[igt-dev] [PATCH igt 0/2] msm+lib: Add test for buffer mapping permissions

[Rob Clark]

From: Rob Clark <robdclark at chromium.org>

First patch just splits out a couple of helpers from igt_sysfs so they
can be re-used.  Second patch adds a test which locates the address of
a given buffer, and verifies (depending on expected permissions) that
writes and/or reads trigger an iova fault rather than succeeding.

Rob Clark (2):
  igt: Split out I/O helpers
  msm: Add test for kernel buffer permissions
