AMD RPU FreeRTOS System Port

This directory contains the OS glue that lets the remote IRQ shared-memory demo run as a FreeRTOS task on the AMD RPU.

• main.c creates the worker task and drives the FreeRTOS scheduler.

• gic_init.c installs the IPI ISR using the FreeRTOS interrupt helpers.

• amp_demo_os.h records the demo task handle so system_suspend() can call vTaskSuspend(NULL) while system_resume() wakes it with xTaskResumeFromISR, allowing the Idle task to run while the demo waits for a kick.

The top-level machine README covers configuration flags and build steps. When PROJECT_SYSTEM=freertos, CMake automatically pulls in the sources from this directory.
