From 00b072c011c540b269d2d7f6fbc17c3b33b445d0 Mon Sep 17 00:00:00 2001 From: Barry Song Date: Tue, 2 Mar 2021 21:41:59 +1300 Subject: Documentation/admin-guide: kernel-parameters: correct the architectures for numa_balancing X86 isn't the only architecture supporting NUMA_BALANCING. ARM64, PPC, S390 and RISCV also support it: arch$ git grep NUMA_BALANCING arm64/Kconfig: select ARCH_SUPPORTS_NUMA_BALANCING arm64/configs/defconfig:CONFIG_NUMA_BALANCING=y arm64/include/asm/pgtable.h:#ifdef CONFIG_NUMA_BALANCING powerpc/configs/powernv_defconfig:CONFIG_NUMA_BALANCING=y powerpc/configs/ppc64_defconfig:CONFIG_NUMA_BALANCING=y powerpc/configs/pseries_defconfig:CONFIG_NUMA_BALANCING=y powerpc/include/asm/book3s/64/pgtable.h:#ifdef CONFIG_NUMA_BALANCING powerpc/include/asm/book3s/64/pgtable.h:#ifdef CONFIG_NUMA_BALANCING powerpc/include/asm/book3s/64/pgtable.h:#endif /* CONFIG_NUMA_BALANCING */ powerpc/include/asm/book3s/64/pgtable.h:#ifdef CONFIG_NUMA_BALANCING powerpc/include/asm/book3s/64/pgtable.h:#endif /* CONFIG_NUMA_BALANCING */ powerpc/include/asm/nohash/pgtable.h:#ifdef CONFIG_NUMA_BALANCING powerpc/include/asm/nohash/pgtable.h:#endif /* CONFIG_NUMA_BALANCING */ powerpc/platforms/Kconfig.cputype: select ARCH_SUPPORTS_NUMA_BALANCING riscv/Kconfig: select ARCH_SUPPORTS_NUMA_BALANCING riscv/include/asm/pgtable.h:#ifdef CONFIG_NUMA_BALANCING s390/Kconfig: select ARCH_SUPPORTS_NUMA_BALANCING s390/configs/debug_defconfig:CONFIG_NUMA_BALANCING=y s390/configs/defconfig:CONFIG_NUMA_BALANCING=y s390/include/asm/pgtable.h:#ifdef CONFIG_NUMA_BALANCING x86/Kconfig: select ARCH_SUPPORTS_NUMA_BALANCING if X86_64 x86/include/asm/pgtable.h:#ifdef CONFIG_NUMA_BALANCING x86/include/asm/pgtable.h:#endif /* CONFIG_NUMA_BALANCING */ On the other hand, setup_numabalancing() is implemented in mm/mempolicy.c which doesn't depend on architectures.
