| 2026-09-04 | x86_64/cpu: isolate kernel and IST1 stack | Felix Morgner | 1 | -1/+13 | |
| Previously, the kernel stack was allocated inside the .kernel_bss section, along other uninitialized data. While this works, it assumes that the section will always be laid out with the kernel stack at the top. If that is not the case, the allocated guard page before .kernel_bss would not trigger a #PF since out-of-bounds (overflow) access would quietly overwrite other data in the section, thus potentially corrupting global kernel data. At the same time, there was no separate section (and guard page) for the future #DF exception stack (IST1 in our case). Thus we allocate a section, and a guard page, while we are already modifying the linker script. | |||||

| 2026-03-16 | x86_64: remove stl_* sections for now | Felix Morgner | 1 | -12/+8 | |
| We currently don't really support user mode anymore, since it doesn't integrate well within the architecture. We therefore need no special handling of STL and kstd anymore. | |||||

| 2025-07-24 | x86_64: implement robust C++ global initialization | Felix Morgner | 1 | -31/+9 | |
| Implement a comprehensive mechanism to ensure correct C++ runtime initialization before the kernel main function is called. This replaces the previous, incomplete reliance on an `_init` function. The new design robustly handles both legacy `.ctors` and modern `.init_array` initialization schemes used by the GNU toolchain. A single C++ function, `invoke_global_constructors`, now iterates through both arrays of function pointers to ensure all types of global initializers are executed. | |||||

| 2024-09-17 | build: fix CRT code linking | Felix Morgner | 1 | -6/+6 | |
| CMake used to generate object files with a .obj extension. This appears to no longer be the case. As a fallback, we now match on 'o*' for the CRT code in the linker script. As of now, it is unclear when this change happened. | |||||
