2014-10-07 11:06 GMT-03:00 Rodrigo Vivi <rodrigo.vivi@xxxxxxxxx>: > Avoid to expose RC6 and RC6pp to the platforms that doesn't support it. > So powertop can be changed to show RC6p and RC6pp only on the platforms > they are available. > > v2: Simplify by merging RC6p and RC6pp groups and respect the spec that > mentions deep and deepest RC6 on SNB and IVB although they keep disabled > by default. > > v3: Remove unecessary space. > > v4: RC6p and RC6pp is only for SNB and IVB; unify debug msg and use > has_rc6p() on sanitize options instead of is gen 6 and ivb. > > v5: yet another fix on has_rc6p macro. final is_gen6 or is_ivb!
