From 3bd5a5fc8c6b9fe769777abf74b0ab5fbd7930b4 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Fri, 28 Jun 2013 16:22:19 +0300 Subject: perf tools: Add test for converting perf time to/from TSC The test uses the newly added cap_usr_time_zero and time_zero of perf_event_mmap_page. TSC from rdtsc is compared with the time from 2 perf events. The test passes if the calculated times are all in the correct order.
