Bug description:
  [Impact]
  On new systems that facilitate s2idle, we observed the power consumption 
raises higher than long idle does during s2idle with Western Digital PC SN720 
NVMe SSD SDAPNTW-256G.

  Short idle: 5.3
  Long idle: 3.0
  S2I: 5.07

  [Fix]
  Windows doesn't put nvme to D3 in modern standby, and uses its own APST 
feature to do the power management. To leverage its APST feature during s2idle, 
we can't disable nvme device while suspending, too.
  So, here is what we did on the driver, 1. prevent nvme from entering D3, 2. 
prevent nvme from being disabled when suspending.

  [Test]
  Verified on the WD NVMe, it fixes the power consumption issue with no 
regression. And the power consumption decreases to 1.66W during s2idle.

  [Regression Potential]
  Low, the patches only applied to specific nvme module, and from our test, the 
system is still stable.

[Kernel-packages] [Bug 1805775] Re: PC SN720 NVMe WDC 256GB consumes more power in S2Idle than during long idle

2019-01-15 Thread Brad Figg 
This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
cosmic' to 'verification-done-cosmic'. If the problem still exists,
change the tag 'verification-needed-cosmic' to 'verification-failed-
cosmic'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

  [Impact]
  On new systems that facilitate s2idle, we observed the power consumption 
raises higher than long idle does during s2idle with Western Digital PC SN720 
NVMe SSD SDAPNTW-256G.

  Short idle: 5.3
  Long idle: 3.0
  S2I: 5.07

  [Fix]
  Windows doesn't put nvme to D3 in modern standby, and uses its own APST 
feature to do the power management. To leverage its APST feature during s2idle, 
we can't disable nvme device while suspending, too.
  So, here is what we did on the driver, 1. prevent nvme from entering D3, 2. 
prevent nvme from being disabled when suspending.

  [Test]
  Verified on the WD NVMe, it fixes the power consumption issue with no 
regression. And the power consumption decreases to 1.66W during s2idle.

  [Regression Potential]
  Low, the patches only applied to specific nvme module, and from our test, the 
system is still stable.
