Hi, I have two independent processors with access to a shared memory region, mapped in the 256MB to 512MB region (kseg0). One is running a propietary OS, and the second one is running Linux 2.6.12. How would I arrange to leave that shared memory region out of the scope of Linux's memory management system, but at the same time make it possible for a driver to access it? I have done similar things before with the help of alloc_bootmem, but this time I don't want the kernel to reserve the memory, I want the kernel to be completely unaware of it, and I need to specify its start and end. Any idea very much welcomed, thanks Alex
