Current ION free memory

How may I determine current usage of ION memory?

How ION memory is used by CVI_TDL_OpenModel exactly? How much it allocates ION memory, needs pools, and why?

This is a companion discussion topic for the original entry at

/sys/kernel/debug/ion/cvi_carveout_heap_dump/summary seems to show ion memory state

Thank you @zzz197!

Unfortunately on Duo 64 I get:

[root@milkv-duo]~# cat /sys/kernel/debug/ion/cvi_carveout_heap_dump/summary
cat: /sys/kernel/debug/ion/cvi_carveout_heap_dump/summary: No such file or directory
