etnaviv-gpu 134000.gpu: MMU fault status 0x00000002 on i.XM6 Quad Plus

[Luís Mendes]

Hi Lucas,

Thanks for the info.

I'm using the latest source code from that git repo. I did select the
unstable-devel branch and I did the repo cloning in June, so that commit is
for sure included as well as the last one which was in May 2017,

http://git.arm.linux.org.uk/cgit/xf86-video-armada.git/
commit/?h=unstable-devel&id=a4306d971717a2d3ea855d08c5667e02403b84fe

I've checked the files individually and all the commits are included.

PS: Sorry for the repeated email message, but my first reply didn't go to
the mailing list, despite I was convinced I had done a reply to all...

Regards,
Luís
