Whipers' medium model: Cannot allocate memory

[brunocaballero]

Hi,

I was experimenting with this project and tried to use the whisper's "medium" model.

It fails allocating memory on one of the rknn_create_mem after alllocating around 2GB of memory.

Did I hit some limit?

Do you think is there a way to support bigger models?

This is the output of strace: rknn_create_mem issues some DRM_IOCTL and the perform a mmap.
