10Date: Oct 2019
11Contact: linux-crypto@vger.kernel.org

17What: /sys/kernel/debug/hisi_sec2/<bdf>/alg_qos
18Date: Jun 2021
19Contact: linux-crypto@vger.kernel.org
20Description: The <bdf> is related the function for PF and VF.
21 SEC driver supports to configure each function's QoS, the driver
22 supports to write <bdf> value to alg_qos in the host. Such as
23 "echo <bdf> value > alg_qos". The qos value is 1~1000, means
24 1/1000~1000/1000 of total QoS. The driver reading alg_qos to
25 get related QoS in the host and VM, Such as "cat alg_qos".
