This can be tested by doing a cross-compile for armv8-a type using the linaro gcc toolchain. meson arm-build --cross-file aarch64_cross.txt ninja -C arm-build where aarch64_cross.txt contained the following [binaries] c = 'aarch64-linux-gnu-gcc' cpp = 'aarch64-linux-gnu-cpp' ar = 'aarch64-linux-gnu-ar' [host_machine] system = 'linux' cpu_family = 'aarch64' cpu = 'armv8-a' endian = 'little' Signed-off-by: Bruce Richardson Signed-off-by: Pavan Nikhilesh Acked-by: Jerin Jacob --- diff --git a/config/arm/meson.build b/config/arm/meson.build new file mode 100644 index 0000000000..f05de4c2c5 --- /dev/null +++ b/config/arm/meson.build @@ -0,0 +1,36 @@ +# SPDX-License-Identifier: BSD-3-Clause +# Copyright(c) 2017 Intel Corporation. +# Copyright(c) 2017 Cavium, Inc + +# for checking defines we need to use the correct compiler flags +march_opt = '-march=@0@'.format(machine) + +dpdk_conf.set('RTE_FORCE_INTRINSICS', 1) +if cc.sizeof('void *') == 8 + dpdk_conf.set('RTE_CACHE_LINE_SIZE', 128) + dpdk_conf.set('RTE_ARCH_ARM64', 1) + dpdk_conf.set('RTE_ARCH_64', 1) +else + dpdk_conf.set('RTE_CACHE_LINE_SIZE', 64) + dpdk_conf.set('RTE_ARCH_ARM', 1) + dpdk_conf.set('RTE_ARCH_ARMv7', 1) +endif + +if cc.get_define('__ARM_NEON', args: march_opt) != '' + dpdk_conf.set('RTE_MACHINE_CPUFLAG_NEON', 1) + compile_time_cpuflags += ['RTE_CPUFLAG_NEON'] +endif + +if cc.get_define('__ARM_FEATURE_CRC32', args: march_opt) != '' + dpdk_conf.set('RTE_MACHINE_CPUFLAG_CRC32', 1) + compile_time_cpuflags += ['RTE_CPUFLAG_CRC32'] +endif + +if cc.get_define('__ARM_FEATURE_CRYPTO', args: march_opt) != '' + dpdk_conf.set('RTE_MACHINE_CPUFLAG_AES', 1) + dpdk_conf.set('RTE_MACHINE_CPUFLAG_PMULL', 1) + dpdk_conf.set('RTE_MACHINE_CPUFLAG_SHA1', 1) + dpdk_conf.set('RTE_MACHINE_CPUFLAG_SHA2', 1) + compile_time_cpuflags += ['RTE_CPUFLAG_AES', 'RTE_CPUFLAG_PMULL', + 'RTE_CPUFLAG_SHA1', 'RTE_CPUFLAG_SHA2'] +endif diff --git a/config/meson.build b/config/meson.build index 95223042f1..fa55c53a5e 100644 --- a/config/meson.build +++ b/config/meson.build @@ -56,8 +56,10 @@ endforeach compile_time_cpuflags = [] if host_machine.cpu_family().startswith('x86') arch_subdir = 'x86' - subdir(arch_subdir) +elif host_machine.cpu_family().startswith('arm') or host_machine.cpu_family().startswith('aarch') + arch_subdir = 'arm' endif +subdir(arch_subdir) dpdk_conf.set('RTE_COMPILE_TIME_CPUFLAGS', ','.join(compile_time_cpuflags)) # set the install path for the drivers diff --git a/lib/librte_eal/common/arch/arm/meson.build b/lib/librte_eal/common/arch/arm/meson.build new file mode 100644 index 0000000000..c6bd92272b --- /dev/null +++ b/lib/librte_eal/common/arch/arm/meson.build @@ -0,0 +1,5 @@ +# SPDX-License-Identifier: BSD-3-Clause +# Copyright(c) 2017 Intel Corporation. + +eal_common_arch_sources = files('rte_cpuflags.c', + 'rte_cycles.c') diff --git a/lib/librte_eal/common/include/arch/arm/meson.build b/lib/librte_eal/common/include/arch/arm/meson.build new file mode 100644 index 0000000000..77893fa359 --- /dev/null +++ b/lib/librte_eal/common/include/arch/arm/meson.build @@ -0,0 +1,29 @@ +# SPDX-License-Identifier: BSD-3-Clause +# Copyright(c) 2017 Intel Corporation. + +install_headers( + 'rte_atomic_32.h', + 'rte_atomic_64.h', + 'rte_atomic.h', + 'rte_byteorder.h', + 'rte_cpuflags_32.h', + 'rte_cpuflags_64.h', + 'rte_cpuflags.h', + 'rte_cycles_32.h', + 'rte_cycles_64.h', + 'rte_cycles.h', + 'rte_io_64.h', + 'rte_io.h', + 'rte_memcpy_32.h', + 'rte_memcpy_64.h', + 'rte_memcpy.h', + 'rte_pause_32.h', + 'rte_pause_64.h', + 'rte_pause.h', + 'rte_prefetch_32.h', + 'rte_prefetch_64.h', + 'rte_prefetch.h', + 'rte_rwlock.h', + 'rte_spinlock.h', + 'rte_vect.h', + subdir: get_option('include_subdir_arch'))
