Logical, Linear and Virtual Address.

[Gustavo da Silva]

Hi Everyone!

Friends, could someone explain me the difference between Kernel Logical
and Kernel Virtual Address?

I'm reading Linux Device Drivers 3th, but I did not understand about that.

I have a macro vision about Kernel Virtual Address (virtual address is used
do hide the paging mechanism and physical memory, I think), and Linear
is the address used in to evaluate to the physical (using page
directory+page table+offset).

But and the Kernel Logical Address? Why Logical Address is Virtual
Address, but not all
Virtual Address is a Logical Address?

Regards.

Atenciosamente,
