2018-06-04Configure or deduce CLIB_LOG2_CACHE_LINE_BYTES (VPP-1064)Dave Barach1-1/+4
Added configure argument "--with-log2-cache-line-bytes=5|6|7|auto" AKA 32, 64, or 128 bytes, or use the inferred value from the build host. produces build-xxx/vpp/vppinfra/config.h, which .../src/vppinfra/cache.h Kernels which implement the following pseudo-file (aka x86_64) are easy: /sys/devices/system/cpu/cpu0/cache/index0/coherency_line_size Otherwise, extract the cpuid from /proc/cpuinfo and map it to the cache line size.
