This option alone does not add any kernel code. If you say N, all options in this submenu will be skipped and disabled. if [31mCONFIG_CHROME_PLATFORMS[0m config [31mCONFIG_CHROMEOS_LAPTOP[0m tristate "Chrome OS Laptop" depends on [31mCONFIG_I2C[0m && [31mCONFIG_DMI[0m && [31mCONFIG_X86[0m ---help--- This driver instantiates i2c and smbus devices such as light sensors and touchpads. If you have a supported Chromebook, choose Y or [31mCONFIG_M[0m here. The module will be called chromeos_laptop. config [31mCONFIG_CHROMEOS_PSTORE[0m tristate "Chrome OS pstore support" depends on [31mCONFIG_X86[0m ---help--- This module instantiates the persistent storage on x86 ChromeOS devices. It can be used to store away console logs and crash information across reboots. The range of memory used is 0xf00000-0x1000000, traditionally the memory used to back VGA controller memory. If you have a supported Chromebook, choose Y or [31mCONFIG_M[0m here. The module will be called chromeos_pstore. config [31mCONFIG_CROS_EC_CHARDEV[0m tristate "Chrome OS Embedded Controller userspace device interface" depends on [31mCONFIG_MFD_CROS_EC[0m ---help--- This driver adds support to talk with the ChromeOS EC from userspace. If you have a supported Chromebook, choose Y or [31mCONFIG_M[0m here.

This uses a simple byte-level protocol with a checksum. This is used for userspace access only. The kernel typically has its own communication methods. To compile this driver as a module, choose [31mCONFIG_M[0m here: the module will be called cros_ec_lpc. config [31mCONFIG_CROS_EC_PROTO[0m bool help ChromeOS EC communication protocol helpers. config [31mCONFIG_CROS_KBD_LED_BACKLIGHT[0m tristate "Backlight LED support for Chrome OS keyboards" depends on [31mCONFIG_LEDS_CLASS[0m && [31mCONFIG_ACPI[0m help This option enables support for the keyboard backlight LEDs on select Chrome OS systems.
