The test tests/cp/proc-short-read.sh attempts to remove common differences in the output of /proc/cpuinfo: # adjust varying parts sed '/MHz/d; /bogomips/d;' 1 > proc.cp || framework_failure_ sed '/MHz/d; /bogomips/d;' 2 > proc.cat || framework_failure_ However the string "bogomips" may differ in capitalization across different architectures [1]. Testing on a big.LITTLE system uncovered this assumption.
