[PATCH 3.12 144/175] drm/radeon/cik: properly set sdma ring status on disable

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

 



From: Alex Deucher <alexander.deucher@xxxxxxx>

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

===============

commit 7b1bbe883b3ed962ca2be4daf321f318f5091340 upstream.

When we disable the rings, set the status properly.  If
not other code pathes may try and use the rings which are
not functional at this point.
