RISC-V EFI support is not yet in the Linux kernel (ca. 5.8: https://lkml.org/lkml/2020/4/20/1800), and while GRUB2 EFI Loader support needs to happen with the kernel (https://lists.gnu.org/archive/html/grub-devel/2020-04/msg00203.html), GRUB2 already has RISC-V EFI support. It can't currently boot anything, but it is a valid UEFI application and displays a pretty menu.
Please see the attached debdiff. Of note:
* grub2 requires efibootmgr and efivar. I've filed Debian bugs to enable riscv64 for them (https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=959498 and https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=959499 respectively), but if this is actioned before those end up happening, it's a simple Architecture: update on each.
* riscv-default-platform.patch: Upstreamed, allows `grub-install` to work without --platform.
* riscv-relocation-offset.patch: Upstreamed: fixes "unaligned pointer" failure.
* riscv-ubuntu-linuxefi.patch: Patches ubuntu-linuxefi.patch for riscv support; not sure if this should be integrated into linuxefi.patch.
* Tested on qemu-system-riscv64 focal. |
