issue #3671
Formerly, _next was always updated to the last free'd allocation, which
left large gaps on alloc/free bursts. Now, we try keep allocation
density high from the start of the array and ensure that allocations
happen at the lowest available index in the bit array.
Fixes#3679
The function is exposed in libc headers provided by Genode, the code for
the function is being compiled and actually works, but the symbol is
missing from the symbols file resulting in linking failures. Add it to
the libc symbols file.

This patch increases the Sculpt version to avoid the risk of binary
compatibility clashes with index files published for the just-released
Sculpt 20.02 version.
Without this patch, the text area would mistakenly delete the characters
types after placing the cursor with the mouse as soon as shift is used
as modifier.
- Don't reset sculpt partition on USB changes whenever ram fs is
selected for use.
- Reconfigure runtime immediately when plugging USB devices.
This prevents the usb-block driver and part_block from
dangling in the graph. They disappear immediately now.
This patch restores the anchoring of the popup menu to the original
behavior, placing the popup to the right of the '+' button. The
anchoring got lost due to the recent structural changes of the GUI,
which affect the hover XML structure.
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.
This patch makes the 'with_raw_node' method more useful in situations
where content of an Xml_node is fed into an Xml_generator, i.e., the
rules report/rom mechanism of the window layouter.
The applicant_to_wake_up() member must be initialized to 0 to keep the
same semantic as before the change by
"base: add mutex as derivate of lock"
Issue #3662
Be less rigid when checking for available network to support
setups where the uplink or depot repositories are provided by
another source than "wired" or "wifi" NIC services,
e.g., a virtual machine with pass-through network device.
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)
Ref #3620
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.

The new text_area component is able to view and edit files.
Internally, it employs a menu_view for the graphics output.
Only basic notepad-like text-editing functions are supported.
At the current time, it is solely meant as a companion of the Sculpt
manager.
Issue #3650
This patch improves the robustness of menu_view when encounting missing
textures, which can happen during development when using styled buttons
and frames. With the patch, menu_view outputs diagnostic messages,
pinpointing the problem.
The patch also updates the texture handling to use the 'File_content'
utility and the VFS for obtaining PNG images.
Issue #3629
This patch allows for the customization of the text color and alpha
value of the label widget by the means of a style-definition file.
The mechanism is exemplified with the new "invisible" label style
that sets the alpha value to zero.

- use Job API as block connection back end
- use Request_stream API as front end
- use Mmio framework for gpt and mbr parsing
- implement sync correctly

Generated a separate 'config.h' for arm, arm_64, x86_32, x86_64 for the
current version (6.1.2) of GMP. This became necessary because
configurations differ for each architecture.

This commit adds dynamic switching in between different defined
screens via keyboard shortcuts, or by editing the rules file.
In the window_layouter package it defines per default ten screens,
reachable by pressing the screen key along with numbers 0-9.
Fix#3646
The mutex class is more restrictive in usage compared to
Genode::Lock.
- At initialiation time it is ever unlocked.
- No thread is permitted to lock twice. Warn about it
in case it happens.
- Only the lock onwer is permitted to unlock the mutex.
Warn about it and don't unlock the mutex in case it happens.
Issue #3612
In preparation of ipc receive, by now a bunch of capabilities got
allocated to be ready iin case of capability receiption. After that
unuse slots were freed again. This overhead of senseless (de-)allocations
is replaced in this commit by just restock capability slots that got
used by the last receive.
Fix#3640
Error return codes are used with non-const functions in the signaling modules.
This would have been impractical for the in-place translation of the module to
Ada in the context of the Spunky project. Besides, it is easy to get rid of
them and it makes the execution flow more clear.
Ref #3308
Besides reducing the use of pointers in base-hw, this prepares for the in-place
translation of the signaling module to Ada in the context of the Spunky
project.
Ref #3308
This prevents the use of Kernel::Object as base class for the specific kernel
objects and instead makes it a member of the kernel objects. Besides
simplifying inheritance hierarchies in base-hw, this prepares for the in-place
translation of the signaling module (and others) to Ada in the context of the
Spunky project.

This prevents the use of C++ features in the public method interface of the
synchronous-IPC module that would be impractical for the in-place
translation of the module into Ada in the context of the Spunky project.
* Get rid of thread accessor.
* Get rid of non-const functions with return values.

Ref #3308
This is a simplication of the asyncronous-IPC module of the base-hw kernel.
Besides structuring the code in a cleaner way, it prepares for the in-place
translation of the module into Ada in the context of the Spunky project.
* Get rid of virtual methods in Ipc_node.
* Move all stuff related to protection domains, capabilities, and UTCBs to
the Thread class. this code might later be moved to a dedicated module, but
for now it's just fine to have it done by the thread module.

Moved code waking up processors for Cortex A53 before changing privilege
level because sending events to higher privilege levels is not allowed.
Fixed enable_mmu for Cortex A53 to properly return cpu id.
Fixed starting code for secondary cores to properly initialize stacks.
Added code to wake up secondary cores on rpi3.
Ref #3573
We cannot count on the correct initialization of the diagnostic register
of the secondary cores. But the boot core gets initialized by the bootchain,
so we can copy over those values.
Fix#3639
If the root child requests a LOG service with the label "unlabeled" then
return a LOG session that logs unprefixed messages. This allows a external
test controller to recognize log messages produced by a blessed component.
This new attribute can be used to enforce a minimum width in the unit of
the size of the character 'x'. Furthermore, the patch sets the minimum
height of a label to 0 if no 'text' attribute is present. By combining
both features, the label becomes usable as a horizontal spacer.
Issue #3629
This patch refines the hover handling such that a float widget never
responds to hovering unless a child is hovered. This way, it becomes
possible to stack multiple float widgets within one frame and still
reach all child widgets.
Issue #3629
Similarly to the way of how a <cursor> can be defined for a <label>
widget, a selection can be expressed as follows:
<label ...>
<selection at="2" length="12"/>
</label>

Issue #3629
When setting the <dialog> attribute 'hover_details' to "yes", the hover
report features the character position of a hovered label.

This patch equips the label widget with the ability to display a text
cursor, as illustrated by the following example:
<label text="...">
<cursor at="10"/>

Issue #3629
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.
Fixes#3627
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.
Fixes#3632
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.
Fixes#3630
By writing out all dangling characters at destruction time, the
'Buffered_output' utility can be used as a local variable rather
than a long-living object.
