Such as 36 "echo <bdf> value > alg_qos". The qos value is 1~1000, means 37 1/1000~1000/1000 of total QoS. The driver reading alg_qos to 38 get related QoS in the host and VM, Such as "cat alg_qos". 39 40What: /sys/kernel/debug/hisi_hpre/<bdf>/regs 41Date: Sep 2019 42Contact: linux-crypto@vger.kernel.org 43Description: Dump debug registers from the HPRE. 44 Only available for PF. 45 46What: /sys/kernel/debug/hisi_hpre/<bdf>/qm/regs 47Date: Sep 2019 48Contact: linux-crypto@vger.kernel.org 49Description: Dump debug registers from the QM. 50 Available for PF and VF in host.
