When having a maximized terminal window, a suspend was causing an
invalid mode change at nitpicker. This triggered a huge resource request
in nitpicker because the RAM-quota check was rendered ineffective by a
wrap-around during unsigned multiplication.

The test reverts the platform drivers' config at the end of the test
to an empty state. However, this state should still contain a default
policy (analogyously to the initial state). Otherwise, the platform
session of the test program will (sometimes) become invalid just before
successfully finishing the test.
The original use cases of the loader have long been covered by the
dynamic init. The only substantial client of the loader remained to be
the qpluginwidget. However, the qpluginwidget was supported only by the
Arora web browser. But the blending of plugins with websites ultimately
remained a tech demo, and Arora has been replaced by Falkon.

When more than one thread are accessing the DRM interface it is not wise
to use global locking, especially when a pthread is executing a batch
buffer and waits for a completion signal in the VFS-plugin. In case the
EP gets stuck in the global lock, no progress is made. Therefore:
* use _drm_mutex only where strictly necessary
* use special _exec_mutex to protect buffer execution (per context)
* print warning when two threads try to execute a buffer in the same
context

Default disabled initialization prevents follow-up errors if one
capability is already enabled on boot, but platform_drv decides to
enable the other one. The PCI spec explicitly states that "Behavior is
undefined if both MSI and MSI-X are enabled simultaneously".

A launched child only becomes present in the runtime when it has been

Using a segment to reserve the AP (application processor) code page does not
work if the region overlaps with other non-memory types, e.g. bender checks
for the overlapping and denies to boot on such machines.
Without bender, the system boots up fine. So, partially remove the nova commit
"Add segment to reserve AP startup page" and instead apply the idea of
Cyberus's version. Place the AP boot code later during boot and save and
restore the memory before/after SMP bootstrap.
Prerequisites for Mesa 24.0.1
* generic:
* add patch to retrieve PCI/Platform information from Genode side of the DRM
interface (in drmGetDevice2)
* add generated 'fourcc' file
* iris:
* report back-end (currently 'i915', 'xe' is unsupported)
* add various I915_CONTEXT_PARAM* and I915_PARAM*
* allocate 'Buffer's starting with ID 1 (0 is invalid)
* enforce 48-bit-address limit on unmap also
* disable I915_EXEC_FENCE_ARRAY array check, because we do not support
sync objects right now and rendering in synchronous
* etnaviv:
* create 'Fenceobj' only *once* for each GPU context
issue #5224
The initial SVM implementation (correctly) just used another standard
x86_64 page table for nested paging. The EPT implementation is for Intel
VMX only. Since we don't know the underlying virtualization technology
at compile time, we need to pick the correct page table implementation
at runtime.
Add add a AMD-compatible HPT page table implementation using the same
base implementation and (more importantly) allocator as the EPT
implementation. Add a Vm_page_table implementation that determines the
used virtualization technology at runtime and internally defers insert
and remove operations to the correct page table implementation.
Issue #5218
To make the x86 page table base implementation compatible with the
function signatures used in hw, make the Intel IOMMU specific arguments
optional:
- Make the `flush` parameter default to false.
- Make the `supported_sizes` parameter default to 1GB + 2MB + 4k.
Issue #5217
The Intel IOMMU page table implementation in the pc platform driver uses
a page table allocator that is adapted from the implementation in the hw
kernel.
Move the allocator to base as a first step to consolidate
implementations, fix an Array constructor and re-add the Allocator
constructor working on addresses instead of tables.
Issue #5217
On hw, `Page_flags` is used throughout architectures. At the same time,
it is used by the Intel IOMMU page table implementation in the pc
platform driver.
Consolidate the definition in base so it is available for all users.

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.
Issue #5113
The SVM implementation did not lend itself to a runtime selection of the
x86 virtualization technology.
Encapsulate functionality in the VMCB class to facilitate adding support
for Intel's VMX.
Issue #5113
The initial algorithm ported to hw seems to be correct in principle,
however it does not work with nested virtualization.
Clean up the code to make the different methods of obtaining the TSC
frequencies more clear, and add warnings if a particular
method has failed although it should be available.

We discovered this relocation, which does nothing, in pre-compiled
libraries. It is easy to implement because it has the same
relocation-type number (0) for all supported ABIs.
Also adjust error message from "Unsupported PLT relocation" to
"Unsupported translation table address format" to not confuse the
relocation type with the translation table type.

During resume the waiting for Cmd::St takes ~2s on a T460p with Intel

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.
With the current RAM setting, opening the inspect window fails on a
display with 4K resolution.
Adjust the inspect window's RAM quota to make it work.

When a new signal arrives, which means a formerly non-pending one,
we should ignore old signal numbers of that context, but only

Fix#5193
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.
Issue #5195
During audio and video playback at a high rate by a VMM, nitpicker on the
boot CPU may interfere with the mixer clients, letting them not finish the
schedule RPC at the mixer in time. Moving nitpicker to the same CPU as
leitzentral mitigates the effect at moment.

At least on x86_64/x86_64/pc/hw|nova, the test used to fail because the net

from 70 to 90 seconds in order to be on the safe side.

This patch addresses corner cases not considered so far. In particular,
it avoids placing the Add/Options tabs of an unscrollable popup under
the panel. This could happen in the presence of many options. The patch
includes the panel height into the calculation to rule out such
situations. It also tightens the scrolling boundaries to the visible
content.

This patch handles intermediate situations where the screen mode may

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

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.

This patch retains the buffer size of the last capture client as mode as

Issue #5174
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.
Fixes#5184.
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.

In the scheduler's implementation preserve the consumed slack-time

activated jobs to the end of the slack queue, insert it as new head.
Thereby, the extreme discrimination of threads with short execution
times and frequent blocking behaviour against long running computations
gets avoided.
