CONFIG_RPMSG_WWAN_CTRL: RPMSG WWAN control driver

General informations

The Linux kernel configuration item CONFIG_RPMSG_WWAN_CTRL:

Help text

RPMSG WWAN CTRL allows modems available via RPMSG channels to expose different modem protocols/ports to userspace, including AT and QMI. These protocols can be accessed directly from userspace (e.g. AT commands) or via libraries/tools (e.g. libqmi, libqcdm...).

This is mainly used for modems integrated into many Qualcomm SoCs, e.g. for AT and QMI on Qualcomm MSM8916 or MSM8974. Note that many newer Qualcomm SoCs (e.g. SDM845) still provide an AT port through this driver but the QMI messages can only be sent through QRTR network sockets (QRTR).

To compile this driver as a module, choose M here: the module will be called rpmsg_wwan_ctrl.
