Stefan Kalkowski 5447c406e5 thread: rearrange thread context management Use a bit allocator for the allocation management of thread contexts, instead of holding allocation information within the Thread_base objects, which lead to race conditions in the past. Moreover, extend the Thread_base class interface with the ability to to add additional stacks to a thread, and associate the context they're located in with the corresponding Thread_base object. Additional stacks can be used to do user-level scheduling with stack switching, without breaking Genode's API. Fixes #1024 Fixes #1036		2014-01-27 18:54:09 +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.

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.
