page_table_walk

Capture the Flag in Physical Memory You've read about paging. The diagrams make sense. Four levels, 9 bits each, page frame, offset. Sure. But then you hit a challenge that requires actually walking page tables, and you realize you don't know it. You know about it. Big difference. What worked for...
