config USBIP_CORE
tristate "USB/IP support"
depends on NET
select USB_COMMON
---help---
This enables pushing USB packets over IP to allow remote
machines direct access to USB devices. It provides the
USB/IP core that is required by both drivers.
For more details, and to get the userspace utility
programs, please see <http://usbip.sourceforge.net/>.
To compile this as a module, choose M here: the module will
be called usbip-core.
If unsure, say N.
config USBIP_VHCI_HCD
tristate "VHCI hcd"
depends on USBIP_CORE && USB
---help---
This enables the USB/IP virtual host controller driver,
which is run on the remote machine.
To compile this driver as a module, choose M here: the
module will be called vhci-hcd.
usbip: vhci extension: modifications to vhci driver Modification to Kconfig, vhci_hc.c, vhci.h and vhci_sysfs.c. 1. kernel config Followings are added. USBIP_VHCI_HC_PORTS: Number of ports per USB/IP virtual host controller. The default is 8 - same as current VHCI_NPORTS. USBIP_VHCI_NR_HCS: Number of USB/IP virtual host controllers. The default is 1. This paratmeter is replaced with USBIP_VHCI_INIT_HCS and USBIP_VHCI_MAX_HCS included in succeeding dynamic extension patch. 2. the_controller to controllers the_controller is changed to vhci_pdevs: array of struct platform_device. 3. vhci_sysfs.c Sysfs structure is changed as following. BEFORE: /sys/devices/platform +-- vhci +-- status +-- attach +-- detach +-- usbip_debug AFTER: example for CONFIG_USBIP_NR_HCS=4 /sys/devices/platform +-- vhci | +-- nports | +-- status | +-- status.1 | +-- status.2 | +-- status.3 | +-- attach | +-- detach | +-- usbip_debug +-- vhci.1 +-- vhci.2 +-- vhci.3 vhci[.N] is shown for each host controller kobj. vhch.1, vhci.2, ... are shown only when CONFIG_USBIP_NR_HCS is more than 1. Only 'vhci' (without number) has user space interfaces. 'nports' is newly added to give ports-per-controller and number of controlles. Before that, number of ports is acquired by reading status lines. Status is divided for each controller to avoid page size (4KB) limitation. Old userspace tool binaries work with the first status within the first controller. Inconsistency between status header and content is fixed. 4th and 5th column are header: "dev bus" content(unused): "000 000" content(used): "%08x", devid Only 1st and 2nd column are used by program. In old version, sscanf() in parse_status expect no bus column. And bus_id string is shown in the last column. Then bus in the header is removed and unused content is replaced with 8 zeros. The sscanf() expects more than 5 columns and new has 6 columns so there's no compatibility issue in this change.

default 8
depends on USBIP_VHCI_HCD
---help---
To increase number of ports available for USB/IP virtual
host controller driver, this defines number of ports per
USB/IP virtual host controller.
config USBIP_VHCI_NR_HCS
int "Number of USB/IP virtual host controllers"
range 1 128
default 1
depends on USBIP_VHCI_HCD
---help---
To increase number of ports available for USB/IP virtual
host controller driver, this defines number of USB/IP
virtual host controllers as if adding physical host
controllers.
config USBIP_HOST
tristate "Host driver"
depends on USBIP_CORE && USB
---help---
This enables the USB/IP host driver, which is run on the
machine that is sharing the USB devices.
To compile this driver as a module, choose M here: the
module will be called usbip-host.
config USBIP_VUDC
tristate "VUDC driver"
depends on USBIP_CORE && USB_GADGET
---help---
This enables the USB/IP virtual USB device controller
driver, which is run on the host machine, allowing the
machine itself to act as a device.
To compile this driver as a module, choose M here: the
module will be called usbip-vudc.
config USBIP_DEBUG
bool "Debug messages for USB/IP"
depends on USBIP_CORE
