0b247f81f8 wifi: disable scheduled scanning on Intel MVM cards
On MVM only the initial scanning of APs works. If wpa_supplicant changes
from triggered scans to the scheduled-scanning hardware feature no
further scan results are reported. Therefore, we disable the
scheduled-scanning hardware feature until the issue is fixed.

f8337b511b Move Session_label from os to base
Session_label constructor now takes a bare string rather than a
serialized argument buffer.
Replace all instances of previous constructor with 'label_from_args'
function.

558cc8e00c intel_fb_drv: make buffering mandatory
Instead of providing a buffer to the client and blitting from that
to the "real" framebuffer as an option, with this commit we always do so.
Thereby its possible to immediately destroy the old framebuffer used by
hardware when a configuration change is done, and a new framebuffer
is used. This also simplifies the modesetting.
Moreover, this commit fixes an issue when not using the connector reporting.
Until now the initial mode detection of connectors was only done when
the report was created. this is a regression that entered the driver
when upgrading to the recent Linux kernel version.

37fb4309b3 wifi_drv: use relative timeout in poll function
The vanilla 'schedule_timeout()' Linux function expects a relative
timeout value. The first implementation of the wifi_drv, however, used
an absolute timeout value. This mismatch was overlooked when the
lx_kit, which adheres to the vanilla Linux semantics, was incoporated
in the driver.

0106045bad lx_kit: add modular lx_emul backend
The modular lx_kit seperates the required back end functionality of the
Linux emulation environment from the front end. Thereby each driver can
reuse specific parts or supply more suitable implementations by itself.
It is used to reduce the amount of redundant code in each driver.

The lx_kit is split into several layers whose structure is as follows:

The first layer in _repos/dde_linux/src/include/lx_emul_ contains those
header files that provide the structural definitions and function
declarations of the Linux API, e.g. _errno.h_ provides all error code
values. The second layer in _repos/dde_linux/src/include/lx_emul/impl_
contains the implementation of selected functions, e.g. _slab.h_
provides the implementation of 'kmalloc()'. The lx_kit back end API is
the third layer and provides the _Lx::Malloc_ interface
(_repos/dde_linux/src/include/lx_kit/malloc.h_) which is used to
implement 'kmalloc()'. There are several generic implementations of the
lx_kit interfaces that can be used by a driver.

A driver typically includes a 'lx_emul/impl/xyz.h' header once
directly in its lx_emul compilation unit. The lx_kit interface files
are only included in those compilation units that use or implement the
interface. If a driver wants to use a generic implementation it must
add the source file to its source file list. The generic
implementations are located in _repos/dde_linux/src/lx_kit/_.

The modular lx_kit still depends on the private _lx_emul.h_ header file
that is tailored to each driver. Since the lx_kit already contains much
of the declarations and definitions that were originally placed in
these private header files, those files can now ommit a large amount
of code.

fd401bdf53 Thread API cleanup
This patch cleans up the thread API and comes with the following
noteworthy changes:

- Introduced Cpu_session::Weight type that replaces a formerly used
  plain integer value to prevent the accidental mix-up of
  arguments.
- The enum definition of Cpu_session::DEFAULT_WEIGHT moved to
  Cpu_session::Weight::DEFAULT_WEIGHT
- New Thread constructor that takes a 'Env &' as first argument.
  The original constructors are now marked as deprecated. For the
  common use case where the default 'Weight' and 'Affinity' are
  used, a shortcut is provided. In the long term, those two
  constructors should be the only ones to remain.
- The former 'Thread<>' class template has been renamed to
  'Thread_deprecated'.
- The former 'Thread_base' class is now called 'Thread'.
- The new 'name()' accessor returns the thread's name as 'Name'
  object as centrally defined via 'Cpu_session::Name'. It is meant to
  replace the old-fashioned 'name' method that takes a buffer and size
  as arguments.
- Adaptation of the thread test to the new API

511acad507 Consolidate RM service into PD session
This patch integrates three region maps into each PD session to
reduce the session overhead and to simplify the PD creation procedure.
Please refer to the issue cited below for an elaborative discussion.

Note the API change:

With this patch, the semantics of core's RM service have changed. Now,
the service is merely a tool for creating and destroying managed
dataspaces, which are rarely needed. Regular components no longer need a
RM session. For this reason, the corresponding argument for the
'Process' and 'Child' constructors has been removed.

The former interface of the 'Rm_session' is not named 'Region_map'. As a
minor refinement, the 'Fault_type' enum values are now part of the
'Region_map::State' struct.

cda07b7da0 base: simplification of the IPC code
This commit replaces the stateful 'Ipc_client' type with the plain
function 'ipc_call' that takes all the needed state as arguments.
The stateful 'Ipc_server' class is retained but it moved from the public
API to the internal ipc_server.h header. The kernel-specific
implementations were cleaned up and simplified. E.g., the 'wait'
function does no longer exist. The badge and exception code are no
longer carried in the message buffers but are handled in kernel-specific
ways.

d65beb970d dde_linux: KMS-based Intel framebuffer driver (II)
* enable i915 driver from Linux 3.14.5
* tested for generation 5 till 8 GPUs

The driver can be configured at run-time via the config ROM. Every
connector of the graphic card can be configured separately using the
following syntax

  <config>
    <connector name="LVDS-11" width="1280" height="800" enabled="true"/>
  </config>

Also, when enabled within the intel framebuffer driver configuration like
the following

  <config buffered="yes"/>

a simple ram dataspace is propagated to the client and the driver
itselfs copies from that buffer to the framebuffer triggered via refresh
calls. This option is useful to alleviate tearing effects.

The  driver distributes all available connectors of the graphic card and
their supported resolutions via a report. It looks like follows

  <connectors>
    <connector name="LVDS-11" connected="1">
      <mode width="1280" height="800" hz="60"/>
      ...
    </connector>
    ...
  </connectors>

The driver distributes the report only if this is stated within its
configuration, like the following

  <config>
    <report connectors="yes"/>
  </config>

2d869dd15e usb_drv: generate a device list report
The report lists all connected devices and gets updated when devices are
added or removed.

Example report:

<devices>
    <device vendor_id="0x17ef" product_id="0x4816"/>
    <device vendor_id="0x0a5c" product_id="0x217f"/>
    <device vendor_id="0x8087" product_id="0x0020"/>
    <device vendor_id="0x8087" product_id="0x0020"/>
    <device vendor_id="0x1d6b" product_id="0x0002"/>
    <device vendor_id="0x1d6b" product_id="0x0002"/>
</devices>

There is no distinction yet for multiple devices of the same type.

The report is named "devices" and an example policy for 'report_rom' would
look like:

<policy label="vbox -> usb_devices" report="usb_drv -> devices"/>

The report only gets generated if enabled in the 'usb_drv' configuration:

<config>
    <raw>
        <report devices="yes"/>
    </raw>
</config>

dd47129bef nic session: link-state change handling
A Nic::Session client can install a signal handler that is used to
propagate changes of the link-state by calling 'link_state_sigh()'.
The actual link state is queried via 'link_state()'.

The nic-driver interface now provides a Driver_notification callback,
which is used to forward link-state changes from the driver to the
Nic::Session_component.

The following drivers now provide real link state: dde_ipxe, nic_bridge,
and usb_drv. Currently, OpenVPN, Linux nic_drv, and lan9118 do not
support link state and always report link up.
