[Bug 2054304] Re: [SRU] Jammy RISC-V nezha and licheerv (allwinner kernel) images failing to build

[Łukasz Zemczak]

Hello Łukasz, or anyone else affected,

Accepted flash-kernel into jammy-proposed. The package will build now
and be available at https://launchpad.net/ubuntu/+source/flash-
kernel/3.104ubuntu19 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-
jammy to verification-done-jammy. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-
failed-jammy. 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.

** Changed in: flash-kernel (Ubuntu Jammy)
       Status: In Progress => Fix Committed

** Tags added: verification-needed verification-needed-jammy

Title:
  [SRU] Jammy RISC-V nezha and licheerv (allwinner kernel) images
  failing to build

Status in flash-kernel package in Ubuntu:
  Invalid
Status in flash-kernel source package in Jammy:
  Fix Committed

Bug description:
  [ Impact ]

  The new allwinner kernel in jammy (20.04) no longer has the
  "-allwinner" flavour suffix, but "-generic". This results in flash-
  kernel failing to match the kernel when running (and f-k failing to
  run causes apt upgrade to fail). The "Kernel-Flavor:" field for all
  boards which are currently limited to "allwinner riscv64" should be
  changed to "any"; this matches the state in noble.

  
  [ Test Plan ]

  There are three entries in the f-k database which are affected:

  * Allwinner D1 Nezha
  * Sipeed Lichee RV
  * Sipeed Lichee RV Dock

  Ideally, a jammy image should be tested on each of these three boards
  as follows:

  * Install jammy image
  * Enable proposed (https://wiki.ubuntu.com/Testing/EnableProposed)
  * sudo apt install -t jammy-proposed flash-kernel
  * sudo apt update; sudo apt full-upgrade
  * Upgrade should run successfully without apt dying during flash-kernel
  * Verify freshly installed kernel is from the 6.5 series and is "-generic" flavour
  * sudo reboot
  * Check system reboots and is operational afterward

  
  [ Regression Potential ]

  Database changes in flash-kernel should only affect the listed boards,
  and the move to "any" makes the entry less restrictive which is
  generally a "safer" change. However if, for any reason, one of these
  boards has an unsupported kernel flavour with a later version
  installed, that will cause a regression as flash-kernel will now
  select that kernel for installation. This shouldn't be the case in any
  supported configuration, but is a possibility to be aware of.

  
  [ Original Description ]

  Since the beginning of the year, all jammy -allwinner kernel based
  images are failing to build, aka. the nezha and licheerv subarch ones.
  It looks like the problem is with the new allwinner kernel, now
  needing some changes to flash-kernel to properly handle it during DTB
  preparation.
