Yes, you can now access the RAM above 40MB with ioremap ..... what do you mean by good memory regoin ? > Does somebody know the good method to reserve large memory region ? > I'm using 2.6 kernel. As you already reserved the RAM above 40MB through mem=40M option, now you can use it freely through ioremap and you can consider this region as usable regoing for you ...... You have to use ioremap to map memory in chunks, map a chunk of memory let say 4KB (a page) use it, unmap it and then map other 4KB and so on ....... then you can access whole memory above 40M or your reserved memory. -- Fawad Lateef -- Kernelnewbies: Help each other learn about the Linux kernel.
