Introduce 'spec' subdirectories to outline aspects Instead of holding SPEC-variable dependent files and directories inline within the repository structure, move them into 'spec' subdirectories at the corresponding levels, e.g.: repos/base/include/spec repos/base/mk/spec repos/base/lib/mk/spec repos/base/src/core/spec ... Moreover, this commit removes the 'platform' directories. That term was used in an overloaded sense. All SPEC-relative 'platform' directories are now named 'spec'. Other files, like for instance those related to the kernel/architecture specific startup library, where moved from 'platform' directories to explicit, more meaningful places like e.g.: 'src/lib/startup'. Fix #1673

hw: introduce kernel/user address space split * introduces central memory map for core/kernel * on 32-bit platforms the kernel/core starts at 0x80000000 * on 64-bit platforms the kernel/core starts at 0xffffffc000000000 * mark kernel/core mappings as global ones (tagged TLB) * move the exception vector to begin of core's binary, thereby bootstrap knows from where to map it appropriately * do not map boot modules into core anymore * constrain core's virtual heap memory area * differentiate in between user's and core's main thread's UTCB, which now resides inside the kernel segment Ref #2091

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 Patch and use makefile of NOVA microkernel to avoid duplicated (and outdated) makefile in Genode Furthermore, this patch adds support for using NOVA on x86_64.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

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.

# Avoid wasting almost 4 MiB by telling the linker that the max page size is
# 4K. Otherwise, the linker would align the text segment to a 4M boundary,
# effectively adding 4M of zeros to each binary.

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.

base/mk: include sub specs from BASE_DIR Originally, the spec files for less specific SPEC values were include via the 'select_from_repositories' function. This implies that BASE_DIR must always be present in the list of 'REPOSITORIES'. Otherwise the spec files won't be found. By explicitly including sub specs from '$(BASE_DIR)/mk', we lift this restriction.
