Unfortunately, the 'gcc -dumpmachine' magic does not suffice on all
Linux distros, so we just add the well-known paths for i386-linux-gnu
and x86_64-linux-gnu.
Fixes#1694
This patch extends the configuration concept of init with an additional
sub node for the <start> node:
<start name="noux">
<exit propagate="yes"/>
...
</start>
If the 'propagate' attribute is set to "yes", the exit of the respective
child will appear to init's parent as the exit of the entire init
subsystem.
Fixes#1686
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
To correctly delete all IPC gates created via a CAP session, all
capabilities created have to be stored. Otherwise we leak kernel
objects within Fiasco.OC permanently.
Fix#702
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.
Sometimes, the play position in stream is behind the out stream, mostly
because of timing issue. In this case, the mixer will produce invalid
packets which in return will lead to looping on an invalid packet in
the audio_drv.
Issue #1666.
Instead of looping the whole queue, the driver now loops on the first
invalid packet. In any case it will send a progress signal to its
client.
Fixes#1666.
For some platforms (at least hw_zynq on Qemu), the measured time of the
periodic timeout test exceeded the maximum that was previously
calculated without any tolerance. Most likely, this is not a malfunction
of the test subject as the error is pretty small and, of course,
measuring the time produces overhead itself. Introducing a tolerance of
only 0.1% fixes the problem.
Fixes#1599
Instead of returning pointers to locked objects via a lookup function,
the new object pool implementation restricts object access to
functors resp. lambda expressions that are applied to the objects
within the pool itself.
Fix#884Fix#1658
Propagating the user context-pointer from C++ code to the mode
transition assembly doesn't touch any CPU global data. Thus, we can
reduce the in-sync window.
Fixes#1223
Other platforms implement Kernel::Cpu_context stuff in
kernel/cpu_context.cc. On x86_64, it was implemented in
kernel/thread.cc. The commit fixes this inconsistency to the other
platforms.
Ref #1652
The distinction between Kernel::Thread and Kernel::Thread_base is
unnecessary as currently all Hw platforms would have the same content in
the latter class. Thus I've merged Kernel::Thread_base into
Kernel::Thread. Thereby, Kernel::Thread_event can be moved to
kernel/thread.h.
Ref #1652
The Muen-specific PIC implementation provides the irq_occurred()
function which is used to register an IRQ with the PIC upon thread
exception.
The occurred IRQs are stored in a boolean array internally and handed
out to a CPU via take_request().
The driver uses the timer page containing a vector and timer value to
implement the start_one_shot() and value() functions. The timer value
designates the absolute tick count of the next event.
The address of the time page is acquired using the get_memregion_info
Sinfo API function.
The Muen Sinfo API is used to retrieve information about the execution
environment of a subject running on the Muen Separation Kernel.
While the C++ API is defined in sinfo.h, musinfo.h specifies the
internal format of the information stored in the Sinfo pages provided by
the Muen SK. It is a copy of the file contained in the libmusinfo
library of the Muen project. That is the reason why the coding style in
this file differs from the official style.
