This patch adjusts the various users of the 'Child' API to the changes
on the account of the new non-blocking parent interface. It also removes
the use of the no-longer-available 'Connection::KEEP_OPEN' feature.
With the adjustment, we took the opportunity to redesign several
components to fit the non-blocking execution model much better, in
particular the demo applications.
Issue #2120
VirtualBox mainly derives the initial link-state for its device models
from checking the <Adapter ... cable="true"/> attribute. Our backend
only propagates the current state of the Nic session if it receives a
link-state signal. This may lead to problems if a guest detects a link
up state when it is actually down and wants to use the interface. The
backend now queries the Nic session and sets the link-state accordingly
when it is constructed.
In case there is no link do not attempt to submit a packet to the packet
stream but return with an error so that upper layers can handle it.
Enable signals for network on poweron and not already during
construction. The network model may be not yet ready to process incoming
signals and data.
Fixes#2117.
Prepared for internal test machine, which has 8 logical cores.
6 Win7 64bit VMs are started, each having 2 vCPUs, using the same image and
different overlays. Changes to the VM are written to the overlays of ram_fs
and dropped after the test.

Ref #1987
This patch makes the build-system integration of noux packages usable
for non-Noux targets. It moves the GNU build system wrapper to
ports/mk/gnu_build.mk, which is now included by noux.mk. This way,
non-noux applications can use the same build-system wrapper. So the
porting of individual applications becomes easier.
This change removes the 'NOUX_' prefix use the various build variables
used by the noux-pkg's target.mk files to steer the behaviour of the GNU
build system. E.g., NOUX_CONFIGURE_ARGS is now called CONFIGURE_ARGS.
Note that there is a single exception to this pattern: The formerly
named NOUX_LIBS is now called LDLIBS because the plain LIBS variable is
used by the Genode build system.
Fixes#2094
The main feature for this version upgrade is the use of the instruction
emulator (IEM) to speed up execution and less often the slow recompiler.
issue #2059
Besides adapting the components to the use of base/log.h, the patch
cleans up a few base headers, i.e., it removes unused includes from
root/component.h, specifically base/heap.h and
ram_session/ram_session.h. Hence, components that relied on the implicit
inclusion of those headers have to manually include those headers now.
While adjusting the log messages, I repeatedly stumbled over the problem
that printing char * arguments is ambiguous. It is unclear whether to
print the argument as pointer or null-terminated string. To overcome
this problem, the patch introduces a new type 'Cstring' that allows the
caller to express that the argument should be handled as null-terminated
string. As a nice side effect, with this type in place, the optional len
argument of the 'String' class could be removed. Instead of supplying a
pair of (char const *, size_t), the constructor accepts a 'Cstring'.
This, in turn, clears the way let the 'String' constructor use the new
output mechanism to assemble a string from multiple arguments (and
thereby getting rid of snprintf within Genode in the near future).
To enforce the explicit resolution of the char * ambiguity, the 'char *'
overload of the 'print' function is marked as deleted.
