11 help
12 Say Y here if you want to use the WWAN driver core. This driver
13 provides a common framework for WWAN drivers.

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

27 If this option is selected, then you can find the debug interface
28 elements for each WWAN device in a directory that is corresponding to
29 the device name: debugfs/wwan/wwanX.

43 help
44 MHI WWAN CTRL allows QCOM-based PCIe modems to expose different modem
45 control protocols/ports to userspace, including AT, MBIM, QMI, DIAG
46 and FIREHOSE. These protocols can be accessed directly from userspace
47 (e.g. AT commands) or via libraries/tools (e.g. libmbim, libqmi,
48 libqcdm...).

56 help
57 MHI WWAN MBIM is a WWAN network driver for QCOM-based PCIe modems.
58 It implements MBIM over MHI, for IP data aggregation and muxing.
59 A default wwan0 network interface is created for MBIM data session
60 ID 0. Additional links can be created via wwan rtnetlink type.

68 help
69 The BAM Data Multiplexer provides access to the network data channels
70 of modems integrated into many older Qualcomm SoCs, e.g. Qualcomm
71 MSM8916 or MSM8974. The connection can be established via QMI/AT from
72 userspace with control ports available through the WWAN subsystem
73 (CONFIG_RPMSG_WWAN_CTRL) or QRTR network sockets (CONFIG_QRTR).

80 depends on RPMSG
81 help
82 RPMSG WWAN CTRL allows modems available via RPMSG channels to expose
83 different modem protocols/ports to userspace, including AT and QMI.
84 These protocols can be accessed directly from userspace
85 (e.g. AT commands) or via libraries/tools (e.g. libqmi, libqcdm...).
86
87 This is mainly used for modems integrated into many Qualcomm SoCs,
88 e.g. for AT and QMI on Qualcomm MSM8916 or MSM8974. Note that many
89 newer Qualcomm SoCs (e.g. SDM845) still provide an AT port through
90 this driver but the QMI messages can only be sent through
91 QRTR network sockets (CONFIG_QRTR).
