[Bug 1906668] [NEW] [MIR] opensbi

[Dimitri John Ledkov]

Public bug reported:

Availability:
in universe

Rationale:

opensbi is a bootloader/firmware component for riscv64. It is used by
qemu-system-riscv64 to load uboot-qemu firmware which then can load
kernel/initrd of a cloud-image to boot it.

It is also used as a build-dependency by u-boot, to create combined
uboot-spl (secondary program loader) image. Such a combind image of
opensbi+uboot+dtb can be used to create selfcontained bootable firmware
on an sd-card, to allow booting SiFive HiFive Boards.

Quality assurance:

The package simply provides a static datafile. It's upto qemu & u-boot
to consume it, which they do. The paths and features it provides are
fairly well defined with SBI specifications with uboot and kernel adhere
to.

Dependencies:

It is effectively freestanding ELF object without dependencies. Hence it
is packaged as arch:all package.

Standards compliance:

Packages files in multiarch locations for the supported platforms.

Maintenance:

In sync with Debian, to be maintained by Foundations, foundations-bugs
subscribed.


Background information:

Example usage with cloud-image is documented at
https://wiki.ubuntu.com/RISC-V

How it is used by u-boot can be seen in this diff

1ubuntu2_2020.10+dfsg-1ubuntu3.diff.gz


Security checks

https://github.com/riscv/opensbi/security/advisories There aren't any
published security advisories at the moment.

The code however runs in M-mode to interface with S-mode & HS-modes,
thus this is highly privileged code used as firmware.

No executables or shared libraries or daemons shipped. Does not open
ports.

** Affects: opensbi (Ubuntu)
     Importance: Undecided
         Status: Confirmed


** Tags: hirsute

** Changed in: opensbi (Ubuntu)
       Status: Incomplete => Confirmed
