On systems with the option `use-keyboxd` enabled in config, option
`--no-keyring` in gpg command line doesn't work. The result of the
pubkey_id function will be the first key in the keybox keyring instead
of the id of pubkey from the depot user.

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remained a tech demo, and Arora has been replaced by Falkon.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
configured. This must be considered when checking for missing servers.

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.

separately. The "iommu" option is now split up into "iommu_intel" and
"iommu_amd" and thereby can be disabled easily if required for one of the CPU
vendors.

- no need to explicitly switch off vga anymore
- use vPID for VMs which improves TLB usage if multiple vCPUs on same
pCPU is used, which happens to happen on Sculpt.
- support for mwait by nova kernel, which is off by default
Issue #5206
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.

for other VMMs beside Virtualbox, e.g. Seoul or potentially arm/vmm. The
webcam model depends on libyuv, which uses stdcxx + full libc, which is not
desired or required for all VMM implementations.
