What: /sys/kernel/debug/nx-crypto/*Date : March 2012 KernelVersion : 3 . 4 Contact : Kent Yoder < key @ linux . vnet . ibm . com > Description : These debugfs interfaces are built by the nx - crypto driver , built in arch / powerpc / crypto / nx . Error Detection = = = = = = = = = = = = = = = errors : A u32 providing a total count of errors since the driver was loaded . The only errors counted here are those returned from the hcall , H_COP_OP . last_error : The most recent non - zero return code from the H_COP_OP hcall . - EBUSY is not recorded here ( the hcall will retry until - EBUSY goes away ) . last_error_pid : The process ID of the process who received the most recent error from the hcall . Device Use = = = = = = = = = = aes_bytes : The total number of bytes encrypted using AES in any of the driver ' s supported modes . aes_ops : The total number of AES operations submitted to the hardware . sha256_bytes : The total number of bytes hashed by the hardware using SHA - 256 . sha256_ops : The total number of SHA - 256 operations submitted to the hardware . sha512_bytes : The total number of bytes hashed by the hardware using SHA - 512 . sha512_ops : The total number of SHA - 512 operations submitted to the hardware .
