+What:		/sys/kernel/debug/hisi_zip/<bdf>/clear_enable
+Date:		Nov 2018
+Contact:	linux-crypto@vger.kernel.org
+Description:	Compression/decompression core debug registers read clear
+		control. 1 means enable register read clear, otherwise 0.
+		Writing to this file has no functional effect, only enable or
+		disable counters clear after reading of these registers.
+		Only available for PF.

+What:		/sys/kernel/debug/hisi_zip/<bdf>/current_qm
+Date:		Nov 2018
+Contact:	linux-crypto@vger.kernel.org
+Description:	One ZIP controller has one PF and multiple VFs, each function
+		has a QM. Select the QM which below qm refers to.

+What:		/sys/kernel/debug/hisi_zip/<bdf>/alg_qos
+Date:		Jun 2021
+Contact:	linux-crypto@vger.kernel.org
+Description:	The <bdf> is related the function for PF and VF.
+		ZIP driver supports to configure each function's QoS, the driver
+		supports to write <bdf> value to alg_qos in the host. Such as
+		"echo <bdf> value > alg_qos". The qos value is 1~1000, means
+		1/1000~1000/1000 of total QoS. The driver reading alg_qos to
+		get related QoS in the host and VM, Such as "cat alg_qos".
