Bare Metal Computing X64 Edition

About this book

Most programmers never touch the machine. They live inside frameworks. They trust kernels. They inherit latency, abstraction, and hidden behavior they do not control. And they call that “systems programming.” Bare Metal Computing With X64 — Low Level Coding of Native Instructions is for the engineer who wants authority, not convenience. This book takes you beneath operating systems, beneath drivers, beneath libraries — to the execution model itself. You will learn: How machine instructions are encoded at the binary level How control registers actually govern execution How paging, TLBs, and memory attributes shape real behavior How interrupts, exceptions, and privilege rings truly work How to bring a processor from reset state into 64-bit long mode How to build deterministic systems without an operating system How to design ultra-low-latency, real-time, and hardware-controlled execution environments This is not theory. You will configure descriptor tables. You will program PCI devices directly. You will manage DMA safely. You will measure interrupt latency. You will debug faults without a safety net. You will enforce hardware isolation at the silicon boundary. And you will see how…
