Until now, it was possible to use bad Free-Tree/VBD configurations with the
<initialize/> command. The tresor tester didn't complaining about it but the
tresor lib crashed or, worse, corrupted the tresor container. Now, the tresor
tester checks things, like for instance, that "nr_of_children" must be a power
of 2.
Ref #4971
The Superblock Control module now issues a snapshot garbage collection on each
incoming request. In return for that, the commit removes all calls to the
garbage collection from other modules.
Ref #4971
The Virtual Block Device module used to create a local copy of the Snapshots
array respectively Snapshot root it received with an incoming request. After
finishing the VBD operation on the copy, the source module of the request
used to back-copy the resulting Snapshot array resp. Snapshot root. This is
not only less efficient than referencing but also allowed a bug to sneak into
the new C++ implementation.
In contrast to the old Ada/SPARK implementation (CBE), the new design doesn't
allow for global objects that can be accessed by any module without receiving a
reference in a module request. Therefore, the Free Tree module has to receive a
reference to a Snapshots array with each request in order to be able to use it.
In our case, these requests are allocations for a "Write" operation from the
VBD. However, the VBD itself receives only the one Snapshot required for
writing and therefore causes the Free Tree to make bad decisions on whether or
not a block can be re-allocated or not.
With this commit, the VBD always receive a reference to the whole Snapshots
array and also propagates it this way to the Free Tree.
Ref #4971
- always assign apps/overlay to targets (visible=true/false) to
prevent 0x0 geometry, which is interpreted as close
- add QMenu as exampel to panel button
- use usb-tablet on Qemu
Per default, windows assigned to targets are visible, which can be
changed with the new boolean "visible" attribute. Thus, window can be
hidden without changing their geometry.
Replace the USB session API by one that provides a devices ROM only,
which contains information about all USB devices available for this client,
as well as methods to acquire and release a single device.
The acquisition of an USB device returns the capability to a device session
that includes a packet stream buffer to communicate control transfers
in between the client and the USB host controller driver. Moreover,
additional methods to acquire and release an USB interface can be used.
The acquisition of an USB interface returns the capability to an interface
session that includes a packet stream buffer to communicate either
bulk, interrupt, or isochronous transfers in between the client and the
USB host controller driver.
This commit implements the API changes in behalf of the Genode C API's
USB server and client side. Addtionally, it provides Usb::Device,
Usb::Interface, and Usb::Endpoint utilities that can be used by native
C++ clients to use the new API and hide the sophisticated packet stream API.
The adaptations necessary target the following areas:
* lx_emul layer for USB host and client side
* Linux USB host controller driver port for PC
* Linux USB client ports: usb_hid_drv and usb_net_drv, additionally
reduce the Linux tasks used inside these drivers
* Native usb_block_drv
* black_hole component
* Port of libusb, including smartcard and usb_webcam driver depending on it
* Port of Qemu XHCI model library, including vbox5 & vbox6 depending on it
* Adapt all run-scripts and drivers_interactive recipes to work
with the new policy rules of the USB host controller driver
Fixgenodelabs/genode#5021
This patch contains the mobile variant of Sculpt OS, which evolved
at the genode-allwinner repository until now. In consists of the
following parts:
- gems/src/app/phone_manager plays the role of the sculpt manager
- sculpt/phone-linux allows for test driving the mobile
variant on base-linux
- gems/src/app/dummy_modem mockup of a modem's behavior, used for
GUI development and testing
The parts targeting a specific device (PinePhone) remain local to
the genode-allwinner repository.
To give it a try:
make run/sculpt_test KERNEL=linux BOARD=linux \
SCULPT=phone LOG=core DEPOT=tar
Fixes#5125
- New session interfaces:
- os/include/play_session (for audio playing / mic-input driver)
- os/include/record_session (for audio recording / audio-output driver)
- Mixer at os/src/record_play_mixer providing both play and record services
- Simple waveform player at os/src/app/waveform_player
- Simple audio-signal capturing component at os/src/app/record_rom
- Simple oscilloscpe at gems/src/app/rom_osci (using record_rom)
- Simple test-audio_play for playing raw stereo f32 data
The _gems/run/waveform_player.run_ script illustrates the use of the new
components and interfaces.
Issue #5097
These domains allow for the hosting of plain http and telnet servers
reachable from the outside. The change is designated for the goa
testbed.
Issue #5092
The argument was originally designated to restrict the reach of the
trace monitor but the idea remained unimplemented. It is now superseded
by the use of the trace-session label as trace-subject filter.
Issue #847
The sculpt manager views only launchers in the + menu that are not present in
the runtime already. However, this check was missing when finding the right
launcher on a click event inside that menu. This could cause the manager to
try deploying an already deployed launcher a again (without any effect)
instead of deploying the launcher that was actually clicked.
Ref #5064
This patch mirrors the interface of Sculpt's distant_runtime to the
sandboxed_runtime variant, allowing the configuration of xpos, ypos,
min_width, min_height, opaque, and background color.
Issue #5008
This patch moves the text-editing facility of app/text_area to a
text-area widget as part of the dialog library. This has two benefits.
First, it simplifies app/text_area by using the dialog API. Second, the
editor can now easily be reused by other dialog-API-based applications.
Fixes#5058
The 'Dynamic_array' utility is used by the text_area as internal
representation of text. As a prerequisite step of making the text
editing features generally available as a text-area widget, the
utility must become public.
Issue #5008
Feed the high-frequent fetchurl reports into a list model to speed up
the subsequent evaluation of the data.
Also limit the rate of state reporting during updates to visible changes
in percent such that most fetchurl reports do not cause any UI activity
(status updating) any longer.
This patch noticeably speeds up the installation of complex packages
(i.e., the morph browser) on the PinePhone.
Issue #5038
Component names can be larger than widget IDs, which are capped at 20
characters. To uniquely correlate the component depicted in the graph
with clicks, this patch uses a dedicated graph ID for each runtime
component instead.
Fixes#5034
This patch allows for the interactive assignment of the system-control role
to a new component via the resource dialog. This is useful for integrating
low-level components like the Intel frequency/power monitoring tool.
Fixes#5033
Commit "menu_view: ignore zero-sized widgets in box layout" introduces
zero-sized child widgets as a special case but defined zero-sized as
zero covered pixels (w*h == 0). However, for layouting, a widget with a
non-zero height and zero width is not zero-sized.
This patch refines the zero-size condition such that only widgets with
both zero width and zero height are considered as zero-sized.
It thereby solves the missing display of empty lines in the text_area
component.
This is a follow-up fix for commit "sculpt: apply Dialog API to diag,
panel, and graph", which happened to render the legacy dialogs (network
and settings) inaccessible.
The patch avoids the use of clack seq numbers for the 'popup_opened'
condition (which happens on click, not clack). It also overrides old
click information on the arrival of a new click, avoiding the evaluation
of stale click sequence numbers in distant_runtime.cc. Furthermore, it
reduces the rate of 'Distant_runtime::_try_handle_click_and_clack'.
Issue #5008
On WPA3 encrypted networks the AP picker does not indicate encryption
and does not prompt for a passphrase.
Also indicate an encrypted network when "protection=WPA3", remedying
both issues.
Fixes#5022
This change allows for the hosting of system-management components
in Sculpt's runtime. The special role must be declared either as
<launcher managing_system="yes"> attribute or in the deploy
configuration's <start managing_system="yes"> attribute.
Issue #5009
This patch partially converts the Sculpt manager to the dialog API.
At this stage, both the old utilities and the new dialog API are still
used simultaneously.
Issue #5008
The so-called 'Distant_runtime' implements GUI dialogs via menu_view
components hosted at a distant init instance as opposed to child
components (as implemented by the 'Sandboxed_runtime'). This is
particular the case in Sculpt OS where the sculpt manager is not the
parent of the menu_view instances.
