[Reminder] Feature Freeze is Fri Aug 29, 2025

[Oleksii Kurochko <oleksii.kurochko@xxxxxxxxx>]

Hello community,

I’d like to remind everyone that the Feature Freeze deadline is approaching,
and we still have some outstanding requests from the community for patch series
to be merged into 4.21:

1. Enable guest suspend/resume support on ARM via vPSCI [1]
2. Introduce SCI SCMI SMC multi-agent support [2]
3. Introduce eSPI support [3]
4. FRED work: [4], [5], possibly others (?)
5. Introduce CONFIG_DOMCTL [6]
6. xen/x86: move domctl.o out of PV_SHIM_EXCLUSIVE [7]
7. Some other patch series I missed.

It looks like some of these patch series still require additional work,
and I’m not sure there is enough time left before the end of this week.

Could I kindly ask for an estimation of whether these tasks can be completed in time?
