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

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
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 It is now superseded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 platform driver needs additional 2MB of RAM for managing IO page
tables (root table and context tables) that are shared among sessions.
genodelabs/genode#5002
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
This patch enhances Sculpt with the ability to detect user inactivity
for driving a screensaver by combining nitpicker's hover and focus
reports with a timer.
Issue #4950
The bulk of the driver code now lives in the 'dde_linux' repository,
which is available on all platforms, from where it can be referenced by
other repositories.
The 'wifi_drv' binary was delegated to a generic harness that includes
all configuration and management functionality shared by all wireless
device driver components, e.g., the wpa_supplicant. The code of the
device driver emulation environment is located in 'src/lib/wifi'. It
is referenced by the platform-specific driver library that resides in
the corresponding platform repository. The runtime configuration needs
to point the driver to proper driver library.
The platform-specific library is in charge of orchestrating the contrib
source utilized by the driver as well as providing the 'source.list'
and 'dep.list' files. It must include the generic library snippet
'repos/dde_linux/lib/wifi.inc' that deals with managing the emulation
environment code.
The 'repos/dde_linux/src/drivers/wifi/README' file contains more
detailed information on how to deploy the driver.
Issue #4861.
The screenshot trigger displays a little red dot at the upper-left
corner of the screen. When touched or clicked-on, it generates an
artificial key-press-release sequence for the print key and disappears
for one second. In this time, a separate screenshot component can handle
the print key by capturing the screen without the red dot appearing in
the saved picture.
Although we do not have the full ACPI information parsed yet, to
announce non-PCI devices derived from the ACPI tables, the device
description of the assumed devices is now integral-part of pci_decode.
Formerly, the information was gained separatedly as boot-module, whereby
we lost synchronization in between ACPI/PCI parsing, BIOS handover, and
PS/2 emulation code already acting.
The platform driver configuration is missing the required 'info'
attribute that allows the 'vesa_fb_drv' to map the proper I/O
memory address of the framebuffer. In addition the driver requires
at least '2' more CAPs, so raise the quota to '110'.
Fixes#4668.
This patch reflects both the pci_decode results and the platform
driver's aggregated device information in Sculpt's /report/drivers/ in
the form of pci_devices and devices files respectively.
Until now, the /config/system ROM was not handled by the sculpt manager
but solely managed by the user. Its main purpose was the ability to
reset or power-down the machine by manually modifying the 'state'
attribute. However, down the road, we'd like to enable the sculpt
manager to drive this state, e.g., to implement the multi-staged
loading of drivers, or to drive suspend-resume states.
The support such scenarios, the 'system' state has been moved from
/config/system to /config/managed/system.
The quota adjustments prevent the leitzentrale's decorator from running
out of RAM, and allow the nitpicker GUI server to preserve buffer
content during resize (reducing flickering artifacts) when using a
screen resolution up to 2560x1440.
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.
Issue #4448
By assigning CPU budgets, base-hw's priorities come into effect.
Even though the chosen values are rather guessed than informed, they
yield a visibly improved responsiveness on the Pinephone.
* Switch from the legacy usb_host driver to the new PC version
in recipes and automated tests
* Update documentation snippets
* Remove outdated, unused usb_rndis run-script
Fixgenodelabs/genode#4416
To make room for the re-newed usb_host_drv basing on Linux 5.14 and
the re-newed lx_kit/lx_emul we have to move the depot recipe and
consistently name the old drivers with a legacy_ prefix.
