2016-05-25Move dpdk startup config data to separate structDamjan Marion1-1/+1
This is preparation work for moving DPDK EAL and mempool initialization to vlib. Change-Id: I2dc35aa53edec0e07fc2650d630aa625831154c3 Signed-off-by: Damjan Marion <damarion@cisco.com>
2016-05-19Add support for multiple microarchitectures in single binaryDamjan Marion1-0/+1
* 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.

2016-04-22Add a vpp_restart commandDave Barach1-0/+1
vpp_restart solves the problem of restarting vpp and not exiting until the new vpp instance is sufficiently established to allow immediate binary API connections. The point is to avoid using arbitrary "sleep N" commands e.g. in CSIT shell scripts. We send SIGTERM to the current vpp process, and expect / depend on the process-monitor du jour to remove the vpp-api shared-memory segment. vpp_restart exits w/ status 0 if all is well, non-zero upon failure. In trying to make vpp_restart reliable, we discovered a recently-introduced heap corruption bug in .../dpdk/init.c, which caused vpp to crash on startup once every 20 times on a particular rig. If possible, we should check /var/log/syslog for evidence of unexpected multiple restarts during regression-testing.
