Substitute 'swpb' (swap byte) instruction with 'ldrexb/strexb', because 'swpb'
needs to be enabled explicitly by the kernel, which is done by neither HW or FOC.
When disabled, 'swpb' will cause an undefined instruction exception.
Issue #1048
If opening a report session fails (for example because of invalid
session arguments) and an exception is thrown during the session
construction, the report would wrongly keep the enabled state.
By moving the assignment of the state after the construction,
the report stays disabled as it should be.
This patch improves the focus handling by updating the menubar each time
the user clicks on a different view, even the old and new view belong
to the same session.
Check that in every round really all threads are alive on all CPUs. It
happened that only the first round was ok (all alive) and in the next rounds
some were dead. Unfortunately the test claimed to be successful.
The destructor of the Area object uses invalid caps which results in
a wanted abort of the process on nova. This is mainly the case in forked
process in noux.
Within the central security unit of the i.MX53 SoC, one can set protection
level of various DMA bus master requests, distinguishing them between normal,
and secure access. Although, the access level was meant to be set correctly,
the enumeration values that denoted the kind of access were incorrect. Thereby,
until now every DMA requests was set as being secure. This commit corrects
the enumeration values, and sets all DMA operations as being unsecure, accept
from the graphical subsystem which is controlled by the secure world only.
Thanks to Andrea Barisani and Andrej Rosano from Inverse Path for discovering
this bug, as well as the hardware limitation!
The timed semaphore supports a minimum timeout of 10 ms and logs a
warning if the timeout is lower than the minimum. To prevent the
warning, we limit timeouts to >= 10 ms.
Adding this function eases the implementation of realloc based on
'Libc::Mem_alloc'. Note that this allocator is not used by libc's
default malloc implementation but it is useful for customized C
runtimes, e.g., for the runtime of VirtualBox.
This function provides a way to request the size of an previously
allocated block. It is useful to to ease the implementation of realloc
functionality based on Allocator_avl.
This information is useful if 'libc-common.inc' is included from
another repository, i.e., for building stripped-down libc variants
tailored to an individual application.
