I have a kernel extension (which is not an IOKit driver) that uses OSMalloc_ KPI to allocate buffer. I pass in OSMT_DEFAULT so that buffers that it returns are wired to memory. I have a use case where in I would like to get physical address of the first byte of the buffer. I understand that buffer will not be contiguous in Physical memory and I am fine with that. Do we have such an interface --- something like: physAddr = virt_to_phys(buffer); // Gives physical address of first byte of the buffer -- Shailesh Jain _______________________________________________ Do not post admin requests to the list.
