The minimal-footprint Ada runtime for implementing library-like
functionality in SPARK is now called "spark" runtime.
The full Ada runtime for entire components written in Ada and using the
libc as glue to the underlying system will move to the world repository
as "ada" runtime.
Issue #3144
Also added a report_rom for USB devices and let the driver report like
in a real scenario. Can also be used for debugging by setting
verbose="yes" in report_rom.
And most importantly: use the same size everywhere.
Note, this commit also configures the stack size of noux-process threads
to 64 KiB independently of the CPU architecture. The reason is the
increased stack usage because of the additional argument space in
Execve_child_env in syscall(SYSCALL_EXECVE), which crafts a child
environment on stack for the creation of the new child.
Fixes#3145.
As we don't execute the acpi_drv on Muen, we have to supply a static
'acpi' info as boot module. This is normally done by the
base/run/platform.inc include. However, when using base-hw-muen kernel
from a depot archive - as done by modern run scripts like
depot_download.run - the platform.inc magic is not applied.
This patch enhances the src archive of base-hw-muen with a mechanism
that creates a pre-defined acpi info at the bin directory via an
artificial src/acpi/target.mk file. This way, the static acpi ROM ends
up as boot module when importing the base-hw-muen archive into a
run script.
* Increase the CMD length to accomodate the limit of the wpa_supplicant
* Fix case where multiple SSIDs with 32 bytes are used
* Use Expanding_reporter for accesspoints report
Fixes#3139.
The 'run_genode_until' procedure only called 'run_power_on' to reset
the target machine. That works will with the softreset module, which
is used by all x86-based test system but falls short regarding ARM
boards. The way those boards are connected requires turning the power
off and on for a complete cycle.
On a Lenovo ThinkCentre M57p, the system locks up when the UHCI controller
BIOS handoff (disabling bit 4 in the LEGSUP register) for the controller
with PCI BDF 00:1d:2 is attempted before the handoff for the controller
with BDF 00:1a:0.
Fixes#3138
This patch replaces the former prominent use of pointers by references
wherever feasible. This has the following benefits:
* The contract between caller and callee becomes more obvious. When
passing a reference, the contract says that the argument cannot be
a null pointer. The caller is responsible to ensure that. Therefore,
the use of reference eliminates the need to add defensive null-pointer
checks at the callee site, which sometimes merely exist to be on the
safe side. The bottom line is that the code becomes easier to follow.
* Reference members must be initialized via an object initializer,
which promotes a programming style that avoids intermediate object-
construction states. Within core, there are still a few pointers
as member variables left though. E.g., caused by the late association
of 'Platform_thread' objects with their 'Platform_pd' objects.
* If no pointers are present as member variables, we don't need to
manually provide declarations of a private copy constructor and
an assignment operator to avoid -Weffc++ errors "class ... has
pointer data members [-Werror=effc++]".
This patch also changes a few system bindings on NOVA and Fiasco.OC,
e.g., the return value of the global 'cap_map' accessor has become a
reference. Hence, the patch touches a few places outside of core.
Fixes#3135
The new method allows for the construction of a meta-data object inside
the reserved space of the allocator's meta data. It thereby alleviates
the need to copy the meta data object (via the assignment operator) as
done by the traditional 'metadata' setter method. This, in turn, allows
one to use non-copyable objects (like objects with constant member
variables) as meta data.
This patch moves the removal of the signal context from the
'_platform_finish_dissolve' to the '_platform_begin_dissolve'
method. This is needed because the removal involves taking
the signal-registry lock. The latter must adhere the same
locking order as the code path used for signal delivery.
Fixes#3109
Move the allocation of the session packet buffer into a subclass that is
constructed before the File_system RPC object. This allows the buffer
allocation to be wrapped in a constructor/destructor class and clearly
accounted for.
Fix#3134
The situation where a 'Session_policy' is constructed for a label with
no matching policy is in almost all cases a configuration problem.
A diagnostic message eases pin-pointing such mistaks. By adding the
message to the 'Session_policy', servers don't need to manually handle
the exception to provide diagnostic information. This simplifies the
server code in many components.
In less interactive mode, the run script doesn't give up on missing test
archives but instead removes the corresponding tests and marks them "missing".
This mode avoids total failure of a platform in automated test infrastructures
when only a few archives are missing.
Fixes#3120
The former 'Genode::Timed_semaphore' mechanism is moved to the private
part of the two remaining users, namely dde_rump and the libc. Note
there are now two private copies of 'timed_semaphore.h'. This should be
regarded as an interim step until the use of this mechanism is removed
from both users.
This patch also cleans up the mechanism from legacy Genode API calls and
global side effects (alarm-thread singleton). The test/timed_semaphore
is now located at the libports repository as it now tests a mechanism of
the libc. The former timed_semaphore library is no more.
Fixes#3121
Store all files generated by moc and rcc in the application's build
directory to prevent the use of unfinished generated files for other
applications built at the same time.
Issue #3115
It can happen that a keyboard gets plugged in and 'led_connect()' is
called while the keyboard LED of another keyboard is just being updated
(and the registry is locked).
Fixes#3118
After a certain number of tests, presumably some resource in core is exceeded
and loading the successive test fails. This quickfix looks out for the
characteristic Core error and then reboots to avoid that all successive tests
are marked as failed.
Since the timer and timeout handling is part of the base library (the
dynamic linker), it belongs to the base repository.
Besides moving the timer and its related infrastructure (alarm, timeout
libs, tests) to the base repository, this patch also moves the timer
from the 'drivers' subdirectory directly to 'src' and disamibuates the
timer's build locations for the various kernels. Otherwise the different
timer implementations could interfere with each other when using one
build directory with multiple kernels.
Note that this patch changes the include paths for the former os/timer,
os/alarm.h, os/duration.h, and os/timed_semaphore.h to base/.
Issue #3101
This patch improves the appearance of the leitzentrale by eliminating
the (hardly visible) decorations from the GUI and graph views, and by
animating the motion of the graph position. The latter is meant to
remove the stuttering effect when the graph's size changes (and
re-centered).
