|
This driver allows other kernel drivers access to the
|
|
contents of the restricted access region control
|
|
registers.
|
|
|
|
The restricted access region control registers
|
|
(rar_registers) are used to pass address and
|
|
locking information on restricted access regions
|
|
to other drivers that use restricted access regions
|
|
|
|
The restricted access regions are regions of memory
|
|
on the Intel MID Platform that are not accessible to
|
|
the x86 processor, but are accessible to dedicated
|
|
processors on board peripheral devices.
|
|
|
|
The purpose of the restricted access regions is to
|
|
protect sensitive data from compromise by unauthorized
|
|
programs running on the x86 processor.
