1*dcfbd31eSShravan Sconfig INTEL_SAR_INT1092 2*dcfbd31eSShravan S tristate "Intel Specific Absorption Rate Driver" 3*dcfbd31eSShravan S depends on ACPI 4*dcfbd31eSShravan S help 5*dcfbd31eSShravan S This driver helps to limit the exposure of human body to RF frequency by 6*dcfbd31eSShravan S providing information to userspace application that will inform the Intel 7*dcfbd31eSShravan S M.2 modem to regulate the RF power based on SAR data obtained from the 8*dcfbd31eSShravan S sensors captured in the BIOS. ACPI interface exposes this data from the BIOS 9*dcfbd31eSShravan S to SAR driver. The front end application in userspace will interact with SAR 10*dcfbd31eSShravan S driver to obtain information like the device mode, Antenna index, baseband index, 11*dcfbd31eSShravan S SAR table index and use available communication like MBIM interface to enable 12*dcfbd31eSShravan S data communication to modem for RF power regulation. Enable this config when 13*dcfbd31eSShravan S given platform needs to support "Dynamic SAR" configuration for a modem available 14*dcfbd31eSShravan S on the platform. 15
