如何開啟DRM Debug Level
參考資訊：
1. Introduction-to-drm-debug
在CMDLINE啟動參數加入drm.debug=0x6，CMDLINE參數可以在開機選單出現時，按下e鍵做修改或者修改grub.cfg
"Bit 0 (0x01) will enable CORE messages (drm core code)\n" "Bit 1 (0x02) will enable DRIVER messages (drm controller code)\n" "Bit 2 (0x04) will enable KMS messages (modesetting code)\n" "Bit 3 (0x08) will enable PRIME messages (prime code)\n" "Bit 4 (0x10) will enable ATOMIC messages (atomic code)\n" "Bit 5 (0x20) will enable VBL messages (vblank code)\n" "Bit 7 (0x80) will enable LEASE messages (leasing code)\n" "Bit 8 (0x100) will enable DP messages (displayport code)");
P.S. drm.debug=0x6代表開啟DRIVER、KMS訊息
