This bug was fixed in the package flash-kernel - 3.104ubuntu6 --- flash-kernel (3.104ubuntu6) jammy; urgency=medium * Introduce "Boot-Kernel-Max-Size" and support for compressing kernel images that exceed it. This will allow installation of larger uncompressed kernels on HP ProLiant m400 cartridges. LP: #1954692 * Drop support for HP ProLiant m800 cartridges. The kernel flavor they require (-keystone) never shipped in Ubuntu. -- dann frazier Mon, 31 Jan 2022 16:47:18 + ** Changed in: flash-kernel (Ubuntu) Status: In Progress => Fix Released -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1954692 Title: Reconsider compressed kernels on arm64 To manage notifications about this bug go to: https://bugs.launchpad.net/maas-images/+bug/1954692/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1954692] Re: Reconsider compressed kernels on arm64
@juliank my assumption is that nothing prevents it, other than someone writing that code. Attached is a patch for flash-kernel that will handle the compression, if needed, of kernel images for the m400. One alternate solution might be to try and copy the firmware-provided device tree data into a different memory location before loading the kernel in the boot.scr script. On one hand, that would limit the changes to code that only runs on these devices. But on the other hand, the generated uImage/uInitrd files wouldn't be usable for netbooting, as I don't think there's a way to inject memory copy commands into a config file for u-boot's pxelinux emulation. Note that we'll need to update the MAAS image generation code as well to keep that working. ** Patch added: "0001-Introduce-Boot-Kernel-Max-Size-and-support-for-compr.patch" https://bugs.launchpad.net/ubuntu/+source/flash-kernel/+bug/1954692/+attachment/5557834/+files/0001-Introduce-Boot-Kernel-Max-Size-and-support-for-compr.patch ** Also affects: maas-images Importance: Undecided Status: New ** Changed in: flash-kernel (Ubuntu) Status: New => In Progress ** Changed in: flash-kernel (Ubuntu) Assignee: (unassigned) => dann frazier (dannf) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1954692 Title: Reconsider compressed kernels on arm64 To manage notifications about this bug go to: https://bugs.launchpad.net/maas-images/+bug/1954692/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1954692] Re: Reconsider compressed kernels on arm64
My side question is what prevents arm64 from having the amd64 approach where AFAIUI the image is compressed but starts with a small stub that decompresses it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1954692 Title: Reconsider compressed kernels on arm64 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1954692/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
