cargo xflowey

To implement various developer workflows (both locally, as well as in CI), the OpenVMM project relies on flowey: a custom, in-house Rust library/framework for writing maintainable, cross-platform automation.

cargo xflowey is a cargo alias that makes it easy for developers to run flowey-based pipelines locally.

Some particularly notable pipelines:

  • cargo xflowey build-igvm - primarily dev-tool used to build OpenHCL IGVM files locally
  • cargo xflowey ci checkin-gates - runs the entire PR checkin suite locally
  • cargo xflowey restore-packages - restores external packages needed to compile and run OpenVMM / OpenHCL

xflowey vs xtask

In a nutshell:

  • cargo xtask: implements novel, standalone tools/utilities
  • cargo xflowey: orchestrates invoking a sequence of tools/utilities, without doing any non-trivial data processing itself
