Add support for AArch32
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.
