This driver uses the Usb session interface and provides a Block session
to its client. See _repos/os/src/drivers/usb_block/README' for more
information.
Fixes#1885.
From our observations we can tell that the error should not exceed 4%.
However, there is no reasonable explanation by now why the test results
are less stable on these platforms. We have tried several things that
did not lead to an explanation or improvement:
* changing the timing parameters of the scheduler
* switching off SMP
* double-checking the speed of userland and kernel timers
Ref #1805
The test threads previously used a stack size independent from the machine
word width. Qemu was previously configured to provide 64Mb of RAM which isn't
sufficient for x86_64.

Print result error and error tolerance per test result. Use TCL commands
'format' and 'abs'to simplify calculations in the conclusion part of the run
script.

* Provide paravirtualized block API for accessing the second partition
of the block device that is provided by the ESDHC driver.
* Provide paravirtualized serial API for sending log-output over Genodes
serial port.
* Use the latest Linux suggested in the USB Armory Wiki [1] when on USB Armory
while still using the older vendor Linux when on i.MX53 QSB. I.e.,
provide a device tree through RAM and a rootfs through the paravirtualized
block device when on USB Armory while providing ATAGs and Initrd when on
i.MX53 QSB.
* Switch on the LED on the USB Armory when the VMM catches a VM-exception
and switch it off again when as soon as the exception is handled. This
merely show-cases the ability to instrument the LED for such purposes. In an
ideal world, the LED is switched on as long as we're on the "Secure Side"
and switched off as long as we're not.

This patch moves the formerly internal classes of the report-ROM service
to the public location os/include/report_rom/ so that they can be reused
by other components such as the upcoming clipboard.
Instead of holding SPEC-variable dependent files and directories inline
within the repository structure, move them into 'spec' subdirectories
at the corresponding levels, e.g.:
repos/base/include/spec
repos/base/mk/spec
repos/base/lib/mk/spec
repos/base/src/core/spec
...
Moreover, this commit removes the 'platform' directories. That term was
used in an overloaded sense. All SPEC-relative 'platform' directories are
now named 'spec'. Other files, like for instance those related to the
kernel/architecture specific startup library, where moved from 'platform'
directories to explicit, more meaningful places like e.g.: 'src/lib/startup'.
Fix#1673
This scripts starts two Audio_out session clients. These clients
access the soundcard via the mixer. The first client simply streams
a sample file in a loop while the second client generates a click
sound when any key is pressed.
Issue #1666.
If a requested report already exists the request is denied with
Invalid_args.
Further, I dusted the report_rom test and added it to the
autopilot list.
With the introducation of the Audio_in session interface it makes
sense to rename the current available audio drivers. At the moment
only the dde_bsd audio_drv supports Audio_out as well as Audio_in.
The Linux audio_drv only supports Audio_out (there is no demand for
Audio_in support currently) but is renamed nonetheless to make it
easiert to write generic run scripts.
Issue #1644.
The timer driver on X86 needs CPU quota with highest priority as it
frequently has to interrupt the counters to update the PIT.
On ARM this makes no difference in the test results as ARM timer
drivers, once configured, can sleep until the end of the timeouts.
On X86 we raise the error tolerance to 2% (default 1%) to compensate
the error caused by the timer.
Fixes#1621
Printing all errors and the goal values instead of exiting at the first
error allows for faster analysis of problems with the CPU-quota
mechanism.
Ref #1616
The test always succeeded because I forgot to set the error tolerance from
my debugging value 1 back to the correct value 0.01 before commiting the
test.
Ref #1616
Adjust bomb to specify the various hard-coded parameters and set up bomb.run
this way that it manages at our test machine to succeed in the given time.
Issue #1615
Add a test where a locked pointer shall be taken during object destruction.
Moreover, extend the run-script so it runs on different platforms with
"real" timers.
By appending a newline to the generated XML data, we prevent the output
from messing with the command prompt when using 'cat' on a shell.
Futhermore, when using line-buffered output, the trailing newline
ensures that the output gets gets properly flushed.
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.
