9d417ee2f5 os: Allow VirtIO drivers to be built for RISC-V
Just add riscv spec files. The riscv versions should use MMIO transport
as ARM versions do. They also should work fine for riscv_qemu machine
from genode-riscv repository.

c2d9fbca9b acpi_drv: report Intel opregion copy
acpica and the Intel display driver tries to use the Intel Opregion
simultaneously on Genode, which is not supported nor wanted for IO_MEM region as
which it is handled.

Attempts to remove the access to the region was not successful, since some
SSDT table contains ACPI AML code which is executed regularly and read/write
the Opregion.

The patch adds support to make a copy of the Intel Opregion and report it as
is. The copy was sufficient to make the Intel display driver working to find
and lookup the Intel VBT (video bios table) information to setup all
connectors on a Fujitsu U7411 docking station.

b1195508ba platform_drv: avoid filtering of dev in ALL policy
ACPICA needs access to the host bridge 0:0.0 on Intel, which is also
accessed by the Intel display driver. Since for the Intel display driver the
PCI device is specified in the policy explicitly, the PCI device is filtered
out for the ACPICA driver which uses the policy "ALL".

c38b71146b trace_buffer: only iterate after initialization
There is a race between the trace subject doing the buffer
initialization and the monitor trying to iterate the buffer entries. If
the monitor tries to iterate entries of an uninitialized buffer, it will
read the very first entry twice. The monitor should therefore only start
iteration when the buffer has been initialised.

bd501404db net: add methods required for WireGuard port
* Adds methods for copying raw data to the data field of Ethernet frames and
  UDP packets. This is used in the port to wrap the higher-layer packet data
  prepared by the contrib code with the additionally required headers before
  sending it at a network session.
* Adds a method to cast raw data to an IPv4 packet. This is required in the
  port in order to check values in stand-alone IP packets produced by the
  contrib code before sending them at a network session.
* Adds methods for setting UDP ports given big endian port values without
  having to convert to little endian in the app and then back to big endian in
  the net lib.

de7fdd3e1a platform_drv: wait for device's availability
Instead of returning an invalid device capability when a device
is (not yet) available, e.g. a PCI device is requested before the
PCI bus got parsed accordingly, we check the device capability
within the Platform::Connection utilities, and register temporarily
an Io_signal_handler to wait for changes of the devices ROM, and
try the device aquisition again. Thereby, simple drivers so not have
to take the burden to do so.

To enable this feature for all drivers, we always have to export a
devices ROM, but limit the information about physical resources
(I/O memory addresses, IRQ numbers, I/O port ranges) to clients with
'info=yes' in their policy description.

f032bdf81c legacy_platform_drv: configurable PCI BAR remapping
If PCI devices happen to miss complete configuration after boot, the
platform driver supports <pci-fixup> nodes for concrete devices
(specified by bus-device-functions tuples). The
<bar> node instructs the platform driver to remap BAR id 0 to address
0x4017002000, which amends the BIOS configuration and is stringently
required for BARs with address 0.

! <pci-fixup bus="0" device="0x15" function="3">
!   <bar id="0" address="0x4017002000"/>
! </pci-fixup>

a45aabe68c usb_block: handle block requests in Signal_handler only
Before this commit, the block-request handler was implemented as
Io_signal_handler and, additionally, the USB driver called the
block-request handler on request completion directly on I/O level. This
is generally a bad idea because I/O handlers should avoid to have direct
global side effects. In contrast, application logic should be
implemented in way that it consumes atomic state changes after I/O
completed. Now USB I/O completion locally submits a signal to the
block-request Signal_handler.

b9141f98af test/black_hole: fix "packet alloc failed"
The Uplink_test used to end in an uncaucht exception about a failed packet
allocation on several x86_32 platforms.

* Destruct and re-construct the corresponding TX packet allocator during a
  link-down-up step in the Uplink test. Fixes the exceptions but results in a
  never ending test.
* Decouple the link-down-up steps from the handling of packet stream signals
  by simply triggering it with a local periodic timeout of 1 sec period.
  This prevents that the Uplink_test never finishes because it destructs the
  Uplink connection too often.
* The test finishes not before at least 3 link-down-up steps were executed.
* Replace the Allocator_avl's used for the TX packet allocators of the Nic
  and Uplink Connection with the better suited Nic::Packet_allocator.

ef8c98cb71 nic_router: merge packet stream signal handlers
The NIC router used to handle each type of packet-stream signal with a distinct
method in the Interface class. However, merging those methods has advantages.

It ensures that sent packets that were already acknowledged by the counter side
are always released before handling received packets. This frees packet stream
memory which facilitates the potential allocation of response packets while
handling received packets. Furthermore, it simplifies the code and reduces the
number of entry points into the router.

This commit also removes the installation of signal handlers at packet streams
for events that are of no interest for the router (TX-ready-to-ack /
RX-ready-to-submit at NIC sessions and RX-ready-to-ack / TX-ready-to-submit at
Uplink sessions).

bb26a986e6 sculpt: add trace_logger as optional launcher
This patch adds the trace-logger utility to the default set of packages
along with an optional launcher. With this change, only two steps are
needed to use Genode's tracing mechanism with Sculpt:

- Add 'trace_logger' to the 'launcher:' list of the .sculpt file

- Either manually select the 'trace_logger' from the '+' menu,
  or add the following entry to the deploy configuration:

    <start name="trace_logger"/>

By default, the trace logger is configured to trace all threads
executed in the runtime subsystem and to print a report every 10
seconds. This default policy can be refined in the launcher's <config>
node. Note that the trace logger does not respond to configuration
changes during runtime. Changes come into effect not before restarting
the component.

Subjects that belong to the same PD are grouped together. The formerly
optional affinity and activity options have been removed. Those
information are now unconditionally displayed. The trace entries
belonging to a thread appear as slightly indented.

The patch also updates the coding style, avoiding excessively long
lines.

be0a1742ac base: distinct TRACED from ATTACHED trace subjects
This patch makes the trace-subject state as reflected to the trace
monitor more accurate.

Until now, a subject could be in UNTRACED or TRACED state. In reality,
however, there exists an intermediate state after the trace monitor
called 'trace' for the subject but before the subject locally activated
the tracing (done when passing a trace point). This intermediate state
was reflected as UNTRACED. Consequently, threads that never pass a trace
point (e.g., just waiting for I/O) would remain to appear as UNTRACED
even after enabling its tracing by the trace monitor. This is confusing.

This patch replaces the former UNTRACED and TRACED states by three
distinct states:

  UNATTACHED  prior any call of 'trace'
  ATTACHED    after a trace monitor called 'trace'
              but before the tracing is active
  TRACE       tracing is active

a9022d8451 sandbox: improve CPU-quota accounting
The existing assignment of CPU quotas did not anticipate the dynamic
reconfiguration of init. It merely tracked the available CPU quota by
deducing the consumed amount from a global variable but never
replenished the value. This worked for static scenarios but failed in
situations where components are dynamically re-started.

So far this deficiency remained detected because CPU quotas were not
used in highly dynamic systems like Sculpt OS. However, this has
recently changed by commit "sculpt: assign CPU quotas".

The patch improves the accounting by mirroring the existing handling of
RAM and cap quotas. Note that the CPU-quota accounting is still rather
limited. In particular the dynamic rebalancing is not yet supported.

ca9460aead event_filter: touch/press untouch/release sequence
This commit changes the touch-click filter to adhere the following
sequence:

  touch         (physical)
  press         (artifically generated)
  release       (artificially generated)
  release_touch (physical)

This order is important because nitpicker's focus handling takes
press/release events into account. If the release-touch event appears
before the release event, nitpicker subsumes the release-touch event
to the sequence that started with the press event, instead of handling
it as a free-standing event.

c2efa5406e xml_node: support backslash as attribute value
XML allows attribute values like <node attr="\"/>. The XML parser
wrongly reflects this case as 'Invalid_syntax'. This behavior stems from
the implicit use of the 'end_of_quote' function, which considers the
sequence of '\"' as a quoted '"' rather than the end of a quoted string.

The patch solves this problem by making the 'end_of_quote' part of
the tokenizer's scanner policy.

The patch removes the 'end_of_quote' function from 'util/string.h'
because it is not universal, and to avoid the ambiguity with
'SCANNER_POLICY::end_of_quote'.

number of the click, which allows for freshness checks by the consumer of

e4f62380d7 base: Pd_session::dma_addr, Pd_session::attach_dma
This patch enhances the PD-session interface with the support needed for
user-level device drivers performing DMA. Both RPC functions are
intended for the direct use by the platform driver only. If invoked for
PDs that lack the managing-system role, the operations have no effect.

The 'dma_addr()' RPC function allows the platform driver to request the
DMA address of a given RAM dataspace. It is meant to replace the
'Dataspace::phys_addr' RPC function.

The 'attach_dma' RPC function adds the given dataspace to the device
PD's I/O page table. It replaces the former heuristics of marking DMA
buffers as uncached RAM on x86.

With this patch, the UNCACHED attribute of RAM dataspaces is no longer
used to distinguish DMA buffers from regular RAM dataspaces.

4dfa7902db os: Input::Event:Seq_number event type
The new event type allows for the propagation of sequence numbers as a means to
validate the freshness of input handling. E.g., an menu-view-based application
can augment artificial sequence numbers to the stream of motion events supplied
to 'menu_view'. Menu view, in turn, can now report the latest received sequence
number in its hover reports, thereby enabling the application to robustly
correlate hover results with click positions.

df2e7fa842 vfs_block_file_system: remove Signal_receiver
The VFS block plugin used to depend on the blocking semantics of the
packet stream's 'get_acked_packet'. This patch replaces this dependency
by the use of 'wait_and_dispatch_one_io_signal'. However, in order to
implement this change, the custom instance of a 'Signal_receiver' had to
be removed as well.

To keep this patch as little invasive as possible, it does not touch the
direct use of the block session's packet stream, which should better be
replaced by the 'Block::Connection::Job' API.

7aa9cf9b37 uplink_client_base: add handlers for zynq_nic_drv
The zynq_nic_drv follows a zero-copy approach and thus uses the packet
buffers as DMA memory. In order to know when the RX DMA memory can be used
for another packet, a custom ack_avail_handler is needed.
Similarly, packets received from the Uplink session are not copied to a
DMA buffer but to directly passed on as DMA memory. For this purpose,
a a custom packet_avail handler is needed.

The only remaining legitimate use case of the direct interaction with

83626b18f0 uplink_client_base: remove unused code
So far, the generic Uplink connection code considered NIC drivers to transmit
connection RX packets in three different manners. Most of the drivers follow
the "normal" way of transmission with only one driver callback from generic
code. The monolithic USB NIC-driver, however, used to send in a "burst" mode
that required a dedicated path with multiple driver callbacks in the generic
code. And then there were drivers that had a fully custom function for doing
transmissions.

Also for handling connection TX acks, there was a "normal" and a
"custom handler" way.

Today, all NIC drivers in the Genode repos and the Genode-World repo follow the
"normal" way. Therefor, the unused code can be removed.

b723b11b30 Modularize Sculpt OS image creation
This patch equips Sculpt with the ability to customize the system image
in very flexible ways.

All customizable aspects of the image have been relocated from the
former sculpt.run script and the accompanied gems/run/sculpt/ directory
to a new location - the sculpt/ directory - which can exist in any
repository. The directory at repos/gems/sculpt/ serves as reference.

The sculpt directory can host any number of <name>-<board>.sculpt files,
each containing a list of ingredients to be incorporated into the
Sculpt system image. The <name> can be specified to the sculpt.run
script. E.g., the following command refers to the 'default-pc.sculpt'
file:

  make run/sculpt KERNEL=nova BOARD=pc SCULPT=default

If no 'SCULPT' argument is supplied, the value 'default' is used.

A .sculpt file refers to a selection of files found at various
subdirectries named after their respective purpose. In particular, There
exists a subdirectory for each file in Sculpt's config fs, like
nitpicker, drivers... The .sculpt file selects the alternative to use
by a simple tag-value notation.

  drivers: pc

The supported tags are as follows.

*Optional* selection of /config files. If not specified, those files are
omitted, which prompts Sculpt to manage those configurations
automatically or via the Leitzentrale GUI:

  fonts
  nic_router
  event_filter
  wifi
  runtime
  gpu_drv

Selection of mandatory /config files. If not specified, the respective
'default' alternative will be used.

  nitpicker
  deploy
  fb_drv
  clipboard
  drivers
  numlock_remap
  leitzentrale
  usb
  system
  ram_fs

Furthermore, the .sculpt file supports the optional selection of
supplemental content such as a set of launchers.

  launches: nano3d system_shell

Another type of content are the set of blessed pubkey/download files
used for installing and verifying software on target.

With the new version, it has become possible to supply a depot with the
the system image. The depot content is assembled according to the 'pkg'
attributes found in launcher files and the selected deploy config.
The resulting depot is incorporated into the system image as 'depot.tar'
archive. It can be supplied to the Sculpt system by mounting it into the
ram fs as done by the 'ram_fs/depot' configuration for the ram fs.

It is possible to add additional boot modules to the system image. There
are two options.

  build: <list of targets>

This tag prompts the sculpt.run script to build the specified targets
directly using the Genode build system and add the created artifacts
into the system image as boot modules.

  import: <list of depot src or pkg archives>

This tag instructs Sculpt to supply the specifid depot-archive content
as boot modules to the system image. This change eliminates the need for
board-specific pkg/sculpt-<board> archives. The board-specific
specializations can now be placed directly into the respective .sculpt
files by using 'import:'.

To make the use of Sculpt as testbed during development more convenient,
the log output of the drivers, leitzentrale, and runtime subsystems
can be redirected to core using the optional 'LOG=core' argument, e.g.,

  make run/sculpt KERNEL=linux BOARD=linux LOG=core

The former pkg/sculpt-installation and pkg/sculpt-installation-pc
archives have been replaced by pkg/sculpt_distribution-pc, which
references the generic pkg/sculpt_distribution archive. Those pkgs are
solely used for publishing / distribution purposes.

3cc6df3116 base: tighten affinity handling
This patch improves the robustness of the CPU-affinity handling.

- The types in base/affinity.h received the accessors
  'Location::within(space)' and 'Affinity::valid', which alleviates
  the fiddling with coordinates when sanity checking the values,
  in init or core.

- The 'Affinity::Location::valid' method got removed because its
  meaning was too vague. For sanity checks of affinity configurations,
  the new 'within' method is approriate. In cases where only the x,y
  values are used for selecting a physical CPU (during thread creation),
  the validity check (width*height > 0) was not meaningful anyway.

- The 'Affinity::Location::from_xml' requires a 'Affinity::Space'
  as argument because a location always relates to the bounds of
  a specific space. This function now implements the selection of
  whole rows or columns, which has previously a feature of the
  sandbox library only.

- Whenever the sandbox library (init) encounters an invalid affinity
  configuration, it prints a warning message as a diagnostic aid.

- A new 'Affinity::unrestricted' function constructs an affinity that
  covers the whole affinity space. The named functions clarifies
  the meaning over the previous use of the default constructor.

- Core's CPU service denies session requests with an invalid
  affinity parameter. Previously, it would fall back to an
  unrestricted affinity.

643747b912 os: Refactor VirtIO::Queue implementation.
The key changes in this patch are:
* Buffer allocation is moved into a separate Buffer_pool helper. The
  implementation of the buffer allocation strategy does not change.
  The helper allocates a single RAM dataspace and splits it in multiple,
  equally sized chunks.
* Management of main descriptor ring is enacapsulated in Descriptor_ring
  helper class.
* Use separate RAM dataspaces for descriptor rings and buffers.
  Previously both of them were packed into a single dataspace. This
  might have been more RAM efficient, but IMO it made the code uglier and
  harder to understand.
* All of the VirtIO::Queue members are now initialized on the class member
  initializer list. This is possible due to previously listed changes.
* Since all VirtIO::Queue members are initalized on member initalizer
  list, some additional ones can be marked as const, ex _avail, _used ring
  pointers.
* Move descriptor writing code into a common method used by both
  write_data and write_data_read_reply members. This avoids some code
  duplication between those methods.
* Get rid of request_irq argument that most public VirtIO::Queue methods
  accept. None of the existing drivers use it and I doubt this will
  change any time soon.
* Use Genode namespace by default in Virtio.

This patch also fixes at least one bug that I discovered while working
on VirtIO block device driver. Namely, when chaining descriptors only the
first descriptor in the chain should be exposed in the available ring.

162ddb1fdb virtio: fix len calculation
Thanks to Piotr Tworek for the fix and his explanation as follows:

The basic idea is to try to fit payload data into the descriptor used to
send the header. If there is no payload, or the payload fits exactly
into the remaining space in the header decriptor, len should be 0 and
only one descriptor should be used. In such case the "next" and "flags"
members of the descriptor structure should be set to 0.

In case there is some extra payload data to send, but its size is
bigger than the remaining free space in the descriptor used to send the
header, len should contain the remaining size of the payload that
can't be sent via the header descriptor. The code will then chain
additional descriptors to handle this remainder.

With the len variable shadowing, the code will never queue the remaining
data.

7c1888644a os: Add VirtIO framebuffer driver.
This implements the necessary bits to provide 2D framebuffer support on
top of VirtIO GPU device as implemented in Qemu. I don't know if any
other implementation of this specific device exists.

Compared to the ramfb driver which already exists in Genode Virtio FB driver
has one major benefit. It allows Qemu window to be dynamically resized at
runtime. The driver will treat this as resolution change and act accordingly.
Ramfb driver can currently only use the hardcoded 1024x768 screen size. Changing
screen resolution might not sound like a big deal, but it is rather useful to
run Genode on Qemu in full screen mode.

2ec9e69fd4 os: Add support for reading VirtIO responses.
Some more advanced devices like VirtIO GPU do expect they can receive
responses to VirtIO commands they issue via VirtIO queue. Such responses
are not sent via a separate device writeable queue. Instead the driver
is expected to queue some additional descriptors and buffers which the
device can then use to provide the reply.

This patch adds support for such write-data-read-response opeartion to
Genode VirtIO::Queue implementation. The implementation is pretty simple
and does not support any fancy features like receiving the response
asynchronously. Instead the operation will use caller provided callback
to wait for the device to process the command. Once this callback
returns the write-data-read-response VirtIO::Queue function will invoke
another callback passing received response as argument.

To largely uphold compatibility with components using the original

f2a627c107 os: Pin_control and Pin_state session interfaces
The new interfaces are meant to gradually replace the existing
Gpio_session interface.

- Each session refers to a single pin.
- The session types distiguish the direction of the signal as input or
  output.
- Pin coordinates can be selected via session labels.
- GPIO interrupts are covered by the regular IRQ session interface.

The interfaces are accompanied by framework utilities and interfaces:

- os/pin_driver.h
- pin_control_session/component.h
- pin_state_session/component.h

These headers relieve GPIO drivers from implementing boilerplate code by
providing device-agnostic portions. The A64 pio driver serves as
reference for using those utilities.

ee463b21ae nitpicker: fix interplay of hover with dragging
This patch extends the notion of having only one uniquely hovered client
in the presence of held keys.

If motion occurs once a key is pressed (e.g., while dragging), the
receiver of the key sequence observes the motion events. In this case,
we have to submit an artificial leave event to the originally hovered
client so that no more than one client observes itself as being hovered
at the same time. Once the key sequence is finished, the hovering is
updated again, eventually presenting a motion event to the originally
hovered client and a leave event to the receiver of the key sequence.

6f1d3862cd base: introduce Env::try_session
The new 'Env::try_session' method mirrors the existing 'Env::session'
without implicitly handling exceptions of the types 'Out_of_ram',
'Out_of_caps', 'Insufficient_ram_quota', and 'Insufficient_cap_quota'.
It enables runtime environments like init to reflect those exceptions to
their children instead of paying the costs of implicit session-quota
upgrades out of the own pocket.

By changing the 'Parent_service' to use 'try_session', this patch fixes
a resource-exhaustion problem of init in Sculpt OS that occurred when
the GPU multiplexer created a large batch of IO_MEM sessions, with each
session requiring a second attempt with the session quota upgraded by
4 KiB.

6093f8ad81 gpu/intel: deal with insufficient amount of CAPS
'Out_of_ram' was so far the only exception a client had to deal with
during buffer managment. Allocating memory, however, does not only
consume RAM quota but CAP quota as well.

This commit tries to mitigate that shortcoming by reflecting the
'Out_of_caps' state back to the client. Furthermore it allows for
resource accounting on certain client allocations, e.g. buffers.

GPU multiplexer.

27e55dab3e platform_drv: check quota before allocating buffer
The platform driver uses a 'Constrained_ram_allocator' to allocate
meta-data on behave of a client. It uses the PD session as
'Ram_allocator' back end that in return is implemented via the
'Expanding_pd_session_client'.

Whenever the PD client itselft comes into resource shortage it will
ask its parent unconditionally. However, depending on the integration,
such a request may be left unanswered.

This commit introduces a check to prevent that situation from
occurring. In case the platform driver notices the resource shortage
it will reflect that back to the client.

90e151e2c4 gpu: add 'complete' RPC call
This call allows for checking if the given execution buffer has been
completed and complements the completion signal. Initially the GPU
multiplexer always sent such a signal when the currently scheduled
execution buffer has been completed. During enablement of the 'iris'
driver it became necessary to properly check of sequence number.

In case of the Intel GPU multiplexer the sequence numbers are
continous, which prompted the greater-than-or-equal check in the
DRM back end. By hidding this implementation detail behind the
interface, GPU drivers are free to deal with sequence numbers any
way they like and allows for polling in the client, where the
completion signal is now more of a progress signal.

e37792ce94 gpu: introduce information dataspace
The current info implementation (as RPC) is limited in a few ways:

  * The amount of data that may be transferred is constrained by the
    underlying base platform
  * Most information never changes during run time but is copied
    nonetheless
  * The information differs depending on the used GPU device and
    in its current implementation only contains Intel GPU specific
    details

With this commit the 'info' RPC call is replaced with the
'info_dataspace' call that transfers the capability for the dataspace
containing the information only. This is complemented by a client
local 'attached_info' call that allows for getting typed access to
the information. The layout of the information is moved to its own
and GPU-specific header file, e.g., 'gpu/info_intel.h'
