Contact: linux-crypto@vger.kernel.org
Description: Write the HPRE core selection in the cluster into this file,
and then we can read the debug information of the core.
Only available for PF.
What: /sys/kernel/debug/hisi_hpre/<bdf>/rdclr_en
Date: Sep 2019
Contact: linux-crypto@vger.kernel.org
Description: HPRE cores debug registers read clear control. 1 means enable
register read clear, otherwise 0. Writing to this file has no
functional effect, only enable or disable counters clear after
reading of these registers.
Only available for PF.
What: /sys/kernel/debug/hisi_hpre/<bdf>/current_qm
Date: Sep 2019
Contact: linux-crypto@vger.kernel.org
Description: One HPRE controller has one PF and multiple VFs, each function
has a QM. Select the QM which below qm refers to.
Only available for PF.
What: /sys/kernel/debug/hisi_hpre/<bdf>/alg_qos
Date: Jun 2021
Contact: linux-crypto@vger.kernel.org
Description: The <bdf> is related the function for PF and VF.
HPRE 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".
