With this patch, functions which execute blocking syscalls on Fiasco.OC
are built with frame pointers to get a correct backtrace shown in GDB.
Also, the backtrace test for a thread currently executing a syscall now
traces the 'Genode::Thread_base::join()' function instead of
'Genode::sleep_forever()', because base-nova has a custom implementation
of 'Genode::sleep_forever()' with a different backtrace than on Fiasco.OC.
Fixes#1061.
Instead of using a special bitfield use a compound of boolean
values for the generic page attributes. To reduce copy overhead,
change the corresponding functions, where Page_flags are used as
arguments, to use references.
This is normally needed in LDSO and was previously done by the LDSO specific crt0.s.
I forgot to keep it during the unification of the different crt0s.
fix#1077
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!
