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.
Issue #3629
- 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
fixes#3652
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.
'config.h' generaton on x86_64 host in'gmp-6.1.2' directory:
for x86_64 (native):
! configure
for x86_32:
! configure --host=x86-pc-linux-gnu --build=x86_64-pc-linux-gnu
for arm:
! configure --host=arm-linux-gnu --build=x86_64-pc-linux-gnu \
! CC=/usr/local/gcc-linaro-arm/bin/arm-linux-gnueabi-gcc ABI=32
for arm_v8:
! configure --host=aarch64-linux-gnu --build=x86_64-pc-linux-gnu \
! CC=/usr/local/gcc-linaro/bin/aarch64-linux-gnu-gcc ABI=64
issue #3598
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.

Besides simplifying the execution flow in the signaling module, 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 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.
* Get rid of pointer return-values.
Ref #3308
Besides simplifying inheritance hierarchies in base-hw, this prepares for the
in-place translation of the synchronous-IPC module to Ada in the context of the
Spunky project.
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.
Ref #3308
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>
