Hi All, This is how I would fix the issue reported in BZ 200759 (see this patch series from Yu too: https://marc.info/?l=linux-pm&m=155137672924029&w=2).
Patch [1/2] causes intel_pstate to update all policies if it gets a _PPC change notification and sees a global turbo disable/enable change. Patch [2/2] makes it update cpuinfo.max_freq for all policies in those cases. The patches here have not been tested yet, so testing would be much appreciated. Of course, comments are welcome too! Thanks, Rafael
