Detailed Description

Arguments for a UK call are stored in a structure. This structure consists of a fixed size header and a payload. The header carries a 32-bit number identifying the UK function to be called (see uk_func). When the UKK client receives this header and executed the requested UK function, it will use the same header to store the result of the function in the form of a int return code. The size of this structure is such that the first member of the payload following the header can be accessed efficiently on a 32 and 64-bit kernel and the structure has the same size regardless of a 32 or 64-bit kernel. The uk_kernel_size_type type should be defined accordingly in the OS specific mali_uk_os.h header file.
