Validate with LLVM based toolchains as well.

Does this project support LLVM/Clang ?
I think the makefile and the /arch/riscv/build.mk does not support LLVM/Clang.

Send a pull request for flexible CROSS_COMPILE.

There should be only a commit, discarding unrelated ones. |
Already.
Sure. |
No, you didn't. This pull request should contain only your own commit(s) rather than the existing ones. |
You’re right — I did rebase onto the latest main, but I intentionally kept the existing upstream commits. I’ll drop or squash them shortly, thank again for pointing it out. |

Check https://cbea.ms/git-commit/ carefully and rework git commit messages.

That ci branch was my temporary testing branch.
I've updated the workflow so the CI runs on all branches by default.

May I know the reason why you download ubuntu-22.04 toolchain ?
Since your runner is ubuntu-24.04.

I noticed the same problem while working on LLVM support, so I temporarily included the updated setup-toolchain.sh with LLVM support in this PR.
Please have a look.
Introduce GitHub Actions-based CI that builds the kernel using the GNU RISC-V toolchain and runs selected apps (e.g., cpubench) in QEMU. Results are extracted and posted to PRs. Toolchain setup, build, and QEMU test logic are modularized into scripts in .ci/. Features: - Support multiple apps per run - CI comments results on PR automatically - Timeout prevents hangs Limitations: - Currently GNU-only (LLVM WIP) - cpubench doesn't exit cleanly due to preemptive mode Fixes: #2 Supersedes: sysprog21#11
Fixes #2
Improves upon PR: #11
This PR introduces a GitHub Actions CI workflow that:
