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

Thu Nov 2 15:05:38 UTC 2017

Hi,

Wladimir, Fabio: Thanks for pointing out this patch. I have applied the
patch and compiled mesa, but it produced no relevant change regarding the
MMU fault that I am getting. For me it makes sense that it isn't related to
this issue because I am running no 3D applications, just logging in into
the Ubuntu MATE Desktop. Since I am using xf86-video-armada It is expected
that GC320 is the only unit busy, working, during this stage of the desktop
initialization.

Russel, Lucas: The etna-gpu-tools compiled cleanly... I got this log and
some .bin files with the dumps. I have no clue about the GC320 registers as
I have no knowledge about the unit, however I if could get the stack of the
calling process, would be great...
