Subject: RE: [PATCH v8 00/33] x86: enable FRED for x86-64

> Is FRED in any hardware incarnation to rush it?

Current plan is to have FRED HW available in Intel developer Cloud in 1H'2024.

As the cover letter mentioned, for now, it's available through Intel Simics
  https://www.intel.com/content/www/us/en/developer/articles/tool/simics-simulator.html 
, and a developer has to install it on a dev machine.

FRED will also be available publicly through a Simics cloud service in Q2'23,
in which a Simics instance is created for development/QA use.

FRED is a baseline feature, and there are some HW features on top of it. Some of the
new features might be launched with the first FRED HW.

In addition, the KVM FRED patch set is on top of this patch set.

It wasn't my intension to patch-bomb the list. But I will pay attention
regarding this concern.

Thanks!
