SRU: Backport the latest developments on drivers detection and hybrid graphics

[Alberto Milone]

As we introduced the "-server" NVIDIA drivers, and the concept of "LTSB" (Long Term Support Branch) and "NFB" (New Feature Branch) releases, the detection logic behind ubuntu-drivers needs an update to make the correct choices for the user.

The introduction of the NVIDIA 450 series, also added runtime power management, which greatly improves user experience on systems with hybrid graphics, and allows greater power savings. When supported, on-demand mode and runtime power management are the default. Both gpu-manager and ubuntu-drivers in ubuntu drivers common, and the tools in the nvidia-prime package need updating as a result.

The nvidia-prime package also has a change to fix a problem where /lib/udev/rules.d/50-pm-nvidia.rules was left behind, after a system upgrade 20.04 LTS (focal) to 20.10 (groovy), and yet prime-select had lost the ability to remove the udev rules file, leaving the end user with no means to re-enable his/her Nvidia GPU.

Only the components in Ubuntu 20.10 require a fairly small diff for the backport. The rest is a direct sync of the 1:0.8.6.3 release in 21.04.

[Impact]

* The ubuntu-drivers tool might install the wrong driver, or, in some cases, crash, if the new -server drivers are available.

* The new runtime power management can't be used even when the hardware (Turing GPUs or newer) supports it.

* We want to the default drivers to be Long Term support releases. Users may still pick different drivers manually.

[Fix]

* The code in Ubuntu 21.04 includes essential bug fixes, and more test cases in the test suite, to make sure that driver installation is more robust, and more accurate (LTSB vs NFB releases, and non-server vs -server releases).

* ubuntu-drivers, gpu-manager, and prime-select now all support runtime power management.

[Test Case]
Install ubuntu-drivers-common and nvidia-prime from proposed, and check the following:

1) ubuntu-drivers debug

2) Make sure no nvidia driver is installed (sudo apt-get --purge remove '*nvidia*', and try installing an nvidia driver with "sudo ubuntu-drivers install"

3) Reboot your system

4) [optional] If you are running on a hybrid laptop, you can check if your system supports runtime power management:

sudo prime-select on-demand

(if you are already in "on-demand" mode, select "intel" mode first, then try "on-demand" again)

5) If you followed step 4, reboot again

6) Attach your /var/log/gpu-manager.log

[Regression Risk]
Medium, while this code includes many fixes, it needs careful testing.

This SRU is blocked from being accepted by an already existing ubuntu-drivers-common waiting for validation in groovy-proposed (SRU bug LP: #1900452). We'd need to first get that one verified and released before considering the next one.

[Steve Langasek (vorlon)]

Reviewing the nvidia-prime upload in the queue, I do not understand the rationale for this SRU change. The changelog states that we are removing "obsolete udev rules during upgrade". However, this means that the udev files on disk will only removed when upgrading *from* this package version; so users installing this SRU will still have those files on disk. If your intent is to have them removed upon installation of *this* package version, then the removal should happen in the postinst, not in the postrm.

It would be helpful if you would lay out in this bug what your intent is with this change.

[Alberto Milone (albertomilone)]

Ok, I have uploaded new nvidia-prime packages.

I just verified on focal on a machine with BIOS ID:097E (202005-27873):
 - kernel : 5.6.0-1042-oem

$ apt list nvidia-prime ubuntu-drivers-common
Listing... Done
nvidia-prime/focal,focal,now 0.8.14 all [installed,automatic]
ubuntu-drivers-common/now 1:0.8.6.3~0.20.04.2 amd64 [installed,local]

$ sudo cat /sys/class/dmi/id/bios_version
1.4.0
$ sudo cat /sys/class/dmi/id/product_sku
097E

The Nvidia device sleep as expected. (checked by powertop)
The Nvidia renderer works as expected when the user execute an application with "Launch using Dedeicated graphic card"

Thank you for the verification! Since we are slowly preparing things for .2, I will release the ubuntu-drivers-common SRUs a day early from their usual 7-day aging period.

Package FTBFS on arm64 for bionic - maybe a retry is needed?

[Łukasz Zemczak (sil2100)]

Also, once the FTBFS is resolved, this is still blocked on LP: #1915003.

[Alberto Milone (albertomilone)]

FTBFS is gone, and I have verified LP: #1915003.

This bug was fixed in the package nvidia-prime - 0.8.16~0.18.04.1

---------------
nvidia-prime (0.8.16~0.18.04.1) bionic; urgency=medium

  * prime-select:
    - Make sure to update the initramfs, so that
      the driver options can be applied correctly.
      This time around we can also provide visual
      feedback (in the form of a progress spinner)
      while update-initramfs is running (LP: #1915003).
