0ab49dff3a nitpicker: reflect Handle_registry::Out_of_memory
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.

a1c0c99045 nitpicker: fix corner case in view stack operation
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.

2b429ee84c base: Dispatch server signal in entry point
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.

dce6e14e3e os: generalize Session_label, Session_policy
The utilities in os/session_policy.h used to be tailored for the
matching of session arguments against a server-side policy
configuration. However, the policy-matching part is useful in other
situations, too. This patch removes the tight coupling with the
session-argument parsing (via Arg_string) and the hard-wired use of
'Genode::config()'.

To make the utilities more versatile, the 'Session_label' has become a
'Genode::String' (at the time when we originally introduced the
'Session_label', there was no 'Genode::String'). The parsing of the
session arguments happens in the constructor of this special 'String'.
The constructor of 'Session_policy' now takes a 'Genode::String' as
argument. So it can be used with the 'Session_label' but also with other
'String' types. Furthermore, the implicit use of 'Genode::config()' can
be overridden by explicitly specifying the config node as an argument.

b585583ec7 core: do not destroy in object pool's apply scope
Destroying an object within the scope of a lambda/functor executed
in the object pool's apply function leads potentially to memory corruption.
Within the scope the corresponding object is locked and unlocked when
leaving the scope. Therefore, it is illegal to free the object's memory meanwhile.
This commit eliminates several places in core that destroyed wrongly in
the object pool's scope.

24b1f269be Remove Packet_ref from File_system::Packet_descriptor
The intention of Packet_ref was to allow clients to place opaque
references into the packet descriptor itself, which could be observed on
packet completion. Currently no component in our sources uses this
feature and beyond that it is questionable if it should be used at all:
If the server tampers with the ref the client may easily be confused
into observing an incorrect or invalid context. It seems better to
remove the opaque context from the descriptor and leave the actual
implementation to the client and its needs.

ed52d5a211 Introduce 'spec' subdirectories to outline aspects
Instead of holding SPEC-variable dependent files and directories inline
within the repository structure, move them into 'spec' subdirectories
at the corresponding levels, e.g.:

  repos/base/include/spec
  repos/base/mk/spec
  repos/base/lib/mk/spec
  repos/base/src/core/spec
  ...

Moreover, this commit removes the 'platform' directories. That term was
used in an overloaded sense. All SPEC-relative 'platform' directories are
now named 'spec'. Other files, like for instance those related to the
kernel/architecture specific startup library, where moved from 'platform'
directories to explicit, more meaningful places like e.g.: 'src/lib/startup'.

349c15dfe4 timer test: be more tolerant in periodic test

26524edbf4 alarm: reposition reprogrammed alarms in queue
The alarm library failed to handle the case properly where an already
scheduled alarm gets rescheduled before it triggered. Even though the
attempt to reschedule the alarm (twice insertion into alarm queue) was
detected, this condition resulted in the mere modification of the
alarm's parameters while keeping the alarm's queue position unchanged.
This, in turn, may violate the invariant that all enqueued alarm objects
are strictly ordered by their deadlines. The patch handles the case by
dequeuing the alarm object before reinserting it into the queue at the
right position.

0f05fa6fd4 base: resolve dead lock in weak pointer templates
This commit eliminates the mutual interlaced taking of destruction lock,
list lock and weak pointer locks that could lead to a dead-lock situation
when a lock pointer was tried to construct while a weak object is in
destruction progress.
Now, all weak pointers are invalidated and dequeued at the very
beginning of the weak object's destruction. Moreover, before a weak pointer
gets invalidated during destruction of a weak object, it gets dequeued, and
the list lock is freed again to avoid the former dead-lock.

5d678dba9e core: throw Trace::Out_of_metadata in subjects()
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.

* gpio_drv: imx53/omap4
* input_drv: imx53/dummy
* ps2_drv: x86/pl050
* timer_drv

Now, the Irq_session is requested from Gpio::Session:

From now on we use an asynchronous IRQ interface. To prevent triggering
another GPIO IRQ while currently handling the former one, IRQs must
now by acknowledged explicitly. While here, we also changed the GPIO
session interface regarding IRQ management. The generic GPIO component
now wraps the Irq_session managed by the backend instead of using the
GPIO backend methods directly. A client using the GPIO session may
request the Irq_session_capability by calling
'Gpio::Session::irq_session()' and can use this capability when using
a local Irq_session_client.

0fd53c7fe4 Extract numeric string arguments with the correct signedness
There are lots of places where a numeric argument of an argument string
gets extraced as signed long value and then assigned to an unsigned long
variable. If the value in the string was negative, it would not be
detected as invalid (and replaced by the default value), but become a
positive bogus value.

With this patch, numeric values which are supposed to be unsigned get
extracted with the 'ulong_value()' function, which returns the default
value for negative numbers.

9b7e0ce0a5 part_blk: add GPT support
The GUID partition table (GPT) is primarily used by systems using
(U)EFI and is a replacement for the legacy MBR. For now, the current
implementation is able to address up to 128 GUID partition entries
(GPE).

To enable the GPT support in 'part_blk' it has to be configured
accrodingly:

! <start name="part_blk">
! [...]
!   <config use_gpt="yes">
! [...]
! </start>

If 'part_blk' is not able to find a valid GPT header it falls back
to using the MBR.

Current limitations:

Since no endian conversion takes place it only works on LE platforms
and of all characters in the UTF-16 encoded name field of an entry
only the ones included in the ASCII encoding are printed. It also
ignores all GPE attributes.

db56946ba9 rom_prefetcher: Yield CPU after each request
By blocking on a timeout, we yield the CPU in order to give a

Otherwise, such requests would be deferred until the ROM prefetcher
completes its operation or in the unlikely event that the prefetcher
gets preempted.

Instead of fixing the missing dynamic facilities of the AHCI driver

9a4a0448be hw vea9x4: remove trustzone support
When building Genode for VEA9X4 as micro-hypervisor protected by the ARM
TrustZone hardware we ran into limitations regarding our basic daily
testing routines. The most significant is that, when speaking about RAM
partitioning, the only available options are to configure the whole SRAM
to be secure and the whole DDR-RAM to be non-secure or vice versa. The
SRAM however provides only 32 MB which isn't enough for both a
representative non-secure guest OS or a secure Genode that is still
capable of passing our basic tests. This initiated our decision to
remove the VEA9X4 TrustZone-support.

- The signal test also stresses the case of many managed context in one

This patch fixes a potential race condition that could happen if a

reported to the nitpicker client can be tweaked per domain using the

it is taken as literal boundary. If the value is negative, the size
if deducted by the specified amount from the physical screen area.

This patch introduces a mandatory layer attribute to domains. The layer
ordering is superimposed on the stacking order of the views. The
top-most layer can be assigned to a pointer-managing client. An example
for such a pointer is located at os/src/app/pointer. It replaces the
formerly built-in nitpicker mouse cursor.

The new layering mechanism replaces the former "stay-top" session
argument. So the Nitpicker::Connection no longer takes the stay-top flag
as the first argument.

dbebfd624e nitpicker: Domain configuration
This patch introduces the notion of a "domain" to the nitpicker
configuration concept. Session policies always refer to a domain where
multiple session policies can refer to the same domain. Thereby a domain
provides a way to express the grouping of sessions. This is useful for
applications that open multiple nitpicker sessions (such as Qt5 apps that
use one nitpicker session per window, menu, etc.). We want to assign all
those sessions to a single domain.

The configuration looks as follows:

<config>

  <domain name="default" color="#ffffff"/>
  <policy label="" domain="default"/>

d22cddd1e8 nitpicker: Perform redraw asynchronously
This patch changes nitpicker's way of redrawing. Originally, redraw
operations were triggered immediately by the RPC functions invoked by
clients. In the presence of clients that invoked a large number of those
functions, the server could become overloaded with processing redraw
operations. The new version performs redraw operations out of band with
the RPC functions. Similar to the design of the DOpE GUI server, redraw
operations are processed periodically. The RPC functions merely modify
meta data and track the dirty areas that need to be updated.
Consequently, nitpicker's RPC functions become light-weight operations.

As a nice collateral effect of this patch, nitpicker's internal
structure could be simplified because the drawing backend is no longer
needed by the code that dispatches the RPC interface.

0ed68a56b7 Use signals for delivering input events
This patch changes both the Input::Session interface and the skeleton
for the server-side implementation of this interface
('input/component.h').

The Input::Session interface offers a new 'sigh' function, which can be
called be the client to register a signal handler. The signal handler
gets notified on the arrival of new input. This alleviates the need to
poll for input events at the client side.

The server-side skeleton for implementing input services underwent a
redesign to make it more modular and robust. I.e., there are no
global functions needed at the server side and the event-queue
enable/disable mechanism is implemented at a central place (in the root
component) rather than inside each driver.
