[PATCH 3.12 034/197] drm/radeon/cik: use a separate counter for CP init timeout

[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 370ce45b5986118fa496dddbcd7039e1aa1a418f upstream.

Otherwise we may fail to init the second compute ring.
