Norman Feske a0abb093ed Remove output-section fill from linker scripts
The linker scripts use to fill alignment gaps within the text section
with the magic value 0x90909090, which correponds to the opcodes of four
nop instructions on x86. This patch removes this value because it
apparently solves no problem. If, for some reason (e.g., due to a dangling
pointer) a thread executes instructions within alignment paddings, NOP
instructions are not any better than any other instruction. The program
will eventually execute the instructions after the padding, which is
most likely fatal. It would be more reasonable to fill the padding with
the opcode of an illegal instruction so that such an error can be
immediately detected. That said, I cannot remember a single instance,
where the fill value has helped us during debugging.

Even if the mechanism served a purpose on x86, it is still better to
remove it because it does not equally work on the other architectures
where the linker scripts are used. I.e., on ARM, the opcode 0x90909090
is not a NOP instruction.

Alexander Boettcher 25eec75ad8 vbox: be less verbose in vmx_invalid exit cases
Be less verbose regards warnings caused by vmx_invalid exits - which triggers
on T400 more often because it has no Unrestricted Guest support. This leads
to lot of log messages so that the test does not succeed in time. Additionally,
the script is adjusted to check for some output to
exit earlier if something went wrong.

Stefan Kalkowski 2380fc442f ahci: avoid to reinstantiate backend driver
Instead of fixing the missing dynamic facilities of the AHCI driver
backends for x86 and Exynos5, just avoid to create/destroy the backend
for every new connection, but always use one and the same object.
The AHCI drivers need to be re-written anyway, see issue #1352 for instance,
we can make it more robust for the dynamic case then.

Martin Stein 9a4a0448be hw vea9x4: remove trustzone support
When building Genode for VEA9X4 as micro-hypervisor protected by the ARM
TrustZone hardware we ran into limitations regarding our basic daily
testing routines. The most significant is that, when speaking about RAM
partitioning, the only available options are to configure the whole SRAM
to be secure and the whole DDR-RAM to be non-secure or vice versa. The
SRAM however provides only 32 MB which isn't enough for both a
representative non-secure guest OS or a secure Genode that is still
capable of passing our basic tests. This initiated our decision to
remove the VEA9X4 TrustZone-support.

Martin Stein be7d5b4827 hw: use context-area base that is ok for VEA9X4-TZ
On VEA9X4-TZ, the context-area overlaps with the virtual area of the
text, data and bss. However, we can't simply change the link address as
the core image (used physically respectively 1:1 mapped) needs to be in
this particular RAM-region as it is the only one that can be protected
against a VM. Thus I've moved the context area to a place where it
shouldn't disturb any HW-platform.

Martin Stein d31492040c hw: fix race on pager-object dissolve
The HW-kernel, in contrast to other kernels, provides a direct reference
to the pager object with the fault signal that is send to the pager
activation. When accessing this reference directly we may fall into the
time span where the root parent-entrypoint of the faulter has alredy
dissolved the pager object from the pager entrypoint, but not yet
silenced the according signal context.  To avoid this we issue an
additional 'lookup_and_lock' with the received pager object. This isn't
optimal as we don't need the potentially cost-intensive lookup but only the

Martin Stein d704563453 hw: helping on IPC
On base-hw, each thread owns exactly one scheduling context for its
whole lifetime. However, introducing helping on IPC, a thread might get
executed on scheduling contexts that it doesn't own. Figuratively
spoken, the IPC-helping relation spans trees between threads. These
trees are identical to those of the IPC relation between threads. The
root of such a tree is executed on all scheduling contexts in the tree.
All other threads in the tree are not executed on any scheduling context
as long as they remain in this position. Consequently, the ready-state
of all scheduling contexts in an IPC-helping tree always equals the
state of the root context.
