In linux kernel since version 5.2 (release Date: 2019-07-07)
This driver helps to limit the exposure of human body to RF frequency by
providing information to userspace application that will inform the Intel
M.2 modem to regulate the RF power based on SAR data obtained from the
sensors captured in the BIOS. ACPI interface exposes this data from the BIOS
to SAR driver. The front end application in userspace will interact with SAR
driver to obtain information like the device mode, Antenna index, baseband index,
SAR table index and use available communication like MBIM interface to enable
data communication to modem for RF power regulation. Enable this config when
given platform needs to support "Dynamic SAR" configuration for a modem available
on the platform.
