728ea95857 intel/display: improve mirror/discrete reporting
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.

6f5bcd4446 intel/display: check for mappable framebuffer
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.

8ec2d6a36b intel/display: don't report unknown state as connected
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.

driver/wifi: remove auto_connect attribute
This commit does away with controlling the join-intent via an attribute
but couples it to the existence of a '<network>' node. With this change
all '<network>' nodes within the configuration are always
unconditionally considered for joining.

6d68d3297d capture_session: propagate physical size in 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.

d4e4b8bf60 driver/wifi: rework CTRL interface manager
This commit streamlines the interaction between the Wifi::Manager
and the wpa_supplicant's CTRL interface.

As user-facing changes it alters some default settings and introduces
new features:

* Every configured network now needs to explicitly have its
  'auto_connect' (to be considered an option for joining) attribute
  set to 'true' whereas this was previously the default value if the
  attribute was not set at all.

* The 'log_level' attribute is added and configures the supplicant's
  verbosity. Valid values correspond to levels used by the supplicant
  and are as follows 'excessive', 'msgdump', 'debug', 'info', 'warning'
  and 'error'. The default value is 'error' and configures the least
  amount of verbosity.

* The 'bgscan' attribute may be used to configure the way the
  supplicant performs background-scanning to steer or rather optimize
  roaming decision within the same network. The default value is set
  to 'simple:30:-70:600'. It can be disabled by specifying an empty
  value, e.g. 'bgscan=""'.

* The 'verbose_state' attribute was removed alltogether and similar
  functionality is now coverted by 'verbose' attribute.

Implementation-wise the internals changed significantly and are
outlined in the following paragraphs.

Formerly the interaction between the manager and the supplicant
was handled in an apparent way where the internal state of each
interaction was in plain sight. This made the flow cumbersome to
follow and therefor each interaction is now confined to its own
'Action' object that encapsulates the ping-pong of commands and
responses between the manager and the supplicant. All actions are
processed in an sequential way and thus there is no longer any
need to defer pending actions depending on the interal state of
the current interaction. Configuration changes as well as events
issued by the supplicant where new actions can be created are
handled in this fashion. Of note are both signal-handlers,
'_handle_cmds' and '_handle_events' respectively.

The state report, which provides the information about the current
state of connectivity to a given wireless network, was dealt with
in the same vein and its handling was spread across the manager
implementation. Again, to make it easier to follow, the generation
of the state report is now purely driven by the 'Join_state' object.
This object encapsulates the state of connectivity and is normally
updated by events issued from the supplicant (see '_handle_events').
It is also incorporated when handling command responses (see
'_handle_cmds').

Handling of timed-actions, like scan and signal quality
update requests, was done by setting a timeout at the Timer session
directly and thus only one timed-action could be pending at any time.
This excluded dealing with timed-actions like connected-scanning
and signal quality polling concurrently. This was changed and now
a One_shot_timeout is used to programm each concurrent timed-action.

For implementing the communication channel for the CTRL interface the
manager and supplicant use a shared memory buffer, the Msg_buffer.
Since the CTRL interface for Genode was implemented using C, some
shenanigans were performed to access the memory buffer. Now the
CTRL interface implementation uses C++ and only exports the functions
required by the supplicant as C. This simplifies the usage of the
Msg_buffer and allows for removing the global functions needed for
synchronizing the Msg_buffer access as those are now part of the
object itself via the 'Notify_interface'.

995208585b sculpt: move goa_testbed preset into pc repo

the wrong preset due to the particular order in the build.conf, we move
the preset into the pc repo.

191306531c dde_linux: generate proper KBUILD_MODNAME
This commit remedies the somewhat lazy attempt to address unique names
for drivers where the name is directly derived from KBUILD_MODNAME,

of Linux' build-system. The last part becomes necessary as driver
matching tables may rely on that as has already happend with the
ti-sn65dsi86 driver.

30b39d5fa3 base: generalize the page table allocator and move it to base
The Intel IOMMU page table implementation in the pc platform driver uses

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.
