Subject: [PATCH v2 00/18] hw/block/nvme: Support Namespace Types and Zoned Namespace Command Set
Date: Thu, 18 Jun 2020 06:33:57 +0900 [thread overview]
Message-ID: <20200617213415.22417-1-dmitry.fomichev@wdc.com> (raw)
v2: rebased on top of block-next/block branch
Zoned Namespace (ZNS) Command Set is a newly introduced command set
published by the NVM Express, Inc. organization as TP 4053. The main
design goals of ZNS are to provide hardware designers the means to
reduce NVMe controller complexity and to allow achieving a better I/O
latency and throughput. SSDs that implement this interface are
commonly known as ZNS SSDs.
This command set is implementing a zoned storage model, similarly to
ZAC/ZBC. As such, there is already support in Linux, allowing one to
perform the majority of tasks needed for managing ZNS SSDs.
The Zoned Namespace Command Set relies on another TP, known as
Namespace Types (NVMe TP 4056), which introduces support for having
multiple command sets per namespace.
Both ZNS and Namespace Types specifications can be downloaded by
visiting the following link -
https://nvmexpress.org/wp-content/uploads/NVM-Express-1.4-Ratified-TPs.zip
This patch series adds Namespace Types support and zoned namespace
emulation capability to the existing NVMe PCI driver.
The patchset is organized as follows -
The first several patches are preparatory and are added to allow for
an easier review of the subsequent commits. The group of patches that
follows adds NS Types support with only NVM Command Set being
available. Finally, the last group of commits makes definitions and
adds new code to support Zoned Namespace Command Set.
