Bhat <shigb...@in.ibm.com> - 2015-05-06 07:24:11 == The user can see a drop in performance when frequency is throttled and is unaware of throttling. So detect and report such a condition, so the user can check the OCC status to reboot the system or check for power supply or fan failures. The cpu frequency can be throttled by OCC for the following reasons: 1)If a processor crosses its power and temperature limit then OCC will lower its Pmax to reduce the frequency and voltage. 2)If OCC crashes then the system is forced to Psafe frequency. 3)If OCC fails to recover then the kernel is not allowed to do any further frequency changes and the chip will remain in Psafe. This bug is fixed upstream 09a972d1620934142d30cfda455ffe429af751c4 ---uname output--- 3.19.0-15 Machine Type = llmtul02b.in.ibm.com Contact Information = Shilpasri G Bhat / shilpa.b...@linux.vnet.ibm.com To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1452547/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
