Hi!
Is it possible to call a function that is somewere in the physical-address space? So I'd like to jump to a certain physical address, execute the code there and then return to my kernel module. I already tried to ioremap that address and cast the new address to a funtion pointer and then call the function, but there where some page faults.
Interesting, and after page fault....the code is still not executed? what code(s) do you call? user mode? kernel mode? -- regards, Mulyadi Santosa Freelance Linux trainer and consultant blog: the-hydra.blogspot.com training: mulyaditraining.blogspot.com
