For example, we can't distinguish between N1SDP, Graviton2\nor Ampere Altra.\n\nWe also want to be able to enable/disable which drivers are built\nwithout user input. This is useful when building:\n1. on an SoC that is slow and we want to build only what is necessary\n without the user having to check which libraries they have installed\n2. a cross build on a fast aarch64 machine but with target SoC which\n differs in capabilities or libraries.\nThis is achieved by specifying the drivers in SoC configuration.\n\nThe current implementation adds/supports the following:\n* x86 -> aarch64 cross build with added config options/enabled or\n disabled drivers/libs\n* aarch64 -> aarch64 builds for a different SoCs using meson -Dplatform\n option or using a cross file\n\nv16:\nOnly three commits remaining - updated the cover letter.\nRenamed the 'soc' meson option to 'platform'.\nAdded the support for enabling a particular set of drivers.\nAligned enabling and disabling with the command line option so that\nwildcards can be used.\n\nv17:\nRemoved unnecessary comments in \"build: disable/enable drivers in Arm\nbuilds\". Also always enabled two drivers which break the build if\ndisabled.\n\nJuraj Linkeš (3):\n build: disable/enable drivers in Arm builds\n build: add 'platform' meson option and Arm SoC config\n config: fix Arm implementer and its SoCs\n\n config/arm/arm64_armada_linux_gcc | 6 +-\n config/arm/arm64_armv8_linux_clang_ubuntu1804 | 3 +-\n config/arm/arm64_armv8_linux_gcc | 5 +-\n config/arm/arm64_bluefield_linux_gcc | 6 +-\n config/arm/arm64_dpaa_linux_gcc | 6 +-\n config/arm/arm64_emag_linux_gcc | 5 +-\n config/arm/arm64_graviton2_linux_gcc | 6 +-\n config/arm/arm64_n1sdp_linux_gcc | 6 +-\n config/arm/arm64_n2_linux_gcc | 6 +-\n config/arm/arm64_octeontx2_linux_gcc | 6 +-\n config/arm/arm64_stingray_linux_gcc | 6 +-\n config/arm/arm64_thunderx2_linux_gcc | 5 +-\n config/arm/arm64_thunderxt88_linux_gcc | 5 +-\n config/arm/meson.build | 180 +++++++++++++++---\n .../linux_gsg/cross_build_dpdk_for_arm64.rst | 76 +++-----\n drivers/meson.build | 49 ++++-\n meson.build | 2 +\n meson_options.txt | 4 +\n 18 files changed, 242 insertions(+), 140 deletions(-)" }
