This information is only useful for kernel developers 12 who are working in architecture specific areas of the kernel. 13 It is probably not a good idea to enable this feature in a production 14 kernel. 15 If in doubt, say "N" 16 17config STRICT_DEVMEM 18 bool "Filter access to /dev/mem" 19 depends on MMU 20 ---help--- 21 If this option is disabled, you allow userspace (root) access to all 22 of memory, including kernel and userspace memory.

Say Y here only if you 1600 are planning to use hardware trace tools with this kernel. 1601 1602config DEBUG_SET_MODULE_RONX 1603 bool "Set loadable kernel module data as NX and text as RO" 1604 depends on MODULES 1605 ---help--- 1606 This option helps catch unintended modifications to loadable 1607 kernel module's text and read-only data. It also prevents execution 1608 of module data. Such protection may interfere with run-time code 1609 patching and dynamic kernel tracing - and they might also protect 1610 against certain classes of kernel exploits. 1611 If in doubt, say "N". 1612 1613menuconfig CORESIGHT 1614 bool "CoreSight Tracing Support" 1615 select ARM_AMBA 1616 help 1617 This framework provides a kernel interface for the CoreSight debug 1618 and trace drivers to register themselves with.
