** Merge proposal linked: https://code.launchpad.net/~cypress-team/livecd-rootfs/+git/livecd-rootfs/+merge/486094 ** Description changed: [ Impact ] + + * This is a hardware enablement SRU. * In partner engineering, we maintain specific nvidia hardware which require a dedicated optimized kernel. We need to build Desktop images for these machines, on a regular basis, to run the certification suites. Right now the kernel we need is `linux-nvidia-hwe-24.04-edge`, but I'm anticipating that it will be `linux-nvidia-hwe-24.04` at some point so this should be possible to configure. * The resolution involves adding a subarchitecture (SUBARCH) option in Desktop images which, when provided, will behave accordingly. a CHANNEL option can also be provided to add the channel. [ Test Plan ] 1. Create a Desktop ISO. It will contain the generic kernel. 2. Create a Desktop ISO with the proposed package. It will contain the generic kernel too. 3. Create a Desktop ISO after mentioning subarch=nvidia in the metadatas. The kernel should now be nvidia's. 4. Create a Desktop ISO after mentioning subarch=nvidia in the metadatas. The kernel should now be nvidia's edge. 5. Build the images from 3, 4, 5 with ubuntu-cdimage and test that they boot correctly and have the right kernel. Please not that the debian-cd branch to be used it the following merge proposal: https://code.launchpad.net/~antoinelassagne/debian-cd/+git/debian-cd/+merge/485191 - 6. Redo all these steps with Live Server image + 6. Redo all these steps with Live Server image [ Where problems could occur ] * If the bash scripts becomes invalid or go in the wrong branch, the image build process could simply stop working, or provide images with the wrong kernel. The test plan reflects this risk. + + [ Other Info ] + + * The kernel that are made available with this fixed are only released + on LTS series right now. To test it on non LTS series, we'd have to + package the kernel into a private PPA before. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2109822 Title: Add support for building ARM64 images with nvidia kernels in noble To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/livecd-rootfs/+bug/2109822/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
