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.
|
||
|

|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|

|
||
|
|
- The total number of bytes hashed by the hardware using SHA-256.
|
||
|
|
|
||
|
|

|
||
|
|
- The total number of SHA-256 operations submitted to the hardware.
