XTOS components, target architectures, workflow, and validation scope.

Build x86_64 on a Linux host, then boot and self-test with QEMU.

Kernel, user-space, SDK, and application responsibilities; BCI and CSV data paths.

Directory roles, configuration files, build artifacts, and guest paths.

Dependencies, parameters, configuration, and artifacts for x86_64, ARM64, and RISC-V64.

Boot with QEMU, run self-tests, and inspect logs.

Check XTOS with host builds, QEMU guests, and explicit markers.

Builds, linking, data formats, and call order for three C libraries.

Linux scheduling, affinity, locked memory, and single-producer single-consumer frame queues.

Timestamps, DFT power, filter state, and SSVEP/P300 features.

BCI sessions, device capability, buffer ownership, and released data-format limits.

Three complete C examples: an RT queue, synthetic signal processing, and a BCI session.

Use symptoms, check results, and repair paths for build, guest, and BCI failures.

Create a branch, change source, run checks, and submit a pull request.
