Subject: [PATCH igt 0/2] msm+lib: Add test for buffer mapping permissions
Date: Mon, 29 Nov 2021 16:43:22 -0800 [thread overview]
Message-ID: <20211130004324.337399-1-robdclark@gmail.com> (raw)
From: Rob Clark <robdclark@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
