[Ocf-linux-users] ocf-bench generates "Error in OCF processing: 5" using talitos SEC driver

[张绪峰 <sea...@12...>]

Hi experts,

I met some difficulties to run ocf-bench.ko on talitos SEC driver.
It always generate errors "Error in OCF processing: 5" when run "insmod ocf-bench.ko" on 8548e board.

How to reproduce:
1. configure "CONFIG_CRYPTO_DEV_TALITOS=n" "CONFIG_OCF_TALITOS=m"
                    "CONFIG_OCF_OCF=y" "CONFIG_OCF_CRYPTODEV=y" "CONFIG_OCF_BENCH=m"
2. build the kernel and boot the 8548e board.
3. insmod talitos.ko
4. insmod ocf-bench.ko
Then I got such errors "Error in OCF processing: 5".
I know it is due to SEC h/w receive error interrupts during request processing,
and the error bits in Channel_1 CCPSR register is 50 and 55. But I don't know how to do with it.

I also run some openssl speed test such as "openssl speed -evp des -elapsed" on ocf talitos driver,
it seems work fine, no error interrupt happens.

So I want to know why this problem could happen?
Any advice would be appreciated, thanks in advance!



Thanks,
Ted
