2016-05-19Add support for multiple microarchitectures in single binaryDamjan Marion2-4/+9
* compiler -march= parameter is changed from native to corei7 so code is always genereted with instructions which are available on the Nehalem microarchitecture (up to SSE4.2) * compiler -mtune= parameter is added so code is optimized for corei7-avx which equals to Sandy Bridge microarchitecture * set of macros is added which allows run-time detection of available cpu instructions (e.g. clib_cpu_supports_avx()) * set of macros is added which allows us to clone graph node funcitons where cloned function is optmized for different microarchitecture Those macros are using following attributes: __attribute__((flatten)) __attribute__((target("arch=core-avx2))) I.e. If applied to foo_node_fn() macro will generate cloned functions foo_node_fn_avx2() and foo_node_fn_avx512() (future) It will also generate function void * foo_node_fn_multiarch_select() which detects available instruction set and returns pointer to the best matching function clone.

Allows DPDK parameters to be overriden from the platform definition. $(PLATFORM)_dpdk_arch = "armv7a" $(PLATFORM)_dpdk_target = "arm-armv7a-linuxapp-gcc" $(PLATFORM)_dpdk_make_extra_args = "CONFIG_RTE_EAL_IGB_UIO=y" Change-Id: I8c0f233942744cb82ca3ed2d65e33acee845cb4e Signed-off-by: Christophe Fontaine <christophe.fontaine@qosmos.com>

2016-04-18Add support for AArch32Christophe Fontaine1-0/+37
gcc version 4.9.2 (Raspbian 4.9.2-10) Tested on Linux raspberrypi 4.4.6-v7+ #875 SMP Tue Apr 12 16:33:02 BST 2016 armv7l GNU/Linux CPUs may be little or big endian, detect with gcc flags, not the processor architecture Add a new flag $(PLATFORM)_uses_openssl which allows to disable the link with openssl lib. vlib/vlib/threads.c: startup.conf must: - specify the heapsize as we don't have hugepages on raspbian cpu { main-core 3 } heapsize 64M Corrects in various files the assumption uword == u64 and replaces 'u64' cast with 'pointer_to_uword' and 'uword_to_pointer' where appropriate. 256 CPUs may create an OOM when testing with small memory footprint ( heapsize 64M ), allows the number of VLIB_MAX_CPUS to be set in platforms/*.mk vppinfra/vppinfra/longjmp.S: ARM - copy r1 (1st parameter of the setjmp call) to r0 (return value) vppinfra/vppinfra/time.h: On ARMv7 in AArch32 mode, we can access to a 64bit register to retreive the cycles count. gcc on rpi only declare ARM_ARCH 6. Override this info, and check if it is possible to use 'mrrc'. /!\ the time function will NOT work without allowing the user mode access to the PMU.

2015-12-16Add vppctl as a simple cli interface to vppEd Warnicke1-1/+1
This patch provides a pretty simple hack on top of vpe_api_test to give users a cli interface to vpp. Example: sudo vppctl show api client sudo vppctl show int It has the advantage that users can use bash shell scripting and history with it.
