This patch handles intermediate situations where the screen mode may
become 1 x 1 (absence of any capture clients). In this case, the
decoration of a maximized window would legitimately exceed the screen
boundary.

The blanking state is evaluated by the intel_fb driver, which will switch
off all connectors. When done, the intel_fb driver will exit and the
sculpt_manager will continue with the next step, stopping all drivers.

This commit adds missing routes to I2c for the framebuffer driver of the
MNT Reform. If build for this concrete board the Board_info::Soc variable
within the sculpt_manager is initialized according to the properties of
this device. The `update_soc` routine is called in the initialization of
the sculpt_manager, otherwise it won't be called at all, if no PCI devices
changes are detected. Missing driver binaries and device-tree-binaries are
add to the run-script.

A network card can be provided by PCI, and the SoC as well. Therefore,
add an additional state variable in the Board_info::Soc, and check it
appropriatedly.

Commit "sculpt: safeguard the offering of suspend/resume" was too lax
about the detection of acpi support. In situations where acpi support
is selected but not yet installed, the menu would offer the features
already. This patch restricts the condition such that acpi support must
be running, not merely selected.
Issue #5174
This patch retains the buffer size of the last capture client as mode as
long as no capture client exists. This avoids intermediate mode changes

The USB host controller gets restarted during the suspend-resume cycle.
Hence, don't offer suspend while any USB storage device is in use, in
particular when deploying Sculpt from a USB stick.
Suspend/resume is not supposed to work with any framebuffer driver other
than intel_fb. Therefore, offer the suspend feature only when using intel_fb.
Issue #5174
The automatic restart of intel_fb got lost during the transition from
the driver manager. This commit restores the heartbeat monitoring of
this driver.
Issue #5174
This patch enhances the sculpt manager to drive the system state
and manage the lifecycle of driver components during suspend-
resume cycles.
The new Power options can be found in the System menu. The suspend
and power-off controls are presented only when the acpi-support
option is activated.
Note that the USB controller is hard restarted when resuming from
suspend. Hence, all components that depend on USB are restarted
implicitely.

on display client close (intel_fb). The former code constructed a
temporary object on the stack, which sets up the scratch pages for the
closed client. However, the scratch page backing store (dma_buffer) gets
freed on destruction of the temporary stack object, which leads to DMA faults
with visual noise on the screen. Instead, use the already in use ggtt object
and add the scratch pages explicitly.

This commits updates the contrib sources to version 8.7.1.
This version requires more random entropy as it queries OpenSSL
about the current random state and will bail if it is not sufficient.
Doubling the content of the '<inline>' VFS plugin as used in static
configurations seems satisfactory.
Furthermore DNS resolving needs a configured '<pipe>' plugin to work
properly.

Instead of returning an invalid capability whenever an interface is
requested that does not exist, create a disconnected interface component.
It is also possible that a client requests an interface that got removed
at the same time. When an invalid capability gets returned, a client
can stumble about invoking it.
Moreover, this commit marks either invalid interface or device components
as disconnected objects to optimize their handling.

Issue #5174.
This commit introduces the means to configure the framebuffer memory
used by the driver for sizing its buffers.
Originally the avail memory was derived from the avail ram in the PD
session, which roughly corresponds to configured RAM quota.
However, since it is only used in a virtual capacity, we can decouple
it from the actual memory and set to a value that accommodates larger
framebuffer resolutions like 3840x2160. If the configured RAM quota
is not enough to satisfy an allocation request the client will issue
a resource request.

Commit 'wifi_drv: re-arm scan timer when enabled again' allowed for
re-arming the scan timer but still uses the old timer value the first

arm the scan timer afterwards.

The audio launcher configures the 'bsd_audio_drv' component for normal
use where the micrphone selection should work on most Thinkpads.
The mixer launcher configures the 'record_play_mixer' component for
use with the 'audio' launcher and provides also examplary rules for
vbox6 launchers.
This commit prefixes the Play sessions of the audio driver so that
these can be matched differently in the 'record_play_mixer' config.
The same could be archived with re-labling but naming the sessions
differently at the source prevents accidental mis-configuration.

Executing a clflush operation on MMIO memory freezes embedded

Since "sculpt: adjust nitpicker priority", the nitpicker GUI server no
longer runs at the highest priority, yet the runtime_view of the
leitzentrale UI continued to operate at the highest priority.
On slower machines, this results in a visible interference of the CPU-
heavy rendering of the runtime_view with the (now) lower-prioritized
nitpicker, in particular laggy pointer movements.
This commit subordinates the leitzentrale components below the priority
of nitpicker to prevent this interference.
It also simplifies the priority scheme at the static system init: The
timer has the highest priority whereas all other components use the
priority band -1.

The hard resource limit introduced by "sculpt: upper limit for automatic

Allow tweaking the driver selection using the manager config:
- The new attribute 'ps2="no"' suppresses the selection of the PS/2 driver.
- The new attribute 'intel_gpu="no"'suppresses the selection of the
Intel GPU and fb drivers, letting Sculpt fall back to VESA or boot-fb.
Note that the dynamic change of those attributes is handled in principle
but not advisable. E.g., disabling the intel driver after startup leaves
the hardware in a state that the VESA driver cannot cope with. However,
when statically defining the attributes in sculpt/manager/default, it is
now possible to build an image that uses VESA on an intel machine.

The nightly Qemu tests that don't use KVM require more time for completing the

Furthermore, on FOC, the cap quota was insufficient.

The existing allocation scheme of window IDs has the unwelcome effect
that a re-appearing window would not always result in a visible change
of the window list. In such cases, the layouter and decorator would not
be prompted to do their job. This effect could be observered with the
multi-dialog version of menu view in Sculpt OS when manually enforcing
the restart of the runtime_view. Sometimes the panel would not re-appear
after the restart.
This patch changes the allocation of window ID such that new windows get
fresh IDs instead of reusing an ID of a recently disappeared window.

Rarely. it might happen that events got received shortly before the complete

This substantially slims down the test in order to reduce the number nightly

and benchmarks) are only run on Linux. The synchronous access, snapshot
management, rekeying, and resizing tests were removed.

This patch replaces the former use of one menu-view component per dialog

The font pointers cached in labels can become dangling when the style
database is updated, as happens when changing the font size dynamically.
This patch orderly updates the cached pointers before removing

This patch equips the menu-view component with the ability to present
more than one dialog at a time. The dialogs must be declared in the
<config> node as follows.
<config>
...
<dialog name="settings"/>
</config
For each dialog, menu view requests a dedicated ROM session labeled after
the dialog name. The corresponding GUI session is also labeled as such.
Note that only one hover report is generated responding to all dialogs.
The hover report can be correlated with the hovered dialog by inspecting
the the 'name' attribute of the hover report's <dialog> sub node.
The former global config attributes 'xpos', 'ypos', 'width', 'height',
'opaque', and 'background' have become attributes of the <dialog> node.

The new VFS OSS plugin utilizes the Record and Play session. For the

its limitations.
In contrast to the old plugin it is possible to force a client to

fragments, e.g. VBox, where raising the minimal fragment size is
beneficial.

This patch lays the selection of the used storage target into the hands
of the config/manager file. By default, Sculpt selects the target by its
built-in heuristics, probing for a Sculpt partition. However, by
specifying a <target> node, one can explicitly select a storage target.
E.g., for using the 2nd partition of the SATA disk connected to port 1
of the AHCI controller, one can now specify:
<target driver="ahci" port="1" partition="2"/>
For selecting the ram_fs as target:
<target driver="ram_fs"/>
The latter case is particularly useful for custom Sculpt scenarios
deployed entirely from RAM. For such scenarios, add two lines to
your .sculpt file:
ram_fs: depot
manager: use_ram_fs
The first line configures the ram_fs such that the depot is mounted
as a tar archive. The second line configures the sculpt manager to
select the ram_fs as storage target. You can find this feature
exemplified in default-linux.sculpt scenario.
build/x86_64$ make run/sculpt_test KERNEL=linux BOARD=linux
It is worth noting that the configuration can be changed at runtime.
This allows for switching between different storage targets on the fly.

All errors (as in the legacy version) are now propagated as WRITE_ERR_IO
(see Lxip_vfs_file_handle::write), which ultimately will lead to EPIPE

that partial writes are not supported for blocking sockets in libc, also
libc will not try a second time in case not all data has been written.

The IP stack checks "user" pointer access, for example, for iov's using
'access_ok' which in turn calls '__access_ok'. The function checks if the
pointer is below TASK_SIZE_MAX, which is usually a big value on 64 bit
systems, but 3GB on 32 bit systems. Because the IP stack is mostly used with
Genode's libc, where pointers on some kernels (base-linux) can be >3GB and we
don't want to make an additional copy of each buffer/iov interacting with the
IP stack, we short circuit the function
issue #5165
This patch replaces the dynamic use of Attached_rom_dataspace by a
new Rom_handler utility, which implicitly covers the initial import of
content (safely using 'local_submit'), the registration of the signal
handler, passes the Xml_node to the handler function (no need to
manually call 'update'), and provides scoped access to the content via a
'with_xml' method. The latter reinforces a programming style that does
not need to copy Xml_node objects.

This patch removes the remains of the original block-device discovery as
done by the former driver manager. Block sessions are now always

Issue #5150
This patch harmonizes the driver management between the sculpt manager
and the phone manager by hosting the individual drivers in a new
'Drivers' class with a narrow interface towards 'Sculpt::Main'. The
patch also introduces a clean separation of the 'Board_info' between
features detected at runtime (on PC hardware), statically
known/managed features (phone hardware), and options that can be
toggled at runtime.
With common patterns for managing drivers in place now, this commit
also moves the former runtime/wifi_drv.cc and runtime/nic_drv.cc
code to driver/wifi.h and driver/nic.h. The _drv suffix of the wifi
and nic driver components have been dropped.

As the NVMe driver was the last remaining driver controlled by the
driver manager, this patch removes the 'drivers -> dynamic' subsystem
along with the driver manager from sculpt/drivers/pc.
Issue #5150
This patch moves the AHCI driver from the 'drivers -> dynamic'
subsystem to the runtime, managed by the sculpt_manager. One
implication of this change is the new need to supplement a device
port number to the 'Storage_target', in addition to the existing
label and partition. Previously, each block device was addressed by
merely a label specified for a parent session. The meanings of the
'Storage_target' elements are now as follows.
- The label corresponds to the driver component providing the storage.
- The port is used as block-session label when opening the session
at the driver.
- The partition(s) denote the partition information contained in
the block session.
Components operating as clients of the AHCI driver (e.g., a file system)
refer to their storage target as <label>-<port>.<partition> when a port
is defined (for AHCI). For drivers w/o ports, like USB storage where
each USB-block driver correponds to only one device, the storage target
is denoted as <label>.<partition>. When no partition table is present,
the '.<partition>' part is omitted.
Issue #5150
This commit moves the USB and USB HID driver from the drivers subsystem

By moving the event_filter and the numlock_remap_rom from the drivers

Adds a new command attribute "uninitialized_data" to the Tresor Tester
configuration. If a <request op="read"> command has this attribute set to "yes"

Note, that a command that has "uninitialized_data" set to "yes" cannot have the
attribute "salt".

Snapshots must only be removed when securing the superblock. Otherwise, the
last secured superblock might get corrupted. The Free Tree allocation algorithm
would not consider the deleted snapshots anymore although they are still active
in the secured superblock and re-use their blocks. This would render the tresor
container unusable if the superblock with the deleted snapshots is not secured
in the end (driver crash, power down, ...).
Ref #5077
Superblock_control::Initialize used to decode a read superblock before checking

Ref #5077
Instead of iterating over all superblocks and checking each valid one,
check only the one whose hash matches the hash stored in the trust anchor.
I.e., the last one that was secured to the trust anchor. We must assume that
the other superblocks were corrupted in the meantime by operating the Tresor
container and, anyway, these Superblocks are not used anymore.

* differentiates request types that where merged formerly per module;

* Superblock_control::Write_vbas
* Superblock_control::Rekey
* Superblock_control::Initialize

each holding only the state and functionality that is required for exactly
that request
* removes all classes of the Tresor module framework and adapts all
Tresor- and File-Vault- related libs, apps, and tests accordingly
* the former "channel" state is merged into the new request types, meaning, a
request manages no longer only the "call" to a functionality but
also the execution of that functionality; every request has a lifetime
equal to the "call" and an execute method to be driven forward
* state that is used by a request but has a longer lifetime (e.g. VFS file
handles in Tresor::Crypto) is managed by the top level
of the user and handed over via the execute arguments; however, the
synchronization of multiple requests on this state is done by the module
(e.g. Tresor::Crypto)
* requests are now driven explicitly as first argument of the (overloaded)
execute method of their module; the module can, however, stall a request
by returning false without doing anything (used for synchronization on
resources)
* introduces Request_helper, Generated_request and Generatable_request in the
Tresor namespace in order to avoid the redundancy of sub-request generation
and execution
* moves access to Client-Data pointers up to Tresor::Virtual_block_device in
order to simplify Tresor::Block_io and Tresor::Crypto
* removes Tresor::Client_data and introduces pure interface
Client_data_interface in order to remove Tresor::Client_data and
move management of Client Data to the top level of a Tresor user
* introduces pure interface Crypto_files_interface in order to move management
of Crypto files to the top level of a Tresor user
* moves management of Block-IO and Trust-Anchor files to the top level of a
Tresor user
* adapts all execute methods, so, that they return the progress state
instead of modifying a reference argument
* removes Tresor::Request_and Tresor:Request and instead implements
scheduling at the top level of the Tresor user
* the Tresor Tester uses a list as schedule that holds Command objects; this
list ensures, that commands are started in the order of configuration
the Command type is a merge of the state of all possible commands that can
be configured at the Tresor Tester; the actual Tresor requests (if any) are
then allocated on-demand only
* the Tresor VFS plugin does not use a dynamic data structure for scheduling;
the plugin has 5 members that each reflect a distinct type of operation:
* initialize operation
* deinitialize operation
* data operation
* extend operation
* rekey operation
consequently, of each type, there can be only one operation in-flight at a
time; at the user front-end each operation (except "initialize") can be
controlled through a dedicated VFS file; for each of these files, the VFS
expects only one handle to be open at a time and only one file operation
(read, write, sync) active at a time; once an operation gets started it is
finished without preemtion (except of the interleaving at rekey and
extend); when multiple operations are waiting to be started the plugin
follows a static priority scheme:
init op > deinit op > data op > extend op > rekey op
there are some operation-specific details
* the initialize operation is started only by the plugin itself on startup
and will be driven as side effect by subsequent user calls to file
operations
* the data file is the only contiguous file in the front end and the file
operations work as on usual data files
* the other 3 files are transactional files and the user is expected to
follow this scheme when operating on them
1) stat (to determine file size)
2) seek to offset 0
3) read entire file once (this will be queued until there is no operation
of this type pending anymore and return the last result:
"none" | "failed" | "succeeded"; used primarily for synchronization)
4) write operation parameters (this returns immediately and marks the
operation as "requested")
5) read entire file once (the same as above but this time in order to
determine the operation result)
* the rekey op and deinitialize op are requested by writing "true"
* the extend op is requested by writing "tree=[TREE], blocks=[BLOCKS]"
where TREE is either "vbd" or "ft" and BLOCKS is the number of physical
4K blocks by which the physical range of the tresor container expands
(the physical range always starts at block address 0 and is always
expanded upwards)
* replaces the former <trust-anchor op="initialize"> command at the Tresor
Tester with <initialize-trust-achor> as there are no other trust anchor
operations that can be requested through the Tester config anyway
* removes the "sync" attribute from all commands at the Tresor Tester except
from <request op="rekey">, <request "extend_ft">, <request op="extend_vbd">;
as the Tester controls scheduling now, requests are generally synchronous;
at the rekeying and extension commands, the "sync" attribute determines
wether subsequent commands are interleaved with the execution of these
commands (if possible)
* removes "debug" config attribute from Tresor VFS plugin and reworks "verbose"
attribute to generate more sensible output
* removes NONCOPYABLE macro and instead uses Genode::Noncopyable and in-place
Constructors deletion
* introduces types Attr and Execute_attr where a constructor or execute method
have many arguments in order to raise readability
* renames the "hashsum" file that is provided by the Tresor Trust-Anchor VFS
plugin to "hash" in order to become conformant with the wording in the Tresor
lib
* makes the VFS Tresor test an automated test by merging in the functionality
of vfs_tresor_init.run and removing the interactive front end; removes
vfs_tresor_init.run as it is not needed anymore; adds consideration for
autopilot file structure in the Test and adds it to autopilot.list
* removes all snapshot controls and the progress files for rekeying and
extending from the Tresor VFS plugin; both functionalities were tested
only rudimentary by the VFS Tresor test and are not supported with the only
real user, the File Vault
* use /* .. */ instead of // ..
* use (..) instead of { .. } in init lists
Ref #5148
The virtual block device module used to hand over the wrong VBA as
parameter "rekeying VBA" to the Free Tree when allocating PBAs for data
access during rekeying. In certain constellations, this caused the Free
Tree to alloc PBAs that were still in use. The Free Tree PBA selection
algorithm, however, is just fine. When fixing the call parameter, it works
as desired. This re-enables the async rekeying test.

Ref #5062
During one of the many re-factorization steps that were applied to the Tresor
library and its predecessor, the CBE library, one of the main features of the
project, the integrity check, accidentally received a grave regression. The
most recent version of the Tresor still used to check all hashes of meta-data
blocks but ignored the hashes of the actual data blocks.
With this commit, the hashes of all but yet uninitialized data blocks get
checked. The reason for ignoring uninitialized blocks is that they are not
actually read from disc but simply generated as an all-zeros block in the
driver in order to prevent having to initialize them all to zero in
Tresor-Init. That said, the integrity of these blocks cannot be compomised.
The according hashes in the meta data remain unset until the data block gets
written for the first time.

This commit rewrites the tool for the most recent Tresor version and adds an

* Make command pool a proper module
* The command pool used to be kind of a module but it was driven via custom
tresor-tester specific code. Now, it becomes a proper module that
is driven by the module framework instead.
* Move the code for creating and handling the module-execution progress flag
into Module_composition::execute_modules as the function is always used with
this code surrounding it.
* Reorganize files, remove deprecated files
* A new class Module_channel is introduced in the module framework and all
channel classes inherit from it. With that class in place, the formerly
module-specific implementations of the following methods are replaced by
new generic implementations in the Module framework:
* ready_to_submit_request
* submit_request
* _peek_completed_request
* _drop_completed_request
* _peek_generated_request
* _drop_generated_request
* generated_request_complete
* Module requests are now held for the duration of their lifetime at the
module they originate from and not, like before, at their target module. As
a result, modules can generate new requests inline (without having to wait
for the target module), making code much simpler to read, reducing the amount
of channel state, and allowing for non-copyable request types.
* Introduce a sub-state-machine for securing a superblock in the
superblock_control module in order to reduce redundancy.
* Some modules, like free_tree, were completely re-designed in order to make
them more readable.
* Replace all conditional exceptions by using the macros in
tresor/assertion.h .
* Move methods that are used in multiple modules but that were implemented
redundantly in each module to tresor/types.h.
* Remove verbosity node and all that was related to it from tresor tester
config as the targeted verbosity can be achieved with the
VERBOSE_MODULE_COMMUNICATION flag in tresor/verbosity.h .
* Extract the aspect of translating the byte-granular I/O-requests to
tresor-block requests from the tresor VFS-plugin and move it to a new module
called splitter.
* Rename the files and interface of the hashing back-end to not reflect the used
hashing algorithm/config anymore, while at the same time making the hashing
interface strict regarding the used types.
* Introduce the NONCOPYABLE macro that makes marking a class noncopyable short
and clear.
* Replace the former tresor/vfs_utilities.h/.cc with a new tresor/file.h
that contains the classes Read_write_file and Write_only_file. These classes
significantly simplify the modules crypto, block_io, and trust_anchor by
moving the details of file access to a sub-state machine.
* The former, rather trivial block allocator module is replaced by a normal
object of type Pba_allocator that must be provided by the client of the
Sb_initializer (reference in the Sb_initializer_request).

tresor: read uninitialized vbas as all zeroes
Virtual addresses in a Tresor container that were not yet written by the user
should always return a data block that is all-zeroes. This was the concept
right from the beginning of the project. However, somehow this aspect either
never got implement or got lost along the way.
Some context for understanding the commit: The Tresor doesn't initialize the
payload data blocks of a container when creating a new container as this would
be rather expensive. Instead, it marks the leaf metadata nodes of the
virtual-block-device tree (those that reference the payload data blocks in
physical address space) with generation 0.
Now, this commit ensures that, whenever the virtual-block-device module reads
such a generation-0 leaf, instead of asking the block_io and crypto to deliver
data from disc, it directly provides the user with 4K of zeroes.
Ref #5062
The order of execution inside the Tresor lib slightly changed compared to the
previous CBE lib. AFAICT, this is nothing to worry about and related to the
now cleaner structuring. However, it can produce higher peak requirements
regarding the allocation pool in the Free Tree. Therefor, this commit extends
the dimensions of the Free Tree used in the test.

* Implement requests "create snapshot" and "discard snapshot" in tresor lib.
* Adapt tresor tester in order to test the new feature.
* Remove temporary code from tresor tester that skipped such requests with
the hint that they were not supported yet.
* Add mandatory "id" attribute to <request op="create_snapshot"/> and
<request op="discard_snapshot"/> tag. A "discard snapshot" command always
refers to the snapshot created by the "create snapshot" command with the
same "id" value.
* Clean-up command pool a bit.
Fix#4971
The re-keying state machine in the VBD module would use block data of the wrong
block for the hash update of an inner node in a certain circumstance.
On re-keying, the VBD iterates for a given VBA over all snapshots, beginning
with the newest and re-keys the VBA in each of the snapshots. At each snapshot
it therefore loads the branch of the VBA top-down, and then updates the branch
bottom-up. However, if loading a certain level of the branch of a certain
snapshot runs into the same physical block as with the last snapshot on this
level, the algorithm turns around and updates the branch from this point
upwards instead of going further down the whole way to the leaf. This is
because everything below this point has already been re-keyed in the course of
a newer snapshot.
The case where this turning around is not right above the leaf (i.e., the first
shared physical block is a metadata block) that's were the bug was located. In
this situation, we have to re-encode the highest shared metadata block into a
buffer again before starting to update. The update code acts as if the
mentioned block was just written back (which is true when going down all the
way to the leaf before updating) and consequently is present in the encoded
buffer.
Ref #4971
Until now, it was possible to use bad Free-Tree/VBD configurations with the
<initialize/> command. The tresor tester didn't complaining about it but the
tresor lib crashed or, worse, corrupted the tresor container. Now, the tresor
tester checks things, like for instance, that "nr_of_children" must be a power
of 2.
Ref #4971
The Superblock Control module now issues a snapshot garbage collection on each
incoming request. In return for that, the commit removes all calls to the
garbage collection from other modules.
Ref #4971
The Virtual Block Device module used to create a local copy of the Snapshots
array respectively Snapshot root it received with an incoming request. After
finishing the VBD operation on the copy, the source module of the request
used to back-copy the resulting Snapshot array resp. Snapshot root. This is
not only less efficient than referencing but also allowed a bug to sneak into
the new C++ implementation.
In contrast to the old Ada/SPARK implementation (CBE), the new design doesn't
allow for global objects that can be accessed by any module without receiving a
reference in a module request. Therefore, the Free Tree module has to receive a
reference to a Snapshots array with each request in order to be able to use it.
In our case, these requests are allocations for a "Write" operation from the
VBD. However, the VBD itself receives only the one Snapshot required for
writing and therefore causes the Free Tree to make bad decisions on whether or
not a block can be re-allocated or not.
With this commit, the VBD always receive a reference to the whole Snapshots
array and also propagates it this way to the Free Tree.

A bunch of transmit requests received by the Uplink server (nic_router)
are currently added one by one to the ring buffer and every time the hardware
is notified to process each single request.
Instead, add as many as possible transmit requests in the ring buffer of
the hardware and when done trigger the hardware to process the ring.
Additionally, don't receive an "processed" TX IRQ for each element in the
ring, which causes high CPU load.
With this commit the TX IRQs in the ipxe driver for a

This patch was back ported from upstream Mesa and generalizes the memory
management of buffer objects used by the binder. Before this patch the
binder was treated as a special case where buffer objects were allocated
with a simple "next block or wrap" allocator. With this commit the
binder now uses the vm_heap allocators as done by all other buffer
allocations which leads to issues with reference counting and object
destruction being resolved.
Original commit message:
We're moving towards a path where all contexts share the same virtual
memory - because this will make implementing vm_bind much easier - ,
and to achieve that we need to rework the binder memzone. As it is,
different contexts will choose overlapping addresses. So in this patch
we adjust the Binder to be 1GB - per Ken's suggestion - and use a real
vma_heap for it. As a bonus the code gets simpler since it just reuses
the same pattern we already have for the other memzones.
This patch contains the mobile variant of Sculpt OS, which evolved

not denote quota but time left for the current schedule. The boolean
variable `_head_claims` gets removed at all. It duplicated the state of
whether a current share ist set, and whether it has so-called claim time
left.

The classes Genode::Mmio, Genode::Register_set, Genode::Attached_mmio, and
Platform::Device::Mmio now receive a template parameter 'size_t SIZE'. In each
type that derives from one of these classes, it is now statically checked that
the range of each Genode::Register::Register- and
Genode::Register_set::Register_array-deriving sub-type is within [0..SIZE).
That said, SIZE is the minimum size of the memory region provided to the above
mentioned Mmio classes in order to avoid page faults or memory corruption when
accessing the registers and register arrays declared inside.
Note, that the range end of a register array is not the end of the last item
but the end of integer access that is used for accessing the last bit in the
last item.
The constructors of Genode::Mmio, Genode::Attached_mmio, and
Platform::Device::Mmio now receive an argument 'Byte_range_ptr range' that is
expected to be the range of the backing memory region. In each type that derives
from on of these classes, it is now dynamically checked that 'range.num_bytes
>= SIZE', thereby implementing the above mention protection against page faults
and memory corruption.
The rest of the commit adapts the code throughout the Genode Labs repositories
regarding the changes. Note that for that code inside Core, the commits mostly
uses a simplified approach by constructing MMIO objects with range
[base..base+SIZE) and not with a mapping- or specification-related range size.
This should be fixed in the future.
Furthermore, there are types that derive from an MMIO class but don't declare
any registers or register arrays (especially with Platform::Device::Mmio). In
this case SIZE is set to 0. This way, the parameters must be actively corrected
by someone who later wants to add registers or register arrays, plus the places
can be easily found by grep'ing for Mmio<0>.

produce the following logging diagnostics:
```
GIM: HyperV: Guest indicates a fatal condition! P0=0xe2 P1=0x0 P2=0x0 P3=0x0 P4=0x0
GIMHv: BugCheck e2 {0, 0, 0, 0}

Fixes#5099
The libc's internal calculation of the tv_sec and tv_nsec fields must be
based on the same ms value. Otherwise, tv_sec is not always immediately
incremented whenever tv_nsec wraps. For applications, this inconsistency
can result in observed jumps in time.
Fixes#5098
Functions registered with 'module_init' (i.e., '__define_initcalls'),
'OF_DECLARE', and 'DECLARE_PCI_FIXUP_CLASS_FINAL' used to be static
constructors and had be explicitly registered using
'exec_static_constructors' before executing any Linux code.
With this commit we remove the constructor attributes from these
functions and create a global function pointer in the form of
__initptr_<name>_<id>_<counter>_<line number of macro>
'import-lx_emul_common.inc' will collect these '__initptr' symbols after
the compile step and generate a 'lx_emul_register_initcalls' function
that executes the functions pointed to. This step is now automatically
performed in 'lx_emul_start_kernel'. This way a call to
'exec_static_constructors' can be omitted in case there are no other
constructors in place.
