This is initial patch set to support numa on arm64 based platforms. Tested these patches on cavium's multinode(2 node topology) simulator. Tried all test-cases present in numactl-2.0.9 package.
In this patchset, defined dt bindings for numa mapping for memory nodes. The cpu to node mapping is derived from the existing cpu-map mapping as defined in topology binding. thanks, Ganapat Ganapatrao Kulkarni (4): arm64: defconfig: increase NR_CPUS range to 2-128 arm/arm64:dt:numa: adding numa node mapping for memory nodes. arm64:thunder: Add initial dts for Cavium Thunder SoC in 2 Node topology. arm64:numa: adding numa support for arm64 platforms.
