Description AubreyLi intel_group 2023-02-22 09:26:40 UTC 
In order to meet the massive industry wide push, Platform Runtime Mechanism
(PRM) provides means to reduce System Management Mode (SMM) foot print. PRM
introduces the capability of transitioning certain usages that were executed
out of SMM, to a code that executes with the OS/VMM context.
