RISC-V specific bits are based on initial work done by Greentime Hu [1] but modified to reuse the common implementation to avoid duplication. [1] https://lkml.org/lkml/2020/1/10/233 This series has been tested on qemu with numa enabled for both RISC-V & ARM64. It would be great if somebody can test it on numa capable ARM64 hardware platforms. This patch series doesn't modify the maintainers list for the common code (arch_numa) as I am not sure if somebody from ARM64 community or Greg should take up the maintainership. Ganapatrao was the original author of the arm64 version. I would be happy to update that in the next revision once it is decided. # numactl --hardware available: 2 nodes (0-1) node 0 cpus: 0 1 2 3 node 0 size: 486 MB node 0 free: 470 MB node 1 cpus: 4 5 6 7 node 1 size: 424 MB node 1 free: 408 MB node distances: node 0 1 0: 10 20 1: 20 10 # numactl -show policy: default preferred node: current physcpubind: 0 1 2 3 4 5 6 7 cpubind: 0 1 nodebind: 0 1 membind: 0 1 For RISC-V, the following qemu series is a pre-requisite(already available in upstream) to test the patches in Qemu and 2 socket OmniXtend FPGA. https://patchwork.kernel.org/project/qemu-devel/list/?series=303313 The patches are also available at https://github.com/atishp04/linux/tree/5.10_numa_unified_v3 There may be some minor conflicts with Mike's cleanup series [2] depending on the order in which these two series are being accepted. I can rebase on top his series if required. [2] https://lkml.org/lkml/2020/8/18/754 Changes from v2->v3: 1. Added Acked-by/Reviewed-by tags. 2. Replaced asm/acpi.h with linux/acpi.h 3. Defined arch_acpi_numa_init as static. Changes from v1->v2: 1. Replaced ARM64 specific compile time protection with ACPI specific ones. 2. Dropped common pcibus_to_node changes. Added required changes in RISC-V. 3. Fixed few typos.
