Linux Firmware Debug Kit (LFDK)

自介：一位喜愛研究電腦硬體操作及作業系統的工程師，目前任職於華碩電腦，從事 Android Phone 之開發。

摘要：
因曾經從事過一陣子 Legacy BIOS 工作，體驗過 BIOS 豐富的 debug 工具。例如一些 BIOS Engineer 所熟悉的 AMI RU，Award ADU 等兩個通用 Debug 程式。以及各家公司內部自行開發的 debug tools，如 e820，Super I/O，I2C tools 等等。但很奇怪的，Linux 上怎麼老是沒什麼可以用來 Debug 的工具程式。尤其對一位 BIOS Engineer (尤其是 Server BIOS) 而言，Linux 也是其很重要的目標平台。如果在 DOS 上出了問題，那有 RU/ADU。如果在 Windows 上出了問題，那有 Windows 版的 RU。那如果在 Linux 上出了問題呢？另一方面對 Embedded Linux Engineer 來說，不斷的重複燒 FlashROM，或是不斷 rmmod/insmod，以及 Remote NFS，雖然可以加速整個 Registers Debug 的流程，但都還是不及有一個通用工具來的方便，可以達到即時修改即時反應的便利。所以就在那樣的時空背景下，也就動手寫了與 AMI RU 介面很相似的 LFDK 這套工具。在這幾年來，帶給了我不少方便，更甚至是飛到大陸客戶端處理問題。然而事過境遷，它已經許久不再改版，故將之釋出為 GPL Open Source Software，與有緣人分享之。
