** Description changed: [Impact] Any of the platforms we’ve been seeing SATA problems not going to deepest state leading to other devices not getting there during long idle or s2idle. And it also prevents the system from entering deeper PC state other than PC3. - [Test] - Verified the power consumption on some new platforms, it doesn't do too much difference to the numbers, but it improves. [Fix] - Suggested from Intel and Dell to contains the 2 commits + 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 production machines with suspend-to-idle enabled should have the DEVSLP function been validated. - - [Misc] - Those commits do not show up in any public git tree yet, so let's verify - them in oem kernel first, and then will submit to bionic kernel later. + Low, the DEVSLP function is already validated when shipped with SLP_S0 + support.
