Title: AX201 BT will cause system could not enter S0i3 Status in HWE Next: New Status in linux package in Ubuntu: In Progress Status in linux-oem-5.10 package in Ubuntu: Invalid Status in linux-oem-5.13 package in Ubuntu: Invalid Status in linux source package in Focal: Confirmed Status in linux-oem-5.10 source package in Focal: Fix Released Status in linux-oem-5.13 source package in Focal: Fix Released Status in linux source package in Hirsute: Fix Released Status in linux source package in Impish: In Progress Status in linux-oem-5.10 source package in Impish: Invalid Bug description: [Impact] Platforms with AX201 BT fail to pass the power consumption tests [Fix] Intel provides us the patch to fix it. https://patchwork.kernel.org/project/intel-gfx/patch/20210325120947.11950-1-anshuman.gu...@intel.com/ Wa_14010685332 sequence toggles a SDE chicken bit on and then off as the final step when disabling interrupts in preparation for runtime suspend. And this sequence also fixes the issues that dispcnlunit1_cp_xosc_clkreq clock keeps to be active on TGL-H during s2idle. v2. 8b46cc6577f4 drm/i915: Tweaked Wa_14010685332 for all PCHs [Test] Verified on the Dell machines with AX201 BT on them. [Where problems may occur] This patch extend the s0ix fix from gen8 and gen11 to CNP, ICP, JSP, MCC, TGP, and ADP PCHs, and also move the Wa_14010685332 sequence from reset functions to suspend/resume functions. It won't affect old chips as there is a if statement to check the pch type, and new chips require this sequence to work well.
