[Bug 2141545] Re: [SRU] add swap file or partition to LicheeRV preinstalled image

[Heinrich Schuchardt]

I build with what is in proposed for the Nezha an LicheeRV board in
https://launchpad.net/~xypron/+livefs/ubuntu/noble/test/+build/943158
https://launchpad.net/~xypron/+livefs/ubuntu/noble/test/+build/943159

The Nezha board boots fine and shows:

ubuntu at ubuntu:~$ cat /etc/fdisk
cat: /etc/fdisk: No such file or directory
ubuntu at ubuntu:~$ cat /etc/fstab 
LABEL=cloudimg-rootfs   /        ext4   discard,commit=30,errors=remount-ro     0 1
LABEL=UEFI      /boot/efi       vfat    umask=0077      0 1
/swapfile       none    swap    sw      0       0
ubuntu at ubuntu:~$ free
               total        used        free      shared  buff/cache   available
Mem:          973704      210188      540816         984      302084      763516
Swap:        1048572           0     1048572

The LicheeRV shows this output:

ubuntu at ubuntu:~$ cat /etc/fstab 
LABEL=cloudimg-rootfs   /        ext4   discard,commit=30,errors=remount-ro     0 1

Title:
  [SRU] add swap file or partition to LicheeRV preinstalled image

Status in livecd-rootfs package in Ubuntu:
  Invalid
Status in livecd-rootfs source package in Noble:
  Fix Committed

Bug description:
  [ Impact ]

  A kernel upgrade from linux-allwinner 6.8 to linux-generic 6.17 fails
  due to the limited board memory (512 MiB) on the LicheeRV Dock. The
  Allwinner Nezha D1 is also memory constrained.

  Add 1 GiB of swap space.

  Both boards use the RISC-V RVA20 ISA and are not supported in
  Questing, Resolute.

  [ Test Plan ]

  Create and boot a preinstalled LicheeRV and a Allwinner Nezhal D1
  image.

  Check that /etc/fstab contains a swap entry.

  Run the `free` command to check the swap space.

  [ Where problems could occur ]

  The change might impact other images or even result in build failures
  if done incorrectly.

  [ Other Info ]
