** Description changed:
- After updating to 5.0.0-25-generic kernel, battery life is considerably
- less and power consumption is about 10 watts more idle, using integrated
- graphics. This is a hybrid GPU laptop Intel HD 630/GP107M, and a
- possible cause is not powering off the dedicated GPU completely while
- using the integrated.
+ === SRU Justification ===
+ [Impact]
+ Some Nvidia graphics card has audio function in addition to video
+ function. When the video function is not bound to any driver, the audio
+ function can't be runtime suspended, hence preventing the power
+ resources from being turned off.
+
+ [Fix]
+ Allow Nvidia audio function to be runtime suspended.
+
+ [Test]
+ The user reported the fix works.
+
+ [Regression Potential]
+ Low. It only allows the audio function of discrete Nvidia GPU to be
+ runtime suspended. Regular audio or audio function with a discrete GPU
+ already bound to a driver are unaffected.
