Im sorry that my there were something wrong about my notebook for a half of month. Here, I want to use system shared memory API to share data across processes, but I want it use a specified range of memory knowned by a slave core such as DSP, etc. If I can do? thanks.

As the topic, I want to specify a fixed physical memory space to a shared memory object, which can use shm_XXX api to access the memory. Of course I do not want to use mmap api to map /dev/mem device memory into user program. Step back and tell us exactly what problem you have, that you have come up to this type of solution being necessary? What do you think you can solve by doing this?
thanks,
