From 044f0e27dec6e30bb8875a4a12c5f2594964e93f Mon Sep 17 00:00:00 2001 From: Chen Yu Date: Thu, 6 Apr 2023 13:31:48 -0700 Subject: [PATCH] x86/sched: Add the SD_ASYM_PACKING flag to the die domain of hybrid processors Intel Meteor Lake hybrid processors have cores in two separate dies. The cores in one of the dies have higher maximum frequency. Use the SD_ASYM_ PACKING flag to give higher priority to the die with CPUs of higher maximum frequency.
