[PATCH v3 qemu 0/3] Allow dump-guest-memory to output standard kdump format
Posted by Stephen Brennan 7 months, 2 weeks ago
Hello all,

This is the third version of the kdump patch series, the first and
second revisions being visible at [1] and [2] respectively. You can see
the history and motivation for the patch series described in the cover
letter of [2].

Thank you for your continued feedback and review.
Stephen

Changes from v2 to v3:
- Rather than use "reassembled" flag in QMP API, represent each kdump
  format "kdump-X" with a new enumerator "kdump-raw-X". (The HMP
  interface retains the -R option)
- Return an error if the file descriptor passed in is not seekable, yet
  the requested dump format is kdump-raw-*

Changes from v1 to v2:
- Keep the default as the flattened format
- Add QMP / HMP arguments for "reassembled"

[2]: https://lore.kernel.org/qemu-devel/20230914010315.945705-1-stephen.s.brennan@oracle.com/

Stephen Brennan (3):
  dump: Pass DumpState to write_ functions
  dump: Allow directly outputting raw kdump format
  dump: Add command interface for kdump-raw formats

Hello,

Will this be queued for version 8.2? I see here[1] that the feature
freeze is November 7. I'm not really familiar with QEMU development so I
didn't know if there was a "linux-next" equivalent I could check.

Thanks,
Stephen
