Unregister callbacks, so rx packets will not be propated to the deleteted
'Driver' object. Initialize ipxe once in the 'Main' object, thus allowing new
session connections.
Fixes#1595
With the server framework this becomes unnecessary. Also when the 'platform_drv'
has a lower priority, signaling will cause a constant load that starves the
'platform_drv'.
Fixes#1594
The recent change of the TRACE session interface triggered the
following warning:
/home/no/src/genode/repos/base/include/base/ipc.h:79:4: warning: ‘ret’ may be used uninitialized in this function [-Wmaybe-uninitialized]
*reinterpret_cast<T *>(&_sndbuf[_write_offset]) = value;

/home/no/src/genode/repos/base/include/base/rpc_server.h:132:42: note: ‘ret’ was declared here
typename This_rpc_function::Ret_type ret;
The warning occurs for basic return types (like size_t), which are
indeed not initialized. The variable gets its value assigned by the
corresponding 'call_member' overload, to which the variable is passed as
reference. But the compiler apparently is not able to detect this assignment.
Declaring 'ret' with a C++11-style default initializer fixes the warning.
While importing trace sources as trace subjects into a TRACE session,
the session quota might become depleted. The TRACE session already keeps
track of the session quota via an allocator guard but the 'subjects' RPC
function missed to handle the out-of-memory condition. This patch
reflects the error condition as an 'Out_of_metadata' exception to the
TRACE client. It also contains an extension of the trace test to
exercise the corner case.
This patch enable clients of core's TRACE service to obtain the
execution times of trace subjects (i.e., threads). The execution time is
delivered as part of the 'Subject_info' structure.
Right now, the feature is available solely on NOVA. On all other base
platforms, the returned execution times are 0.
Issue #813
This patch bases the size of the destination buffer in
'Init::Child_policy_redirect_rom_file' on the maximum label size
instead of the filename size. Otherwise, the use of a long configfile
name (i.e., "trace_subject_reporter.config") in combination with a long
child name ("trace_subject_reporter") would result in a truncated label
string.
When replacing a report with a smaller one, the corresponding ROM
dataspace should not contain any traces of the old report. Otherwise,
the consumer of the ROM dataspace may mistake the stale content as
meaningful information. This is particularly annoying when manually
inspecting reports. This patch overwrites the stale content with zeros.
By appending a newline to the generated XML data, we prevent the output
from messing with the command prompt when using 'cat' on a shell.
Futhermore, when using line-buffered output, the trailing newline
ensures that the output gets gets properly flushed.
The result of the second run (TCP_MAERTS) gets extracted wrongly - due to the
change introduced by commit "run: always append to output buffer"
(Issue #1327). The output buffer is no longer reseted between several
run_genode_until invocation within a run script.
