About 2D / 3D graphics using i.mx8x

[YoshihisaSaitou]

Dear Team,

Device: i.MX8QuadXPlus 

OS: Linux 4.9.88

Board:i.mx8QuadXPlus MEK

I use i.mx8x to evaluate graphics. So, there is one problem. I want to synchronize the drawing completion with Vsync of the display.(e.g. tearing)  I heard that this can not be done, but is it true?

If it can not be synchronized, I want to draw 60 fps. Is there a way to do it? I do not want to use eglSwapInterval ().

Best regards,

Yoshihisa Saito

You can check if Vsync signal is on using GPIO loopback (with setting SION bit).

Have a great day,
Victor
