1These tests (preempt_timing and rdtsc_latency) are intended 2to be tools to diagnose problems if gtod_latency results are 3problematic. 4 5We don't run these tests by default (top level run.sh script 6will not list them, as it won't find run_auto.sh). 7 8They can be run from this test directly by invoking the 9local run.sh script. 10
