This patch assumes ARM Cortex-A9. However, it is known to be working on Cortex-A7 and Cortex-A15. Signed-off-by: Vlastimil Kosar Signed-off-by: Jan Viktorin --- v2: * the -mtune parameter of GCC is configurable now * the -mfpu=neon can be turned off v3: XMM_SIZE is defined in rte_vect.h in a following patch v4: * update release notes for 2.2 * get rid of CONFIG_RTE_BITMAP_OPTIMIZATIONS=0 setting * rename arm defconfig: "armv7-a" -> "arvm7a" * disable pipeline and table modules unless lpm is fixed --- config/defconfig_arm-armv7a-linuxapp-gcc | 76 ++++++++++++++++++++++++++++++++ doc/guides/rel_notes/release_2_2.rst | 5 +++ mk/arch/arm/rte.vars.mk | 39 ++++++++++++++++ mk/machine/armv7-a/rte.vars.mk | 67 ++++++++++++++++++++++++++++ 4 files changed, 187 insertions(+) create mode 100644 config/defconfig_arm-armv7a-linuxapp-gcc create mode 100644 mk/arch/arm/rte.vars.mk create mode 100644 mk/machine/armv7-a/rte.vars.mk diff --git a/config/defconfig_arm-armv7a-linuxapp-gcc b/config/defconfig_arm-armv7a-linuxapp-gcc new file mode 100644 index 0000000..82143af --- /dev/null +++ b/config/defconfig_arm-armv7a-linuxapp-gcc @@ -0,0 +1,76 @@ +# BSD LICENSE +# +# Copyright (C) 2015 RehiveTech.
