The sizes recorded are as follows: - Per group: suspend buffer, protm-suspend buffer, syncobjcs - Per queue: ringbuffer, profiling slots, firmware interface - For all heaps in all heap pools across all VM's bound to an open file, record size of all heap chuks, and for each pool the gpu_context BO too. This does not record the size of FW regions, as these aren't bound to a specific open file and remain active through the whole life of the driver.
