| H A D | turbostat.c | e52966c0 Thu Nov 08 21:38:05 CST 2012 Len Brown <len.brown@intel.com> tools/power turbostat: prevent infinite loop on migration error path
Turbostat assumed if it can't migrate to a CPU, then the CPU
must have gone off-line and turbostat should re-initialize
with the new topology.
But if turbostat can not migrate because it is restricted by
a cpuset, then it will fail to migrate even after re-initialization,
resulting in an infinite loop.
Spit out a warning when we can't migrate
and endure only 2 re-initialize cycles in a row
before giving up and exiting.
