2 | # USB Gadget support on a system involves | |
3 | # (a) a peripheral controller, and | |
4 | # (b) the gadget driver using it. | |
5 | # | |
6 | # NOTE: Gadget support ** DOES NOT ** depend on host-side CONFIG_USB !! | |
7 | # | |
8 | # - Host systems (like PCs) need CONFIG_USB (with "A" jacks). | |
9 | # - Peripherals (like PDAs) need CONFIG_USB_GADGET (with "B" jacks). | |
cab00891 | 10 | # - Some systems have both kinds of controllers. |
1da177e4 LT |
11 | # |
12 | # With help from a special transceiver and a "Mini-AB" jack, systems with | |
13 | # both kinds of controller can also support "USB On-the-Go" (CONFIG_USB_OTG). | |

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 | |
e113f29c | 29 | familiar host side controllers have names like "EHCI", "OHCI", |
1da177e4 LT |
30 | 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. | |

105 | Usually 2 buffers are enough to establish a good buffering | |
106 | pipeline. The number may be increased in order to compensate | |
107 | for a bursty VFS behaviour. For instance there may be CPU wake up | |
108 | latencies that makes the VFS to appear bursty in a system with | |
109 | an CPU on-demand governor. Especially if DMA is doing IO to | |
110 | offload the CPU. In this case the CPU will go into power | |
111 | save often and spin up occasionally to move data within VFS. | |
112 | If selecting USB_GADGET_DEBUG_FILES this value may be set by | |
113 | a module parameter as well. | |
114 | If unsure, say 2. | |
