1What: /sys/bus/platform/devices/INTC1092:00/intc_reg2Date: August 20213KernelVersion: 5.154Contact: Shravan S <s.shravan@intel.com>,5 An Sudhakar <sudhakar.an@intel.com>6Description:7 Specific Absorption Rate (SAR) regulatory mode is typically8 derived based on information like mcc (Mobile Country Code) and9 mnc (Mobile Network Code) that is available for the currently10 attached LTE network. A userspace application is required to set11 the current SAR regulatory mode on the Dynamic SAR driver using12 this sysfs node. Such an application can also read back using13 this sysfs node, the currently configured regulatory mode value14 from the Dynamic SAR driver.15 16 Acceptable regulatory modes are:17 == ====18 0 FCC19 1 CE20 2 ISED21 == ====22 23 - The regulatory mode value has one of the above values.24 - The default regulatory mode used in the driver is 0.25 26What: /sys/bus/platform/devices/INTC1092:00/intc_data27Date: August 202128KernelVersion: 5.1529Contact: Shravan S <s.shravan@intel.com>,30 An Sudhakar <sudhakar.an@intel.com>31Description:32 This sysfs entry is used to retrieve Dynamic SAR information33 emitted/maintained by a BIOS that supports Dynamic SAR.34 35 The retrieved information is in the order given below:36 - device_mode37 - bandtable_index38 - antennatable_index39 - sartable_index40 41 The above information is sent as integer values separated42 by a single space. This information can then be pushed to a43 WWAN modem that uses this to control the transmit signal44 level using the Band/Antenna/SAR table index information.45 These parameters are derived/decided by aggregating46 device-mode like laptop/tablet/clamshell etc. and the47 proximity-sensor data available to the embedded controller on48 given host. The regulatory mode configured on Dynamic SAR49 driver also influences these values.50 51 The userspace applications can poll for changes to this file52 using POLLPRI event on file-descriptor (fd) obtained by opening53 this sysfs entry. Application can then read this information from54 the sysfs node and consume the given information.55
