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 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: 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

Linker script rework

`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

Defines refactoring in msr module

New cpuid model uses instead of old in some msr definitions. 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

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
