And it also prevents the system from entering deeper PC state other than PC3. [Fix] Suggested from Intel and Dell to contains the following 4 commits, and all of 4 commits are in v4.19-rc1 https://patchwork.kernel.org/patch/10502285/ https://patchwork.kernel.org/patch/10502287/ https://patchwork.kernel.org/patch/10535781/ https://patchwork.kernel.org/patch/10535783/ [Test] Verified the power consumption on some new platforms, it improves the SATA HDD power consumption around 0.5w during long idle. [Regression Potential] Low, the DEVSLP function is already validated when shipped with SLP_S0 support.
