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". 26 27What: /sys/kernel/debug/hisi_sec2/<bdf>/qm/qm_regs 28Date: Oct 2019 29Contact: linux-crypto@vger.kernel.org 30Description: Dump of QM related debug registers. 31 Available for PF and VF in host.
