Bug Description

[Impact]
An error dialog will be shown after user login to the desktop environment.
The error is :

The intel_reg_dumper raise SIGABRT on Intel ValleyView Gen7 [8086:0f31] platform.

Bumping intel-gpu-tools to 1.7 as SRU is unrealistic, and backporting new hw support didn't fix it, so the easiest way to work around this issue is to not abort() when it fails to detect the chip gen related register maps. This should prevent core dumps and the crash reports.

[Test Case]
This issue can be reproduced by running the command:

# sudo intel_reg_dumper
Gen2/3 Ranges are not supported. Please use unsafe access. (Core dump)

[Regression potential]
None really, it just won't dump core which hardly anything relies on..

@Timo

Will it be back ported to trusty?

Yes, I've just uploaded a version to trusty-proposed that makes intel-reg-dumper not abort() when it checks the supported register map. That should prevent crashes which is all that can be backported..

Hi Timo, can you update the bug description with the SRU template? Also I'd like to know why removing the abort() call makes sense, because in the 1.7-1 version that call is still present. Is the abort() call the right way to handle that code path?
Thanks,

Timo Aaltonen (tjaalton)
