This is pretty similar to what is done in Dmitry's series,=0D but with fewer fields. The device parameters for nvme-ns are still=0D the "authoritative" ones, so if any parameters that influence LBA=0D size, number of zones, etc. do not match, an error indicating the=0D discrepancy will be produced. IIRC, Dmitry's version does the=0D same.=0D =0D It is set up such that newer versions can load pstate files from=0D older versions. The file format header is not unlike a standard=0D nvme datastructure with reserved areas. This means that when=0D adding new command sets that require persistent state, it is not=0D needed to bump the version number, unless the header has to change=0D dramatically. This is demonstrated when the zoned namespace=0D command set support is added in "hw/block/nvme: add basic=0D read/write for zoned namespaces".=0D =0D * "hw/block/nvme: add basic read/write for zoned namespaces"=0D - The device will now transition all opened zones to Closed on=0D "normal shutdown". You can force the "transition to Full" behavior=0D by killing QEMU from the monitor.=0D =0D * "hw/block/nvme: add the zone append command"=0D - Slightly reordered the logic so a LBA Out of Range error is=0D returned before Invalid Field in Command for normal read/write=0D commands.=0D =0D * "hw/block/nvme: support zone active excursions"=0D - Dropped.
