RISC-V port upstream planning

Setting aside this ticket to manage plans for upstreaming my RISC-V port of Alpine Linux.

Links

• WIP aports tree
• riscv64 package repository (signing key)

The package repository is entirely natively built. I have a separate repository for the cross-compiled bootstrap packages, but I am working on rebuilding everything natively.

Pulls

• abuild!76 (closed)
• !16361 (merged)

Testing the port

qemu

TODO: Blocked on kernel & u-boot packages

HiFive Unleashed

TODO: Blocked on kernel & u-boot packages

HiFive Unmatched

TODO: Hardware on order

Blockers

1. Natively build the bootstrap packages.
2. Rebase and address porting issues, see FIXME and DROPME commits.
3. Prepare aports pulls upstreaming riscv64 fixes.
4. u-boot and kernel packages, initramfs.
5. Write release scripts and produce a convenient install package.
6. Set up a builder? Finish building main & community, address issues as they come?

I have a RISC-V board which I am willing to devote to Alpine's use, for devs to have shell access to and as a builder.

Comments

• The gcc cross compiler built by bootstrap.sh will likely have issues with libatomic for anyone who tries to use it, especially for building LLVM. It should work if you use the hosted build.
