Cmake build generator support: build stage

2026-03-27T07:03:55Z

Multi-target architecture implementation: each root source code directory presents the one *INTERFACE* target to it's subdirectory subtargets that link only as *STATIC* library. For instance, *arch* directory presents *Architecture* target then *Architecture* target has *CPUID*, *IO*, *PORT* and etc. dependencies Exact order of linking targets is: boot.o CRTIBUNDLE CRTNBUNDLE. Sequence destruction cause to UB. Please to pay attention to this. TODO - Debug information - Build type - Toolchain file - Image creation - Build by WinGW compiler on Windows platform (optional) Signed-off-by: Alexey Gavrilov

Global variables initialization implementation

2025-12-20T12:39:05Z

User implementation of C runtime library objects (`crti.s` and `crtn.s`) for initialization (termination functionality are ignored). Changing files order passed to the linker. Rough order is: boot.s crti.o crtbegin.o other-link-objects.o crtend.o crtn.o Signed-off-by: Alexey Gavrilov

Linker script refactor

2025-12-20T08:56:06Z

In general this update touching sections for initialization and destruction of global variables. DISCARD sections added (.fini and .comment) and particular sections (.ctors, .dtors, .init, .fini) moved into more common sections (.rodata and .text) accordingly. This decision allows to save a some RAM. Signed-off-by: Alexey Gavrilov

Linker script rework

2025-12-20T07:16:47Z

`memory.ld` is a architecture-dependent ld config provides some general symbols which every `memory.ld` config must assign and memory regions associated with each output section. 'linker.ld' config file presents segments configuration. Multiboot section filling move in the 'linker.ld' file. Recommendation for further patches: controlled logic implementation for multiboot version and header/entries in build configuration tool (CMake or make). For instance, multiboot version and video mode selection through variable passing in build system: `cmake ... -DMULTIBOOT_VERSION=2 -DMULTIBOOT_VIDEO_MODE=TEXT_VIDEO_MODE` or 'export MULTIBOOT_VERSION=2; export MULTIBOOT_VIDEO_MODE=TEXT_VIDEO_MODE'. Then build system do proper filling of `.multiboot` section depends on passing variables. Signed-off-by: Alexey Gavrilov

Refactoring cpuid model interaction

2025-12-01T14:40:49Z

Patch for support CPU identification feature. Model smash on two pieces: platform-independent and dependent accordingly. The first obtains architecture details from CPU by special registers or execute instruction and filling proper structure. The second piece needs for more universality to use in independent code. Currently, platform-independent part supports only x86 cpuid(0h,01h) leafs. Signed-off-by: Alexey Gavrilov
