[Lima] How to monitoring memory usage in lima?

[Qiang Yu]

You mean you can't find the memory management code in lima kernel
driver? Lima just uses code from drm_gem_shmem_helper.c for MM.

I've reviewed the Lima driver, but it doesn't seem to be able to get the memory being used at the driver level like the mali-400 driver. I wonder if I haven't found it or if there is no other way.
