Setting the ACTLR.SMP bit also without SMP support fastens RAM access
significantly. A proper solution would implement SMP support which must enable
the bit anyway.
Fixes#1353
and move it close to run_genode_until implementation.
Somehow the "match_max -d" gets ignored if it is to far away and some
our run scripts fails because the buffer contains not all information
(seen for affinity.run on a 8 core machine)
This is needed at least by rump_ext2.run as it uses the perf-counter
in the jitterentropy-lib. On other platforms the perf-counter gets enabled
by the kernel by default. However, on HW, we keep the specifier to allow users
to disable it easily (e.g. for security reasons).

When returning early on directory operations, file systems that might
be able to handle the request but come after the current one are not
tried.
Fixes#1400.
Up to now Noux used the libc sleep functions, which actually is not
possible because the _nanosleep() function implemented by our libc
creates a new thread to handle the timeout. Noux childs may have
only one thread, e.g., the main thread, though. To fix this issue
sleeping is now handled directly by Noux. It is implemented by calling
select(2) with a timeout. This fix is needed for mutt(1), which calls
sleep when it prints a notification for the user.
Fixes#1374.
Since rump now requires large buffers of random numbers (>= 512 bytes), use the
jitterentropy library instead of the slow timer pseudo random number generation.
Fixes#1393
To circumvent compilation errors with the older L4Android Linux kernel
version, the ballooning driver is included in the more recent L4Linux
kernel only. Moreover, to be able to maintain L4Android / L4Linux in a more
convenient way, e.g. to apply patches valid for both versions, we use
the same git clone that is used for L4Linux instead of using the upstream
L4Android version by applying patches.
Fixes#1390
Instead of returning an uint64_t value, return a structured time stamp.
This change is only visible to components using Rtc_session directly.
Fixes#1381.
Up until now 'schedule_timeout' did only wait for the next signal to occur.
However, we might run into situations where there won't occur signals for longer
periods of time. Therefore, we took care of the respective timeout handling.
This commit also adds Genode's tracing support
Issue #1310
This has been broken for a while now. Use correct (global) signal transmission,
do not use local signal transmission, as signals seems to get lost.
Issue #1310
This patch changes the Shared_object::lookup function to use a
reinterpret_cast instead of a static_cast to allow the conversion
from symbol addresses to arbitrary pointers.
By blocking on a timeout, we yield the CPU in order to give a
concurrently running sporadic process a chance to obtain ROM modules.
Otherwise, such requests would be deferred until the ROM prefetcher
completes its operation or in the unlikely event that the prefetcher
gets preempted.
Fixes#1378
