Judging by the igt commit Paulo has a fix for this, but I haven't yet recovered from the mail flood. Hi The current drm-intel-nightly tree has some problems with runtime PM, so none of the current tests are passing. I already submitted patches to fix that: "[PATCH 0/6] More runtime PM fixes". The fix for this specific bug is "[PATCH 3/6] drm/i915: get runtime PM at i915_reg_read_ioctl", which can be found here: http://lists.freedesktop.org/archives/intel-gfx/2014-March/041364.html Thanks, Paulo Hi Patch "drm/i915: get runtime PM at i915_reg_read_ioctl" was merged on -fixes, and I'm pretty sure it fixes the reported bug. If the bug still happens, please reopen the bug report. Thanks, Paulo Verified.fixed. Closing old verified. |
