It also impacts HSW. According to my bisection the first bad commit is: commit ec82cb793c9224e0692eed904f43490cf70e8258 Author: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Date: Fri Oct 24 14:51:32 2014 +0100 drm/i915: create a prepare phase for sprite plane updates It would be really nice if QA could provide bisection results in their regression bug reports :) This patch should fix it: http://patchwork.freedesktop.org/patch/35960/ (In reply to Paulo Zanoni from comment #3) > This patch should fix it: http://patchwork.freedesktop.org/patch/35960/ Fixed by this patch. output IGT-Version: 1.8-ge622850 (x86_64) (Linux: 3.18.0-rc2_kcloud_476aa3_20141103+ x86_64) Runtime PM support: 1 PC8 residency support: 0 Subtest universal-planes: SUCCESS (30.562s) real 0m32.800s user 0m0.084s sys 0m0.100s Fix from Paulo landed in dinq: commit e4e676f9850903c160c7f5467c04342152b147d2 Author: Paulo Zanoni <paulo.r.zanoni@intel.com> Date: Mon Nov 10 14:47:30 2014 -0200 drm/i915: use the correct obj when preparing the sprite plane Verified.Fixed. root@x-bdw05:/GFX/Test/Intel_gpu_tools/intel-gpu-tools/tests# time ./pm_rpm --run-subtest universal-planes IGT-Version: 1.8-gc049c39 (x86_64) (Linux: 3.18.0-rc3_drm-intel-nightly_9a7620_20141112+ x86_64) Runtime PM support: 1 PC8 residency support: 1 Subtest universal-planes: SUCCESS (22.161s) real 0m22.488s user 0m0.029s sys 0m0.049s root@x-byt06:/GFX/Test/Intel_gpu_tools/intel-gpu-tools/tests# time ./pm_rpm --run-subtest universal-planes IGT-Version: 1.8-gc049c39 (x86_64) (Linux: 3.18.0-rc3_drm-intel-nightly_9a7620_20141112+ x86_64) Runtime PM support: 1 PC8 residency support: 0 Subtest universal-planes: SUCCESS (32.951s) real 0m35.963s user 0m0.091s sys 0m0.130s Closing old verified. |
