I can find the details from the email thread. HSW/BSW need acquire the power because it is inside the gpu.

SKL is different from HSW/BDW. HSW/BDW has 2 audio controllers. One is in PCH and another is in gfx. SKL has one controller, which is in PCH. Both HSW/BDW and SKL has display audio codec in gfx. For HSW/BDW, to use the controller inside gfx, we must get the gfx power. For SKL, to use the controller, we don't need to get the gfx power. For both HSW/BDW and SKL, to use display audio codec, we must get the gfx power. Without the patch, all the audio controllers except BYT/BSW will get the gfx power. However this is not true, SKL and APL audio controller don't need this power. - /* Baytral/Braswell controllers don't need this power */ - if (pci->device != 0x0f04 && pci->device != 0x2284) + /* HSW/BDW controllers need this power */ + if (CONTROLLER_IN_GPU(pci)) hda->need_i915_power = 1; For skl, it need to get gfx power only when display audio codec is used, this is set in the patch: + if (is_valleyview_plus(codec) || is_skylake(codec)) codec->core.link_power_control = 1; Without the patch, SKL may consume gfx power even it doesn't need. This patch has been tested by our full test cases for about one year, it shows the right result. Do you think maybe there is another recent patch cause this issue? I will debug the Bugzilla next week on audio side.
