This driver enables Thunderbolt Networking on non-Apple platforms running Linux. Thunderbolt Networking provides peer-to-peer connections to transfer files between computers, perform PC migrations, and/or set up small workgroups with shared storage. This is a virtual connection that emulates an Ethernet adapter that enables Ethernet networking with the benefit of Thunderbolt superfast medium capability. Thunderbolt Networking enables two hosts and several devices that have a Thunderbolt controller to be connected together in a linear (Daisy chain) series from a single port. Thunderbolt Networking for Linux is compatible with Thunderbolt Networking on systems running macOS or Windows and also supports Thunderbolt generation 2 and 3 controllers. Note that all pre-existing Thunderbolt generation 3 features, such as USB, Display and other Thunderbolt device connectivity will continue to function exactly as they did prior to enabling Thunderbolt Networking. Code and Software Specifications: This kernel code creates a virtual ethernet device for computer to computer communication over a Thunderbolt cable. The new driver is a separate driver to the existing Thunderbolt driver. It is designed to work on systems running Linux that interface with Intel Connection Manager (ICM) firmware based Thunderbolt controllers that support Thunderbolt Networking. The kernel code operates in coordination with the Thunderbolt user- space daemon to implement full Thunderbolt networking functionality. Hardware Specifications: Thunderbolt Hardware specs have not yet been published but are used where necessary for register definitions. Changes since v6: - Removed (TM) from Kconfig - Removed redundant DRV_NAME macro - Removed copyright notice from Makefile - Moved networking.txt file to Documentation/Thunderbolt/ - Edited patch descriptions - Edited documentation in networking.txt These patches were pushed to GitHub where they can be reviewed more comfortably with green/red highlighting: https://github.com/01org/thunderbolt-software-kernel-tree Daemon code: https://github.com/01org/thunderbolt-software-daemon For reference, here's a link to version 6: [v6]: https://lkml.org/lkml/2016/8/1/233 Amir Levy (8): thunderbolt: Macro rename thunderbolt: Updating the register definitions thunderbolt: Kconfig for Thunderbolt Networking thunderbolt: Communication with the ICM (firmware) thunderbolt: Networking state machine thunderbolt: Networking transmit and receive thunderbolt: Networking doc thunderbolt: Adding maintainer entry Documentation/00-INDEX | 2 + Documentation/thunderbolt/networking.txt | 132 ++ MAINTAINERS | 8 +- drivers/thunderbolt/Kconfig | 27 +- drivers/thunderbolt/Makefile | 3 +- drivers/thunderbolt/icm/Makefile | 2 + drivers/thunderbolt/icm/icm_nhi.c | 1622 +++++++++++++++++++++ drivers/thunderbolt/icm/icm_nhi.h | 92 ++ drivers/thunderbolt/icm/net.c | 2264 ++++++++++++++++++++++++++++++ drivers/thunderbolt/icm/net.h | 297 ++++ drivers/thunderbolt/nhi_regs.h | 115 +- 11 files changed, 4555 insertions(+), 9 deletions(-) create mode 100644 Documentation/thunderbolt/networking.txt create mode 100644 drivers/thunderbolt/icm/Makefile create mode 100644 drivers/thunderbolt/icm/icm_nhi.c create mode 100644 drivers/thunderbolt/icm/icm_nhi.h create mode 100644 drivers/thunderbolt/icm/net.c create mode 100644 drivers/thunderbolt/icm/net.h -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
