Could any expert give me a explain, please? It tests timer precision for getrusage timers. If the timers are incremting by larger values than expected, something is wrong in kernel. The precision depends on CONFIG_HZ settings which is represented by the BIAS_MAX. > And looks like with this patch applied, it works well on powerpc: Can you please share the output of the testcase on ppc and ppc64? What is the expected timer granularity there? -- Cyril Hrubis chrubis@suse.cz ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
