This work item:
- Aims to add the riscv64 riscv64gc-unknown-linux-gnu Rust Language target triplet to the Rust Language github CI runner infrastructure.
- Aims to use the same target platform and target root filesystem file-system assets as used in LR_07_001.
- Aims to use an experimental branch in the upstream CI runner infrastructure. This is expected to be the case until Tier-1 attainment.
Upon successful implementation, the riscv64 riscv64gc-unknown-linux-gnu Rust Language target triplet will automatically get tested upon every commit to the Rust Language github repository's main branch. This essentially paves the way for Tier-1 attainment.Enablement PR: https://github.com/rust-lang/rust/pull/126641
Updates
- Here's the PR tracking the CI loop enablement.
- While exploring
...
- options, a remote test variant was chosen. This limits testing to "target" support, and skips "host tools" support.
...
- This is because using Rust's normal testing infrastructure (Docker), the test suite required for a "Tier 1 with Host Tools" test is significantly over 6 hours, even on quite powerful hardware.
- The Dockerfile tested is located
...
- here.
- According to the Target Tier
...
...
- , such long test times alone are enough to disqualify a target from reaching Tier 1.
- In the
...
- interim, we are pursuing "Tier 1 (without host tools)"
...
- .
- This will ensure that the target tests (aka the functionality of
...
- artefacts produced by the x86_64 platform to be executed on the riscv64gc platform) would pass, without requiring the tools to be passing.
- Alongside that work, we are pursuing successful (and fast) full host test suite runs in partnership with
