5	Description:
6	
7	  These debugfs interfaces are built by the nx-crypto driver, built in
8	arch/powerpc/crypto/nx.

10	Error Detection
11	===============
12	
13	errors:
14	- A u32 providing a total count of errors since the driver was loaded. The
15	only errors counted here are those returned from the hcall, H_COP_OP.
16	
17	last_error:
18	- The most recent non-zero return code from the H_COP_OP hcall. -EBUSY is not
19	recorded here (the hcall will retry until -EBUSY goes away).
20	
21	last_error_pid:
22	- The process ID of the process who received the most recent error from the
23	hcall.
24	
25	Device Use
26	==========
27	
28	aes_bytes:
29	- The total number of bytes encrypted using AES in any of the driver's
30	supported modes.
31	
32	aes_ops:
33	- The total number of AES operations submitted to the hardware.
34	
35	sha256_bytes:
36	- The total number of bytes hashed by the hardware using SHA-256.
37	
38	sha256_ops:
39	- The total number of SHA-256 operations submitted to the hardware.
40	
41	sha512_bytes:
42	- The total number of bytes hashed by the hardware using SHA-512.
43	
44	sha512_ops:
45	- The total number of SHA-512 operations submitted to the hardware.
