imx8qm linux5.4 GlTexDirectVIVMap cause gpu hangs

huangjacky — Tue, 15 Sep 2020 08:13:39 GMT

Hi:

I use the opengl + GlTexDirectVIVMap as demoApp to display the camera data which is come from max9286.

My demoApp works in imx8qm + linux4.14, however, when I porting My demoApp to linux5.4. I got the error print as below :

Hello huangjacky,

Apparently is not the gpu instead you are playing with non supported resolution camara however further investigation revealed that mxc-isi driver is making cameras not plug and play.

That means, you remove one camera, you wont be able to use the other four until rebooting.

At least this is what happens in my experience. You are not even able to stream with gstreamer if the camera connection is lost once, or unplugged.

Freeze issue still remains a mystery.

Regards
