From: Paulo Zanoni <paulo.r.zanoni@xxxxxxxxx> Hi This is a resend of the patches I have that fix the runtime PM WARNs we get while running IGT's pm_pc8 test on Haswell. Right now, runtime PM is completely broken and these patches should put it back to the state where it was before. The issue fixed by the first patch completely breaks runtime PM, so we don't have Bugzilla tags for the other issues because our QA couldn't even discover them due to the lack of the first patch on our trees. I have tested this series locally on my Haswell machine and it works. Thanks, Paulo Paulo Zanoni (7): drm/i915: don't schedule force_wake_timer at gen6_read drm/i915: get runtime PM at i915_reg_read_ioctl drm/i915: don't read pp_ctrl_reg if we're suspended drm/i915: get runtime PM at i915_display_info drm/i915: don't read cursor registers on powered down pipes drm/i915: fix WARNs when reading DDI state while suspended drm/i915: don't get/put runtime PM at the debugfs forcewake file drivers/gpu/drm/i915/i915_debugfs.c | 18 ++++++++++-------- drivers/gpu/drm/i915/intel_ddi.c | 5 +++++ drivers/gpu/drm/i915/intel_dp.c | 3 ++- drivers/gpu/drm/i915/intel_pm.c | 3 +++ drivers/gpu/drm/i915/intel_uncore.c | 20 +++++++++++++------- 5 files changed, 33 insertions(+), 16 deletions(-) -- 1.8.5.3 _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/intel-gfx
