== Comment: #8 - Akshay Adiga <aksadiga@in.ibm.com> - 2018-05-16 13:29:55 ==
Patch is posted on linux mailing list
https://patchwork.ozlabs.org/patch/914575/ |
== SRU Justification ==
During testing, IBM found that cpupower idle-info is not listing stop4 and
stop5 idle states when all CORES are guarded. A patch has been
submitted upstream by IBM. However, the patch has not landed in
linux-next or mainline as of yet. For that reason, this SRU request is
being sent as a SAUCE patch request.
== Fix ==
UBUNTU: SAUCE: cpuidle/powernv : init all present cpus for deep states
== Regression Potential ==
Low. Limited to powerpc.
== Test Case ==
A test kernel was built with this patch and tested by the original bug reporter.
The bug reporter states the test kernel resolved the bug.
