| 2025-12-03 | x86_64/memory: fix return in scoped_mapping::map | Felix Morgner | 1 | -1/+1 | |
| Previously, scoped_mapping::map returned the start address of the frame. Unfortunately, the initial mapping performed in the bootstrap code maps physical memory starting at 0x0000'0000'0000'0000, which means no fault was triggered. The map function now correctly return the start address of the scoped_mapping's page, which must alway work by definition. | |||||

| 2025-10-29 | x86_64/memory: fix region allocator initialization | Felix Morgner | 1 | -1/+1 | |
| During construction, the memory map was not extracted from the supplied memory information. This lead to a situation in which the allocator would never allocate any frames since it believed that there was no memory in the system. | |||||

| 2025-07-24 | x86_64: implement robust C++ global initialization | Felix Morgner | 4 | -24/+26 | |
| 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. | |||||

| 2025-07-18 | x86_64: don't lose multi boot information pointer | Felix Morgner | 1 | -2/+2 | |
| Since the transition to a PIE, more registers are required to perform the relative lookups of data references. As part of that change, a subtle mistake was introduced in _start, overwriting the multiboot information pointer that gets handed to kernel by the boot loader in %ebx. | |||||
