Subject: [PATCH 00/14] net: wwan: t7xx: PCIe driver for MediaTek M.2 modem
Date: Thu, 21 Oct 2021 13:27:24 -0700 [thread overview]
Message-ID: <20211021202738.729-1-ricardo.martinez@linux.intel.com> (raw)
t7xx is the PCIe host device driver for Intel 5G 5000 M.2 solution which is based on MediaTek's T700 modem to provide WWAN connectivity.
The driver uses the WWAN framework infrastructure to create the following control ports and network interfaces:
* /dev/wwan0mbim0 - Interface conforming to the MBIM protocol. Applications like libmbim [1] or Modem Manager [2] from v1.16 onwards with [3][4] can use it to enable data communication towards WWAN.
* /dev/wwan0at0 - Interface that supports AT commands.
* wwan0 - Primary network interface for IP traffic.
The main blocks in t7xx driver are:
* PCIe layer - Implements driver probe, removal, and power management callbacks.
* Port-proxy - Provides a common interface to interact with different types of ports such as WWAN ports.
* Modem control & status monitor - Implement the entry point for modem initialization, reset and exit, as well as exception handling.
* CLDMA (Control Layer DMA) - Manages the HW used by the port layer to send control messages to the modem using MediaTek's CCCI (Cross-Core Communication Interface) protocol.
* DPMAIF (Data Plane Modem AP Interface) - Controls the HW that provides uplink and downlink queues for the data path. The data exchange takes place using circular buffers to share data buffer addresses and metadata to describe the packets.
* MHCCIF (Modem Host Cross-Core Interface) - Provides interrupt channels for bidirectional event notification such as handshake, exception, PM and port enumeration.
The compilation of the t7xx driver is enabled by the CONFIG_MTK_T7XX config option which depends on CONFIG_WWAN.
This driver was originally developed by MediaTek. Intel adapted t7xx to the WWAN framework, optimized and refactored the driver source in close collaboration with MediaTek. This will enable getting the t7xx driver on Approved Vendor List for interested OEM's and ODM's productization plans with Intel 5G 5000 M.2 solution.
