Patch 1 adds a sanity check against EAS + SMT. Patch 2 enables CONFIG_SCHED_SMT in the arm64 defconfig. Cheers, Valentin Revisions ========= v1 -> v2 -------- o Collected Reviewed-by, Acked-by (Dietmar, Quentin) o Added a warning when disabling EAS due to SMT (Dietmar) Valentin Schneider (2): sched/topology: Don't enable EAS on SMT systems arm64: defconfig: enable CONFIG_SCHED_SMT arch/arm64/configs/defconfig | 1 + kernel/sched/topology.c | 12 ++++++++++-- 2 files changed, 11 insertions(+), 2 deletions(-) -- 2.24.0
