How I can map some physical memory region to task address space? I tried to use l4sigma0_map_mem, but it return me "No fpage received" error. I tried different region szes from 256M to 4K.
A normal program cannot get any memory from sigma0 anymore as moe has taken everything. So you need to get a memory dataspace from moe. For that dataspace you can also query the physical address of the backing memory (you need to allocate it pinned for that).
