toolchain: report missing ports at once Previously, ports that were needed for a scenario and that were not prepared or outdated, triggered one assertion each during the second build stage. The commit slots a mechanism in ahead that gathers all these ports during the first build stage and reports them in form of a list before the second build stage is entered. This list can be used directly as argument for tool/ports/prepare_port to prepare respectively update the ports. If, however, this mechanism is not available, for example because a target is build without the first build stage, the old assertion still prevents the target from running into troubles with a missing port. Fixes #1872

Use NOVA microkernel from github, add 64bit 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 Patch and use makefile of NOVA microkernel to avoid duplicated (and outdated) makefile in Genode Furthermore, this patch adds support for using NOVA on x86_64.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

Disambiguate kernel-specific file names This patch removes possible ambiguities with respect to the naming of kernel-dependent binaries and libraries. It also removes the use of kernel-specific global side effects from the build system. The reach of kernel-specific peculiarities has thereby become limited to the actual users of the respective 'syscall-<kernel>' libraries. Kernel-specific build artifacts are no longer generated at magic places within the build directory (like okl4's includes, or the L4 build directories of L4/Fiasco and Fiasco.OC, or the build directories of various kernels). Instead, such artifacts have been largely moved to the libcache. E.g., the former '<build-dir>/l4/' build directory for the L4 build system resides at '<build-dir>/var/libcache/syscall-foc/build/'. This way, the location is unique to the kernel. Note that various tools are still generated somewhat arbitrarily under '<build-dir>/tool/' as there is no proper formalism for building host tools yet. As the result of this work, it has become possible to use a joint Genode build directory that is usable with all kernels of a given hardware platform. E.g., on x86_32, one can now seamlessly switch between linux, nova, sel4, okl4, fiasco, foc, and pistachio without rebuilding any components except for core, the kernel, the dynamic linker, and the timer driver. At the current stage, such a build directory must still be created manually. A change of the 'create_builddir' tool will follow to make this feature easily available. This patch also simplifies various 'run/boot_dir' plugins by removing the option for an externally hosted kernel. This option remained unused for many years now. Issue #2190

nova: define kernel memory based on system memory Switch to kernel branch, that determines the available system memory during boot time. The overall kernel memory is still static, but during boot time dynamically the amount can be chosen. Following 3 config option exists: CONFIG_MEMORY_BOOT is the amount of kernel memory allocated in the BSS statically - effectively chosen during link time - see linker script. CONFIG_MEMORY_DYN_MIN && CONFIG_MEMORY_DYN_PER_MILL configures the dynamic part of the kernel memory allocation applied during early kernel boot time. CONFIG_MEMORY_DYN_MIN is the amount of memory which should be allocated at least. CONFIG_MEMORY_DYN_PER_MILL defines the amount of the system memory in per mill which should be allocated at most. The overall maximum kernel memory is restricted to ~1G (64bit), due to the chosen internal virtual memory layout. Fixes #2985

Generalize ABI mechanism to shared objects This patch make the ABI mechanism available to shared libraries other than Genode's dynamic linker. It thereby allows us to introduce intermediate ABIs at the granularity of shared libraries. This is useful for slow-moving ABIs such as the libc's interface but it will also become handy for the package management. To implement the feature, the build system had to be streamlined a bit. In particular, archive dependencies and shared-lib dependencies are now handled separately, and the global list of 'SHARED_LIBS' is no more. Now, the variable with the same name holds the per-target list of shared libraries used by the target.
