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 Patch and use makefile of NOVA microkernel to avoid duplicated (and outdated) makefile in Genode Furthermore, this patch adds support for using NOVA on x86_64.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 2012-06-06 08:19:48 +00:00			`CC_MARCH ?= -m64`

Fix binary size for 64bit Every 64-bit binary is effectively 4M too big currently [0]. The GNU linker ld aligns the text section of the binary to the maximum page size. On i386 the default section alignment is fixed typically to 4K. Avoid wasting mainly 4M on x86_64 by telling the linker the max page size to be 4K.

Prevent silly text-segment alignment on all platforms We set 'ld -z max-page-size' to 4KiB to prevent the linker from aligning the text segment to any built-in default (e.g., 4MiB on x86_64 or 64KiB on ARM). Otherwise, the padding bytes are wasted at the beginning of the final binary. 2015-06-25 15:52:25 +00:00			`LD_MARCH ?= -melf_x86_64`
