Intel Iris Gallium3D controller is working?

[Raudt]

Hello, again here asking questions, first of all thank you all for any help. How to know if the Intel Iris Gallium3D controller is working? As I have read from MESA 20.0 it comes active by default, but is there any way to know if it is really active? I am using Xubuntu 20.04, MESA version 20.0.4, I also have (Skylake)
