|
Controller configuration
|
|
~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The driver can be started using different or all USB controller types a platform
|
|
offers (USB 1.0/2.0/3.0). Note that not all controllers are supported by all
|
|
platforms. Controllers can be enabled as attribute in the config node of the
|
|
driver. Supported attributes are: 'uhci', 'ehci', and 'xhci'.
|
|
|
|
|
|
Configuration snippet to enable UHCI and EHCI
|
|
|
|
! <config uhci="yes" ehci="yes">
|
|
|
|
HID
|
|
~~~
|
|
|
|
Supports keyboard and mouse. A run script can be found under 'run/usb_hid.run'.
|
|
|
|
Configuration snippet:
|
|
|
|
!<start name="usb_drv">
|
|
! <resource name="RAM" quantum="3M"/>
|
|
! <provides><service name="Input"/></provides>
|
|
! <config uhci="yes" ehci="yes" xhci="yes">
|
|
! <hid/>
|
|
! </config>
|
|
!</start>
|
|
|
|
Note: It has been observed that certain 1.0 versions of Qemu do not generate
|
|
mouse interrupts. The mouse driver should work correctly on Qemu 1.0.93 and
|
|
above.
|
|
|
|
Storage
|
|
~~~~~~~
|
|
|
|
Currently supports one USB storage device. Hot plugging has not been tested. A
|
|
run script can be found under 'run/usb_storage.run'.
|
|
|
|
Configuration snippet:
|
|
|
|
!<start name="usb_drv">
|
|
! <resource name="RAM" quantum="2M"/>
|
|
! <provides> <service name="Block"/> </provides>
|
|
! <config><storage /></config>
|
|
!</start uhci="yes">
|
|
|
|
|
|
Network (Nic)
|
|
~~~~~~~~~~~~~
|
|
|
|
Configuration snippet:
|
|
|
|
!<start name="usb_drv">
|
|
! <resource name="RAM" quantum="3M"/>
|
|
! <provides>
|
|
! <service name="Nic"/>
|
|
! <service name="Input"/>
|
|
! </provides>
|
|
! <config ehci="yes" xhci="yes">
|
|
! <nic mac="2e:60:90:0c:4e:01" />
|
|
! <hid/>
|
|
! </config>
|
|
!</start>
|
|
|
|
Please observe that this setup starts the HID and Nic service at the same time.
|
|
Also there is the 'mac' attribute where one can specify the hardware address of
|
|
the network interface. This is necessary in case the EEPROM of the network card
|
|
cannot be accessed via the host controller making it impossible to retrieve the
|
|
devices hardware address. If this is the case and no 'mac' attribute is given a
|
|
fallback address will be assigned to the network device. Note that the fallback
|
|
address will always be the same.
