Hello,
I am having some difficulty mapping memory in my rtlinux module. I am
attempting
to map the memory on the vga card which is at physical address 0xe2000000.
To
attempt to do the mapping I call mmap after opening /dev/mem. Everything
works
find and no errors are returned. Once I try to use the pointer returned by
mmap I get the following error:
Unable to handle kernel paging request at virtual address e200000.
Any ideas what the problem is?
Thanks
Adam
