[Bug 2127473] Re: [SRU] Update linux-firmware-nvidia-tegra to 38.2.2

Thu Dec 11 13:45:54 UTC 2025

Hi Dave, let me try to bring some answers

1a. Indeed there are no plucky or questing images, as there are no
customized kernel for those series. There's more context about upgrades
in https://bugs.launchpad.net/ubuntu/+source/nvidia-tegra-
defaults/+bug/2127100 but basically, that's something we are planning to
prevent in ubuntu-release-upgrader for the time being.

1b. I am gonna remove the Jammy/Orin part as indeed it is not relevant
anymore.

2. That's true indeed, but bluetooth is the only features that can be
tested with the image out of the box. Testing advanced features like
nvenv, nvjpeg, etc requires to install additional userspace packages
which are not in Ubuntu, as described in https://canonical-ubuntu-for-
jetson.readthedocs-hosted.com/classic/installation-noble/#install-
nvidia-proprietary-software.

Note that this noble upload fixes the following bugs:
- https://bugs.launchpad.net/riverside/+bug/2122501
- https://bugs.launchpad.net/riverside/+bug/2122571 (but this requires a 4K monitor connected, which explains why the test plan doesn't mention it)

3. Correct, I am going to rephrase the test plan.

Bug description:
  [ Impact ]

   * Updates the /lib/firmware files for the NVIDIA Tegra Jetson Orin devices with Jetson Linux v38.2.2
   * Includes new firmware files for NVIDIA Tegra Jetson Thor devices
   * Firmware updates are necessary to guarantee full compatibility with the linux-nvidia-tegra kernel for noble
   * The target series for this change are noble
   * Most importantly, this update ships firmware for display and bluetooth

  [ Test Plan ]

  Thor (noble):
   * Boot a Jetson AGX Thor from current Ubuntu for Jetson early access image (https://people.canonical.com/~platform/images/nvidia-tegra/ubuntu-24.04-preinstalled-server-thor-arm64+jetson.img.xz)
   * Update to latest packages and reboot
   * Run "$ sudo apt install -y bluez && sudo hciconfig" and observe the following output:

  hci0: Type: Primary Bus: USB
          BD Address: 00:00:00:00:00:00 ACL MTU: 0:0 SCO MTU: 0:0
          DOWN
          RX bytes:0 acl:0 sco:0 events:0 errors:0
          TX bytes:0 acl:0 sco:0 commands:0 errors:0

   * Install linux-firmware-nvidia-tegra from noble-proposed
   * Reboot, run "$ sudo hciconfig" and observe something along the following:

  ubuntu at ubuntu:~$ sudo hciconfig
  hci0:	Type: Primary  Bus: USB
   BD Address: C0:BF:BE:85:53:09  ACL MTU: 1021:8  SCO MTU: 255:12
   UP RUNNING
   RX bytes:1541 acl:0 sco:0 events:109 errors:0
   TX bytes:2528 acl:0 sco:0 commands:109 errors:0

  [ Where problems could occur ]

   * A firmware file update can introduce a regression. The impact will
  be limited on the Jetson devices only, and this should be detected by
  our automated test jobs during the SRU process.

  [ Other Info ]

   * 38.2.2 is related to Nvidia Jetpack 7.0 release: https://docs.nvidia.com/jetson/archives/r38.2.1/ReleaseNotes/Jetson_Linux_Release_Notes_r38.2.1.pdf
