+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.
