Title:
  intel_reg_dumper crashed with SIGABRT in __libc_start_main()

Status in OEM Priority Project:
  New
Status in OEM Priority Project trusty series:
  New
Status in “intel-gpu-tools” package in Ubuntu:

Status in “intel-gpu-tools” source package in Trusty:
  Fix Committed

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..
