Use git to get recent kernels from github. Adjust NOVA patch to compile
with recent github version. Patch and use makefile of NOVA microkernel
to avoid duplicated (and outdated) makefile in Genode
Furthermore, this patch adds support for using NOVA on x86_64. The
generic part of the syscall bindings has been moved to
'base-nova/include/nova/syscall-generic.h'. The 32/64-bit specific
parts are located at 'base-nova/include/32bit/nova/syscalls.h' and
'base-nova/include/64bit/nova/syscalls.h' respectively.
On x86_64, the run environment boots qemu using the Pulsar boot loader
because GRUB legacy does not support booting 64bit ELF executables.
In addition to the NOVA-specific changes in base-nova, this patch
rectifies compile-time warnings or build errors in the 'ports' and
'libports' repositories that are related to NOVA x86_64 (i.e., Vancouver
builds for 32bit only and needed an adaptation to NOVAs changed
bindings)
Fixes#233, fixes#234
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.
The build system overlays multiple source trees (repositories) such that
they can shadow libraries and include search paths. This patch extends
the shadowing concept to build targets. Furthermore, it streamlines the
build stage for generating library depenencies, reducing the processing
time of this stage by 10-20 percent. Fixes#165.
In the compare_output_to function in the run tool a check was introduced,
whether the given arguments are empty, and if so if the output string is it
too. Without this patch compare_output_to succeeded when the given pattern
was empty but output wasn't. Please refer to issue #162.
In addition to autogen and autoconf, the tool-chain build script
requires ncurses (for building GDB), wget (to download the tool-chain
source code), and texinfo. Let the tool check if these packages are
installed instead of failing later during the build.
