The task collects data from available sensors and report them to AP. Besides the task reports the sensor data to AP. Based on the data, it also does other things like calculating lid angle and detect tablet mode. config PLATFORM_EC_ACCEL_FIFO bool "Sensor FIFO" help Enable this to add the sensor FIFO used by sensor device drivers to fill. Using FIFO reduces power consumption since it reduces the number of AP wake-ups. if PLATFORM_EC_ACCEL_FIFO config PLATFORM_EC_ACCEL_FIFO_SIZE int "Motion Sense FIFO Size" default 256 help This sets the size of the sensor FIFO, must be a power of 2. config PLATFORM_EC_ACCEL_FIFO_THRES int "FIFO Threshold" default 85 # (PLATFORM_EC_ACCEL_FIFO_SIZE / 3) help This sets the amount of free entries that trigger an interrupt to the AP. endif # PLATFORM_EC_ACCEL_FIFO config PLATFORM_EC_SENSOR_TIGHT_TIMESTAMPS bool "Extra Sensor Timestamp" help If this is defined, motion_sense sends sensor events to the AP in the format +-----------+ | Timestamp | | Payload | | Timestamp | | Payload | | ... | +-----------+ If this is not defined, the events will be sent in the format +-----------+ | Payload | | Payload | | Payload | | ... | | Timestamp | +-----------+ The former format enables improved filtering of sensor event timestamps on the AP, but comes with stricter jitter requirements. # TODO(b/173507858) config PLATFORM_EC_MOTION_FILL_LPC_SENSE_DATA # if PLATFORM_EC_MOTION_FILL_LPC_SENSE_DATA #endif # PLATFORM_EC_MOTION_FILL_LPC_SENSE_DATA config PLATFORM_EC_MAX_SENSOR_FREQ_MILLIHZ int "Maximal EC sampling rate" default 250000 help Lower this limit for slower EC (in mHz). config PLATFORM_EC_ALS bool "Ambient Light Sensor(ALS)" help Enable this to indicate there's at least one or more ALS devices available. If PLATFORM_EC_MOTION_FILL_LPC_SENSE_DATA is set, then motion task updates the designated part of EC memmap with the ALS data. The updating EC memmap can be also done by the dedicated ALS task with HAS_ALS_TASK set. Number of ALS entries reserved in EC memmap are defined by EC_ALS_ENTRIES in ec_commands.h. config PLATFORM_EC_DYNAMIC_MOTION_SENSOR_COUNT bool "Dynamic Motion Sensor Count" help Enable this to allow changing motion sensor count dynamically. config PLATFORM_EC_LID_ANGLE bool "Lid Angle" select PLATFORM_EC_MATH_UTIL help Enable this to detect lid angle with two accelerometers. The andgle calculation requires the information about which sensor is on the lid and which one is on the base. The measured lid angle can be used for tablet mode detection(refer "Tablet Mode below") and enabling/disabling peripheral devices(refer "Lid Angle Update" below). # TODO(b/173507858): add more detail after .dts change if PLATFORM_EC_LID_ANGLE config PLATFORM_EC_LID_ANGLE_UPDATE bool "Lid Angle Update" help Enable this to allow using the lid angle measurement to determine if peripheral devices should be enabled or disabled, like key scanning, trackpad interrupt. config PLATFORM_EC_TABLET_MODE bool "Tablet Mode" help Enable this for a device which can be a tablet as well as a clamshell. Tablet mode detection is done either by using the lid angle measurement or by the dedicated GMR sensor. if PLATFORM_EC_TABLET_MODE config PLATFORM_EC_TABLET_MODE_SWITCH bool "Tablet Mode Switch" depends on PLATFORM_EC_MKBP_INPUT_DEVICES help Enable a virtual switch to indicate when we are in tablet mode. The tablet mode state is sent to AP via MKBP protocol(switch event). config PLATFORM_EC_GMR_TABLET_MODE bool "Giant Magnetoresistance(GMR) Tablet Mode" help Enable this to use GMR sensor to detect tablet mode. It requires to set GPIO_TABLET_MODE_L to map the interrupt from the sensor and direct its mapping to gmr_tablet_switch_isr in common/tablet_mode.c. endif # PLATFORM_EC_TABLET_MODE endif # PLATFORM_EC_LID_ANGLE config PLATFORM_EC_CONSOLE_CMD_ACCELS bool "Console commands: accels, accelrate, accelinit, accelinfo, etc." help Enables console commands: accelrange - Read or write accelerometer range accelres - Read or write accelerometer resolution accelrate - Read or write accelerometer ODR accelread [n(iteration)] - Read sensor x/y/z accelinit - Init sensor if PLATFORM_EC_CONSOLE_CMD_ACCELS config PLATFORM_EC_CONSOLE_CMD_ACCEL_INFO bool "Console Command: accelinfo" help Enable console command: accelinfo on/off [interval] - Print motion sensor info, lid angle calculations and set calculation frequency. endif # PLATFORM_EC_CONSOLE_CMD_ACCELS config PLATFORM_EC_ACCEL_SPOOF_MODE bool "Sensor spoof mode" help Enable this to allow sensors values spoofed to any arbitrary value. This is useful for testing the motion sense framework if the hardware sensor or the sensor driver code is not ready. if PLATFORM_EC_ACCEL_SPOOF_MODE config PLATFORM_EC_CONSOLE_CMD_ACCEL_SPOOF bool "Console Command: accelspoof" help Enable console command: accelspoof id [on/off] [X] [Y] [Z] - Enable/Disable spoofing of sensor readings. endif # PLATFORM_EC_ACCEL_SPOOF_MODE rsource "Kconfig.sensor_devices"
