[PATCH 3.2 017/125] drm/i915: s/DRM_ERROR/DRM_DEBUG in i915_gem_execbuffer.c

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



3.2.61-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Daniel Vetter <daniel.vetter@xxxxxxxx>

commit ff240199b6a3b0bec5ae9b6d26403dad38e8cb19 upstream.

These are all user-trigerable, so tune down their loudness a notch.
For some of these we have i-g-t tests (because they prevent
newly-discovered bugs), without this patches running the test suite
leaves behind a dirty dmesg.
