So to get started with the IOCTL's needed between TEE clients in user space and the generic driver. Have the different use cases in back of your mind when thinking about this.

Here are three IOC's needed. What else?

IOCTL's: TEE_IOC_CMD TEE_IOC_SHM_ALLOC TEE_IOC_SHM_FREE

I would also like to add something like TEE_IOC_MEM_MAP TEE_IOC_MEM_UNMAP

They would be use in the case of creating a mapping of a pointer from the CA. Something like creating a scatter list for some random memory inside the calling CA.
