A good idea to get there is to use vmem_map, which allows have a discontiguous mem_map array in virtual storage. Then add the memory segment's address range to it. Sparsemem also helps, if vmem_map is not available. Second, implement get_xip_page for this file system. This address space operation needs to be provided for all files that are supposed to be XIP. readpage(s)/writepage(s) should not be provided for these files, becuase they rely on using the page cache. Third, use file operations from mm/filemap_xip.c. so long, Carsten - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
