Created attachment 101131 [details] test script ==System Environment== -------------------------- Platform: Ivybrige kernel: (drm-intel-next-queued)868d665b43473e230d560d5186535270a3d57a19 ==kernel== -------------------------- -nightly: b438e8793c6d18b0998d75cdf8115a5898ed21d1 (fail) drm-intel-nightly: 2014y-06m-13d-22h-09m-12s integration manifest -queued: 868d665b43473e230d560d5186535270a3d57a19 (fail) drm/i915: Fix memory leak in intel_dsi_init() error path -fixes: 223a6f2b975ab35d93270ea1d4fb6e0ac6b27fe6 (fail) drm/i915/bdw: remove erroneous chv specific workarounds from bdw code ==Bug detailed description== --------------------------- GPU device frequency can't increase to the largest one. It stay on lowest frequency. Get GPU current frequency from /sys/class/drm/card0/gt_cur_freq_mhz ==Reproduce steps== ---------------------------- 1. ./gfxturbo.sh (I attach this script)
That test is not guaranteed to raise GPU freq at all, for it misses the most important detail - if all the glxgears are able to maintain 60fps then there is no issue with running at the minimum frequency. Please refine the test.
