e52802162c libc: reimplement synchronization primitives
The new implementation relieves the main entrypoint from monitor jobs
for contended lock primitives and is based on custom applicant data
structures, per-lock resp. per-semaphore applicant lists, and a
libc-internal blockade with timeouts based on libc kernel primitives.

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)

60f5d0e34a gems/animated_geometry.h: increase value range
The value range supported by the 'Animated_rect' utility is constrained
to 2^11 by the used 32-bit integer type. The interpolation is performed
on fixpoint numbers with a fractional precision of 10 bits. The
non-linear interpolation as performed by the 'Lazy_value' utility
involves squaring the values. Hence, the interpolated integral values
must not exceed 2^11 (2*11 bits for the square plus 10 bit for the
fractional part require 32 bits). This range is too small for
high-resolution displays. Hence this patch replaces the 32-bit integer
type by a 64-bit integer type.

3a2895af19 wm: reset pointer position on leave event
The wm used to remember the last pointer position when observing a leave
event. With such a stale pointer position, the wm would eventually
wrongly create an artifical motion event when a supposedly hovered
window changes its position (during an animated move). This can lead to
the propagation of the stale pointer position to the wm client, which,
in turn, may interpret the outdated position (e.g., the menu view would
report a wrong hover state).

This patch removes the stale state by resetting the '_pointer_pos' when
observing a leave event.

and addresses shortcomings with the OpenBSD emulation environment:

* Fix 'delay(9)' implementation - it now properly uses 'us' as unit,
  which results on faster initialization of the drivers.

* Fix LOG output that got lost during commit f23579532 and bring over
  the printf implementation from dde_linux for more structured
  printing.

* As said the driver now recognizes the AUICH devices. So far it was
  only tested with the device model in VirtualBox where it produces
  stuttering audio, investigating the cause is still ongoing.

Fixes #3641.

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')

ff5175ec76 libc: synchronization primitives based on monitor
The libc monitor facility enables the execution of monitor jobs by the
main thread when the monitor pool was charged. In comparison to the
current suspend/resume_all mechanism the main thread iterates over all
job functions in contrast to waking up all threads to check their
conditions by themselves. Threads are only woken up if the completion
condition was met.

This commit is the result of a collaboration with Christian Prochaska.
Many thanks for your support, Christian.

96cde52838 vfs: make <rom> fs robust against invalid ROMs
An invalid ROM dataspace can occur, for example, when requesting a ROM
from the report_rom service before the first report was posted. Such a
<rom> node can still be useful if it's dynamic. E.g., it can be watched.
Hence, the corner case of an invalid ROM dataspace should be gracefully
handled instead of causing an abort.

f82e7df0ba os/buffered_xml.h: support for generating XML
This patch extends the 'Buffered_xml' utility with a new constructor

presents an easy way to generate XML to be consumed locally.

The patch also add a deprecation mark to the original 'xml' accessor
because copying 'Xml_node' objects (here as return value) is dangerous.
The new 'with_xml_node' method should instead be used to access the XML
content stored in the buffer.

cd92b32622 libc: close all open FDs on exit
This is important to issue sync requests for written-to files.

As the closing must be performed by an atexit handler, it happens at a
time _after_ libc plugins are destructed. Consequently an FD allocated
by such a plugin results in a close error, which in turn, does not
destruct the FD. We ultimatedly end up in an infinte loop of
re-attempting the close. For this reason, the patch changes 'close' to
be robust against this special case.

This is generally not a problem because libc plugins are phased out.
However, at present, the libc_noux plugin is still important. With the
changed 'close' in place, there occurred an error message "Error: close:
close not implemented" at the exit of each noux program. This patch
removes the error printing from the libc plugin mechansim to avoid this
noise. The error messages are not important anyway because the
deprecation of the libc plugin interface.

3897ddea03 cxx: don't rely on global ctors
This patch removes the global variable 'blocker', which was expected to
be constructed via the global ctors. This mechanism, however, is not
used for the base library, which resulted in the use of an unconstructed
object. Specifically, the spinlock of the 'Lock' of the 'Registry'
defaulted to the LOCKED state (value 0), which eventually would lead to
a deadlock in the contention case of the cxa guard.

I could observe this deadlock once on during the component startup on
base-linux during the construction of the 'startup_lock'.

This patch fixes the problem by explicitly initializing the registry
of blockers via an init function.

b7fbe65ff2 libc: fork/execve improvements
- Close FDs marked with the close-on-execve flag
  (needed for 'make', which sets the flag for the pipe-in
  FD of forked children)
- Update binary name on execve to use as ROM for subsequent fork
- Enable vfork as an alias for fork (needed by make)
- Purge line buffers for output streams during execve because they
  may be allocated at the allocation heap, which does not survive
  the execve call.
- Consider short-lived processes that may exit while the parent still
  blocks in the fork call.

With these changes, the website generator of genodians.org works without
the need for the Noux runtime.

6b6915e304 ttf_font: fix artifacts with large font sizes
This patch is a follow-up fix for "ttf_font: prevent out-of-bounds
access", which produced sporadic single-pixel artifacts with large font
sizes, e.g., with the monospaced font set to 24px in Sculpt.

The artifacts occurred only for some horizontal sub-pixel positions, in
combination with the font cache, and after the rendering of '>'
characters. They were ultimately caused by the missed clearning of the
first pixel of a glyph where x0 is 1 (e.g., the character 'd'). In this
case, a pixel from the previously evicted cache entry (the '>') shined
through. The patch fixes the problem by clearing the glyph starting from
the first, not the x0's, pixel.

creating a zero-sized archives file for any otherwise correct pkg.

3655ea77a3 depot_autopilot: rework log matching
* The log history of a test is stored as a whole for the lifetime of the test.
* Matching of the log history against log patterns is done correctly now
  (previously, a pattern like "AAB" on an input like "AAAB" wouldn't have
  triggered).
* Use memcmp, memcpy, memmove instead of the former character-wise operations.
* Sanitizing of log input and log patterns now works more generic through the
  new Filter class for all replacements/removals.
* Sanitizing is done as soon as a string is available and remains for the
  lifetime of the test.
* Sanitizing doesn't interfer with the matching algorithm.
* Decomposing into small clearly named functions.

Genode News
===========
Genode OS Framework release 20.02 | 2020-02-28
##############################################
| With version 20.02, Genode makes Sculpt OS fit for running on i.MX 64-bit
| ARM hardware, optimizes the performance throughout the entire software stack,
| and takes the next evolutionary step of the user-facing side of Sculpt OS.
Without any doubt, Sculpt OS has been the driving motivation behind most
working topics featured by the new release. One particularly exciting line
of work is the enabling of Sculpt on i.MX-based 64-bit ARM hardware, which
touched the framework on all levels, from the boot loader, over the kernel,
device drivers, libraries, system management, up to the application level.
The work goes as far as supporting Sculpt OS as a hypervisor platform for
hosting Linux in a virtual machine.
As a second Sculpt-related development, we strive to make the user-visible
side of the operating system better approachable and more logical. With this
background, the current release comes with a profound redesign of the
administrative user interface of Sculpt OS. An updated downloadable system
image will follow soon.
Also related to Sculpt are an updated audio driver based on OpenBSD 6.6,
the support of virtual desktops, and performance optimization of the
Seoul virtual machine monitor on x86 hardware.
Regarding the framework API, the release introduces a new library for
building multi-component applications. It aims to bring the benefits of
Genode's unique security architecture from the operating-system level to the
application level.
These topics are only the tip of the iceberg. For the complete picture,
please consult the
[https:/documentation/release-notes/20.02 - release documentation of version 20.02...]
Road Map for 2020 | 2020-01-20
##############################
| In 2019, we will be concerned about dwarfing the barrier of entry into
| the Genode world.
Following the last year's leitmotif of "bridging worlds", we turn our
attention to the removal of the hurdles faced by aspiring developers and
users. During the annual road-map
[https://lists.genode.org/pipermail/users/2019-December/006987.html - discussion]
on our mailing list, we identified four tangible approaches towards that
goal. First, making Sculpt OS more user friendly. Second, reinforcing trust in
Genode by fostering the framework's high quality. Third, making the tooling
around Genode a joy to use. And finally, the illustration of Genode's
versatility in the form practical use cases.
Besides this overall theme, we plan to continue our commitment to the
NXP i.MX SoC family, revisit Genode's low-latency audio support, and
extend the cultivation of Ada/SPARK within (and on top of) Genode.
More background information about the new road map and a rough schedule are
presented at our official [https:/about/road-map - road-map page].

===============================================
Release notes for the Genode OS Framework 20.02
===============================================
Genode Labs
This year's [https://genode.org/about/road-map - road map] is all about making
Genode and Sculpt OS more approachable. It turns out that the first release of
the year already pays tribute to that goal. First, it equips Sculpt OS with a
much more logical and welcoming graphical user interface
(Section [Redesign of the administrative user interface of Sculpt OS]).
Second, it greatly reduces the friction when hosting existing applications on
Genode by smoothening several rough edges with respect to POSIX compatibility,
and by generally improving performance.
Most topics of the release are closely related to Sculpt. The biggest
break-though is certainly the ability of running Sculpt OS on 64-bit ARM
hardware (Section [Sculpt OS on 64-bit ARM i.MX8 hardware]) along with our
custom virtual machine monitor (VMM). On PC hardware, Sculpt users can enjoy
an updated audio driver and optimizations of the Seoul VMM. Furthermore,
Sculpt's window manager received the much anticipated ability to use virtual
desktops.
At the framework-API level, the most significant changes are the introduction
of dedicated types for inter-thread synchronization patterns
(Section [Base-framework refinements]) and a new library for
bringing the benefits of the Genode architecture to the application level
(Section [New sandbox library based on the init component]).
Redesign of the administrative user interface of Sculpt OS
##########################################################
On our [https://genode.org/about/road-map - road map] for 2020, we stated
the dwarfing of the barrier of entry as our main concern of the year.
We highlighted the ease of use of Sculpt OS as one particular work area.
Removing Unix from the picture
------------------------------
Until now, Sculpt's administrative user interface - lyrically called
Leitzentrale - employed a small Unix runtime and the Vim editor as utility for
basic file operations and for the tweaking of configurations. Even though this
was a practical intermediate solution, we have to face the fact that not
everyone loves the Unix command-line interface as much as we do. Quite the
opposite, actually. When presenting Sculpt, we can clearly sense that people
with a non-Unix background are put off by it. The audience generally loves the
runtime graph, visual cues, and discoverability. Furthermore, command-line
interfaces are (albeit wrongly) perceived as archaic and impenetrable relics
by many computer users who are otherwise perfectly happy with the notion of
files and directories. We identified that file-manipulation tasks performed in
the Leitzentrale are rare and simple. Relying on Unix for those basic tasks is
like taking a sledgehammer to crack a nut. On average, the Leitzentrale is
used in just a few moments a day for basic things like browsing a file-system
hierarchy, glimpsing at the reports stored on the report file system, deleting
or copying a file or two, or tweaking a configuration file. With a Unix shell
presenting one barrier, Vim is certainly an even higher one. Familiarity with
Vim should definitely not be a prerequisite for using an operating system.
Following this reasoning, we decided to swap out the command-line interface
and Vim by a simple GUI-based file browser and a notepad-like editor, which do
not require any learning curve.
Note that even once the Unix command-line interface is removed from Sculpt's
Leitzentrale, advanced users will still be able to manipulate Sculpt's config
file system via a Unix runtime deployed as a regular component, similar to the
use of the noux-system package we have today.
New user-interface layout
-------------------------
The move away from the command-line interface goes hand in hand with the
redesign of the overall user-interface layout. A new panel at the top of the
screen contains two centered tabs for switching between the runtime graph and
the file-system browser.
[image sculpt_20.02_panel]
The storage-management functionality has been moved from the former storage
dialog into the respective nodes of the runtime graph. E.g., to format a block
device, the user can now select a USB or storage node of the graph to get a
menu of block-device-level operations.
[image sculpt_20.02_storage]
The network-management is now located at a drop-down menu that can be toggled
via a button at the right side of the panel.
[image sculpt_20.02_network]
A new button on the left side of the panel allows the user to toggle a
drop-down menu for GUI settings. At the current time, there is only the option
to adjust the font size. In the future, the dialog will give easy access to
the screen-resolution options and the keyboard layout.
The log-message view is now hidden in another drop-down menu that can be
toggled via a panel button. So when starting the system, the user is greeted
with only the runtime graph, which is a much nicer and cleaner looking
experience.
Informative or diagnostic messages are displayed in the left-bottom corner of
the screen.
[image sculpt_20.02_message]
The "Files" tab of the panel switches the main screen area to a simple file
browser that lists all file systems available. By toggling one of the
file-system buttons, the directory hierarchy can be browsed. When hovering
a file, an "Edit" or "View" button appears, which can be used to open
the file in a text area that appears on the right side of the file browser.
The editor supports the usual notepad-like motions, operations, and
shortcuts (control-c for copy, control-v for paste, control-s for save).
[image sculpt_20.02_editor]
Half-way there
--------------
With the current release, one can already accomplish a lot without having to
resort to a command-line interface: connecting to the network, managing
storage devices, installing and deploying software, inspecting the system
state, and tweaking configurations.
There are still a few gaps though. In particular the file browser does
not yet support file operations like the copying, renaming, or removal of
files. For these tasks, the current version of Sculpt still features the
Unix-based inspect window, which can be accessed by toggling the "Inspect"
button inside the USB or storage dialog. Once selected, the panel presents an
"Inspect" tab that features the familiar Unix shell and Vim. Note, however,
that we keep the inspect window only as an interim solution. It will
eventually be removed. As with every new feature, there are still rough edges
to be expected in the editor and file browser, e.g., the editing of files with
long lines or the browsing of directories with many entries is not
appropriately covered yet.
