[KMDOD] How to access DPCD and EDID through DP AUX channel? #975
HI
I am trying to access DPCD and EDID through DP AUX channel. I found an API from WDDM. (https://learn.microsoft.com/en-us/windows-hardware/drivers/display/what-s-new-for-windows-10-display-and-graphics-drivers)
So, I add callback function in KMDOD sample driver.
But I can only get "GUID_DEVINTERFACE_I2C" and "GUID_DXGK_MIPI_DSI_INTERFACE" without "GUID_DXGK_DP_INTERFACE". Do I miss some settings?
Following is my system information:
This monitor connect to PC with DP cable.
Any suggestion is welcome! Thanks in advance.
