** Description changed: [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/[email protected]/ + 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 for gen8 and gen11 to all PCHs. Not sure if it will lead to regressions on different PCH. + 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.
