Hi,

I compiled octeon openssl engine libocteon.so based on
OCTEON-CRYPTO-CORE-1.9.0-60 and OCTEON-ENGINE-LINUX-0.5.0-18.

it works fine under linux-2.6.32.15, but while I upgraded the kernel
to 2.6.33.5 or 2.6.34, running openssl speed test gives me the
following error:

~ # openssl speed -engine octeon rsa1024
Octeon_init success
engine "octeon" set.
Illegal instruction

~ # openssl speed -engine octeon -evp des
Octeon_init success
engine "octeon" set.
Doing des-cbc for 3s on 16 size blocks: Illegal instruction

Here is the compiling output:

make[1]: Entering directory `/root/octcrypto/applications/linux_engine/sample'
make[1]: Leaving directory `/root/octcrypto/applications/linux_engine/sample'

What's happened in the kernel?

thanks very much.

This should be caused by MIPS CU2 exception handler. You can try 
Jesper's patch sumbitted one week ago, see below:

Breaking here dropped us to the default code which always sends
a SIGILL to the current process, no matter what the CU2 notifier says.
