Public bug reported: [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. https://projectacrn.org/ [Fix] Intel provides a list of patches to enable AlderLake [Test] This is requested by Intel. [Where problems could occur] Only applicable on Intel AlderLake. Further testing will be required. ** Affects: hwe-next Importance: Undecided Status: New ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Tags: intel oem-priority originate-from-1943549 ** Tags added: intel oem-priority originate-from-1943549 -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1952007 Title: [ADL] ITBM support for Hybrid platforms Status in HWE Next: New Status in linux package in Ubuntu: New Bug description: [Impact] Need ITBM support for Hybrid platforms.
