> Subject: [PATCH v2 00/18] hw/block/nvme: Support Namespace Types and
> Zoned Namespace Command Set
> 
> 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 -
>

> 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.
