b5d3be9c85 run: add nic driver performance test
A run script which sends raw ethernet packets from the host machine to the
target machine. Three tests are implemented:
- The network_stat instrumented driver of usb_drv and net_drv
  are used to get the raw receive performance of the network driver.
- A simple nic_session client is receiving from the un-instrumented network
  driver raw ethernet packets.
- A bridge is added between driver and simple nic_session client.

ea3adfef9a Create the context area RM session at startup
With this patch, the thread context area RM session gets created at
program startup to have the thread context area's virtual address range
reserved right from the beginning.

Fixes #734.

This patch implies that all Genode processes try to create an RM
session. So a route to the RM service must be present even for processes
that have only a single thread. Hence, the patch contains an update of
affected components.

cc5fddb0a2 Loader: Free entries of parent-service registry
The parent-service registry is populated on demand by the
'Loader::Child' whenever a prior unknown service is requested. Since the
number of parent services is limited, we expect the registry to settle
after a while. However, each loader session has a private instance of
a parent-service registry. So when creating and destroying loader
sessions, parent registries will be populated again and again. We
have to make sure to discard the entries along with the destruction
of a loader session to avoid the leakage of memory.

1500d59d0d nic_bridge: drop 'gratuitous ARP' messages
'Gratuitous ARP' broadcast messages are used to announce newly created
IP<->MAC address mappings to other hosts. nic_bridge-internal hosts
would expect a nic_bridge-internal MAC address in this message, whereas
external hosts would expect the NIC's MAC address in this message.
The simplest solution to this problem is to just drop those messages,
since they are not really necessary.

439315d918 timer: Don't set default cap as custom cap
Without the patch the signal cap was ever transferred to the timer session
when a usleep/msleep was called, even when unneeded. On base-nova this
causes the allocation of new capability indexes which are not freed up.
So the timer service run quickly out of indexes and get out of order...

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.

20a5c86a22 timer: Build platform-specific parts as lib
By using the build system's library-selection mechanism instead of many
timer targets with different 'REQUIRES' declarations, this patch reduces
the noise of the build system. For all platforms, the target at
'os/src/drivers/timer' is built. The target, in turn, depends on a
'timer' library, which is platform-specific. The various library
description files are located under 'os/lib/mk/<platform>'. The common
bits are contained in 'os/lib/mk/timer.inc'.

3049c1004c Turn 'Timer::Session' into asynchronous interface
The 'Timer::Session::msleep' function is one of the last occurrences of
long-blocking RPC calls. Synchronous blocking RPC interfaces turned out
to be constant source of trouble and code complexity. I.e., a timer
client that also wants to respond to non-timer events was forced to be a
multi-threaded process. This patch replaces the blocking 'msleep' call
by a mechanism for programming timeouts and receiving wakeup signals in
an asynchronous fashion. Thereby signals originating from the timer can
be handled along with signals from other signal sources by a single
thread.

The changed interface has been tested on Linux, L4/Fiasco, OKL4, NOVA,
L4ka::Pistachio, Codezero, Fiasco.OC, and hw_pbxa9. Furthermore, this
patch adds the timer test to autopilot.

ecdbdef8ee Loader: reflect faults to client
With this patch, the loader installs an optional client-provided fault
handler as default CPU exception handler and RM fault handler for all
CPU and RM sessions of the loaded subsystem. This way, loader clients
become able to respond to failures occuring within the subsystem.

The new feature is provided via the added 'Loader::fault_handler' RPC
function.

The 'run/failsafe' test covers two cases related to the loader, which
are faults produced by the immediate child of the loader and faults
produced by indirect children.

959df5d46b Generalize handling of PD-session arguments
On Linux, we want to attach additional attributes to processes, i.e.,
the chroot location, the designated UID, and GID. Instead of polluting
the generic code with such Linux-specific platform details, I introduced
the new 'Native_pd_args' type, which can be customized for each
platform. The platform-dependent policy of init is factored out in the
new 'pd_args' library.

The new 'base-linux/run/lx_pd_args.run' script can be used to validate
the propagation of those attributes into core.

Note that this patch does not add the interpretation of the new UID and
PID attributes by core. This will be subject of a follow-up patch.

bcabbe2c92 Add 'Thread_base::join()'
Using the new 'join()' function, the caller can explicitly block for the
completion of the thread's 'entry()' function. The test case for this
feature can be found at 'os/src/test/thread_join'. For hybrid
Linux/Genode programs, the 'Thread_base::join()' does not map directly
to 'pthread_join'. The latter function gets already called by the
destructor of 'Thread_base'. According to the documentation, subsequent
calls of 'pthread_join' for one thread may result in undefined behaviour.
So we use a 'Genode::Lock' on this platform, which is in line with the
other platforms.

b45242c50f Add chroot support to core
Since the recent move of the process creation into core, the original chroot trampoline
mechanism implemented in 'os/src/app/chroot' does not work anymore. A
process could simply escape the chroot environment by spawning a new
process via core's PD service. Therefore, this patch moves the chroot
support into core. So the chroot policy becomes mandatory part of the
process creation.  For each process created by core, core checks for
'root' argument of the PD session. If a path is present, core takes the
precautions needed to execute the new process in the specified chroot
environment.

This conceptual change implies minor changes with respect to the Genode
API and the configuration of the init process. The API changes are the
enhancement of the 'Genode::Child' and 'Genode::Process' constructors to
take the root path as argument. Init supports the specification of a
chroot per process by specifying the new 'root' attribute to the
'<start>' node of the process. In line with these changes, the
'Loader::Session::start' function has been enhanced with the additional
(optional) root argument.

94ea3a0acb Move away drivers from generic base-repository
Driver definitions which are used by kernel/core in base-hw, and also by other
drivers (e.g. from the os repository) have to reside in the generic
base-repository, for instance some uart drivers. All drivers which are
interesting for one of the sites only (sp804 for timer driver, or
cortex_a9 cpu driver for base-hw) should reside in the respective repos.

Factorize cpu context out of Cortex A9 specific definitions. Moreover, there
is already a Cpu_state object containing all common ARM registers. We use
this as a base for the cpu context switching done by the base-hw kernel.
The Cpu_state class get extended by a cpu-exception field, that stores the kind
of exception raised when the corresponding context got interrupted. This
information is used not only by the base-hw kernel, but also by the TrustZone
VMM that is build currently.

6862ab481a NOVA: drop special utcb handling of main thread
Unify handling of UTCBs. The utcb of the main thread is with commit
ea38aad30e at a fixed location - per convention.
So we can remove all the ugly code to transfer the utcb address during process
creation.

To do so also the UTCB of the main thread of Core must be inside Genode's
thread context area to handle it the same way. Unfortunately the UTCB of the
main thread of Core can't be chosen, it is defined by the kernel.

Possible solutions:
- make virtual address of first thread UTCB configurable in hypervisor
- map the utcb of the first thread inside Core to the desired location

This commit implements the second option.

Kernel patch: make utcb map-able
With the patch the Utcb of the main thread of Core is map-able.

Fixes #374

Noux actually uses the sp variable during thread creation and expects to be
set accordingly. This wasn't the case for the main thread, it was ever set
to the address of the main thread UTCB.

9651974448 Add stdcxx-4.6.1 to libports, fix #339
This patch adds libstdc++ to libports. With the previous version of the

comes with the compiler. This mechanism was prone to inconsistencies of
types defined in the header files used at compile time of the tool chain
and the types provided by our libc. By building the C++ standard library
as part of the Genode build process, such inconsistencies cannot happen
anymore.

Note that the patch changes the meaning of the 'stdcxx' library for
users that happened to rely on 'stdcxx' for hybrid Linux/Genode
applications. For such uses, the original mechanism is still available,
in the renamed form of 'toolchain_stdcxx'.

0f6110ea97 Let OMAP4 SD-card driver use DMA and interrupts
With this patch, the driver code gets complemented with DMA support.
The support for master DMA, in turn, cleared the way for using
interrupts to wait for the completion of transfers, which largely
relieves the CPU compared to the polling PIO mode. Consequently, the new
version has a much lower CPU footprint.

In the current version, both modes of operation PIO and DMA are
functional. However, PIO mode is retained for benchmarking purposes only
and will possibly be removed to keep the driver simple. It is disabled
in the driver's 'main.cc'.

e9497a183f Improve measurement accuracy
This patch replaces the jiffies thread in 'sd_card/omap4/bench' calls to
'Timer::Session::elapsed_ms()'. This way, we use wall-clock time for the
measurements. Depending on the load of the rest of the system, the
previous version used to accumulate the inaccuracy for each 'msleep'
call.

0ca47e8963 Support uncached 'Attached_ram_dataspace'
The enable the use of 'Attached_ram_dataspace' objects as DMA buffers,
we need to pass the 'cached' flag to the constructor. By default, the
dataspace is cached, which corresponds to the original behaviour.

e1435a3f57 Replace old test/block with test/ahci
The block test at test/ahci is indeed not AHCI-specific. It is a generic
block read/write test for the block-session interface. But in contrast
to the original test/block, it restores the block device content (at
least when the test succeeds). Hence, we remove the original (dangerous)
block test and always use code of test/ahci.

5cd099ed90 OMAP4 SD card driver
The new SD card driver at 'os/src/drivers/sd_card/omap4' allows the use
of an SD card with the Pandaboard as block service. Currently, the
driver is using PIO, no DMA, and no IRQs. The driver can be tested using
the 'os/run/sd_card.run' script.

12f2572155 Resolve ambiguity of size_t
This patch replaces the first attempt to resolve the ambiguity of using
the size_t type that occurred when 'loader_session.h' was included
alongside libc headers. Instead of explicitly qualifying each occurrence
of the type, the new solution defines 'size_t' within the 'Loader' namespace.
