The media player has been traded for the persistent storage topic
because the latter one naturally builds upon the just recently added
file-system interface. Furthermore, we defer the live CD until July as
we realized that we first need to overhaul low-level components such as
USB before the new live system can be expected to work as intended.
modexp512 and rc4-md5 code were missing for x86_64. The files are now
generated on openssl-prepare and will be used when building for x86_64.
Fixes#224.
By now the gmp-library works builds on x86/32bit only. The mpfr library
depends on gmp, so make both library dependent on the corresponding platform
variables. Look at the discussion of issue #135.
Use terminals for LOG output of L4Android scenario, as well as a terminal
session for the Linux terminal. Now everything can be used interactively
on one screen: the Linux/Android framebuffer, the Linux console, and the
LOG-output of L4Linux.
Introduce process global spin-lock for Cap_index's reference-counter
to avoid non-atomic increment/decrement of the counter. Here, we don't
use a static Spinlock object, because it's constructor wouldn't be
initialized before used for the first time.
The following fixes partly solve the problems triggered by the noux stress
test introduced by nfeske in issue #208.
* The check whether a capability exists in the Cap_map, and its insertion,
has to be done atomically
* While removing a capability it is looked up in the Cap_map via its id,
check whether the found capability pointer is the same like the looked up,
otherwise the wrong capability gets freed
* When a local capability is un- resp. marshalled, only the local pointer
gets transfered, not the redundant capability id
* Introduce several assertions and warnings to facilitate debugging
Some source files do not build with -O0 due to conflicting register
allocation and inline assembler constrains. We enforce optimization (O2)
for these files.
Also, I reduced the noise from warning messages induced by lazy handling
of "assignment discards ‘const’ qualifier" and "passing argument from
incompatible pointer type" in third-party sources.
This patch implements a simple Qt-based media player which is actually a
graphical user interface for the SDL-based 'avplay' media player from
'libav'. It starts 'avplay' as a child and shows its graphical output in a
'QNitpickerViewWidget'. The widgets for controlling the player state send
the according keyboard and mouse input events to 'avplay'.
The 'qt_avplay' player supports the following configuration options:
<mediafile name="..."/>
-> name of the media file to play
<framebuffer_filter name="..." ram_quota="..."/> (may appear multiple times)
-> name of a framebuffer filter service to filter the video output
Fixes#222.
This commit contains the initial port of OpenSSL to Genode. It certainly
needs some more work to get things straight - it compiles fine but does
not work because of a NULL pointer exception.
Noux/net adds network functionality to noux. Currently most basic
network related system calls including 'accept', 'bind', 'connect',
'listen', 'recv', 'send', 'shutdown', and 'socket' are implemented by
wrapping lwip's network functions.
At the moment noux/net is rarely usable, though it is possible to
use netcat to send a message to a netcat server which listen on a
given port in noux/net.
With this patch the SDL-based 'avplay' media player, which is part of
'libav', can be built. The run script expects a media file named
'mediafile' in the 'bin' directory.
Fixes#216.
The new 'dde_linux' repository will host device drivers ported from the
Linux kernel. In contrast to the original 'linux_drivers' repository,
'dde_linux' does not contain any 3rd-party source code. To download the
Linux kernel source code and extract the drivers, execute the 'make
prepare' rule of the top-level Makefile. The initial version of the
'dde_linux' repository comes with an USB driver. The porting methodology
follows the path of the Intel GEM port. Instead of attempting to provide
a generic Linux environment that works across drivers, each driver comes
with a specially tailored DDE.
The DDE consists of Genode-specific implementations of Linux API
functions as declared in 'lx_emul.h'. Most of these functions are
dummies that must merely be provided to resolve dependencies at the
linking stage. They are called by unused code-paths.
As of now, the USB driver support UHCI, EHCI on the x86_32 platform. I
exposes USB HID devices and USB storage devices via Genode's input-session
and block-session respectively.
The USB driver is accompanied with two run scripts 'run/usb_hid.run' and
'run/usb_storage.run'.
The Lua runtime library is built in two variants: ANSI C and C++. The
C++ provides all Lua API function with C++ linkage and uses C++
exceptions instead of setjmp/longjmp for protected execution of Lua
chunks.
The ported version of Lua is 5.1.5.
This commit adds a terminal_log component, and a run-script which demonstrates
its usage. The terminal_log component provides the LOG service, and prints
every log-output prefixed by the session-label via a terminal-session.
The new 'genode_envp' variable declared in '_main.cc' allows libc
plugins to supplying custom environment pointers to the main function.
This is needed by 3rd-party software such as GNU make, which expects the
environment pointer as third argument of the main function.
