without any major issues. I should be doing a release this week with everything up to 2.6.22 supported fully. Just finishing off the testing.quoted
What is/are the version of 2.6 kernel, the OCF-Linux is most stable/tested/developed for ? Further I tried to use SafeXcel-1141 hardware accelerator ( which is claimed to be supported) with OCF-Linux, but inserting the module safe.ko (after ocf.ko and cryptodev.ko ) hangs the machine (Kernel version 2.6.17.6 .). Do I need to insmod the SafeXcel-1141 driver too ?I have used the safenet driver on SuperH and ARM platforms. It works fine there. I don't have any way to test it on x86 though. It should work fine on 2.6.17, load everything with debug enabled and see what happens. If you are running on an x86_64 system, disable all the code in "random.c" however, it was broken on 64bits arches in older versions.
