Hi Li Peng,
you are absolutely right. I reverted the patch "drm/i915: remove
render reclock support" on 18.104.22.168 and Im back to 10w idle :-)
Do you think that using the kernel with this reversed patch is safe? I
didn't have any problem before it was reversed (i had to remove some
IS_IRONLAKE checks but that doesn't apply to me, i have a GM45).
thank you for your interest, please let me know if you still need the
debug logs you requested!
