# TODO(b/177676794): Add the CONFIG_THROTTLE_AP_ON_... options
config PLATFORM_EC_CHIPSET_CAN_THROTTLE
bool "CPU can support throttling"
default y
help
Indicates that the SoC supports throttling. This means that a
chipset_throttle_cpu() function is provided by the chipset, to be
called to set the throttle state. The typical implementation asserts
GPIO_CPU_PROCHOT, to make the CPU slow down.
config PLATFORM_EC_CONSOLE_CMD_APTHROTTLE
bool "Console command: apthrottle"
default y
help
This command shows the current status of AP throttling. Both soft
(type 0) and hard (type 1) throttling are supported. Soft throttling
is typically controlled by the AP via a host event. Hard throttling
typically uses the PROCHOT (Processor Hot) signal on x86 CPUs.
Example output:
AP throttling type 0 is off (0x00000000)
AP throttling type 1 is off (0x00000000)
