Subject: [PATCH v11 00/10] arm64, numa: Add numa support for arm64 platforms
From: David Daney <david.daney@...ium.com>
v11:
- Dropped cleanup patches for other architectures, they will be
submitted as a separate set after more testing.
- Added patch set from Ard Biesheuvel that are needed to make
the whole thing actually work. Previously this was a
separate set.
- Kconfig and other fixes and simplifications as suggested by Rob Herring.
- Rearranged, refactored and reordered so that we don't patch
new files multiple times.
- Summary:
o 6 patches from Ard Biesheuvel to allow use of
"memory" nodes with efi stub.
o 2 patches to document and add of_numa.c
o 1 patch to add arm64 NUMA support.
o 1 patch to add NUMA balancing support for arm64.
v10:
- Incorporated review comments from Rob Herring.
- Moved numa binding and implementation to devicetree core.
- Added cleanup patch to remove redundant NODE_DATA macro from asm header files
- Include numa balancing support for arm64 patch in this series.
- Fix tile build issue reported by the kbuild robot(patch 7)
v9: - Added cleanup patch to reuse and avoid redefinition of cpumask_of_pcibus
as suggested from Will Deacon and Bjorn Helgaas.
- Including patch to Make pci-host-generic driver numa aware.
- Incorporated comment from Shannon Zhao.
v8:
- Incorporated review comments of Mark Rutland and Will Deacon.
- Added pci helper function and macro for numa.
v7:
- managing numa memory mapping using memblock.
- Incorporated review comments of Mark Rutland.
v6:
- defined and implemented the numa dt binding using
node property proximity and device node distance-map.
- renamed dt_numa to of_numa
v5:
- created base verion of numa.c which creates dummy numa without using dt
on single socket platforms. Then added patches for dt support.
- Incorporated review comments from Hanjun Guo.
v4:
done changes as per Arnd review comments.
v3:
Added changes to support numa on arm64 based platforms.
Tested these patches on cavium's multinode(2 node topology) platform.
In this patchset, defined and implemented dt bindings for numa mapping
for core and memory using device node property arm,associativity.
v2:
Defined and implemented numa map for memory, cores to node and
proximity distance matrix of nodes.
v1:
Initial patchset to support numa on arm64 platforms.
Note: 1. This patchset is tested for NUMA and without NUMA with dt
(both with and without NUMA bindings) on thunderx single
socket and dual socket boards.
Ard Biesheuvel (6):
of/fdt: make generic early_init_dt_add_memory_arch() a weak alias
arm64: override generic version of early_init_dt_add_memory_arch()
efi: move FDT handling to separate object file
arm64/efi: move EFI /chosen node parsing before early FDT processing
arm64/efi: ignore DT memory nodes instead of removing them
arm64/efi: ignore DT memreserve entries instead of removing them
Ganapatrao Kulkarni (4):
Documentation, dt, numa: dt bindings for NUMA.
dt, numa: Add NUMA dt binding implementation.
arm64, numa: Add NUMA support for arm64 platforms.
arm64, mm, numa: Add NUMA balancing support for arm64.
