[Bug 2026588] Re: [SRU] Copy OpenSBI 1.3 to Jammy and Lunar

[Robie Basak]

The agreed test plan also included these steps:

> * Run apt-get update, apt-get install, and execute an application.
> * Run snap install and execute an application.

But I don't see any mention of this in your verification reports. Was
this done?

Additionally bug 1995860 is not verified yet, and presumably we want to
release these three packages together?

Bug description:
  [ Impact ]

  We provide an image for the StarFive VisionFive 2 board. Upstream
  U-Boot now provides support for the board but it requires OpenSBI 1.3.
  We should strive to put a current U-Boot onto our preinstalled image.

  [ Test plan ]

  * Rebuild current u-boot package in ppa against new OpenSBI and test running Ubuntu 22.04/23.04 on QEMU, SiFive HiFive Unmatched, and PolarFire Icicle Kit with this U-Boot.
  * Use a rebuilt u-boot-nezha package to boot the Nezha D1.
  * Run apt-get update, apt-get install, and execute an application.
  * Run snap install and execute an application.

  [ Where problems could occur ]

  OpenSBI is only used directly when running a RISC-V emulation in QEMU
  with the bios parameter.

  For all real hardware OpenSBI is built into U-Boot SPL. So getting
  OpenSBI onto boards will require a rebuild of U-Boot.

  Theoretically upgrading OpenSBI could

  * stop RISC-V boards from booting
  * cause failures when the operating system calls into OpenSBI
  * cause failures when OpenSBI emulates missing instructions.

  [ Other Info ]

  Upgrading to the same OpenSBI 1.3 that we use in Mantic instead of
  applying selected patches to 22.04/23.04 is easier to maintain in the
  long run.
