Instead of trying all PCI devices by a specific PCI driver, now the device or
the device class can be limited to the one actually supported by the specific
driver.
The "strncpy - not implemented" message appeared on the use of libpng.
Even though it did not cause trouble, spilling the log with such
easy-to-fix issues should better be avoided.
Bender fixes the serial output on modern PC hardware. Prior this patch,
it was used only when combined with pulsar. Now, we also use it when
booting via GRUB.
Allocate ever an extra page behind the commandline pointer. If it turns out
that this page is unused, because commandline was short enough, unmap the
memory and put the virtual and physical regions back to the allocator.
Fix#664
With this patch, the 'futex' syscall gets used for blocking and unblocking
of threads in the Linux-specific lock implementation.
The 'Native_thread_id' type, which was previously used in the
lock-internal 'Applicant' class to identify a thread to be woken up,
was not suitable anymore for implementing this change. With this patch,
the 'Thread_base*' type gets used instead, which also has the positive
effect of making the public 'cancelable_lock.h' header file
platform-independent.
Fixes#646.
Revoke the right to set the portal id (aka label) when it is not needed
anymore. Otherwise everybody in the system having a mapping of the portal can
reset the label to something we don't expect.
Issue #667
In base-fiasco, base-foc and base-pistachio, physical memory gets mapped
1:1 to core virtual memory. When the 'Ram_session_component' allocates
physical memory for a client, it zeroes out the corresponding area in
core's virtual address space and then maps the area to the client. If this
area overlaps with core's virtual thread context area (usually at
0x40000000-0x4fffffff), the stack of one or more core threads can get
overwritten.
To avoid this problem, with this patch, the thread context area gets
removed from the physical RAM allocator on these platforms.
Fixes#660.
Without the patch the signal cap was ever transferred to the timer session
when a usleep/msleep was called, even when unneeded. On base-nova this
causes the allocation of new capability indexes which are not freed up.
So the timer service run quickly out of indexes and get out of order...

This happened when I killed one of the genode clients which was
tracked via an expception_handler. In this case the wait4 syscall
returned 0 and the for(;;) was looped eternally. This caused an
100% CPU utilization for the core binary.
Make 'context_area_virtual_base' platform configurable. On Arndale, we
need to move the context area to a location that does not interfere with
the address range of physical memory.
The new terminal_mux server is able to provide multiple terminal
sessions over one terminal-client session. The user can switch
between the different sessions using the keyboard shortcut C-y,
which brings up an ncurses-based menu.
This patch moves the further reusable parts of the terminal into public
header files. It also slightly tweaks the color table to give all colors
a similar brightness level.
