I have a question: is there any reference in regards to how / when to use
the virt_to_phys, virt_to_bus, ioremap, etc. ... functions, other than
/usr/src/linux/Documentation/IO-mapping.txt ?!? I'd like to understand it
better, but this text has not been enough (for me, of course).
If there is no other way, I'll try to re-read it 1000 times to see if my
understanding increases 1000 times as well ... ;)
Thanks in advance for any help !!
Regards,
Ivan Passos
