8.1. Deprecated Normal-World Hypervisor

Warning

The following pages describe Hafnium’s legacy normal-world hypervisor. This implementation is retained only as historical reference and test infrastructure. It is not a supported product target, and current Hafnium documentation should be read as SPMC-first.

Relevant maintained guidance lives in:

• Prerequisites for toolchain and FVP setup.

• Building for supported build flows.

• Hafnium Tests for current test execution.

• Project Structure for the current source tree.

These pages are kept because some tests, drivers, overlays, and FF-A compatibility paths still rely on the legacy hypervisor code. Treat the content below as deprecated reference material, not current guidance.
