Linux Firmware Debug Kit (LFDK)

講題：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。
