DCI USB 3.0 Debug Class,要加此其硬體上須如何配合等等
- 首先就是Platform 需要支援, 再來就是需要將待測機台DCI debug相關的token 開啟(BIOS & ME)
- 相關token可參考DOC#626623
- Debug 部分通常是用來針對CPU hard hang的現象(因為此時BIOS port 80h debug log通常會抓不到東西)或是用以觀察CPU C state , 若是BSOD則建議使用 Windbg 進行分析比較有效率
而CPU hard hang通常比較發生在CPU ES sample 階段, QS CPU後的階段通常比較少遇見 - CCA (藍盒子)價格部份之前是390美金 需要再另外確認
