This was a relic from a time where we dumped the page tables from NOVA
and therefore needed to attach the corresponding dataspaces.

On hotplug, the C++ side of the driver now gets just notified,
without any further detection.
On the C++ side, now specific actions are scheduled explicitly, which will be
executed step by step. New appearing actions will be queued and are
not eligible to run before the former actions of the list are processed.
Fixe #5392
Don't try to decide based on the hardware state, in which mode a
connector is used. If a previous configuration failed, e.g. -ENOSPC,
the detection whether the mirrored framebuffer is in use may fail
and the connectors are reported wrongly as discrete.
During modeset traversal take the appropriate lock to synchronize irq and
user task, which may be de-scheduled by Linux code when invoking contrib
code.
Issue #5377
The driver code may allocate framebuffers which do not fit in the aperture.
Trying to use such framebuffer may lead to only partial visible content
on the screen and the rest either black or garbage.
Instead check for this circumstance and deny to use such framebuffers and
release them, since the user would get an unusable/hard to interpret state.
Additionally, release the vma mappings earlier in order to reduce the likelihood
of such un-mappable framebuffers.
Issue #5377
The changes "intel/display: report connectors w/o modes as off" still
need improvements to detect mode-less connectors in intermediate states.
Until then, don't report connector_status_unknown as connected with
modes.
On capture creation for discrete usage, use the connector values
if display mode does not provide values. For mirror capture ever
report no width_mm/height_mm.
This patch adds the physical screen size as argument to the
Capture::Session::buffer RPC function, which allows drivers to
propagate DPI information to the GUI server. While changing the
the interface, the patch replaces the former use of C++ exceptions
by a result type. The 'Buffer_result' is handled transparently by the
Capture::Connection. The client.h code is now integrated in
connection.h.
Issue #5344
- only mark framebuffer dirty if necessary
-> gives the hardware chance to save longer power
- remove extra timer connection on Genode component side
-> use Linux time primitives
Issue #5339
The use of the Linux-internal SLUB allocator is supported by lx_emul and
drivers may now decide between the Linux implementation or our emulation
of kmem_cache. Drivers for pc and virt already use SLUB, while other
drivers still use the emulation and may be adapted step-by-step incl.
the testing on the devices.
Fixes#5236
Since page tables might need to be allocated during
insert_translation(), Out_of_ram or Out_of_caps exceptions might occur.
Entries that have already been added by insert_translation() must thus be
removed once one of those exceptions occurred.
Fixes#5254
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.
