Hi,
This v6 is based on the master branch at the commit 0fc482b73d8e
("Merge tag 'pull-aspeed-20260105' of https://github.com/legoater/qemu
into staging").
Since there's the discussion around fw_cfg_init_io_nodma() [*], v6
doesn't include that cleanups. Therefore, comparing v5, v6 has *very*
minimal changes and most of patches have been reviewed (except patch 15
- I think it needs an additianl review :-) ).
Thanks for your patience and review!
Introduction
============
A brief introduction from Philippe's v4:
The versioned 'pc' and 'q35' machines up to 2.12 been marked
as deprecated three releases ago, and are older than 6 years,
so according to our support policy we can remove them.
This series only includes the 2.6 and 2.7 machines removal,
as it is a big enough number of LoC removed. Rest will
follow.
Change Log
==========
(Main) changes since v5:
* Merge pc & q35 changes for testing DSDT tables into one patch and
simplify the commit message.
* Reorganize S-o-b and collect review tags from Igor.
(Main) changes since v4:
* Completely remove the legacy CPU hotplug approach.
- New patch 2-8.
- Test CPU hot-plug & hot-unplug via qmp.
* Keep "dma_enabled" property in fw_cfg_io_properties[] since Sun4u &
Sun4v are still using it.
- About more details, please see commit message of patch 15.
* Temporarily keep these properties: "cpuid-0xb" (of X86CPU),
"fill-mtrr-mask" (of X86CPU), "version" (of IOAPICCommonState).
- These properties will be deprecated first before removal, in
another series.
* Keep "l3-cache" (of X86CPU) and "page-per-vq" (of VirtIOPCIProxy),
since they are still in use (e.g., libvirt).
