Subject: [PATCH V5 01/31] smartpqi: use host wide tagspace
Date: Thu, 11 Mar 2021 14:14:57 -0600 [thread overview]
Message-ID: <161549369787.25025.8975999483518581619.stgit@brunhilda> (raw)
In-Reply-To: <161549045434.25025.17473629602756431540.stgit@brunhilda>
Correct scsi-mid-layer sending more requests than
exposed host Q depth causing firmware ASSERT and lockup
issue by enabling host wide tags.
Note: this also results in better performance.
