[PATCH v2 2/7] scripts: python: Introduce thread sample processing to create thread

From: Anup Sharma
Date: Wed Jul 05 2023 - 15:44:56 EST


The _addThreadSample function is responsible for adding a sample to a specific
thread. It first checks if the thread exists in the thread_map dictionary.
If not, it creates a new thread using the _createtread function and assigns
it to the thread_map. Finally, it calls the 'addSample' method of the thread,
passing the thread name, stack, and timestamp.
