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.

2e22498e5a nitpicker: no framebuffer and input by default
This patch prevents nitpicker from requesting a framebuffer and input
session by default because the regular use of nitpicker relies on the
capture-session and event-session interfaces by now.

For supporting the nested use of nitpicker via the gui_fb component, it
is still possible to enable the traditional behavior by explicitely
setting the 'request_input' and 'request_framebuffer' config attributes
to "yes".

9662d89cfb Replace input filter with event filter
This commit applies the transition from the "Input" session to the "Event"
session to the event-filtering mechansim. The functionality of the
input_filter is now provided by the event_filter. The event filter
requests only one "Event" session as destination for the filter result,
which is usually routed to the nitpicker GUI server. It provides an
"Event" service to which any number of event sources can connect.

The configuration of the filter chain remains almost the same. Only the
declaration of the <input> nodes is no longer needed. Instead, the
configuration must specify <policy> nodes, which define the mapping of
"Event" clients (event sources) to the inputs used in the filter chain.

The patch adjusts all uses of the nitpicker GUI server accordingly such
that the event filter reports events to nitpicker's event service
instead of having nitpicker request an "Input" session. This dissolves
the dependency of nitpicker from input drivers.

c502e1d095 input_filter: prepare for refactorization
This patch brings the input filter into a shape that is easier to
re-mold into an event filter, reversing the client/server roles of
the component.

* The 'Sink &destination' is no longer passed as constructor argument
  to the individual filters but passed as argument to the 'generate'
  method. This way, the final destination does not need to exist at
  the construction time of the filter chain but can be created on
  the fly (clearing the way for using 'Event::Client::with_batch').

* A new 'Source::Filter' interface with the 'apply' method aids the
  cascading of filters during 'generate'. The modules now implement
  the 'Source::Filter::filter_event' interface instead of the
  'Source::Sink::submit_event' interface.

* Since the 'Sink &destination' is no longer a member of the filter
  modules, character-repeat events can no longer be emitted in an
  ad-hoc way. Instead, the character-repeat mechanism now invokes
  a new 'Trigger::trigger_generate' hook that prompts the execution
  of the regular 'generate' mechanism by the main program.

This patch is supposed to leave the semantics of the input filter
unchanged (validated by the input_filter.run script).

7bac1ec7e5 Adapter for connecting input and event servers
This is an intermediate helper component for the transition of input
servers into event clients. It works analogously to the
input_event_bridge but it connects servers instead of clients.
In particular, it can act as glue between a traditional input driver
that provides an input service and the event filter that provides an
event service. Thanks to this component, each driver can be migrated to
the event-client interface individually.

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.

Until now, Genode's framebuffer session interface was based on the

The patch also adjusts the users of the drivers_interactive packages,

sufficient for covering high resolutions at 32 bits per pixel and to

e56dd15a4b vfs: extend <zero> fs to limit amount of zeros
Setting the 'size' attribute will restrict a reader to consume
0s up to the specified amount per VFS handle. The attribute is
parsed as 'Number_of_bytes', which will limit the amount to the
maximum of the addressable memory on the platform.

This addition comes in handy when needing to provide a synthetic
empty file with a fixed size.

103ae9df4a block_tester: limit batching in sequential test
So far the condition whether to spawn a new job or not depended on
the amount of data already processed. This could lead to spawning
more jobs than necessary if batching is used and in return could
result in creating invalid requests in case the tested block session
is not large enough.

In addition to checking the amount of data the test now stores the
number of the last block and checks if the current request is in
range. This properly limits the total amount of requests.

42fddf8390 Cleanup shared-object support mechanics
The former ldso-startup static library (now called ldso_so_support) is
used to spice each shared object/library with local support code for the
dynamic linker (execution of static constructors and ARM-EABI).
Therefore, the library must be statically linked to each dynamic
library.

As a result recipes for dynamic libraries must always depend on the "so"
API, which makes ldso_so_support.mk and so_support.c available
independent of "base". Additionally, ldso_so_support is also provided in
the libc API to cut the dependency early for libc/posix libraries.

9d67f9fc8e Remove Allocator_guard
This patch removes old 'Allocator_guard' utility and replaces its use
with the modern 'Constrained_ram_allocator'.

The adjustment of core in this respect has the side effect of a more
accurate capability accounting in core's CPU, TRACE, and RM services.
In particular, the dataspace capabilities needed for core-internal
allocations via the 'Sliced_heap' are accounted to the client now.
The same goes for nitpicker and nic_dump as other former users of the
allocator guard. Hence, the patch also touches code at the client and
server sides related to these services.

The only remaining user of the 'Allocator_guard' is the Intel GPU
driver. As the adaptation of this component would be too invasive
without testing, this patch leaves this component unchanged by keeping a
copy of the 'allocator_guard.h' locally at the component.

f0c4fc1e22 sandbox: defer requests for upcoming server
The sandbox library supports the forwarding of session requests from the
outside to one of the hosted children according to a policy. This patch
introduces the distinction between two cases, which previously triggered
the denial of the session request.

- There exists no matching policy for the requested session
- There exists a matching policy but the referred server child
  does not exist (yet)

Whereas the proper response to the first case is the denial of the
request, the second case can occur in situation where a dynamic init is
used to implement a staged startup, for example via the deploy
mechanism. In such cases, a policy may exist as a static rule while the
server has not been started yet. This patch changes the behavior such
that such requests are stalled.

The patch is accompanied with test cases for exercising both situations.

150d143755 os: use Request_stream API in NVMe driver
As a result of the API change the memory handling could be simplified.
Since the Block session dataspace is now directly used for DMA, we
actually only have to provide the memory for setting up PRP lists for
large requests (for the moment more than 8 KiB of data).

As we limit the maximum data transfer length to 2 MiB, we get by with
just a page per request. Those memory is allocated beforehand for the
maximum number of I/O requests, which got bumbed to 512 entries. Since
not all NVMe controllers support such large a maximum data transfer
length and this many entries, especially older ones, the values are
capped according to the properties of the controller during
initialization. (The memory demands of the component are around 3 MiB
due to setting up for the common case, even if a particular controller
is only able to make use of less.)

(Although there are controllers whose maximum memory page size is more
than 4K, the driver is hardcoded to solely use 4K pages.)

In addition to those changes, the driver now supports the 'SYNC' and
'TRIM' operations of the Block session by using the NVMe 'FLUSH' and
'WRITE_ZEROS' commands.

following scenario:

  <vfs>
    <dir name="home">
      <ram/>
      <rom name="..."/>
    </dir>
  </vfs>

The following sequence of commands wrongly resulted in "Operation not

ba55409c86 nic_router: keep dyn IP when updating domain obj
When updating the domain object of interfaces that stay with the same domain
during a reconfiguration, until now, the normal "detach raw" function was used.
This caused the old domain object to discard a dynamic IP config as all
interfaces detached. This caused interfaces also to discard network links
established with the old configuration although it wasn't necessary. Thus, now
we use a dedicated "detach" in case that an interface actually stays with its
domain. This new "detach" doesn't decrease the interface counter of the domain,
so, it'll not discard its dynamic IP config. If, however, during a
reconfiguration, there's no interface calling this function (all interfaces
move to another or no domain), the dynamic IP config is still discarded as
expected.

to handle packet headers other than that of DHCP.

6d48b5484d hw: correct the ARM cache maintainance operations
This commit fixes the following issues regarding cache maintainance
under ARM:

* read out I-, and D-cache line size at runtime and use the correct one
* remove 'update_data_region' call from unprivileged syscalls
* rename 'update_instr_region' syscall to 'cache_coherent_region' to
  reflect what it doing, namely make I-, and D-cache coherent
* restrict 'cache_coherent_region' syscall to one page at a time
* lookup the region given in a 'cache_coherent_region' syscall in the
  page-table of the PD to prevent machine exceptions in the kernel
* only clean D-cache lines, do not invalidate them when pages where
  added on Cortex-A8 and ARMv6 (MMU sees phys. memory here)
* remove unused code relicts of cache maintainance

In addition it introduces per architecture memory clearance functions
used by core, when preparing new dataspaces. Thereby, it optimizes:

* on ARMv7 using per-word assignments
* on ARMv8 using cacheline zeroing
* on x86_64 using 'rept stosq' assembler instruction

103dcdeea8 vmm: ARMv8 virtio improvements
net:
* increase queue size to 1024 (more stable on Linux)
* use mac address from Nic session instead of random one
* handle data that is larger than rx descriptor correctly (copy less)
* clear descriptor header (12 bytes) on rx

generic:
* always use 'avail_idx' (tx and rx)
* added barriers when reading/writing queues (TMP)

7780ee6a34 vmm: do not lock inside VMM
We do not use the VMM with several CPUs until now.
On the other hand there is a dead-lock due to the
generic timer calling the cpu handler function explicitly,
which already holds the lock. For the time-being remove the lock.

52e582132f os/vfs.h: handle corner case in join function
When specifying "/" or "" as rel_path to the 'Directory' constructor,
the constructed directory should refer to the same directory. The
implementation of the join utility did not consider this corner case. It
occurred during the attempt to use fs_query with "/" given as path.

This patch also adds a Directory::Entry::dir accessor that returns true
if the entry is a directory.

8a7deae238 ahci: switch to request stream API + structural changes
- Remove dated 'Block::Driver' front end and implement
  'Block::Request_stream' front end
- Remove all dynamic memory allocations but DMA memory allocations
- Remove 'Platform_hba' and implement platform specific functions in
  'spec/<platform>/*'
- Ata and Atapi don't inherit from 'Port' any more, but are a member of
  'Port' as a protocol implementation
- Use platform driver for MMIO mappings (x86)
- Exchange stateful initialization of Ata/Atapi with a sequential
  initialization using 'wait_for_any' and 'retry' patterns
- Fix Atapi initialization by setting the byte count limit
- Set FIS receive base only when Cmd::FRE is disabled and Cmd::FR is 0
- Put everything in namespaces ('Ahci', 'Ata', or 'Atapi')
- Ata decides during read/write operations to use native-command queuing
  or normal DMA requests
- Remove port claiming logic (is now done via 'Constructibles')
