Kernel::pause_current_thread can be implemented much simpler and is not
restricted to core threads, in contrast to Kernel::pause_thread which
also benefits from the split and can be moved to core_interface.h.
ref #1101
If an RM fault ends up in any trouble, the faulter remains paused and
the pager activation continues with the next fault. Thus we can print
a warning instead of an error and safe execution time in release mode.
ref #1096
In most cases an error report is not necessary in the kernel as the problem
does not affect the kernel itself but the according user-land context. Thus
we can also do a warning that is not printed in release mode and hence safe
execution time.
ref #1096
As the message "replay: missing dataspace info for ..." occurs multiple times
on every fork, it slows down at least noux_tool_chain_auto with hw_arndale
about 10 seconds. To avoid this overhead in release mode I've turned it into a
warning rather than an error.
ref #1096
Previously for determining wether boot-up succeeded or not, we looked
for a message that is switched off in release mode. Now the kernel
provides a reliable message as soon as initialization is done.
ref #1096
We changed the test hardware and the new one does not support 1400x1050 anymore.
Choose some conservative resolution since this is anyway a auto test nobody
is really looking at the screen output.
The 'tinfo.cc' file needs to get built, because it implements
'std::type_info::operator==(std::type_info const&) const', which
is needed by the 'icu' library on ARM.
Fixes#1109.
If counter drops to 0, the wrap flag is set also. That means we have actually
no wrap around. The patch avoids to add too much time to the elapsed time
variable.
Issue #1106
The generalization of nitpicker's graphic backend changed the interface
of 'Mode::forget', which is a (non-pure) virtual function implemented
by 'User_state::forget'. Unfortunately, the signature change was not
applied to 'User_state::forget' so that the actual implementation was
no longer called. This inconsistency remained unnoticed because there
is a default implementation of the virtual function.
The effect of the omission of the 'User_state::forget' call was a
dangling pointer ('User_state::_pointed_view').
Lesson learned: Always annotate functions with the C++11 'override' when
implementing virtual functions.
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.
