Stefan Kalkowski 50d73e7890 block_session: extend interface with sync() call To support components, which implement the block session's server side rpc object, and which doesn't write data to their device backend immediately, an additional synchronization call is needed. Thereby, clients like for instance a file system can tell these components, when a synchronization is required. Ref #113		2013-11-25 12:12:31 +01:00

Device drivers ported from the Linux kernel

USB
###

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.
