Meeting Summary

Ocre Project Update

• Ocre infrastructure is maturing with GitHub best practices implemented, including code owners, security measures, and workflow actions.

• Ocre tooling

  • Refreshed Ocre C/C++ container with updates to the WASI SDK and GCC versions.

  • Plans to integrate an Ocre CLI into the C\C++ dev container soon to enable users to upload/manage containers via a 3rd-party registry.

  • Plans to add additional Zephyr subshell commands to the Ocre runtime to ease container management (e.g., load, unload, etc.).

General Discussion

• Discussed support for Linux as a target platform, particularly for resource-constrained devices with 4-8MB RAM where Docker isn't viable.

• Explored testing infrastructure needs and simulation capabilities for hardware testing.

• Dan raised questions about Execute-In-Place (XIP) support for core runtime and containers, with Stephen noting the current Ocre runtime supports it, but WAMR implementation needs work. Solutions discussed: optional filesystems, contiguous layout filesystems, or buffer bank management.

• Discussed Zephyr 4.0 release, and versioning strategy — confirming commitment to v3.7 LTS for the near future.

• Established a need for a formal process to gather agenda items before meetings.
