Previously, only Invalid_dataspace, Region_conflict, and Out_of_ram were
handled for both allocate and attach with the same handlers. However,
both operations can also throw Out_of_caps and for all exceptions during
attach, the dataspace must be freed again whereas this is not the case
when the exception occured during allocate.
Issue #2953
Instead of retieving the information about the underlying platform from
the configuration, check the running kernel from the platform_info. This
commit removes the undocumented "acpi" config attribute.
* Make target binaries independent of board SPECS
* Name binaries of one architecture unambigously
* Extend include path to match board specifics
* Adapt run-scripts to use the right binary

With the new fact that plain time values are always 64 bit unsigned, the
timestamp type is never bigger than the plain time type. Therefore, a code path
in the curr_time interpolation that treated this condition is not neccessary
anymore.
Ref #3208
This enforces the use of unsigned 64-bit values for time in the duration type,
the timeout framework, the timer session, the userland timer-drivers, and the
alarm framework on all platforms. The commit also adapts the code that uses
these tools accross all basic repositories (base, base-*, os. gems, libports,
ports, dde_*) to use unsigned 64-bit values for time as well as far as this
does not imply profound modifications.

Issue #3111
remove_range may deny to the job on memory pressure or insane ranges,
which ends up in an endless loop when the Avl allocator is in destruction.
Since the Avl gets destructed, solely the memory free up is of importance,
not the correct range adjustments during remove_range.
Track the dataspaces used by attach and add handling of flushing VM space
when dataspace gets destroyed (not triggered via the vm_session interface).
Issue #3111
Handles corner case when addr + size becomes exactly 0. Before the commit
the function returned that sum is not part of the range, which is wrong.
Issue #3111
The old inline assembly provided two output operands that were afterwards
combined for a return value. However, the second output operand isn't
necessary when using the "Acquiring a Lock" example-code of the ARM manual
"Barrier Litmus Tests and Cookbook". This saves two logical operations
per acquisition try. Additionally better documentation is now provided.
Fixes#1292
This patch adds the items necessary for building Genode components with
stack protection enabled, but it is not initialized at runtime. They are
provided at the moment as a convenience and do not implement a security
feature.
Fix#3066
If a component is being destroyed just before it calls `exit()` at its
parent, the `exit()` call causes an `Ipc_error` exception, which leads to
an `abort()` loop with repeated error messages, because `abort()` calls
`exit()` too. Catching the exception in `Expanding_parent_client::exit()`
avoids this problem.
Fixes#3228
* Introduces pending_signal syscall to check for new signals for the
calling thread without blocking
* Implements pending_signal in the base-library specific for hw to use the
new syscall
Fix#3217
The "schedule_post_signal_hook" method of the Genode::Entrypoint class
is problematic because the signal hook can be scheduled and replaced
multiple times during the signal dispatch cycle. Add an alternative to
this method with "register_io_progress_handler" and the "Post_signal_
hook" class with "Io_progress_handler". The difference being an
"Io_progress_handler" may be registered once during the lifetime of an
entrypoint to prevent arbitrary libraries from replacing a pending hook.
The "register_io_progress_handler" remains as a deprecated API, and is
now invoked for every I/O signal received and only for I/O signals
rather than for any signal.
