> Subject: [PATCH v12 00/14] Arm build options rework
>
> The current way of specifying Arm configuration options is insufficient since
> we can't identify the SoC we're building for from the MIDR information. For
> example, we can't distinguish between N1SDP, Graviton2 or Ampere Altra.
>
> Add a way to specify the cpu count and numa node count for cross builds and
> aarch64 -> aarch64 (SoC) builds.
>
> We also want to be able to disable which drivers (and possibly
> libraries) are built without user input. This is useful when building:
> 1. on an SoC that is slow and we want to build only what is necessary
> without the user having to check which libraries they have installed 2. a
> cross build on a fast aarch64 machine but with target SoC which
> differs in capabilities or libraries.
> This is achieved by specifying the drivers in SoC configuration.
>
> Among libraries, only libnuma can be now disabled.
>
> Also add an optional way to discover cpu count a numa node count. Fix -
> Dmax_lcores and -Dmax_numa_nodes for arm builds.
>
> The current implementation adds/supports the following:
> * x86 -> aarch64 cross build with added config options/disabled
> drivers/libs
> * aarch64 -> aarch64 builds for a different SoCs using meson -Darm_soc
> option or using a cross file
> * max numa nodes and max lcore may be specified on the command line to
> overwrite the values for any (native, SoC or cross) build
>
> v2:
> Major rework of the whole series.
>
> v3:
> Added numa and core count defaults for x86 default build.
> Removed numa and core count defaults. Now requiring defaults to be
> specified in a cross file or on the cmdline.
> Added FreeBDS support for numa count discovery.
>
> v4:
> Make automatic numa and cpu counts discovery optional.
>
> v5:
> Split the refactor patch into smaller patches.
> Simplify buildtools/get_numa_count.py.
> Add more explanation to cover letter.
>
> v6:
> Apply cross file options arch agnostically, not just in Arm cross builds.
> Streamline Arm build setup and machine args: always use native args in
> native builds, require implementer ID and part number for cross builds.
>
> v7:
> Arm config options are now organized in one dictionary.
> Removed unsupported implementers and removed fallback to generic
> implementer/part number for unknown implementer/part number.
> Added meson config option arm_soc which can be used to specify
> configuration to be used, useful for aarch64 -> aarch64 builds.
>
> v8:
> Rebase.
>
> v9:
> Split SoC and implementer dictionaries into smaller parts.
> Fixed DPAA and ARMADA SoC configuration.
> Added documentation about supported SoCs.
>
> v10:
> Added a commit that fixes Graviton2 clang build failures in native build.
>
> v11:
> Rebase.
>
> v12:
> Fixed dpaa and armada cross builds in generic build commit.
