[PATCH v2 0/1] tee: Add tee_shm_register_fd

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Add a new ioctl called TEE_IOC_SHM_REGISTER_FD to register a
shared memory from a dmabuf file descriptor.
This new ioctl will allow the Linux Kernel to register a buffer
to be used by the Secure Data Path OPTEE OS feature.
