Create a generic interface for x86 virtualization.
Split the VMCB data structure in `Vmcb_buf` to represent the physical
VMCB page and `VMCB` as a control interface.
Issue #5113
So far, the VMCB data structure was generated from it's parts (most
prominently VMCB Control Area and VMCB State Save Area) with the VMCB Control
Area accessed via the Mmio framework, while the VMCB State Save Area
struct used directly defined members.
Unify the VMCB structure and uniformly use the Mmio framework to access
the VMCB. Separate the controlling structure from the VMCB page.

Instead of using one default policy when creating an mmc driver's
configuration, produce some more static policy items to support
boards with more than one card per driver (mnt_reform2).
Both keys are physically the same on available keyboards (with varying
labeling). Unfortunately, PS/2 scancode sets and USB HID spec seem to
differ slightly in their interpretation. Therefore, we keep the
driver-level reporting as is but report both as KEY_PRINT in Sculpt,
which allows to use the key(s) for screenshoter rules most prominently.
Also, unify sculpt/event_filter/pc with sculpt_manager.

The ported i2c_hid driver contains driver code for the "Intel
Tigerlake/Alderlake PCH pinctrl/GPIO" device. Unfortunately, acpica
driver also accesses the same device on Lid open/close via ACPI AML code
of the DSDT table to read out the state of a GPIO pin connected to the
notebook lid. This would fail as I/O memory is handed out only once and
cannot be shared. The workaround disables the region check for the
specified GPIO I/O memory regions and provides both drivers shared
access to the regions.
This is a preliminary workaround. A general solution should separate the
GPIO driver into a component (e.g., platform driver) that regulates
accesses by i2c_hid and acpica.

During audio and video playback at a high rate by a VMM, nitpicker on the

This patch addresses corner cases not considered so far. In particular,
it avoids placing the Add/Options tabs of an unscrollable popup under

This commit adds missing routes to I2c for the framebuffer driver of the

Commit "sculpt: safeguard the offering of suspend/resume" was too lax

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

This patch enhances the sculpt manager to drive the system state

resume cycles.
The new Power options can be found in the System menu. The suspend

Note that the USB controller is hard restarted when resuming from

with visual noise on the screen. Instead, use the already in use ggtt object

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.

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.

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.

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

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.

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

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

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

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 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

known/managed features (phone hardware), and options that can be
toggled at runtime.
With common patterns for managing drivers in place now, this commit
