From 8bf7b3b6676270c0ed3e4968608e1e052ecc8606 Mon Sep 17 00:00:00 2001 From: Song Shuai Date: Fri, 10 Mar 2023 19:03:36 +0800 Subject: [PATCH] riscv: Kconfig: enable SCHED_MC kconfig RISC-V now builds the sched domain based on the simple possible map. Enable SCHED_MC to make the building based on cpu_coregroup_mask() which also takes care of the NUMA and cores with LLC.
