[PATCH 3.11 017/272] drm/radeon: adjust TN dpm parameters for stability (v2)

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

 



3.11.10.1 -stable review patch.  If anyone has any objections, please let me know.

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

From: Alex Deucher <alexander.deucher@xxxxxxx>

commit 958b84fb3bef193198538b5c5902fa687cc8363f upstream.

Adjust some of the TN dpm settings for stability.  Enabling
these features causes hangs and other stability problems
on certain boards.

v2: leave uvd dpm enabled
