# # RAR device configuration # menu "RAR Register Driver" # # Restricted Access Register Manager # config RAR_REGISTER tristate "Restricted Access Region Register Driver" depends on PCI default n ---help--- 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. endmenu
