Is there a way for the Linux Kernel to know the cache line size of the
CPU it's on, besides #define X86_CACHE_LINE_SZ 32 or whatnot? I am
looking in /proc/cpuinfo trying to determine how to run caching
optimizations and interested in this information and its implications.
It may also be useful if I can get this information at run time in
application code.
You can use /dev/cpu/x/cpuid to read it directly from the CPU.
See the source of x86info for examples.
