| | | | | | | | | | | | | | | Before hardware V3, hardwares do not provide the feature registers, driver resolves hardware differences based on the hardware version. As a result, the driver does not support the new hardware. Hardware V3 and later versions support to obtain hardware features, such as power-gating management and doorbell isolation, through the hardware registers. To be compatible with later hardware versions, the features of the current device is obtained by reading the hardware registers instead of the hardware version.

* crypto: hisilicon/qm - modify event irq processingWeili Qian2022-06-171-50/+92
| | | | | | | | | | | | | | | | | When the driver receives an event interrupt, the driver will enable the event interrupt after handling all completed tasks on the function, tasks on the function are parsed through only one thread. If the task's user callback takes time, other tasks on the function will be blocked. Therefore, the event irq processing is modified as follows: 1. Obtain the ID of the queue that completes the task. 2. Enable event interrupt. 3. Parse the completed tasks in the queue and call the user callback. Enabling event interrupt in advance can quickly report pending event interrupts and process tasks in multiple threads.
