crypto: hisilicon - support querying the capability register

2024-11-02T10:23:24Z

Query the capability register status of accelerator devices (SEC, HPRE and ZIP) through the debugfs interface, for example: cat cap_regs. The purpose is to improve the robustness and locability of hardware devices and drivers. Signed-off-by: Qi Tao Signed-off-by: Chenghai Huang Signed-off-by: Herbert Xu

crypto: hisilicon/qm - obtain stop queue status

2024-02-17T01:09:16Z

The debugfs files 'dev_state' and 'dev_timeout' are added. Users can query the current queue stop status through these two files. And set the waiting timeout when the queue is released. dev_state: if dev_timeout is set, dev_state indicates the status of stopping the queue. 0 indicates that the queue is stopped successfully. Other values indicate that the queue stops fail. If dev_timeout is not set, the value of dev_state is 0; dev_timeout: if the queue fails to stop, the queue is released after waiting dev_timeout * 20ms.

crypto: hisilicon/qm - support get device state

2024-01-26T08:39:32Z

Support get device current state. The value 0 indicates that the device is busy, and the value 1 indicates that the device is idle. When the device is in suspended, 1 is returned. Signed-off-by: Weili Qian Signed-off-by: Herbert Xu

crypto: hisilicon/qm - simplify the status of qm

2023-12-01T10:03:26Z

The 'QM_INIT' and 'QM_CLOSE' status of qm and 'QP_INIT' and 'QP_CLOSE' status of queue are not actually used. Currently, driver only needs to switch status when the device or queue is enabled or stopped, Therefore, remove unneeded status to simplify driver. In addition, rename'QM_START to'QM_WORK' for ease to understand. Signed-off-by: Weili Qian Signed-off-by: Herbert Xu

crypto: hisilicon/qm - change debugfs file name from qm_regs to regs

2020-05-22T14:08:23Z
