Only available for PF, and take no other effect on SEC. What: /sys/kernel/debug/hisi_sec2/<bdf>/current_qm Date: Oct 2019 Contact: linux-crypto@vger.kernel.org Description: One SEC controller has one PF and multiple VFs, each function has a QM. This file can be used to select the QM which below qm refers to. Only available for PF. What: /sys/kernel/debug/hisi_sec2/<bdf>/alg_qos Date: Jun 2021 Contact: linux-crypto@vger.kernel.org Description: The <bdf> is related the function for PF and VF. SEC 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".
