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
With this patch, functions which execute blocking syscalls on Fiasco.OC
are built with frame pointers to get a correct backtrace shown in GDB.
Also, the backtrace test for a thread currently executing a syscall now
traces the 'Genode::Thread_base::join()' function instead of
'Genode::sleep_forever()', because base-nova has a custom implementation
of 'Genode::sleep_forever()' with a different backtrace than on Fiasco.OC.
Fixes#1061.
Instead of using a special bitfield use a compound of boolean
values for the generic page attributes. To reduce copy overhead,
change the corresponding functions, where Page_flags are used as
arguments, to use references.
This is normally needed in LDSO and was previously done by the LDSO specific crt0.s.
I forgot to keep it during the unification of the different crt0s.
