Re: i.MX6, Mesa, GLES2, Vivante GC320 + GC880

Hi ,
Thank you but it didn't help.
I remove everything and start from scratch and everything is now building (except u-boot.imx which don't want to install).

1) Are libdrm, kernel-module-imlx-gpu-viv, ... patches/bbappends still needed as EtnaViv's Github[1] says that everything have been upstreamed to drm, mesa and kernel ?
It seems that a great job has been done to avoid the need of extra packages to have 2D/3D acceleration working in mainline trees, so I am now totally lost of what it is really needed or not.

2) I really want a minimum of extra freescale packages because I was so disappointed with i.MX27. So, is the package imx-gpu-viv still needed ?

I am going to test the image and try to enable Qt. I will wait to have a fully working image because trying to switch to kernel 5.0

Best regards,
Gaëtan.
