[Bug 2069802] Re: [SRU] flash-kernel to support xilinx kria platforms with noble kernel

[Timo Aaltonen]

Hello Talha, or anyone else affected,

Accepted flash-kernel into oracular-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/flash-
kernel/3.107ubuntu13~24.10.1 in a few hours, and then in the -proposed
repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
oracular to verification-done-oracular. If it does not fix the bug for
you, please add a comment stating that, and change the tag to
verification-failed-oracular. In either case, without details of your
testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)
fixed by this package have been verified and the package has been in
-proposed for a minimum of 7 days.

Title:
  [SRU] flash-kernel to support xilinx kria platforms with noble kernel

Status in flash-kernel package in Ubuntu:
  Fix Released
Status in flash-kernel source package in Noble:
  Fix Committed
Status in flash-kernel source package in Oracular:
  Fix Committed

Bug description:
  [ Impact ]

   * With the current version of flash-kernel, users wont be able to
  boot into xilinx devices using optimised noble kernel because of the
  renaming of device-trees in kernel and cma configuration changes.

   * We need to fix this issue to keep support for xilinx devices in
  noble as well. This must not be back-ported into jammy since the
  kernel in jammy keeps the old names for device-trees and cma
  configuration in there didn't change

   * Patch will fix the issue by updating bootscript and `its` file to
  point correct device-tree files.

  [ Test Plan ]

   * Flash the new image generated with new flash-kernel that has this fix
   * Try booting with new image
   * You should be able to reach the login prompt and be able to login using default username and password
   * This must work for all Kria devices listed below:
    - KV260
    - KR260
    - KD240

  [ Where problems could occur ]
   * This change could only impact Xilinx Kria devices since it will only touch the files used by Xilinx Kria platforms including the ones listed above in test plan
   * Since this is an enablement patch for Ubuntu Noble image on Xilinx Kria platforms, there shouldnt be an impact to devices in the field.
   * If the patch is broken then the devices listed above will still continue to not work.

  [ Other Info ]
   
   * This is based on changes in new optimised kernel: https://code.launchpad.net/~canonical-kernel/ubuntu/+source/linux-xilinx/+git/noble
