e29485fa59 dde_linux: decouple Lx_kit::Irq and Platform::Device
Follow-up commit to fix the old usb_drv. Under rpi one and the
same irq can be requested several times. Therefore, we've to track
the Irq_connection objects.

e223be32ce dde_linux: decouple Lx_kit::Irq and Platform::Device
The Lx_kit::Irq abstraction of DDE Linux was always using the very first
interrupt of a Platform::Device stored in it. Instead of handing over the
platform device it is much more flexible and sane to hand over the actual
interrupt capability.

5f5ad41ad3 hw: unify irq enumeration for Raspberri Pi
By now, the enumeration of peripheral interrupts on Raspberry Pi 1 was
different in between base-hw kernel and Fiasco.OC. Therefore, hacks were
needed in every driver to request the correct interrupt number dependent
on the kernel. Before reproducing the same in the platform driver for rpi,
we can more easily use the same enumeration with base-hw.

c81af531a3 Turn framebuffer drivers into capture clients
This patch replaces the use of the "Framebuffer" session interface by
the new "Capture" session interface in all framebuffer drivers. Thanks
to this change, those drivers have become mere clients of the nitpicker
GUI server now, and are no longer critical for the liveliness of the GUI
server.

The patch touches the following areas:

- The actual driver components. The new versions of all drivers have
  been tested on the respective hardware. Generally, the drivers
  have become simpler.

- The drivers_interactive packages for various boards. The drivers
  subsystem no longer provides a "Framebuffer" service but needs a
  valid route to the "Capture" service provided by nitpicker.

- The driver manager of Sculpt OS.

- This patch changes the role of the test-framebuffer component from a
  framebuffer client to a capture server so that drivers (capture clients)
  can be directly connected to the test component without the nitpicker
  server.

- Framebuffer driver no longer support the unbuffered mode.

- The fb_bench.run script is no longer very meaningful because it
  interplays solely with nitpicker, not with the driver directly.

- All run scripts for graphical scenarios and the related depot
  archives got adapted to the change.

ef741ef80d Change pixel format to 32 bits per pixel
Until now, Genode's framebuffer session interface was based on the
RGB565 pixel format. This patch changes the pixel format to 32-bit
XRGB where the X part is ignored. It adapts all graphical applications
and device drivers accordingly.

The patch also adjusts the users of the drivers_interactive packages,
assigning 64 MiB RAM and 1500 caps to the drivers subsystem, which is
sufficient for covering high resolutions at 32 bits per pixel and to
accommodate multi-component USB HID input stacks.

5ab1505d43 file system: enhanced file status info
This patch extends the 'File_system::Status',
'File_system::Directory_entry', and the related 'Vfs' types with
the following additional information:

- Distinction between continuous and transactional files (Node_type)
  (issue #3507)
- Readable, writeable, and executable attributes (Node_rwx),
  replacing the former 'mode' bits
  (issue #3030)

The types 'Node_rwx', 'Node_type' are defined twice,
once for the VFS (vfs/types.h) and once for the 'File_system'
session (file_system_session/file_system_session.h).
Similarly, there is a direct correspondance between
'Vfs::Directory_service::Dirent' and 'File_system::Directory_entry'.

This duplication of types follows the existing pattern of keeping the
VFS and file-system session independent from each other.

181c78d482 timeout: use uint64_t for all plain time values
This enforces the use of unsigned 64-bit values for time in the duration type,
the timeout framework, the timer session, the userland timer-drivers, and the
alarm framework on all platforms. The commit also adapts the code that uses
these tools accross all basic repositories (base, base-*, os. gems, libports,
ports, dde_*) to use unsigned 64-bit values for time as well as far as this
does not imply profound modifications.

bbe3ee8dc5 block_session: server-defined payload alignment
This patch replaces the formerly fixed 2 KiB data alignment within the
packet-stream buffer by a server-defined alignment. This has two
benefits.

First, when using block servers that provide small block sizes like 512
bytes, we avoid fragmenting the packet-stream buffer, which occurs when
aligning 512-byte requests at 2 KiB boundaries. This reduces meta data
costs for the packet-stream allocator and also allows fitting more
requests into the buffer.

Second, block drivers with alignment constraints dictated by the
hardware can now pass those constraints to the client, thereby easing
the use of zero-copy DMA directly into the packet stream.

The alignment is determined by the Block::Session_client at construction
time and applied by the Block::Session_client::alloc_packet method.
Block-session clients should always use this method, not the 'alloc_packet'
method of the packet stream (tx source) directly. The latter merely
applies a default alignment of 2 KiB.

At the server side, the alignment is automatically checked by
block/component.h (old API) and block/request_stream.h (new API).

a635873568 VFS: Replace global response handlers with local handlers
Replace the I/O response handler that is passed to the VFS at
construction with an object that is dynamically attached to handles.
This object shall also accept read-ready notifications, and plugins are
encouraged to keep handles awaiting ready-ready notifications separate
from handles that await I/O progress.

Replace the use of handle lists in plugins with handle queues, this
makes the code easier to understand and the ordering of notifications to
the application more explicit.

These changes replace the use of the Post_signal_hook from all VFS
plugins, applications must assume that read-ready and I/O notifications
occur during I/O signal dispatch and use an Io_progress_handler at its
entrypoints to defer response until after signal dispatching.

plugins must instead use lists of "Vfs::Vfs_handle" sub-classes, the
lifetime of which are always managed by the plugin.

aa66b5d62f base: remove dependency from deprecated APIs
This patch adjusts the implementation of the base library and core such
that the code no longer relies on deprecated APIs except for very few
cases, mainly to keep those deprecated APIs in tact for now.

The most prominent changes are:

- Removing the use of base/printf.h

- Removing of the log backend for printf. The 'Console' with the
  format-string parser is still there along with 'snprintf.h' because
  the latter is still used at a few places, most prominently the
  'Connection' classes.

- Removing the notion of a RAM session, which does not exist in
  Genode anymore. Still the types were preserved (by typedefs to
  PD session) to keep up compatibility. But this transition should
  come to an end now.

- Slight rennovation of core's tracing service, e.g., the use of an
  Attached_dataspace as the Argument_buffer.

- Reducing the reliance on global accessors like deprecated_env() or
  core_env(). Still there is a longish way to go to eliminate all such
  calls. A useful pattern (or at least a stop-gap solution) is to
  pass the 'Env' to the individual compilation units via init functions.

- Avoiding the use of the old 'Child_policy::resolve_session_request'
  interface that returned a 'Service' instead of a 'Route'.

there is nobody left to unblock the task and thereby execute the

after transmission was temporarily suspended - because the device/fw

401ba6e7fd Manage socket_fs socket lifetime via handles
Socket_fs sockets are now created each time a 'new_socket' control file
is opened, not each time a 'new_socket' file is read. When a handle on a
'new_socket' file is closed the socket and its socket files are
destroyed. The accept control file on a listening socket reads "1" or
reads nothing to indicate a client connection is queued. Client sockets
are accepted by opening an 'accept_socket' file in the listen socket
directory. This file behaves like the aforementioned 'new_socket' file.

we can selectively adjust them to the new strictness over time - by

eba9c15746 Follow practices suggested by "Effective C++"
The patch adjust the code of the base, base-<kernel>, and os repository.
To adapt existing components to fix violations of the best practices
suggested by "Effective C++" as reported by the -Weffc++ compiler
argument. The changes follow the patterns outlined below:

* A class with virtual functions can no longer publicly inherit base
  classed without a vtable. The inherited object may either be moved
  to a member variable, or inherited privately. The latter would be
  used for classes that inherit 'List::Element' or 'Avl_node'. In order
  to enable the 'List' and 'Avl_tree' to access the meta data, the
  'List' must become a friend.

* Instead of adding a virtual destructor to abstract base classes,
  we inherit the new 'Interface' class, which contains a virtual
  destructor. This way, single-line abstract base classes can stay
  as compact as they are now. The 'Interface' utility resides in
  base/include/util/interface.h.

* With the new warnings enabled, all member variables must be explicitly
  initialized. Basic types may be initialized with '='. All other types
  are initialized with braces '{ ... }' or as class initializers. If
  basic types and non-basic types appear in a row, it is nice to only
  use the brace syntax (also for basic types) and align the braces.

* If a class contains pointers as members, it must now also provide a
  copy constructor and assignment operator. In the most cases, one
  would make them private, effectively disallowing the objects to be
  copied. Unfortunately, this warning cannot be fixed be inheriting
  our existing 'Noncopyable' class (the compiler fails to detect that
  the inheriting class cannot be copied and still gives the error).
  For now, we have to manually add declarations for both the copy
  constructor and assignment operator as private class members. Those
  declarations should be prepended with a comment like this:

        /*
         * Noncopyable
         */
        Thread(Thread const &);
        Thread &operator = (Thread const &);

  In the future, we should revisit these places and try to replace
  the pointers with references. In the presence of at least one
  reference member, the compiler would no longer implicitly generate
  a copy constructor. So we could remove the manual declaration.

6d69f946a8 dde_linux/usb: Do not unset carrier flag in register_netdev
Linux does not do that in register_netdev() either. Some drivers set the
carrier flags on attach and never reenable it (as seen with rndis_host).
Consequently, the usbnet driver refuses to receive data as it checks the
carrier state before enqueuing new SKBs to its receive queue.

Apart from rndis_host, this change was tested with an ax88179_178a
device which worked as expected.

2f32308c0b wifi_drv: use task for sending frames
Until now the client called the Linux code directly through the EP
when sending ethernet frames and was not part of the driver's internal
task scheduling. This will lead to problems if the sending code needs
to grab a lock as those depend on running from within a Lx::Task.
Although this has only happend recently when using 8260 devices, this
is an issue that needs to be fix.

This commit addresses the issue by using a dedicated transmit task
in whose context the Linux code sends the ethernet frame or rather
newly allocated skb.

Fixes #2559.
