813f4d976b lxip: allocate skb with properly aligned IP header
Comment in Linux sources:

  Since an ethernet header is 14 bytes network drivers often end up with
  the IP header at an unaligned offset. The IP header can be aligned by
  shifting the start of the packet by 2 bytes. Drivers should do this
  with:

  skb_reserve(skb, NET_IP_ALIGN);

This is ensured when using netdev_alloc_skb_ip_align().

462bff5aef dde_linux: test subdevice id for device matching
As linux drivers may distinguish device configuration by pci subdevice id in
addition to the pci device id, the former must also be used for finding the
matching entry. Otherwise, e.g., the iwlwifi driver might load the wrong
firmware.

Side note: Add break statement to save superfluous iterations after
match was identified.

dc8c899c1d Streamline platform-device API on ARM
This API rework eases the access to memory-mapped I/O registers and
interrupts when using the platform driver. It introduces the notions of

- Platform::Device       - one device obtained from a platform session
- Platform::Device::Mmio - locally-mapped MMIO registers of a device
- Platform::Device::Irq  - interface for receiving device interrupts

The patch touches several drivers. Some drivers would require a
significant structural change to adopt the new API (e.g., net/virtio,
dde_linux drivers, imx gpio). In these cases, the patch adds
compatibility shims meant to be temporary. In other cases (e.g., imx
i2c), the adaptation was simple enough to carry through.

0339318572 platform_session: cache arg for alloc_dma_buffer
This patch extends the 'Platform_session::alloc_dma_buffer' interface
with a 'Cache' argument that corresponds to the argument accepted by
'Ram_allocator::alloc', which is used by the platform driver under the
hood.

Since the x86 platform driver used to be hardwired to allocate DMA
buffers as UNCACHED, I adjusted all drivers by specifying the UNCACHED
argument. Right now, this is needed as a hint for core to steer the
allocation of I/O page tables. Once we eliminate the need for such hints
(by introducing an explicit 'Region_map::attach_dma' operation), we can
revisit the drivers individually because cached DMA buffers should
generally be fine on the x86 architecture.

23620942bf usb_net: allow calling netif_stop_queue dummy
When the usb_net_drv was introduced in ports/run/netperf.inc, the
netperf_lxip_usb test on x86_64/hw/pc triggered the calling of the
netif_stop_queue dummy at
contrib/<DDE_LINUX>/src/drivers/usb_net/drivers/net/usb/usbnet.c:1464. As
netif_start_queue was also a dummy and allowed to be called, we tried allowing
calls to the netif_stop_queue dummy as well which fixed the
netperf_lxip_usb test on x86_64/hw/pc.

36b55e065a usb_host: check ep pointer before using it
The Usb session allows for submitting packets even when the interface
in question is not yet enabled. Enabling an interface will configure
the udev members properly and is normally done implicitly during
processing of an 'ALT_SETTING' packet.

In case the interface was not enabled this leads to a page-fault in
the USB host-controller driver as 'ep' is NULL.

f6d195a9de nic drivers: provide optional Uplink-client mode
In order to perform a smooth transition from NIC drivers that act only as NIC
session clients to NIC drivers that act only as Uplink session clients, this
commit introduces an intermediate state in which all NIC drivers support both
modes. That said, a NIC drivers mode is now statically determined through a new
optional 'mode' attribute in the drivers <config> tag that can be set to either
'nic_server' (default value) or 'uplink_client'. Reconfiguring this attribute
at a driver doesn't have any effects. Whithout this attribute being set, all
NIC drivers will behave the same as they did before the commit. When set to
'uplink_client', however, instead of providing a Nic service, they request
an Uplink session whenever their network interface becomes "UP" and close the
session whenever their network interface becomes "DOWN".

b097e598f1 usb_hid: use heap instead of dma/mem allocator
The usb_hid driver does not need to distinguish between
normal memory and DMA capable memory, since all requests are routed via the
USB raw session to the usb host driver. The default Malloc implementation
implements this distinction, however exposes restrictions on the size of
allocations. As seen now by several USB HID devices, the size of device
driver allocations depend on read out hardware features and can be
larger than we support with our specialized default Malloc implementation.

Since we don't need this functionality, switching to an well
tested allocator (Heap) which can cope with varying sizes of allocation,
we can mitigate the size restriction.

2eb8c5e21a net: move ascii_to() into Net namespace
The combination of Net::Mac_address and
Genode::ascii_to(Net::Mac_address) required shaky quirks in several
places because GCC is not able to resolve the ascii_to overload if
base/xml_node.h was included to early. The current solution moves the
several ascii_to overloads "closer" to the Net types by putting them
into the Net namespace, where GCC reliably picks them up.

Hence, co-locating the ascii_to() utility with the overload type in the
same scope/namespace is good practice.

This patch removes the now obsolete <nic/xml_node.h> header file.

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.

4007cee852 Fix MAC address printing in dde_linux USB net drivers.
Passing array of unsigned chars to Genode::log() function
makes it converted to void pointer, resulting in printing its address.

Wrapping this array into Genode::Cstring solves this problem
and makes it being printed properly as zero-terminaled string.

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.

d223539165 wifi_drv: ignore socket flags on socket creation
The libc features support for SOCK_CLOEXEC now which gets set via
the type argument in 'libnl'. Since we are only interested in the
actual type, i.e. if it is SOCK_RAW, just ignore the flags.

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).

2208220c12 block session: remove Block::Session::Operations
This patch modernizes the 'Block::Session::info' interface. Instead of
using out parameters, the 'init' RPC function returns a compound 'Info'
object now. The rather complicated 'Operations' struct is replaced by
a 'writeable' attribute in the 'Info' object.

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.

800b4e44b1 Reduce Vfs::Vfs_handle::Context to empty struct type
The "Vfs::Vfs_handle" type should not contain any public members that
can be initialized by the VFS internally and by the application, so
remove inheritance from the "Genode::list::Element" class. The VFS
plugins must instead use lists of "Vfs::Vfs_handle" sub-classes, the
lifetime of which are always managed by the plugin.
