The commits adds the same configuration values as supported up to now by
the monolithic usb driver. In contrast to the original, by default all drivers
are started. Disabling a controller type is used by Sculpt, e.g. for OHCI if
running Sculpt inside Virtualbox.
The addition of further keyboard layouts would otherwise pollute the
config/ directory too much.
Caution: When updating Sculpt OS, don't reuse your existing
config/event_filter file unmodified! You need to replace the chargen
includes, pointing to the new location, e.g.,
<include rom="en_us.chargen"/>
<include rom="special.chargen"/>
must be changed to
<include rom="keyboard/en_us"/>
<include rom="keyboard/special"/>
Issue #4055
This patch extends the settings dialog with the ability to select the
keyboard layout between the options that are included in the sculpt
image. The manual configuration is of course still possible by editing
the /config/event_filter directly.
If both the fonts configuration and the event-filter configuration are
managed manually, the settings button and window are not displayed.
Fixes#4055
By sorting the reported output, all consumers of the reports become able
to rely on a deterministic order. For example, the file browser of
Sculpt OS, the launcher menu items, and the depot-selection items will
appear in a predictable order.
Fixes#4054
This patch adds session-routing options to connect components to the
capture/event interfaces of the global nitpicker GUI server or the
leitzentrale GUI server. It thereby enables the implementation of screen
capturing components, remote management tools, or virtual keyboards.
Since those services are very powerful, they are subsumed under the
"hardware" category of the component graph as opposed to the GUI
category, which guarantees the separation of clients.
Fixes#4053
This patch adds 4 priority levels to the runtime subsystem. The highest
priority is used for components that are critical for the operation of
Sculpt, in particular the Leitzentrale GUI. All regularly deployed
components are assigned the lowest priority by default.
With priorities available in the runtime subsystem, this patch flattens
the priority levels at the top-level init to only two levels and
overlays the priority bands of the drivers, leitzentrale, and runtime
subsystems into one priority band. This has three benenfits:
- This change prevents the starvation of the Leitzentrale GUI from a
spinning high-priority driver (issue #3997).
- The change will also ease the hosting of latency-critical components
in the runtime subsystem that are prioritized higher than regular
components, the storage stack, and the network stack.
- The Leitzentrale GUI remains always perfectly responsive regardless
of the workloads deployed from packages. In the previous version,
the runtime graph was sometimes stuttering on high system load.
Issue #4045
This patch avoids the repeated warning "read blocked until lwIP
interface is ready" by printing the message only once. Otherwise,
the log is flooded with those warnings when falkon web browser
is started on Sculpt OS without network connectivity.
In case there is no valid configuration the component used to mute
output by default. This, however, might lead to the assumption that
audio is not working at all. Instead set the master output volume to
50% and the per application volume to 100%.
Fixes#4043.
This patch adds the missing destruction of session-state objects of
local services when closing a session. Because of the missing
destruction, those session-state object remained part of the server
ID space. This becomes a problem once the backing store of the session
state object vanishes, that is when the client child gets removed from
the sandbox. Hence, the removal of a child with an open session to a
local service would lead to the corruption of the server ID space.
This patch adds the missing session.destroy() call.
Fixes#4044
This patch fixes a corner case where a child is destructed while a
asynchronous close request to a sibling server is still pending.
The child immediately discarded the session ID as the end of the
close-session processing, assuming that this ID is never to be needed
again. The session-state continues to exist to handle asynchrous close
protocol with the server.
However, if the child is destructed at this point (before the server
responded to the session request), the destruction of the child would
not cover the discharging of the session state because the session state
was no longer be part of the client's ID space. So once the asynchronous
close response from the server came in, the session state contained
stale information, in particular a stale closed_callback pointer.
The patch fixes the problem by deferring the discarding of the client ID
to the point where the session state is actually destructed. So the
session of a pending close response is covered by the child destructor.
Thanks to Pirmin Duss for reporting this issue along with a test
scenario for reproducing it!
Fixes#4039
- Enable the "platform-level interrupt controller" PLIC on base-hw

issue #4042
This patch triggers the immediate removal of part_block once the
discovery of a fresh inserted USB stick has completed. Without the
patch, part_block was retained until the runtime was reconfigured the
next time for other reasons (e.g., toggling an inspect view). Until the
next reconfituration, part_block tended to stand in the way of directly
assigning the USB device to a VM.
This patch increases the RAM quota of the nitpicker instance for the
leitzentrale to make it suffice for the buffering of content during
resize operations. This fixes a flickering artifact when having an
inspect view open while entering a WLAN passphrase. When the connect
button appears or disappears (depending on the number of written
characters), some parts of the inspect terminal would flicker sometimes.

This way, the redirected env sessions for the CPU burner are no longer
called directly by init. Init stays independent from the behavior of the
CPU balancer.
Issue #3837
Issue #4029
This shim component can be used in case where env sessions of child
(i.e., child's PD session) must be routed to another child of init.
Without the shim, init would directly need to interact with these
sessions and would thereby make itself dependent of the server's
behavior. RPC calls to a server hosted as a child lead to all kinds of
problems such as livelock situations, and putting the robustness of init
at the whim of its child.
With the shim, init merely needs to bootstrap the shim component by
routing the shim's env sessions to core as usual. The server is only
used for the sessions for the actual application hosted atop the shim.

Ref #3961
This patch simplifies the packaging of the base-hw kernel for a given
board, in particular when the board support is hosted as an external
repository such as genode-world. Regardless of where the board-support
is hosted, the content.mk file becomes as simple as:
include $(GENODE_DIR)/repos/base-hw/recipes/src/base-hw_content.inc
The board name is automatically inferred from the path of the src
recipe. The architecture is determined from board/<name>/arch files,
following the pattern of the image_link_address. The attempt to build a
base-hw-<board> binary archive for the wrong architecture is now
gracefully handled by skipping all targets (using the REQUIRES
mechanism).
Besides the improved convenience, the patch results in depot archives
that are much closer tailored to the actual board by omitting files for
architectures that are not used by the board. E.g., the src/base-hw-pc
archive does not contain any ARM-related content.
The patch also restores the package builds for core/bootstrap object
files as a follow-up fix of "base: remove SPEC variables of boards",
which happened to left 'BOARD' undefined in the src archives.

Be more in line with the original host implementation in Qemu and
buffer transfers. Having transfers in-flight helps to smoothen playback
in case other components utilize the CPU.
Issue #4018.
Linux as well as Windows guests want queue to a varying number of
transfers, where each transfer only covers one transaction (iso frame).
The best results were obtained by following that behaviour rather
than queuing multiple iso frames per requests (like is done with OUT
transfers).
The number of requests queued is increased to 32 while the number of
packets per reques is decreased to 1.
Issue #4018.
The contrib code is updated from 2.4.1 to version 5.2.0 and the used

OSes, namely Windows 7, that relied on the NEC xHCI device-model will
not work anymore.
The 'Qemu::Controller' interface was extended by an 'info' method, which
returns the vendor and product ID. This allows for removing the
hard-coded values in the VirtualBox glue code.

* Update the 'packet_size' information with the actual length for
each isoc frame to be able to handle short reads at the client side.
* Copy the whole transfer buffer because the host controller stores
the data at the original offsets, i.e., the buffer is not densely
packed.
Fixes#4018.
The former implemention assumed that the guest physical memory is
mapped continously. This, however, is not true. Writing larger
files to an USB stick with a Windows 10 guest would therefore lead
to data corruption.
The current implementation uses a bounce buffer to copy the data
to and from the guest physical memory and leaves dealing with the
memory mappings entirely up to the VMM.

When the usb_net_drv was introduced in ports/run/netperf.inc, the

netif_start_queue was also a dummy and allowed to be called, we tried allowing
calls to the netif_stop_queue dummy as well which fixed the
netperf_lxip_usb test on x86_64/hw/pc.

The 'environ' pointer is a global variable that must be considered as
part of the application state. It must be copied from the parent to the
child process during fork. Otherwise, a child returning from fork is
unable to access environment variables before invoking execve. The
actual environment variables and their values are already captured
because they reside at the application heap, which is cloned from the
parent. So the copied 'environ' pointer refers to valid data.

The _crt0_start_stack label points to a memory location containing the

but the code only only defines half of those using asm .long statement.
The other half is expected to be 0, which is true when using GNU as.
This is not the case when using clang's integrated as however. Since
_crt0_stack_size is defined inside .text section clang uses 0xd503201f

The code in base-hw/src/bootstrap/platform.cc uses segment flags for
identification purposes. Based on this information the code decides
what to do with each segment. Unfortunately the linker script does
not actually ensure the flags for a specific named segment match
expectations. The code relies on implicit linker behaviour.
This implicit behaviour can vary between linkers. This breaks
arm_v7a base-hw builds linked with LLVM's lld linker. The segment
named "ro" ends up having writeable flag set when using LLD.
This patch ensures that all ELF segments in genode.ld have their
required perimssion flags set explicitly.
Fixes#3988
Clang is generally fine with Genode::List and compiles code using it
without emitting any warnings. There is however one exception. Clang
fails hard when building base-hw/src/core/kernel/object.cc.
This is due to a call to Genode::List::remove made from
Object_identity::invalidate function. The error message clang
produces is:
list.h:96:33: error: 'Genode::List<Kernel::Object_identity_reference>::Element::_next'
is not a member of class 'const Kernel::Object_identity'
_first = le->List::Element::_next;
~~~~~~~~~~~~~~~^
When we look at the declaration of the Kernel::Object class on which
the remove method is called. as expected it does inherit Genode::List:
using Object_identity_list
= Genode::List<Kernel::Object_identity>;
class Kernel::Object : private Object_identity_list
{
...
}
Given the error message we see that List::Element should be resolved to
Genode::List<Kernel::Object_identity>::Element, and not
Genode::List<Kernel::Object_identity_reference>::Element. But how does
clang manage to figure out we're talking about Object_identity_refecence
list here? Well, I admit I don't know the exact steps it takes to arrive
at this conclusion, but it is not entirely wrong. If we take a look at
what Kernel::Object_identity is we'll see:
class Kernel::Object_identity
: public Object_identity_list::Element,
public Kernel::Object_identity_reference_list
{
...
}
Where as one can guess Object_identity_reference_list is defined as:
using Object_identity_reference_list
= Genode::List<Object_identity_reference>;
Long story short Kernel::Object has Genode::List of both Kernel::Object_identity
and Kernel::Object_identity_reference in its inheritance chain and clang
is not really sure to which of those the code refers to in
Genode::List::remove method by using List::Element::.
The fix for this is relatively simple, explicitly state the full type of
the base class the code intends to refer to. Replacing List::Element,
with List<LT>::Element makes the code buildable with both clang and GCC.

Ref #3971
In order to perform a smooth transition from NIC drivers that act only as NIC
session clients to NIC drivers that act only as Uplink session clients, this
commit introduces an intermediate state in which all NIC drivers support both
modes. That said, a NIC drivers mode is now statically determined through a new
optional 'mode' attribute in the drivers <config> tag that can be set to either
'nic_server' (default value) or 'uplink_client'. Reconfiguring this attribute
at a driver doesn't have any effects. Whithout this attribute being set, all
NIC drivers will behave the same as they did before the commit. When set to
'uplink_client', however, instead of providing a Nic service, they request
an Uplink session whenever their network interface becomes "UP" and close the
session whenever their network interface becomes "DOWN".
Ref #3961
Let the NIC router provide an Uplink service besides the Nic service that it
already provided. Requests for an Uplink session towards the NIC router are
assigned to Domains using the same <policy> configuration tags that are used in
order to assign Nic session requests. The MAC addresses of Uplink session
components are _NOT_ considered during the allocation of MAC addresses for NIC
session components at the same Domain. The task of avoiding MAC address clashes
between Uplink session components and Nic session components is therefore left
to the integrator. Apart from that, Uplink session components are treated by
the NIC router like any other interface.
Ref #3961
Adds new Uplink session interface, the corresponding client side (Client,
Connection), and the corresponding API archives. An Uplink session is almost
the same as a NIC session with the difference that the roles of the end points
are swapped. An Uplink client is the one that provides a network interface
(for instance, a NIC driver) whereas an Uplink server is the one that uses
that network interface (for instance, a networking stack).
Therefore, in contrast to the NIC session, MAC address and link state come from
the Uplink client. The link state is reflected through the lifetime of an
Uplink session: The client requests the session only when the link state is
"UP" and closes it whenever the link state becomes "DOWN" again. The MAC
address is transmitted from the Uplink client to the Uplink server as an
argument of the session request.

When holding at least one key or button, the hovering should never
change. In the previous version, this invariant was not enforced,
but the symptoms for eventual inconsistencies were masked by two
checkes: one when generating the hover report, and one when submitting
the leave event. This patch enforces the invariant by suppressing any
change of 'User_state::_hovered' while in dragged state.
Fixes#3973
When idle, the decorator still consumes a bit of CPU time when triggered
by the GUI session's sync signal. This patch installs the sync handler
each time the decorator goes idle.
During position scaling use the location width/height which is the permitted
dimension within the child space, instead of using the whole possible
child space. (Fixup for "init: scale affinity location" Issue #1412)
Thanks to the report by Peter.
* Introduce 'use_arp' configuration flag at the NIC router in order to disable
requesting IP-to-MAC address resolutions via ARP for domains.
* Add automated run/nic_router_disable_arp test to the autopilot that tests
the effect of the new flag
* Document the new flag and the new test in the NIC router README
Fixes#3935
Thise driver supports USB LTE modems for Huawais' ME906s through MBIM
and provides a traditional Nic session. The "control" interface is a
Terminal session, which can be used via libmbim/mbimcli.
issue #3822
This commit restores the diag feature for selecting diagnostic output of
services provided by core. This feature became unavailable with commit
"base: remove dependency from deprecated APIs", which hard-wired the
diag flag for core services to false.
To control this feature, three possible policies can be expressed in a
routing target of init's configuration:
* Forcing silence by specifying 'diag="no"'
* Enabling diagnostics by specifying 'diag="yes"'
* Forwarding the preference of the client by omitting the 'diag'
attribute
Fixes#3962
- Vendor devices add addtional data to the config descriptor, read and
added to the usb session
- allow '0' configuration within the usb session
issue #3822
The usb_hid driver does not need to distinguish between
normal memory and DMA capable memory, since all requests are routed via the
USB raw session to the usb host driver. The default Malloc implementation
implements this distinction, however exposes restrictions on the size of
allocations. As seen now by several USB HID devices, the size of device
driver allocations depend on read out hardware features and can be
larger than we support with our specialized default Malloc implementation.
Since we don't need this functionality, switching to an well
tested allocator (Heap) which can cope with varying sizes of allocation,
we can mitigate the size restriction.
Fixes#3953
* The NIC router now considers, memorizes, and, if configured, reports
multiple DHCP option 6 entries from DHCP replies that it received as DHCP
client
* A DHCP server at the NIC router can now be configured statically with
multiple DNS server addresses to propagate
* The 'dns_server_from' attribute of the DHCP server of the NIC router now
supports the forwarding of multiple DNS server addresses
* The automated run/nic_router_dhcp test tests all the above mentioned new
functionality and reconfiguring it at runtime. The test was added to the
autopilot.
* All run scripts were adapted to fit the new NIC router configuration
interface
Fixes#3952
When reconfiguring the NIC router modifies the information that DHCP clients
received through a DHCP server of the NIC router, the link state of the
correspodning interface has to do a "down-up" sequence. This provides a signal
to the DHCP clients to redo DHCP, receive the new information and update
accordingly.
Fixes#3931
* Introduce CPU quota for driver subsytem (needed by sd_card_drv)
* Introduce CPU quota for runtime subsytem and nic_drv (needed by fec_nic_drv)
* Increase CAP quota for inspect terminal slightly
* Add sculpt packages for imx8q_evk
Fix#3958
* Introduce sculpt-[board] specific package
* Move rtc driver into managed drivers sub-system
* Name nic_drv in a generic fashion in sculpt_manager
* Copy over pc-specific config files only when building for PC
