7 Intel Processor common Overclocking Watchdog support
9 config SOC_INTEL_COMMON_OC_WDT_ENABLE
10 bool "Enable overclocking watchdog during boot"
11 depends on SOC_INTEL_COMMON_BLOCK_OC_WDT
13 Enables Intel chipset Overclocking Watchdog to count during system
14 boot. The platform will reset during lockups if watchdog is not
15 reloaded. Software/firmware is responsible for feeding the watchdog.
19 config SOC_INTEL_COMMON_OC_WDT_TIMEOUT_SECONDS
21 depends on SOC_INTEL_COMMON_OC_WDT_ENABLE
25 The Intel chipset Overclocking Watchdog timeout value in seconds.
26 coreboot will preload the watchdog with the timeout value specified
27 in this option. Specify a high enough value so that the platform
28 will have a chance to perform full memory training and boot. Default
29 is 10 minutes. Boards and SoCs may override this value.
31 config SOC_INTEL_COMMON_OC_WDT_RELOAD_IN_PERIODIC_SMI
32 bool "Reload the overclocking watchdog using periodic SMI"
33 depends on SOC_INTEL_COMMON_OC_WDT_ENABLE
34 depends on SOC_INTEL_COMMON_BLOCK_SMM
37 Enables Intel chipset Overclocking Watchdog reloading in the periodic
38 SMI handler. Without this option the platform will keep power cycling
39 unless the OS drivers are installed for this watchdog.
