2025-12-20Linker script refactorAlexey Gavrilov1-10/+18
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 <alexey.gavrilov@mail.com>
2025-12-20Linker script reworkAlexey Gavrilov4-59/+77
`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 <alexey.gavrilov@mail.com>

2025-12-11Put in cpuid some definitions and declarationsAlexey Gavrilov2-311/+110
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 <alexey.gavrilov@mail.com>
2025-12-01Refactoring cpuid model interactionAlexey Gavrilov6-365/+286
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 <alexey.gavrilov@mail.com>
