SDL uses the Audio_out session in streaming fashion. For this reason
the audio might be played with delay of at most the queue size. To
mitigate the effect we synchronize the tail pointer to the current play
pointer when the PlayAudio() function is called by SDL for the first
time.
Fixes#1612.
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.
Physical CPU quota was previously given to a thread on construction only
by directly specifying a percentage of the quota of the according CPU
session. Now, a new thread is given a weighting that can be any value.
The physical counter-value of such a weighting depends on the weightings
of the other threads at the CPU session. Thus, the physical quota of all
threads of a CPU session must be updated when a weighting is added or
removed. This is each time the session creates or destroys a thread.
This commit also adapts the "cpu_quota" test in base-hw accordingly.

This patch adds const qualifiers to the functions Allocator::consumed,
Allocator::overhead, Allocator::avail, and Range_allocator::valid_addr.
Fixes#1481
There are lots of places where a numeric argument of an argument string
gets extraced as signed long value and then assigned to an unsigned long
variable. If the value in the string was negative, it would not be
detected as invalid (and replaced by the default value), but become a
positive bogus value.
With this patch, numeric values which are supposed to be unsigned get
extracted with the 'ulong_value()' function, which returns the default
value for negative numbers.
Fixes#1472
Drivers like SD-Card, platform, AHCI, and framebuffer are specified as Exynos5
compliant. But they are at least not compliant with Odroid-XU although this is
Exynos5. Thus, prevent tests that rely on such drivers when building for
hw_odoid_xu. Furthermore, make previous Arndale regulator/consts.h,
uart_defs.h, and some Board_base enums available to all Exynos5 builds to
enable at least building the drivers.
Fixes#1419
With the new run tool, there is no more is_qemu_available function. However,
some scripts still try to use it because only frequently used scripts were
updated by now. The commit replaces the function calls with the new
'have_include power_on/qemu' check.
