Hi,
Here's a group of patches to the tee subsystem with cleanups and not so urgent fixes related to tee shared memory.
- Unused parts of the shared memory object (struct tee_shm) are removed.
- Shared memory ids usable from user space are not assigned to driver private shared memory objects
- The TEE_SHM_USER_MAPPED is used instead of TEE_SHM_REGISTER to accurately tell if a shared memory object originates from another user space mapping.
Only unused "features" should be removed with this patch set, there should be no change in behaviour or breakage with other code.
I'll pick up these as they are in a few days if there's no further comments.
Thanks, Jens
Thanks, Jens
