[PATCH 0/3] Add the Generic Netlink controller

by Alexandre Bailon

Currently, only the es2 hd controller is supported, which restrict the usage of greybus to few products. This series intents to add a support of new hd controllers. The driver doesn't support any hardware. Actually, the controller is just a bridge between Greybus kernel and userspace. The real driver must be implemented in userspace. This give the ability to support any kind of transport layer (such as Bluetooth, WiFi, Ethernet). The controller uses Generic Netlink. My original intent was to implement a TCP/IP controller but it was very slow, unstable. In addition, some features such as SVC or module discovery were to add to implement in kernel side. With the generic netlink controller, we can easily add support of new controller. It also helps to deal with all the project ARA legacy such as SVC. I have started to implement an application which is able to emulate the SVC, a module (like gbsim but only support control and loopback protcols), TCP/IP, Bluetooth and UART. It is still under development but it was stable enough to test this series. The application can found here: https://github.com/anobli/gbridge Alexandre Bailon (3): staging greybus: make cport_quiesce() method optional staging: greybus: Add Greybus netlink driver staging: greybus: netlink: Add a way to "hot remove" SVC drivers/staging/greybus/Kconfig | 9 ++ drivers/staging/greybus/Makefile | 2 + drivers/staging/greybus/connection.c | 3 + drivers/staging/greybus/gb_netlink.h | 38 ++++++ drivers/staging/greybus/netlink.c | 256 +++++++++++++++++++++++++++++++++++ 5 files changed, 308 insertions(+) create mode 100644 drivers/staging/greybus/gb_netlink.h create mode 100644 drivers/staging/greybus/netlink.c -- 2.10.2

greybus file names

by Tobin C. Harding

Is there a technical reason why greybus files mix hyphen and underscore in their names? $ ls drivers/staging/greybus/arch* arche-apb-ctrl.c arche-platform.c arche_platform.h thanks, Tobin.

virtual USB device

by Greg Hazel

Hi, I’m working with Greybus and I’m wondering if there’s any support or code for virtual USB devices. On one side of Greybus I have a small nuttX environment with a UART connected device which I can write modules for, and on the other side of Greybus I’d like to provide a network interface. I can’t modify that side, so I have to work with the kernel modules it has available. I thought it might be possible to present a virtual USB CDC-EVM to Greybus, and my guess (hope) is that cdc_ether would pick it up on the other side. Is this possible? Has this sort of virtual USB device been created before? -Greg
