Norman Feske fae63f4fa9 Merge base libraries into a single library This patch simplifies the way of how Genode's base libraries are organized. Originally, the base API was implemented in the form of many small libraries such as 'thread', 'env', 'server', etc. Most of them used to consist of only a small number of files. Because those libraries are incorporated in any build, the checking of their inter-dependencies made the build process more verbose than desired. Also, the number of libraries and their roles (core only, non-core only, shared by both core and non-core) were not easy to capture. Hereby, the base libraries have been reduced to the following few libraries: - startup.mk contains the startup code for normal Genode processes. On some platform, core is able to use the library as well. - base-common.mk contains the parts of the base library that are identical by core and non-core processes. - base.mk contains the complete base API implementation for non-core processes Consequently, the 'LIBS' declaration in 'target.mk' files becomes simpler as well. In the most simple case, only the 'base' library must be mentioned. Fixes #18		2013-02-19 14:45:55 +01:00

Device drivers ported from the Linux kernel

USB
###

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>
!    <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>


Network (Nic)
~~~~~~~~~~~~~

Supported on PandaBoard only using the 'smsc95xx' driver.

Configuration snippet:

!<start name="usb_drv">
!  <resource name="RAM" quantum="3M"/>
!  <provides>
!    <service name="Nic"/>
!    <service name="Input"/>
!  </provides>
!  <config>
!    <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.
