Dear list, I've previously had an issue with my Dell Laptop (Latitude E5520) which has a i915 graphics card on a Sandy Bridge (2011-12-13 "Fan running with Intel Graphics"). The fan was running because apparently the GPU was not going into powersave mode.
Now, by sheer stupidity on my part, I've lost my kernel configuration and the (working) kernel image. So I embarked on the journey to retrieve the latest git and see how it goes. Sadly, the running fan is back: I've checked out drm-intel-testing, rev. c3c3d4e9. My kernel command line looks like this: pcie_aspm=force i915.i915_enable_rc6=3 i915.lvds_downclock=1 i915.i915_enable_fbc=1 nomodeset Previously, I've always done echo 400 >/sys/kernel/debug/dri/0/i915_max_freq but with this kernel revision, /sys/kernel/debug/dri/ is empty and there's no i915_max_freq node anywhere to be found within /sys. Should I update to a different branch? Should I change the kernel command line? Or are there other options? Any advice is greatly appreciated, All the best, Joe _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx
