Longfang Liu 4ee3b3a0ff crypto: hisilicon/qm - prevent soft lockup in receive loop ... [ Upstream commit 33fc506d2a ] In the scenario where the accelerator business is fully loaded. When the workqueue receiving messages and performing callback processing, there are a large number of messages that need to be received, and there are continuously messages that have been processed and need to be received. This will cause the receive loop here to be locked for a long time. This scenario will cause watchdog timeout problems on OS with kernel preemption turned off. The error logs: watchdog: BUG: soft lockup - CPU#23 stuck for 23s! [kworker/u262:1:1407] [ 1461.978428][ C23] Call trace: [ 1461.981890][ C23] complete+0x8c/0xf0 [ 1461.986031][ C23] kcryptd_async_done+0x154/0x1f4 [dm_crypt] [ 1461.992154][ C23] sec_skcipher_callback+0x7c/0xf4 [hisi_sec2] [ 1461.998446][ C23] sec_req_cb+0x104/0x1f4 [hisi_sec2] [ 1462.003950][ C23] qm_poll_req_cb+0xcc/0x150 [hisi_qm] [ 1462.009531][ C23] qm_work_process+0x60/0xc0 [hisi_qm] [ 1462.015101][ C23] process_one_work+0x1c4/0x470 [ 1462.020052][ C23] worker_thread+0x150/0x3c4 [ 1462.024735][ C23] kthread+0x108/0x13c [ 1462.028889][ C23] ret_from_fork+0x10/0x18 Therefore, it is necessary to add an actively scheduled operation in the while loop to prevent this problem. After adding it, no matter whether the OS turns on or off the kernel preemption function. Neither will cause watchdog timeout issues.
