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.
Fixes#786Fixes#1133
This has to be used during shared object creation and destruction because global
lists are manipulated. We cannot use the 'Elf_object::lock' here because there
may be jump-slot relocations during object initialization.

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.
Fixes#1351
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.
Fixes#1337
Declaring the SP804 0/1 module and its interrupt to be non-secure prevents the
secure Genode from receiving the interrupt and hence the timer driver in the
secure Genode doesn't work.
Fixes#1340
Some downloads are available via HTTPS only, but wget < 3.14 does not
support server-name identification, which is used by some sites. So, we
disable certificate checking in wget and check the validity of the
download via SIG or SHA.
Fixes#1334.
The commit uses a fixed kernel branch (r8), which fixes a caching bug
observable in the Genode host. The quirk detecting the circumstance in the
timer service is obsolete now and is removed.

The commit
- fixes the syscall bindings for using portal permissions
- revokes PT_CTRL permission after pager in core set local badge name
- revokes PT_CTRL permission after server entrypoint code set local badge name
Fixes#1335
This fix configures TTBRs and translation-table descriptors as if we would use
SMP although we don't to circumvent problems with UP-configurations.
This fix should be superseded later by full SMP support for the VEA9X4.
ref #1312
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
synchronization.
Fixes#1311.

- assign mvm->pm_ops at beginning of function iwl_op_mode_mvm_start.
iwl_mvm_mac_setup_register() uses mvm->pm_ops, but it is called
before this field is set to a valid value.
- disable call to function iwl_mvm_prepare_multicast.
This function leads to a pagefault, as it aspects a list of multicast
addresses, but the list is empty as it is not generated by this port.
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.
fix#1102
As soon as helping is used, a thread may also be in a blocking state when its
scheduling context is ready. Hence, the state designation SCHEDULED for an active
thread would be pretty misleading.

If the debug branch of the nova kernel is used, following messages are printed

The context of timer are now inserted correctly and the actual timer
triggering the exection of each context is always programmed if the
head of the timer list changes.
Fixes#1326.
The jiffies are only updated on each round of scheduling the runnable
tasks. We have to schedule the current task that executes the sleep
call to update the jiffies count and thereby preventing the task from
entering an endless loop when using a statement like
'while (!time_after(jiffies, now + timeout)) { msleep(1); }'.

Instead of probing all device on the PCI bus just look for devices
matching PCI_CLASS_NETWORK_OTHER. This fixes issues with other devices
on the PCI bus, e.g. the GPU, when access their extended config space.

Due to commit "run: relax IP power plug recognition + serial EOF",
when piping the serial command through 'tr', some characters might
get buffered, thereby preventing some run scripts to finish correctly.
This commit removes the 'tr' hack. Instead, to circumvent the 'expect'
problem, which kills under special conditions spawned childs used to
obtain serial line content, whenever EOF of the serial command is
recognized during the boot phase, the child process gets re-spawned.
Setting explicit routes for Nitpicker's 'Framebuffer' and 'Input' sessionsi
avoids ambiguities if a Qt application provides these services, too.
