17" UHD 60Hz panel flicker with black screen in Tinylinux OS
I use NV test tool which need to boot in Tinylinux OS. Boot in Tinylinux OS,panel will flicker with black screen regularly in SG mode(Panel edp signal come from intel iGPU),won't flicker in PEG mode(edp signal come from NV dGPU). And this issue won't happen in win10 OS.
Besides,we have test several panel.
Flicker : 17" UHD 60Hz / 15"17" FHD 300Hz
Normal : 15" OLED 60Hz / 15"17" FHD 144Hz (Both SG & PED mode won't flicker)
Do you have any idea what reason cause it?
Platform : CML-H TinyLinux version : 19.08 Intel Gfx driver version : 26.20.100.7584
