20 USB is a master/slave protocol, organized with one master
21 host (such as a PC) controlling up to 127 peripheral devices.
22 The USB hardware is asymmetric, which makes it easier to set up:
23 you can't connect a "to-the-host" connector to a peripheral.
24
25 Linux can run in the host, or in the peripheral. In both cases
26 you need a low level bus controller driver, and some software
27 talking to it. Peripheral controllers are often discrete silicon,
28 or are integrated with the CPU in a microcontroller. The more
Jules Villarde113f292006-08-22 22:40:15 +020029 familiar host side controllers have names like "EHCI", "OHCI",
Linus Torvalds1da177e2005-04-16 15:20:36 -070030 or "UHCI", and are usually integrated into southbridges on PC
31 motherboards.
32
33 Enable this configuration option if you want to run Linux inside
34 a USB peripheral device. Configure one hardware driver for your
35 peripheral/device side bus controller, and a "gadget driver" for
36 your peripheral protocol. (If you use modular gadget drivers,
37 you may configure more than one.)
38
39 If in doubt, say "N" and don't enable these drivers; most people
40 don't have this kind of hardware (except maybe inside Linux PDAs).
41
42 For more information, see <http://www.linux-usb.org/gadget> and
43 the kernel DocBook documentation for this API.

122 latencies that makes the VFS to appear bursty in a system with
123 an CPU on-demand governor. Especially if DMA is doing IO to
124 offload the CPU. In this case the CPU will go into power
125 save often and spin up occasionally to move data within VFS.

127 a module parameter as well.

729 Gadget Zero is a two-configuration device. It either sinks and
730 sources bulk data; or it loops back a configurable number of
731 transfers. It also implements control requests, for "chapter 9"
732 conformance. The driver needs only two bulk-capable endpoints, so
733 it can work on top of most device-side usb controllers. It's
734 useful for testing, and is also a working example showing how
735 USB "gadget drivers" can be written.
736
737 Make this be the first driver you try using on top of any new
738 USB peripheral controller driver. Then you can use host-side
739 test software, like the "usbtest" driver, to put your hardware
740 and its driver through a basic set of functional tests.
741
742 Gadget Zero also works with the host-side "usb-skeleton" driver,
743 and with many kinds of host-side test software. You may need
744 to tweak product and vendor IDs before host software knows about
745 this device, and arrange to select an appropriate configuration.

747 Say "y" to link the driver statically, or "m" to build a
748 dynamically linked module called "g_zero".

754 You can configure this device to enumerate using the device
755 identifiers of the USB-OTG test device. That means that when
756 this gadget connects to another OTG device, with this one using
757 the "B-Peripheral" role, that device will use HNP to let this
758 one serve as the USB host instead (in the "B-Host" role).

Brian Niebuhr9b39e9d2009-08-14 10:04:22 -0500798 This driver implements Ethernet style communication, in one of
799 several ways:
Linus Torvalds1da177e2005-04-16 15:20:36 -0700800
801 - The "Communication Device Class" (CDC) Ethernet Control Model.
802 That protocol is often avoided with pure Ethernet adapters, in
803 favor of simpler vendor-specific hardware, but is widely
804 supported by firmware for smart network devices.
805
806 - On hardware can't implement that protocol, a simple CDC subset
807 is used, placing fewer demands on USB.
808
Brian Niebuhr9b39e9d2009-08-14 10:04:22 -0500809 - CDC Ethernet Emulation Model (EEM) is a newer standard that has
810 a simpler interface that can be used by more USB hardware.
811
812 RNDIS support is an additional option, more demanding than than
813 subset.
Linus Torvalds1da177e2005-04-16 15:20:36 -0700814
815 Within the USB device, this gadget driver exposes a network device
816 "usbX", where X depends on what other networking devices you have.
817 Treat it like a two-node Ethernet link: host, and gadget.
818
819 The Linux-USB host-side "usbnet" driver interoperates with this
820 driver, so that deep I/O queues can be supported. On 2.4 kernels,
821 use "CDCEther" instead, if you're using the CDC option. That CDC
822 mode should also interoperate with standard CDC Ethernet class
823 drivers on other host operating systems.

855 CDC EEM is a newer USB standard that is somewhat simpler than CDC ECM
856 and therefore can be supported by more hardware. Technically ECM and
857 EEM are designed for different applications. The ECM model extends
858 the network interface to the target (e.g. a USB cable modem), and the
859 EEM model is for mobile devices to communicate with hosts using
860 ethernet over USB. For Linux gadgets, however, the interface with
861 the host is the same (a usbX device), so the differences are minimal.
862
863 If you say "y" here, the Ethernet gadget driver will use the EEM
864 protocol rather than ECM. If unsure, say "n".

1055 and phonet in only one composite gadget driver.
1056
1057 It's only really useful for N900 hardware. If you're building
1058 a kernel for N900, say Y or M here. If unsure, say N.
