@hungry-foolish hey, this is too huge to review and I believe most of it is FreeRTOS code which doesn't need a review. Pointers in the commit description to the files/functions you changed from FreeRTOS or what you added will help in the review.

@phanikishoreg is right. I can't even find your changes.

Please do a separate PR with just your changes, and composite-specific stuff. Keep this PR around so that we can refer to the broader code here.
