Include cmake feature module in the build routine

2026-07-23T10:55:20Z

Add predicate `ifFeatureEnables` that checks feature is define or not, and return accordingly boolean value. Consider some cmake objective targets as features. Populate information to these targets, and provides in particular file `CMakeFeatures.txt`. Cpuid, MSR, ACPI and driver VGA in text mode they are. Signed-off-by: Alexey Gavrilov

Cmake status information output

Reinforce of compiler, C runtime, architecture checks at cmake configuration. Compiler check means continue building at the cmake configure stage only for supported compilers. Use unsupported compiler involves immediate build process stopping. C runtime check means finding of runtime objects. Especially for *crtbegin.o* and *crtend.o* files. Architecture means *ObjectiveProject_ARCHITECTURE* variable is set. That variable configure at toolchain file by default and cannot override if toolchain file is passed.

Cmake build type at the generation stage

2026-03-28T07:55:53Z

Fix in *nasm* files - set architecture bitness. Move compiler flags from *toolchain* file to *requirements target* considering cmake files. This solution allows available of multi-configurations generators to pass compiler options without affecting on single-configuration generators.

Cmake build generator support: toolchain file

Two toolchain files for clang and gcc compilers under x86 platform. Debug flags also passed at the configure time. Signed-off-by: Alexey Gavrilov

Cmake build generator support: build stage

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.

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

Put in cpuid some definitions and declarations

2025-12-11T08:44:00Z

Declarations: `acquireInformation` for two extended cpuid commands. Overloading `operator&` for enum classes in `VersionInfo` structure to get proper bit value. All declarations from ==Cpuid.h== file are define in the corresponding cpp file. Signed-off-by: Alexey Gavrilov
