Question asked by Kartheek NS on May 31, 2017

We use iMX6 Solo CPU for our product with other technologies like this:

User interface application is based on QT and we use EGLFS plugin.

Use Yocto platform with device tree as recommended by NxP.

 

As we know, iMX6 Solo provides 2 GPUs: GPU3Dv5 (GC880) and GPU2Dv2 (GC320). In the linux kernel device tree, we have both drivers enabled. Can you help to understand following details ?

 

1. How to exactly know, which GPU is actually used in our target ?

2. We do not see interrupts irq_2d and irq_3d when we look at /proc/interrupts. What is the reason for this ?

 

We are in a phase to migrate from iMX6 Solo to SoloX. The GPUs in Solo and SoloX are different and hence we are doing this evaluation to understand if there is any Display performance difference when same application is used on Solo and SoloX.
