KEY_UNKNOWN is a collective symbols for all unknown keycodes.
Remapping thus requires iterating through all corresponding codes
instead of only applying the policy to the first match.
Issue genodelabs#4069
This patch increases the RAM quota of the top-level nitpicker instance
to 12 MiB so that resize operations can be buffered for resolutions up
to 2560x1080. It mutes diagnostic messages of the form "Warning: Gui
(...) not enough RAM to preserve buffer content during resize" and
improves the window-resize experience.
With this patch, the user is able to re-gain access to the inspect view
by toggling the inspect button of a file system unrelated to the failed
USB storage device.

Issue #3967
triggers using -O0 with test-libc_integration:
libc_integration/main.cc:146: undefined reference to `std::istream::operator>>(unsigned long&)'
contrib/stdcxx-80f380143250d4f951433876698b54fdac32b95f/include/stdcxx/std/thread:67: undefined reference to `vtable for std:🧵:_State'
Introduce a new _overflowed state variable to indicate whether the
horizontal boundary was reached already and to omit subsequent character
output.
This state is necessary to maintain a valid cursor position at all
times. The _overflowed attribute is reset once the cursor is moved into
a valid position again.
To harmonise the bounds checking for _cursor_pos modifications, the
`constrain()` method was added.
Fixesgenodelabs/genode#4093
Also fixes a bug in `vpa()` and `vpb()` which moved the cursor
horizontally instead of vertically.
The direct execution of application-level code by a watch handler is
troublesome because those handlers are executed at the I/O signal level.
In the concrete case, the watch handler got recursively called because
the handler called _handle_config (application-code), which called the
VFS, which in turn performed a wait_and_dispatch_one_io_signal, which
again invoked the watch handler.
The patch works around the problem by letting the watch notification
trigger the application-level signal for the _config_handler.
Fixes#4091
I created a test program which stresses the interplay between libc,
pthreads and vfs_pipe and may detect regressions.
The program starts a thread that spawns a bunch of workers, sends and
receives data to them through a pipe. When all data of a worker is
collected, the worker is finished (join()) and a new worker is started.
Both the number of bytes sent to the worker and the size of its
answer are random.
Issue #3967
* The device XML information dataspace is only provided,
when the client's policy states `info="yes"`
* The device XM information gets changed to include the
physical resource names (I/O memory and IRQ addresses)
instead of virtual ids and page offset
Fix#4077
As linux drivers may distinguish device configuration by pci subdevice id in
addition to the pci device id, the former must also be used for finding the
matching entry. Otherwise, e.g., the iwlwifi driver might load the wrong
firmware.
Side note: Add break statement to save superfluous iterations after
match was identified.
Fixes genodelabs#4076
This is a follow-up fix for "Streamline platform-device API on ARM".
There is an ambiguity of the 'local_addr' method between the inherited
'Attached_dataspace' and the local declaration, which results in the
double application of the sub-page Range::start.
Issue #4075
This compilation unit contains a global constructor, which violates our
assumption that the libc is free of global constructors on ARMv7.
Specifically, the graphical terminal fails with the following message:
[init -> terminal] Error: Component::construct() returned without executing
pending static constructors (fix by calling
Genode::Env::exec_static_constructors())
[init -> terminal] Error: Uncaught exception of type 'Linker::Fatal'
In this case, the libc-less terminal uses the VFS. The VFS mounts the
ttf VFS plugin. The ttf VFS plugin depends on the libc.
The compilation unit 'arm_initfini.c' can safely be excluded because it
merely initializes the global '_libc_arm_fpu_present' variable, which
is not used by the current version of our libc/libm.
Fixes#4080
This API rework eases the access to memory-mapped I/O registers and
interrupts when using the platform driver. It introduces the notions of
- Platform::Device - one device obtained from a platform session
- Platform::Device::Mmio - locally-mapped MMIO registers of a device
- Platform::Device::Irq - interface for receiving device interrupts
The patch touches several drivers. Some drivers would require a
significant structural change to adopt the new API (e.g., net/virtio,
dde_linux drivers, imx gpio). In these cases, the patch adds
compatibility shims meant to be temporary. In other cases (e.g., imx
i2c), the adaptation was simple enough to carry through.
Fixes#4075
This patch adjusts the matching of the IP address such that the external
IP address is used as opposed the the NAT-local address. It is follow-up
fix of the conversion to the uplink session interface.
Issue #3961
When we allowed symbol resolution during exceptions, we used the shared
object lock to protect ELF object list manipulation (e.g., dlopen,
dclose) when executing exception unwinding code in the linker.
Unfortunately, sometimes libraries that are loaded by 'dlopen' may raise
exceptions in the process, leading to a deadlock within the unwind code.
In order to resolve this, we now protect the object list operations
(i.e., enqueue, removal, iteration) by a separate mutex. This allows
the shared object interface to throw exceptions.
issue #4071
This patch unifies the core-internal 'Mapping' type across all base
platforms.
As one minor downside on seL4, the diagnostic error messages when
observing faults other than page faults no longer print the faulting
thread and PD names.
Issue #2243
These messages pollute the boot log of Sculpt OS when ROM modules are
requested for files of the config fs before the sculpt manager has
created their first version.
When the own cap quota of a client does not suffice for a cap upgrade of
an existing session to a server, the client must issue a cap-resource
request to the parent. This logic was already in place for RAM quota but
was missing for cap quota.
