This patch changes both the Input::Session interface and the skeleton
for the server-side implementation of this interface
('input/component.h').
The Input::Session interface offers a new 'sigh' function, which can be
called be the client to register a signal handler. The signal handler
gets notified on the arrival of new input. This alleviates the need to
poll for input events at the client side.
The server-side skeleton for implementing input services underwent a
redesign to make it more modular and robust. I.e., there are no
global functions needed at the server side and the event-queue
enable/disable mechanism is implemented at a central place (in the root
component) rather than inside each driver.
Fixes #46
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. LXIP #### LXIP is a port of the Linux TCP/IP stack to Genode. It is build as a shared library named 'lxip.lib.so'. The IP stack can be interfaced using Genode's version of 'libc' by linking your application to 'lxip_libc' plugin in your 'target.mk' file.
