Subject: [PATCH 0/4] nvmet: support polling queue task for bio request
Date: Wed, 13 Sep 2023 16:36:40 +0800 [thread overview]
Message-ID: <cover.1694592708.git.jacky_gam_2001@163.com> (raw)
Since nvme target currently does not support to submit bio to a polling
queue, the bio's completion relies on system interrupt. But when there
is high workload in system and the competition is very high, so it makes
sense to add polling queue task to submit bio to disk's polling queue
and poll the completion queue of disk.
Ping Gan (4):
nvmet: Add nvme target polling queue task parameters
nvmet: Add polling queue task for nvme target
nvmet: support bio polling queue request
nvme-core: Get lowlevel disk for target polling queue task
