Title:
[ADL] ITBM support for Hybrid platforms
Status in HWE Next:
New
Status in linux package in Ubuntu:
Triaged
Bug description:
[Impact]
Need ITBM support for Hybrid platforms. Need to change the scheduling
order from Core, HT, ATOM to Core, ATOM, HT.
When using ITBM on systems that has a mixture of CPUs supporting
Hyper-Threading and others not supporting it (even offlining HT siblings may
cause the issue to be reproducible). Hybrid topologies meet the aforementioned
condition. In such cases, threads will be consolidated on CPUs of high priority
using got HT siblings, while CPUs of medium priority will remain idle.
