The error message given to the 'errx()' function does not always contain a
'\n' character. Adding 'printf("\n")' ensures that the message appears on
the log console.
Fixes#1103.
Reserve first bit in bit allocator for main thread of context allocator and
remove special cases in context allocator. Without the reservation there is
is one context outside the context area allocated.
Fixes#1100
The do statement ensures the macros to generate just one expression that
is compatible with any programming construct. The concrete bug was
if (cond)
PDBG(...);
else
...
which was expanded to
if (cond)
if (DO_PDBG)
Genode::printf(...);
else
...
This is obviously wrong as the *else* branch is then connected to the
second *if*.
* Core_mem_allocator: implement Range_allocator interface
* Core_mem_allocator: allocate with page-granularity only
* Use slab allocators in core where meaningful (e.g. dataspace objects)
Fix a use-after-free bug concerning the use case where the config
of the init process changes dynamically. The childs' services were not
removed from the corresponding Service_registry properly.
Fixes#1094
When an object derived from Genode::Connection is copied we had
strange issues. An example is that the first RPC invocation works
correctly but the second one blocks or even delivers incorrect data.
We can avoid this issue if the object is always passed by reference.
Ensure this by deriving from Genode::Noncopyable.
The processor scheduler can determine without much overhead wether
the currently scheduled client becomes out-dated due to the insertion
of another client. This can be used to safe inter-processor interrupts
when a remote insertion doesn't imply an update of the currently
scheduled client.
fix#1088
At least with the ARM generic interrupt controller, inter-processor interrupts
are edge triggered and banked for all source processors. Thus it might be
possible that such an interrupt gets triggered redundantly until the targeted
processor is able to grab the kernel lock. As we're only interested in making
a processor recognize accumulative updates to its scheduler, we can omit
further interrupts if there is one pending already at the targeted processor.
ref #1088
This is needed as soon as we do inter-processor interrupts to
inform a processor about a remote modification in its scheduling plan.
In this case we can not explicitely decide wether to reset timer
or not. Instead we must decide it according to the choices of the
scheduler before and after the modification.
ref #1088
This patch removes the 'Framebuffer::Session::release()' function from
the interface to make the mode-change protocol consistent with the way
the Rom_session interface handles ROM-module changes. That is, the
client acknowledges the release of its current dataspace by requesting a
new dataspace via the 'Framebuffer::Session::dataspace()' function.
Fixes#1057
