This patch adds diagnostic messages during the label-policy application,
if no policy for the session label was found or if the domain configured
in the policy node does not exist.
From our observations we can tell that the error should not exceed 4%.
However, there is no reasonable explanation by now why the test results
are less stable on these platforms. We have tried several things that
did not lead to an explanation or improvement:
* changing the timing parameters of the scheduler
* switching off SMP
* double-checking the speed of userland and kernel timers

The test threads previously used a stack size independent from the machine
word width. Qemu was previously configured to provide 64Mb of RAM which isn't
sufficient for x86_64.

Print result error and error tolerance per test result. Use TCL commands
'format' and 'abs'to simplify calculations in the conclusion part of the run
script.

This reverts commit d8b95c263b.
Some clients might want to fiddle with the clients play position
(e.g. the mixer) within 'Audio_out::start()' and we might reset
it to an old value if we do it afterwards.
Fixes#1796.
Since all Audio_out server components loop over the packet stream
queue it is save to reset the tail position to one after the play
position. We have to do this because we do not know exactly when
the play position changes (i.e. the driver has processed the packet)
and we might end up with a tail position before the current play
position.
Issue #1796.
Instead of bailing out if the channel list is incorrect check config
node attributes and default settings first.
Being there also fix flawed LOG messages.
Fixes#1794.
This patch unifies the mechanism of selecting server-side policies and
taking session-routing decisions based on session labels. In both cases,
XML nodes are scored against session labels. The score depends on the
XML attributes 'label' (exact match), 'label_prefix', and
'label_suffix'.
Issue #1766
* Provide paravirtualized block API for accessing the second partition
of the block device that is provided by the ESDHC driver.
* Provide paravirtualized serial API for sending log-output over Genodes
serial port.
* Use the latest Linux suggested in the USB Armory Wiki [1] when on USB Armory
while still using the older vendor Linux when on i.MX53 QSB. I.e.,
provide a device tree through RAM and a rootfs through the paravirtualized
block device when on USB Armory while providing ATAGs and Initrd when on
i.MX53 QSB.
* Switch on the LED on the USB Armory when the VMM catches a VM-exception
and switch it off again when as soon as the exception is handled. This
merely show-cases the ability to instrument the LED for such purposes. In an
ideal world, the LED is switched on as long as we're on the "Secure Side"
and switched off as long as we're not.

Move ADMA2 stuff to extra header and unit. Move ESDHCv2 implementations to
extra unit. Use exceptions instead of error codes. Clean-up documentation.
Ref #1497
The manual termination of multi-block writes via "Stop Transmission" commands
seems to leave the card in a busy state sometimes. This causes errors on
subsequent commands. Thus, we have to synchronize manually with the
card-internal state via "Send State" commands. Additionally, the method
for issuing the manual "Stop Transmission" commands was refined.
Ref #1497
We have to issue a data synchronization barrier after writing a ADMA2
table to ensure that the corresponding write commands were actually
executed before issuing the SD command.
Ref #1497
On i.MX53 QSB, a "Send Op Cond" command during the driver initialization
returns another response value than on the USB Armory. As the check for
this response seems to have no relevance for the driver functionality (Linux
reads the value from MMIO but I can't find a place in the source code where
it is used), we simply remove it.

Previously, it was not necessary to acknowledge an IRQ initially before using
it. However, since the IRQ framework changed lately it is. Adapt to this.
Ref #1497
Notify client initially to enforce a client-side ROM update. Otherwise,
a server-side ROM update between session creation and signal-handler
registration would go unnoticed.
Issue #1788
This patch changes the decorator to always apply stacking-order changes
immediately instead of deferring the re-stacking of the nitpicker views
to the next call of 'update_nitpicker_views'. The deferred application
did not always work when more then one windows changed their stacking
position at once because the cached '_neighbor' values interfered with
each other.
The eager re-stacking should not have negative effects on the user
experience because, in contrast to re-positioning, re-stacking a rare
operation.
This change makes it possible to reuse the generic window decorator
classes in include/decorator/ for decorators of a different structure.
E.g., instead of painting decorations on a single nitpicker session,
each window may paint its decorations into additional window-specific
nitpicker sessions.
In the event where a nitpicker session's quota was depleted by the
allocation of view handles, nitpicker would abort. The patch prevents
the abort by reflecting this condition as an Out_of_metadata exception
to the client. This way, the client can upgrade its session as needed.
The problem was triggered by running the decorator_stress test (changed
to generate 40 windows) with the themed_decorator.
This patch addresses the corner case that the specified neighbor view
is the first view of the view stack. If this is the case when inserting
the view in front of the neighbor (behind == false), the target position
within the view stack must be a null pointer, not the first view.
Because the conditions have become rather complicated, both cases
of 'behind' are handled separately now.
The notion of a channel is shared by the mixer backend as well as the
frontend. To make dealing with reports between those easier move the
Channel definition to a global header.
Issue #1770.
This patch ensures that focus changes performed via the Session::focus
call are made effective the next time, the user is idle. Previously,
focus changes during drag operations were simply discarded.
strip_last_element at Path removes everything after the trailing slash,
which causes lookup failures at the VFS server when opening directories.
Issue #1648
Throw Invalid_name, No_space, and Out_of_node_handles where appropriate.
Catch the new range of errors thrown by at the VFS.
Catch Out_of_node_handles at the VFS, but print a message and re-throw.
Issue #1648
This patch introduces a shortcut for conditional session routes of the
form '<if-arg key="label" value="..."/>'. With this change, the label
can be directly specified as 'label' attribute of an '<any-service>' or
a '<service>' node. The '<if-arg>' mechanism was not documented anyway
and I hope to be able to ultimately remove it.
Currently, when a signal arrives in the main thread, the signal dispatcher is
retrieved and called from the main thread, the dispatcher uses a proxy object
that in turn sends an RPC to the entry point. This becomes a problem when the
entry point destroys the dispatcher object, before the dispatch function has
been called by the main thread. Therefore, the main thread should simply send an
RPC to the entry point upon signal arrival and the dispatching should be handled
solely by the entry point.

* handle interrupts depending on mode of operation
* spelling fixes
* move ATA 'Idendity' struct to ata header
issue #1734
This patch improves the decorator in two ways. First, it enables the
assignment of window colors depending on the window labels. This
configuration can be changed dynamically. Second, it adds the handling
of window controls for closing, maximizing, minimizing windows.
Issue #1689Fixes#1688
This patch supplements the existing focus reports with the new attribute
'active', which indicates recent user activity when set to "yes". This
information is consumed by the clipboard to dynamically adjust its
information-flow policy depending on the user activity.
Issue #1712
This patch moves the formerly internal classes of the report-ROM service
to the public location os/include/report_rom/ so that they can be reused
by other components such as the upcoming clipboard.
