Hello TWG - pat, mark & steve.
I've seen your post to linuxppc-embedded@lists.linuxppc.org regarding
memory access from Linux.
Your code works fine.
"paddr2 = mmap(0,size,PROT_READ|PROT_WRITE,MAP_SHARED,fd,0x50000000);"
But page size is 1K and their start addresses appears in address
space with increment 0x1000.
So if I put 0x50000400 address it give me segmentation fault. It works
fine in region 0x50000000 ... 0x500003ff next 0x50001000 ...
0x500103ff and so on.
Question : how can we increase page size to eliminate these holes.
Thanks in advance.
