help
|
||||
If this option is disabled, you allow userspace (root) access to all
|
||||
of memory, including kernel and userspace memory. Accidental
|
||||
access to this is obviously disastrous, but specific access can
|
||||
be used by people debugging the kernel.
|
||||
|
||||
If this option is switched on, the /dev/mem file only allows
|
||||
userspace access to memory mapped peripherals.
|
||||
|
||||
If in doubt, say Y.
