4fa0cb5c29 timer pit: handle and display bad latency
If the PIT timer driver gets activated too slow (e.g. because of a bad priority
configuration), it might miss counter wraps and would than produce sudden time
jumps. The driver now detects this problem dynamically, warns about it and
adapts the affected values to avoid time jumps.

555ebe1ffe okl4: copy elfweaver tool to build directory
When using the elfweaver to generate boot images, python stores
precompiled modules in the source directory besides the .py files. This
changed the contrib source tree with binary files specific to the build
host. As a result the depot create tool picked up the changed source
tree and produced strange new hashes. Now, the tool sources are copied
to the build directory where python can do its optimizations and the
depot stays clean.

82c763fe75 nic_router: provide link state
The NIC router always reports the link state "Up" (true) because
the effective link state depends on the targeted remote interface
and thus on the individual routing for each packet. Consequently,
also the signal handler for state changes gets ignored.

a1e32a3ad9 nic_router: use local but individual MAC addresses
IP stacks may treat a network interface as "down" when it states a MAC
address with the I/G bit (bit 40) set to "Group" (value 0) instead of
"Individual" (value 1). This was observed with a TinyCore 8 inside a
Virtualbox VM. Thus, the previously choosen 03:03:03:03:03:00 as base
for the MAC address allocator is bad. Now we use the 02:02:02:02:02:00
instead. This also ensures that the MAC addresses are not marked as
"Universal" but as "Local" (bit 41, value 1) which is correct in general
as the router allocates MAC addresses only for virtual networks.

84ad50b527 nic_dump: synchronize down/uplink creation
Previously, the uplink session was created on component startup while the
creation of the downlink session is timed by the client component. This

nic_dump. Now the uplink session-request is done by the session component
of the downlink.

7f29eff75a hw lapic: find best frequency dynamically
Some x86 machines do have a LAPIC speed < 1000 ticks per millisecond
when configured to use the maximum divider (as it was always the case).
But we need microseconds precision for the timeout framework. Thus,
reduce the divider dynamically until the frequency fullfills our
requirements.

399e1586be timer: generic timer_ticks_to_us implementation
There are hardware timers whose frequency can't be expressed as
ticks-per-microsecond integer-value because only a ticks-per-millisecond
integer-value is precise enough. We don't want to use expensive
floating-point values here but nonetheless want to translate from ticks
to time with microseconds precision. Thus, we split the input in two and
translate both parts separately. This way, we can raise precision by
shifting the values to their optimal bit position. Afterwards, the results
are shifted back and merged together again.

As this algorithm is not so trivial anymore and used by at least three
timer drivers (base-hw/x86_64, base-hw/cortex_a9, timer/pit), move it to a
generic header to avoid redundancy.

22294d3b18 timer connection: fix division by null
When synchronizing with the remote time source, we have to take care that the
measured time difference cannot become null because its real value is smaller
than the measurement granularity. Since the granularity is one microsecond, we
simply go on polling timestamp and time until the microsecond has passed.
This busy waiting should be no problem for the system for two reasons. First,
it is limited to a relatively small amount of time and second, a busy lock
does not happen because the time source that is responsible for the limiting
factor is explicitely called on each poll.

ee352abc56 run: add Xen support
When building Genode on a Linux system running in a Xen Dom0, the 'xen'
run target can run a Genode scenario in a Xen DomU.

Usage: in build/x86_*/etc/build.conf, define:

RUN_OPT = --include boot_dir/$(KERNEL) --include image/iso --include power_on/xen --include log/xen --include power_off/xen

The Xen DomU runs in HVM mode and loads Genode from an ISO image. Serial
log output is printed to the console and graphical output is shown in an
SDL window.

The Xen DomU ist managed using the 'xl' command line tool and it is
possible to add configuration options in the 'xen_args' variable in a run
script. Common options are:

- disabling the graphical output:

  append xen_args { sdl="0" }

- configuring a network device:

  append xen_args { vif=\["model=e1000,mac=02:00:00:00:01:01,bridge=xenbr0"\] }

- configuring USB input devices:

  append xen_args { usbdevice=\["mouse","keyboard"\] }

Note: the 'xl' tool requires super-user permissions and interactive
password input can be troublesome in combination with 'expect' and is not
practical for automatic tests. For this reason, the current implementation
assumes that no password input is needed when running 'sudo xl', which can
be achieved by creating a file '/etc/sudoers.d/xl' with the content
'user ALL=(root) NOPASSWD: /usr/sbin/xl'
(where 'user' is the Linux user name).

aec4f0db2d libc: generate nslexer.c,nsparser.c at build stage
The files are generated via flex and bison. Until now, this step was
performed when preparing the libc port. Unfortunately, the generated
files have subtle differences depending on the flex/bison versions
installed in the host. For example, the bison version number appears in
the generated code. This, in turn, breaks the hash mechanism of the

bb52181bc5 menu_view: fix frame dropping after sleep
When idle, menu_view de-schedules timer events to save processing time.
Once reactivated by a dialog update, it computes the passed time and
applies the result to the animator. However, the animation was most likely
started by the update not during the sleep. So the passed time must not
be applied to the animation in this case. Otherwise, many animation steps
are computed at once within a single visible frame.

Furthermore, the patch adjusts the REDRAW_PERIOD to 2, which is a better
value for geometric movements as opposed to mere color-blending effects
where the frame rate does not matter so much.

It also refines the nitpicker-buffer relocation in a way that extends
the buffer but does not shrink it. This lowers the interaction with
nitpicker in situations where the dialog size changes a lot.

b0935ef9b2 VFS: nonblocking interface
The VFS library can be used in single-threaded or multi-threaded
environments and depending on that, signals are handled by the same thread
which uses the VFS library or possibly by a different thread. If a VFS
plugin needs to block to wait for a signal, there is currently no way
which works reliably in both environments.

For this reason, this commit makes the interface of the VFS library
nonblocking, similar to the File_system session interface.

The most important changes are:

- Directories are created and opened with the 'opendir()' function and the
  directory entries are read with the recently introduced 'queue_read()'
  and 'complete_read()' functions.

- Symbolic links are created and opened with the 'openlink()' function and
  the link target is read with the 'queue_read()' and 'complete_read()'
  functions and written with the 'write()' function.

- The 'write()' function does not wait for signals anymore. This can have
  the effect that data written by a VFS library user has not been
  processed by a file system server yet when the library user asks for the
  size of the file or closes it (both done with RPC functions at the file
  system server). For this reason, a user of the VFS library should
  request synchronization before calling 'stat()' or 'close()'. To make
  sure that a file system server has processed all write request packets
  which a client submitted before the synchronization request,
  synchronization is now requested at the file system server with a
  synchronization packet instead of an RPC function. Because of this
  change, the synchronization interface of the VFS library is now split
  into 'queue_sync()' and 'complete_sync()' functions.

6184a27619 init: defer forwarded session requests when needed
This patch changes init's service forwarding such that pending requests
are kept unanswered as long as the requested service is not present
(yet). In dynamic-init scenarios, this is needed in situtions where the
dynamic init is known to eventually provide the service but the internal
subsystem is not ready yet. Previously, a client that attempted to
request a session in this early phase would get a 'Service_denied'
exception. By deferring the forwarding in this situation, the behaviour
becomes deterministic.

If a matching '<service>' exists but there is no matching policy sub
node, the request is answered with 'Service_denied' - as expected.

47dc708887 usb rpi: get rid of local hardware timer
We used a hardware timer locally in the RPI USB driver because a timer
connection was not precise enough to fullfill the host controllers
requirements.

With the modern timer connection interface, however, reading out time at
a connection is microseconds precise and we can remove the local timer.
But we cannot use the same timer connection for doing legacy-interface
stuff like usleep (currently used in LX kit) and modern-interface stuff
like curr_time. Thus, we open two connections for now.

b6efa7f6f9 timer connection: fast initial calibration
The calibration of the interpolation parameters was previously only done
periodically every 500 ms. Together with the fact that the parameters
had to be stable for at least 3 calibration steps to enable
interpolation, it took at least 1.5 seconds after establishing a
connection to get microseconds-precise time values.

This is a problem for some drivers that directly start to poll time.
Thus, the timer connection now does a calibration burst as soon as it
switches to the modern mode (the mode with microseconds precision).
During this phase it does several (currently 9) calibration steps
without a delay inbetween. It is assumed that this is fast enough to not
get interrupted by scheduling. Thus, despite being small, the measured
values should be very stable which is why the burst should in most cases
be sufficient to get the interpolation initialized.

adaad64fbb timer connection: relax factor shifting
When in modern mode (with local time interpolation), the timer
connection used to maximize the left shifting of its
timestamp-to-microseconds factor. The higher the shift the more precise
is the translation from timestamps to microseconds. If the timestamp
values used for determining the best shift were small - i.e.  the delay
between the calibration steps were small - we may got a pretty big
shift.  If we then used the shift with bigger timestamp values - i.e.
called curr_time seldom or raised calibration delays - the big shift
value became a problem. The framework had to scale down all measured
timestamps and time values temporarily to stay operative until the next
calibration step.

Thus, we now raise the shift only that much that the resulting factor
fullfills a given minimum. This keeps it as low as possible according
to the precision requirement. Currently, this requirement is set to 8
meaning that the shifted factor shall be at least 2^8 = 256.

8750e373a0 timer session: add elapsed_us method
As timer sessions are not expected to be microseconds precise (because
of RPC latency and scheduling), the session interface provided only a
method 'elapsed_ms' although the back end of this method in the timer
driver works with microseconds.

However, in some cases it makes sense to have a method 'elapsed_us'. The
values it returns might be milliseconds away from the "real" time but it
allows you to work with delays smaller than a millisecond without
getting a zero delta value.

This commit is motivated by the need for fast bursts of calibration
steps for the time interpolation in the new timer connection.
