USB is a master/slave protocol, organized with one master
|
||
|
|
host (such as a PC) controlling up to 127 peripheral devices.
|
||
|
|
The USB hardware is asymmetric, which makes it easier to set up:
|
||
|
|
you can't connect a "to-the-host" connector to a peripheral.
|
||
|
|
|
||
|
|
Linux can run in the host, or in the peripheral. In both cases
|
||
|
|
you need a low level bus controller driver, and some software
|
||
|
|
talking to it. Peripheral controllers are often discrete silicon,
|
||
|
|
or are integrated with the CPU in a microcontroller. The more
|
||
|
|
familiar host side controllers have names like "EHCI", "OHCI",
|
||
|
|
or "UHCI", and are usually integrated into southbridges on PC
|
||
|
|
motherboards.
|
||
|
|
|
||
|
|
Enable this configuration option if you want to run Linux inside
|
||
|
|
a USB peripheral device. Configure one hardware driver for your
|
||
|
|
peripheral/device side bus controller, and a "gadget driver" for
|
||
|
|
your peripheral protocol. (If you use modular gadget drivers,
|
||
|
|
you may configure more than one.)
|
||
|
|
|
||
|
|
If in doubt, say "N" and don't enable these drivers; most people
|
||
|
|
don't have this kind of hardware (except maybe inside Linux PDAs).

||

Usually 2 buffers are enough to establish a good buffering

|

for a bursty VFS behaviour. For instance there may be CPU wake up

latencies that makes the VFS to appear bursty in a system with
|
||
|
|
an CPU on-demand governor. Especially if DMA is doing IO to

offload the CPU. In this case the CPU will go into power

A Linux "Gadget Driver" talks to the USB Peripheral Controller
|

|
driver through the abstract "gadget" API. Some other operating
|
||
|
|
systems call these "client" drivers, of which "class drivers"
|
||
|
|
are a subset (implementing a USB device class specification).
|
||
|
|
A gadget driver implements one or more USB functions using
|
||
|
|
the peripheral hardware.
|
||
|
|
|
||
|
|
Gadget drivers are hardware-neutral, or "platform independent",
|
||
|
|
except that they sometimes must understand quirks or limitations
|
||
|
|
of the particular controllers they work with. For example, when
|
||
|
|
a controller doesn't support alternate configurations or provide
|
||
|
|
enough of the right types of endpoints, the gadget driver might
|
||
|
|
not be able work with that controller, or might need to implement
|
||
|
|
a less common variant of a device class protocol.
