Excursion behavior may depend on the internal controller architecture and therefore be vendor-specific. - Dropped support for Zone Attributes and zoned AENs for now. These features can be added in a future series. - NS Types support is extended to handle active/inactive namespaces. - Update the write pointer after backing storage I/O completion, not before. This makes the emulation to run correctly in case of backing device failures. - Avoid division in the I/O path if the device zone size is a power of two (the most common case). Zone index then can be calculated by using bit shift. - A few reported bugs have been fixed. - Indentation in function definitions has been changed to make it the same as the rest of the code. 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 device. 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.
