1What: /sys/kernel/debug/hisi_sec2/<bdf>/clear_enable 2Date: Oct 2019 3Contact: linux-crypto@vger.kernel.org 4Description: Enabling/disabling of clear action after reading 5 the SEC debug registers. 6 0: disable, 1: enable. 7 Only available for PF, and take no other effect on SEC. 8 9What: /sys/kernel/debug/hisi_sec2/<bdf>/current_qm 10Date: Oct 2019 11Contact: linux-crypto@vger.kernel.org 12Description: One SEC controller has one PF and multiple VFs, each function 13 has a QM. This file can be used to select the QM which below 14 qm refers to. 15 Only available for PF. 16 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". 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. VF in guest currently only 32 has one debug register. 33 34What: /sys/kernel/debug/hisi_sec2/<bdf>/qm/current_q 35Date: Oct 2019 36Contact: linux-crypto@vger.kernel.org 37Description: One QM of SEC may contain multiple queues.
