Re: [PATH v2] NVMe: init nvme queue before enabling irq

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 




From: Wenbo Wang <wenbo.wang@xxxxxxxxxxxx>

During reset process, the nvme_dev->bar (ioremapped) may change,
so nvmeq->q_db shall be also updated by nvme_init_queue().

Currently nvmeq irq is enabled before queue init, so a spurious
interrupt triggered nvme_process_cq may access nvmeq->q_db just
before it is updated, this could cause kernel panic.
