Changes since V1:
Apply Matias' feedback:
- Rebase on top of Matias' latest patches.
- Use nvme_get_log_ext to submit report chunk and export it.
- Re-write report chunk based on Matias' suggestions. Here, I
maintained the lba interface, but it was necessary to redo the
address formatting to match the chunk log page format. For pblk,
this means a double address transformation, but it enables the
standard path to use lbas, plus, this is not in the fast path.
- Fold address format together with address transformations.
- Split the generic geometry patch in different patches.
- Remove refactoring of ligthnvm's core sysfs.
Feedback not applied:
- Not letting pblk know about 1.2 and 2.0 bad block paths. Since the
interfaces for get/set bad block and report chunk are so different,
moving this logic to core adds assumptions on how the targets would
want to get the data back. A way of doing this is creating a logical
report chunk on the 1.2 path, but this would mean that values like
the wear-index are invalid, which requires the target knowledge. I'm
open to suggestions here.
Also:
- Do some further renamings
- Create a generic address format to make it explicit where we share
1.2 and 2.0 fields to avoid address formatting in the fast path.
- Add new fields to sysfs to complete spec and show major/minor
versions (version and subversion to respect current interface).
Implement 2.0 support in pblk. This includes the address formatting and
mapping paths, as well as the sysfs entries for them.
