########
|
|
|
|
Genode comes with a growing number of components apparently scattered across
|
|
various repositories. This document provides an overview of these components
|
|
and outlines the systematics behind them.
|
|
|
|
The scope of this document is limited to the Genode main repository maintained
|
|
by Genode Labs. Many additional components and device drivers can be found in
|
|
the community-maintained
|
|
[https://github.com/genodelabs/genode-world/ - Genode-World] repository.

Categorization of components
|
|
############################
|
|
|
|
Genode components usually fall into one of four categories, namely device
|
|
drivers, resource multiplexers, protocol stacks, and applications. Each
|
|
of them is briefly characterized as follows:
|
|
|
|
:Device drivers: translate hardware resources into device-independent
|
|
session interfaces. Naturally, a device driver is specific to a
|
|
particular hardware platform. The hardware resources are accessed
|
|
via core's IO_MEM, IO_PORT, and IRQ services. The functionality of
|
|
the driver is made available to other system components via
|
|
one of Genode's device-independent session interfaces, which are
|
|
'platform_session', 'capture_session', 'event_session', 'block_session',
|
|
'record_session', 'play_session', 'log_session', 'uplink_session', and
|
|
'timer_session' (see _os/include/_ for the interface definitions).
|
|
Those interfaces are uniform across hardware platforms and kernel base
|
|
platforms. Usually, each device driver accommodates one client at a
|
|
time.
|
|
|
|
:Resource multiplexers: provide mechanisms to multiplex device resources
|
|
to multiple clients. A typical resource multiplexer requests one
|
|
of Genode's device-independent session interface (usually connected
|
|
to a device driver) and, in turn, announces a service of the same kind.
|
|
However, in contrast to a device driver, a resource multiplexer is able
|
|
to serve more than one client at the same time.
|
|
|
|
:Protocol stacks: translate low-level interfaces to higher-level
|
|
interfaces (or sometimes vice versa). Typically, a protocol stack comes
|
|
in the form of a library, which uses a device-independent session
|
|
interface as back end and provides a high-level library interface as
|
|
front end. However, protocol stacks also exist in the form of
|
|
distinct components that implement translations between different
|
|
session interfaces.
|
|
|
|
:Applications: implement functionality using APIs as provided by
|
|
protocol stacks.
|
|
|
|
:Runtime environments: enable existing 3rd-party software to be executed
|
|
as a Genode sub systems.
|
|
|
|
|
|
Device drivers
|
|
##############
|
|
|
|
Device drivers usually reside in the _src/driver/_ subdirectory of source-code
|
|
repositories. The most predominant repositories hosting device drivers are
|
|
'os', 'dde_ipxe', 'dde_linux', 'pc'. The main source tree is accompanied
|
|
by a variety of optional source-code repositories, each hosting the support of
|
|
a different SoC family such as NXP's i.MX, Allwinner, Xilinx Zynq, or RISC-V.

|
Platform devices
|
|
================
|
|
|
|
:_os/src/driver/platform/_: Platform drivers for various platforms.
|
|
On x86, the platform driver uses the PCI controller as found on x86 PC
|
|
hardware. A client can probe for a particular device and request information
|
|
about physical device resources (using the 'platform_device' interface). I/O
|
|
resources for MMIO regions, I/O ports, and interrupts can be requested by the
|
|
provided device abstraction.
|
|
|
|
:_os/src/driver/acpi/_:
|
|
On x86 platforms that use the APIC (namely Fiasco.OC, NOVA, and hw_x86_64)
|
|
this simple ACPI parser traverses the ACPI tables and reports device-resource
|
|
information (e.g., interrupt lines of PCI devices).
|
|
|
|
:_os/src/app/pci_decode/_:
|
|
A component that reports the physical information about PCI devices after
|
|
parsing and initializing the PCI bus. The reported information is usually
|
|
consumed by the platform driver.
|
|
|
|
:_os/src/app/smbios_decoder/_:
|
|
A component that parses SMBIOS information on x86 platforms and makes the
|
|
result available as a report.
|
|
|
|
:_libports/src/app/acpica/_:
|
|
In addition to our ACPI base driver, the acpica component uses the
|
|
ACPICA library to provide access to dynamic functions like battery
|
|
states, events (e.g., notebook lid close and power buttons), as well
|
|
as reset and power off. The componenten reports ACPI events and
|
|
states as reports and itself responds to system state changes of
|
|
certain configuration ROMs.
|
|
|
|
|
|
UART devices

|
|
VersatilePB. The physical base address used by the driver is obtained at
|
|
compile time from a header file called _pl050_defs.h_. The version of the
|
|
VersatilePB platform can be found at _os/include/platform/vpb926/_ and
|
|
is made available to the driver via the SPECS machinery of the Genode build
|
|
system.
|
|
|
|

|
The timer driver located at _base/src/timer/_ implements the timer-session
|
|
interface. Technically, it is both a device driver (accessing a timer
|
|
device) and a resource multiplexer (supporting multiple timer-session clients
|
|
at the same time). Depending on the base platform, the implementation uses
|
|
different time sources. Time sources are either hardware timers, a time source
|
|
provided by the kernel, or a pseudo time source (busy):

Resource multiplexers
|
|
#####################
|
|
|
|
By convention, resource multiplexers are located at the _src/server/_
|
|
subdirectory of a source repository.
|
|
|
|
:Framebuffer and input: Framebuffer and input devices can be multiplexed using
|
|
the Nitpicker GUI server, which allows multiple clients to create and manage
|
|
rectangular areas on screen. Nitpicker serves as broker between input
|
|
devices, output devices, and graphical applications. It provides an event
|
|
service for input drivers, a capture service for output drivers, and a GUI
|
|
service for the applications. Each GUI session contains a virtual
|
|
framebuffer and a virtual input interface. Nitpicker (including a README
|
|
file) is located at _os/src/server/nitpicker/_.
|
|
|
|
:Audio output: The audio mixer located at _os/src/server/record_play_mixer/_
|
|
allows for the routing and mixing of audio signals from play-session clients
|
|
to record-session clients.
|
|
|
|
:Networking: The NIC bridge located at _os/src/server/nic_bridge/_ multiplexes
|
|
one NIC session to multiple virtual NIC sessions using a proxy-ARP
|
|
implementation. Each client has to obtain a dedicated IP address visible to
|
|
the physical network. DHCP requests originating from the virtual NIC sessions
|
|
are delegated to the physical network.
|
|
|
|
The NIC router located at _os/src/server/nic_router/_ multiplexes one NIC
|
|
session to multiple virtual NIC sessions by applying network address
|
|
translation (NAT).
|
|
|
|
The NIC-uplink component located at _os/src/server/nic_uplink/_ connects
|
|
a NIC client directly to a network driver (as uplink client) without routing.
|
|
|
|
:Block: The block-device partition server at _os/src/server/part_block/_ reads
|
|
the partition table of a block session and exports each partition found as
|
|
separate block session. For using this server, please refer to the run
|
|
script at _os/run/part_block.run_.
|
|
|
|
:File system: The VFS file-system server allows multiple clients to
|
|
concurrently access the same virtual file system. It is located at
|
|
_os/src/server/vfs/_. The VFS can be assembled out of several builtin
|
|
file-system types (like a RAM file system, or pseudo file systems for
|
|
various Genode session interfaces) as well as external plugins such as rump
|
|
(mounting file systems supported by the NetBSD kernel).
|
|
|
|
:Terminal: The terminal_mux service located at _gems/src/server/terminal_mux/_
|
|
is able to provide multiple terminal sessions over one terminal-client
|
|
session. The user can switch between the different sessions using a keyboard
|
|
shortcut, which brings up an ncurses-based menu.
|
|
|
|
|
|
Protocol stacks
|
|
###############
|
|
|
|
Protocol stacks come either in the form of separate components that translate
|
|
one session interface to another, or in the form of libraries.
|
|
|
|
Separate components
|
|
===================
|
|
|
|
:_os/src/server/gui_fb/_:
|
|

information, please refer to _os/src/server/gui_fb/README_.
|
|
|
|
:_gems/src/server/wm/_:
|
|
Window manager that implements the GUI session interface but manages
|
|
each client view as a separate window. The window decorations are provided
|
|
by a so-called decorator (e.g., _gems/src/app/decorator/_). The behaviour
|
|
is defined by a so-called window layouter such as the floating window
|
|
layouter located at _gems/src/app/floating_window_layouter/_.
|
|
|
|
:_demo/src/server/liquid_framebuffer/_:
|
|
Implements the same translation as 'gui_fb' but by presenting an interactive
|
|
window rather than a statically positioned screen area.
|
|

|
|
content of the ROM dataspace to the LOG.
|
|
|
|

:_os/src/server/terminal_crosslink/_:
|
|
The terminal crosslink service allows to terminal clients to talk to each
|
|
other.
|
|
|
|
:_os/src/server/fs_rom/_:
|
|
A ROM service that translates the 'File_system' session interface to the
|
|
'ROM' session' interface. Each request for a ROM file is handled by looking
|
|
up an equally named file on the file system.
|
|
Please refer to _os/src/server/fs_rom/_ for more information.
|
|
|
|
For use cases where ROMs are known to be static, the

|
|
implement the VFS-plugin interface. They can be combined with any application
|
|
based on Genode's C runtime, with the VFS server, and with non-POSIX
