Subject: [PATCH v7 00/12] Enabling DCD emulation support in Qemu
Date: Thu, 18 Apr 2024 16:10:51 -0700	[thread overview]
Message-ID: <20240418232902.583744-1-fan.ni@samsung.com> (raw)

A git tree of this series can be found here (with one extra commit on top
for printing out accepted/pending extent list): 
https://github.com/moking/qemu/tree/dcd-v7

v6->v7:

1. Fixed the dvsec range register issue mentioned in the the cover letter in v6.
   Only relevant bits are set to mark the device ready (Patch 6). (Jonathan)
2. Moved the if statement in cxl_setup_memory from Patch 6 to Patch 4. (Jonathan)
3. Used MIN instead of if statement to get record_count in Patch 7. (Jonathan)
4. Added "Reviewed-by" tag to Patch 7.
5. Modified cxl_dc_extent_release_dry_run so the updated extent list can be
   reused in cmd_dcd_release_dyn_cap to simplify the process in Patch 8. (Jørgen) 
6. Added comments to indicate further "TODO" items in cmd_dcd_add_dyn_cap_rsp.
    (Jonathan)
7. Avoided irrelevant code reformat in Patch 8. (Jonathan)
8. Modified QMP interfaces for adding/releasing DC extents to allow passing
   tags, selection policy, flags in the interface. (Jonathan, Gregory)
9. Redesigned the pending list so extents in the same requests are grouped
    together. A new data structure is introduced to represent "extent group"
    in pending list.  (Jonathan)
10. Added support in QMP interface for "More" flag. 
11. Check "Forced removal" flag for release request and not let it pass through.
12. Removed the dynamic capacity log type from CxlEventLog definition in cxl.json
   to avoid the side effect it may introduce to inject error to DC event log.
   (Jonathan)
13. Hard coded the event log type to dynamic capacity event log in QMP
    interfaces. (Jonathan)
14. Adding space in between "-1]". (Jonathan)
15. Some minor comment fixes.

The code is tested with similar setup and has passed similar tests as listed
in the cover letter of v5[1] and v6[2].
Also, the code is tested with the latest DCD kernel patchset[3].
