Hi,
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.
This v5 is based on the master branch at the commit 66ec38b6fa59
("Merge tag 'pull-target-arm-20251201' of https://gitlab.com/pm215/qemu
into staging").
(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).
Thank you everyone for the reviews and patience, and also thank you
Philippe for the guidance and Igor for the patch.
Best Regards,
Zhao
