🔵 Needs a closer look
The IPC backend and cavstool harness are outside the snapshot, so endpoint contracts, acknowledgement handling, and the revised DMA drain condition require validation on Intel ADSP hardware.
No open issues 🎉
What changed in this PR
Converts the userspace Intel HDA DMA test to use Zephyr’s IPC service for communication with the cavstool host.
Changes:
- Replaces direct IPC handlers with endpoint registration, messaging, and cleanup.
- Adds explicit waits for host acknowledgments and validation results.
- Updates DMA completion polling to wait until no data remains pending.
