This commit introduces the new `Component` interface in the form of the
headers base/component.h and base/entrypoint.h. The os/server.h API
has become merely a compatibilty wrapper and will eventually be removed.
The same holds true for os/signal_rpc_dispatcher.h. The mechanism has
moved to base/signal.h and is now called 'Signal_handler'.
Since the patch shuffles headers around, please do a 'make clean' in the
build directory.
Issue #1832
Prevents the annoying warning about
WARNING: Image format was not specified for 'bin/test.img' and probing guessed raw.
Automatically detecting the format is dangerous for raw images, write operations on block 0 will be restricted.
Specify the 'raw' format explicitly to remove the restrictions.
If attached ROM dataspaces are not valid after update(), code that uses
these ROMs produces
void Genode::Volatile_object< <template-parameter-1-1> >::_check_constructed() const [with MT = Genode::Attached_dataspace]: Deref_unconstructed_object
In scenarios where the config ROM is loaded from a report ROM or any
other non-static ROM, config might try to access an invalid dataspace
capability. This patch prevents the component from aborting in this
case.
Fixes#1914
This commit replaces the stateful 'Ipc_client' type with the plain
function 'ipc_call' that takes all the needed state as arguments.
The stateful 'Ipc_server' class is retained but it moved from the public
API to the internal ipc_server.h header. The kernel-specific
implementations were cleaned up and simplified. E.g., the 'wait'
function does no longer exist. The badge and exception code are no
longer carried in the message buffers but are handled in kernel-specific
ways.

Issue #1832
If ports need preparation in order to execute a run script, use the
knowledge about the actual genode directory to suggest a command to the
user that can be directly copied to the command line.
Rust relies on atomic builtins, which are not implemented in libgcc for
ARM. One is implemented in rust, which is sufficient to get the
current rust test to run.
Issue #1899
Check if the binary pointer is valid before attempting to lookup the
symbol. Shared objects with unresolved symbols and missing depencies,
e.g a library that references 'errno' but is not linked against libc,
will now produce an error message when they are loaded by the dynamic
linker.
Fixes#1904.
This patch moves details about the stack allocation and organization
the base-internal headers. Thereby, I replaced the notion of "thread
contexts" by "stacks" as this term is much more intuitive. The fact that
we place thread-specific information at the bottom of the stack is not
worth introducing new terminology.
Issue #1832
The interfaces linux_cpu_session, local_capability, linux_dataspace,
linux_native_pd are mere implementation necessities. They are meant for the
internal use by the framework only. So it is appropriate to move them to
base/internal/.
Issue #1832
On seL4 and L4/Fiasco, we employ a simple yielding spinlock as lock
implementation. Consequently these base platforms used to have a
simplified header. However, since the regular cancelable_lock has all
the member variables needed to implement a spinlock, we can simply use
the generic header on those two platforms too, just leaving some other
parts of the generic header unused. So at API level, the difference is
not visible.
Issue #1832
By moving the stub implementation to rm_session_client.cc, we can use
the generic base/include/rm_session/client.h for base-linux and
base-nova and merely use platform-specific implementations.
Issue #1832
This patch establishes a common organization of header files
internal to the base framework. The internal headers are located at
'<repository>/src/include/base/internal/'. This structure has been
choosen to make the nature of those headers immediately clear when
included:
#include <base/internal/lock_helper.h>
