kernel-doc-5.3.2-1.mga7.noarch.rpm

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.
