Instead of using an additional thread in each Session_component of a
block server, which uses the generic block component and driver classes,
replace it with signal dispatchers.
Ref #113
With 64K stack size, when doing 'make core' in noux on base-hw, the main thread
of /libexec/gcc/arm-elf-eabi/4.7.2/cc1plus runs into a stack overflow during
the compilation of core/main.o . Thus raise the stack size to 128K.
fix#964
The previously used RAM 0x0..0x10000000 was just an alias for
0x70000000..0x80000000. Qemu provides up to of 768 MB RAM with the
correct -m argument. This RAM is located at 0x70000000..0x90000000 and
0x20000000..0x30000000. At least the noux_tool_chain scripts are
happy to have that much RAM.
ref #964
For PBXA9 qemu adjusts provided RAM chips to the -m arg. Thus we
filter user values and force value that enables all chips that Genode
expects to be available. Not doing so leads to inexplicable errors.
ref #964
Makeinfo versions greater 5 treat an @itemx that isn't preceeded by an @item
not as warning anymore but as error. The GCC version 4.7.2 that is used by
noux currently triggers this error multiple times. This commit adds a patch
to 'make prepare PKG="gcc"' that avoids the use of @itemx without preceeding
@item. As GCC versions greater than 4.8 should fix this problem by themselves
this should be seen as temporary quick fix.
ref #964
At least with base-hw, the endless loop at the end of the fork
parent slows execution of the fork child dramatically. Using
libc function pause() is a cleaner solution anyways.
ref #964
When using the initial SP of a main thread for the UTCB
startup-argument, fork_trampoline in libc_noux gets broken.
The function expects the SP to be initialized already in contrast
to the _start function in crt0.s that is called for processes that
are not forked. As the main-thread UTCB is located at the same virtual
address for every PD anyways, we can circumvent this problem by
defining it statically.
ref #964
Struct Msg was introduced due to the handling of pagefaults
and interrupts via synchronous IPC. Its only purpose was to provide
the message type in front of the typed message. Now pagefaults and
interrupts are handled via signals and struct Msg is not necessary
anymore.
ref #958
If the script is executed with an obscure path (e.g.,
'../tool/autopilot'), just taking the argv0 string fails. Therefore, the
file path is now normalized prior to the directory detection.
This patch enables experimental QML support in Qt5.
Only the QtQuick plugin is available yet.
Currently runs best on Linux and has some problems on NOVA and Fiasco.OC.
Fixes#979.
Replace the static lock with the file descriptor lock because recursive
calls of p{read,write} would result in a deadlock when using multiple
libc-plugins at the same time.
Fixes#948.
