From: Klaus Jensen <k.jensen@samsung.com>
So, things escalated a bit.
I'm removing the old cover letter. I don't think we need it anymore - you all
know the reason I keep posting versions of this implementation ;)
Based-on: <20200922084533.1273962-1-its@irrelevant.dk>
Changes for v2
~~~~~~~~~~~~~~
* "hw/block/nvme: add support for dulbe and block utilization tracking"
- Factor out pstate init/load into separate functions.
- Fixed a stupid off-by-1 bug that would trigger when resetting the
last zone.
- I added a more formalized pstate file format that includes a
header. This is pretty similar to what is done in Dmitry's series,
but with fewer fields. The device parameters for nvme-ns are still
the "authoritative" ones, so if any parameters that influence LBA
size, number of zones, etc. do not match, an error indicating the
discrepancy will be produced. IIRC, Dmitry's version does the
same.
It is set up such that newer versions can load pstate files from
older versions. The file format header is not unlike a standard
nvme datastructure with reserved areas. This means that when
adding new command sets that require persistent state, it is not
needed to bump the version number, unless the header has to change
dramatically. This is demonstrated when the zoned namespace
command set support is added in "hw/block/nvme: add basic
read/write for zoned namespaces".
* "hw/block/nvme: add basic read/write for zoned namespaces"
- The device will now transition all opened zones to Closed on
"normal shutdown". You can force the "transition to Full" behavior
by killing QEMU from the monitor.
* "hw/block/nvme: add the zone append command"
- Slightly reordered the logic so a LBA Out of Range error is
returned before Invalid Field in Command for normal read/write
commands.
* "hw/block/nvme: support zone active excursions"
- Dropped. Optional and non-critical.
* "hw/block/nvme: support reset/finish recommended limits"
- Dropped. Optional and non-critical.
