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. > 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.
