🌗 我為 Linux 核心貢獻的第一個修補程式
➤ 從虛擬化開發的「三重錯誤」中，習得 Linux 核心的細節與修補之道
✤ https://pooladkhay.com/posts/first-kernel-patch/
作者在開發 Type-2 虛擬機器管理程式（Hypervisor）的過程中，深入探討了 x86 架構中任務狀態段（TSS）的運作機制。為了實現虛擬化，作者需透過 VMCS 結構管理主機與客體的狀態，卻在處理虛擬 CPU 切換時遭遇了嚴重的系統崩潰。經過長時間的排查，他發現問題源於一段從 KVM 測試程式碼複製而來的邏輯，其中的符號擴展（sign-extension）錯誤導致記憶體位址存取異常，進而引發致命的「三重錯誤」（Triple Fault）。這段艱辛的除錯過程最終促成了他對 Linux 核心提交的第一個修補程式。
+ 這篇技術細節滿滿！處理 x86 底層架構時，這種隱蔽的符號擴展問題確實極難追蹤，向作者致敬。
+ 學習虛擬化的最好方式就是親手從零開始寫一個，雖然中間會崩潰無數次，但這些經
