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
Previously this was not done before Thread_base::start(..) in
base-hw as it was not needed to have a valid cap that early. However,
when changing the affinity of a thread we need the cap to be valid
before Thread_base::start(..).
ref #1076
Express that the target binary files depend on the generated files not
the source files. The old expression seems to confuse Make, which then
logs a bogus error like the following
COMPILE Runtime/common/err/errmsg.o
genode-x86-g++: error: Runtime/common/err/errmsg.cpp: No such file or directory
genode-x86-g++: fatal error: no input files
compilation terminated.
make[2]: *** [Runtime/common/err/errmsg.o] Error 1
make[1]: *** [virtualbox-runtime.lib] Error 2
