Date: March 2012 |

KernelVersion: 3.4 |

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.
