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. 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 cross files. 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. 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. Juraj Linkeš (6): build: alias default build as generic build: refactor Arm build build: optional NUMA and cpu counts detection build: add core and NUMA counts to cross files build: disable Arm drivers build: update Arm builds with makefile flags buildtools/get_cpu_count.py | 7 + buildtools/get_numa_count.py | 22 +++ buildtools/meson.build | 2 + config/arm/arm64_armada_linux_gcc | 6 +- config/arm/arm64_armv8_linux_gcc | 18 +- config/arm/arm64_bluefield_linux_gcc | 7 +- config/arm/arm64_dpaa_linux_gcc | 5 +- config/arm/arm64_emag_linux_gcc | 4 +- config/arm/arm64_n1sdp_linux_gcc | 7 +- config/arm/arm64_octeontx2_linux_gcc | 7 +- config/arm/arm64_stingray_linux_gcc | 7 +- config/arm/arm64_thunderx2_linux_gcc | 6 +- config/arm/arm64_thunderx_linux_gcc | 4 +- config/arm/meson.build | 278 ++++++++++++++++----------- config/meson.build | 54 +++++- drivers/meson.build | 6 +- meson.build | 1 + meson_options.txt | 8 +- 18 files changed, 306 insertions(+), 143 deletions(-) create mode 100644 buildtools/get_cpu_count.py create mode 100644 buildtools/get_numa_count.py -- 2.20.1
