From ce133a22123055f5f988499cd9ac7953d2bf0677 Mon Sep 17 00:00:00 2001 From: Weili Qian Date: Wed, 7 Feb 2024 17:51:00 +0800 Subject: crypto: hisilicon/qm - obtain stop queue status 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.
