Guys have you actually looked at the following line ? Aperture size is 268435456 MiB -- That is 256 TiB !!!
That's rather impossible amount if you ask me. So there's either a bug in IGT's gem_aperture_size() or one of the two ioctls (I915_GEM_CONTEXT_GETPARAM I915_GEM_GET_APERTURE) that it uses.
With a couple of print statements you should be able to quickly track the exact offender. Good luck !
Yes, we saw it. The bug is reported to IGT (not to DRM/Intel). We propose the test should skip.
I just checked on our IVB platform with 32 GB of memory. Looks like we would need now 2 TB.
