Hello,
Found that there is a BDW GPU hang bug with iommu enabled in free desktop
Bugzilla since two years ago, and it is still not closed:
https://bugs.freedesktop.org/show_bug.cgi?id=89360
The last duplicated issue is 99964 which was reproduced with linux-4.10. Does
anyone know if linux-4.11

NAK. You're right that these don't actually give us any advantage over

When a CRC comparison error occurs, it is quite useful to get a dump
of both the frame obtained from the chamelium and the reference in order
to compare them.
This implements the frame dump, with a configurable path that enables
the use of this feature.

The frame dump tests provide no additional functionality over CRC tests
and are considerably slower. Thus, these tests should be considered as
poorer duplicates and removed.
