93288bccb3 os: Refer to ::Sandbox::Child explicitly.
When compiling this code, clang complains reference to 'Sandbox' is
ambiguous. It can either mean ::Sandbox namespace from
os/src/lib/sandbox/types.h, or Genode::Sandbox declared in
repos/os/include/os/sandbox.h. Since the code refers to ::Sandbox::Child
and its already in ::Sandbox namespace we can just drop "Sandbox" and
refer to just Child, which makes clang happy.

8d5005e03a os: add VirtIO nic driver
The driver is faily simple and does not support fancy features like
TCP checksum offloading or vlan filtering, but it is fully capable of
running every Genode network based scenario I've tried. Its currently
known to work on virt_qemu arm platforms and x86_64.

7fbb245710 os: add VirtIO device helper classes.
To simplify writing native VirtIO drivers for Genode add helper classes
representing VirtIO device and queue. The queue implementation should
be platform independant. The device abstraction however is closely tied
to the VirtIO transport being used (PCI/MMIO). Both PCI and MMIO
implementations expose the same public API so the actual driver logic
should be the same regardless of which transport is used.

Its also important to note that the PCI version of Virtio::Device
currently does not support MSI-X interrupts. Unfortunately my kowledge
about PCI bus is very limited and my main area of interest was to get
VirtIO drivers working on virt_qemu ARM/Aarch64 platform. As such all
the VirtIO drivers I plan to submit will work with PCI bus, but might
not use some extended capabilities.

9bd548c4bd os: add platform_drv config generator for virt_qemu
The VirtIO device configuration on Qemu is dynamic. The
order and presence of different command line switches affects
base address and interrupt assignment of each device. One could
probably hard-code the necessary switches and resulting XML ARM
platform driver configuration in each run script, but this seems
like troublesome and hard to maintain solution.

This patch explores an alternative approach to the problem.
It implements a ROM driver which probes the address space region
Qemu virt machines assign to VirtIO MMIO devices and exposes the
result as XML via a ROM session. This XML output can be fed directly
as config to the generic ARM platform driver.

fe0ad0addb tool: Consolidate qemu nic setup.
Right now the same code dealing with nic setup on qemu is duplicated
in many different run scripts. It makes it unnecesarily complex to
change the existing config or add support for new nic types. Lets move
all this common code to qemu.inc.

5d808cdc01 platform_drv: extend MSI-X supports
The patch handles the case, that the memory for the MSI-X table is part
of one of the Pci::Resource Memory BARs, which got allocated beforehand already.

With this commit, the platform driver will not fall back to use legacy IRQs or MSI, whereby MSI-X is available actually. Additionally, this patch avoids a lot of red
messages about non available IO-MEM printed by the roottask.

04821b1abc nitpicker: apply focus change w/o input events
This patch fixes the corner case where the keyboard focus is defined
independently from user interactivity, e.g., the activation of a
screensaver or lock screen.

In this case, nitpicker would update its internal focus state not before
the next input event is handled. Should this input event be a press
event, this event would wrongly be delivered to the prior focused
session. Another problematic situation is the initial state before the
very first input event occurs. Since the focus remains undefined until
the first input event is handled, an initial key press event would not
be delivered.

This is a regression caused be the transition to the event-session
interface and the removal of the nitpicker's periodic way of operation.
The patch fixes the problem by applying pending focus changes not only
at the input processing but also on the code path that responds to focus
changes (e.g., focus-rom update).

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.

7de2b040f8 vfs: deliver ACKs after config change
This is needed to enable VFS plugins to notify VFS clients about file
changes that depend on the plugin configuration, E.g., whenever the vfs_ttf
plugin responds to a font-size change, it generates a watch notification
for the glyphs file. Since the change is independent from I/O, we need
to manually call 'handle_io_progress'.

328a4fa644 nitpicker: update hovering on view-stack changes
With the change of nitpicker to the event session interface, the
formerly periodic hovering updates moved to the - now sporadic - input
processing. This has the unfortunate side effect that hovering changes
caused by non-user-input, in particular view-stack changes issued by the
GUI clients that change the view under the current pointer position,
would no longer be reported immediately but only after receiving the
next incoming input event.

This patch reworks the hover handling such that potential hovering
changes due to view-stack operations are evaluated immediately by
those operations, covering the update of the hover report and the
generation of artificial enter/motion events.

17a6318ad6 vfs: process all acks in each iteration
This patch solves a corner case where one long-active job (e.g.,
read-ready request) stays at the beginning of the '_active_jobs' queue
without an ack. In this case, the '_try_acknowledge_jobs' method would
wrongly stop processing the subsequent acknowledgements. In practice,
this can lead to a delayed sending of acknowledgements until new I/O or
client requests occur. In particular, Vim in Sculpt's inspect window
sometimes did not immediately respond to key presses during tab
completion. Here, the read-ready request of the terminal prevented the
acknowledgement for read of directory entry from being delivered until
the next key was pressed.

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.
