Such as 35 "echo <bdf> value > alg_qos". The qos value is 1~1000, means 36 1/1000~1000/1000 of total QoS. The driver reading alg_qos to 37 get related QoS in the host and VM, Such as "cat alg_qos". 38 39What: /sys/kernel/debug/hisi_zip/<bdf>/qm/regs 40Date: Nov 2018 41Contact: linux-crypto@vger.kernel.org 42Description: Dump of QM related debug registers. 43 Available for PF and VF in host.
