On ARM, the compiler generates calls to memcpy and memset. Most
dynamically linked programs use the libc, which provides these
functions. However, if a dynamically linked program does not use the
libc (e.g., noux/minimal or the new version of cli_monitor), those
symbols remain unresolved. By adding them to ldso's symbol.map, the
dynamic linker will resolve them with the functions of the cxx
library, which is part of the dynamic linker.
Issue #1561
This patch moves the VFS file-system factory to a separate vfs library
that is independent from libc. This enables libc-less Genode programs to
easily use the VFS infrastructure.
Fixes#1561
With this patch, the VESA driver reports the framebuffer width to the
client instead of the visible width This fixes possible distortion
if these widths differ, at the cost that content in the right-most area
might be invisible in such cases.
Issue #1264.
Add a Platform::setup_irq_mode function which enables the IRQ session to
update the trigger mode and polarity of the associated IRQ according to
the session parameters. On ARM this function is a nop.
This change enables the x86_64 platform to support devices which use
arbitrary trigger modes and polarity settings, e.g. AHCI on QEMU and
real hardware.
Fixes#1528.
Because of helping, it is possible that a core thread that wants to
destroy another thread at the kernel is using the scheduling context of
the thread that shall be destroyed at this point in time. When building
without GENODE_RELEASE defined, this always triggers an assertion in the
kernel. But when building with GENODE_RELEASE defined, this might silently
lead to kernel-memory corruption. This commit eliminates the latter case.
Should be reverted as soon as the scheduler is able to remove its head.
Ref #1537
Placement new can be misleading, as we already overload the new operator
to construct objects via pointers to allocators. To prohibit any problems here,
and to use one consistent approach, we can explicitely construct the object
with the already available 'construct_at' template function.

* Introduce a hw specific Address_space interface for protection
domains, which combines all memory-virtualization related functionality
* Introduce a core-specific Platform_pd object that solves all the hen-egg
problems formerly distributed in kernel and core-platform code

Ref #1443
For several basic sessions that core provides default ram quota values
exist in the form of enum values. They are used e.g. by init to deduce
session costs. Unfortunately they were not used when actually establishing
the session, which lead to inconsistencies.
