Subject: [PATCH 0/8] vhost-scsi: Memory reduction patches
Date: Tue, 8 Oct 2024 20:44:29 -0500 [thread overview]
Message-ID: <9e67ab6c-f23d-469c-ac36-8b540fb62e00@oracle.com> (raw)
In-Reply-To: <20241009013839.88593-1-michael.christie@oracle.com>
Sorry for the bad email threading. Forgot to pass git send-email
--compose so responding on the first email.
The following patches were made over Linus's tree. They reduce the
memory use for vhost-scsi.
For a simple device with 1 queue and 128 cmds we use around 25 MB. These
patches allow us to reduce that to 8.2 MB when supporting up to 8 MB IOs
(the current passthrough max).
For a more complex device with 16 queues we use around 2.5 GB. These
patches allow us to reduce that to 77.1 MB when supporting 8 MB IOs.
