drm/radeon/cik: properly set compute ring status on disable

2014-03-12T20:20:44+00:00

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.

drm/radeon/cik: stop the sdma engines in the enable() function

2014-03-12T19:53:25+00:00

We always stop the rings when disabling the engines so just
call the stop functions directly from the sdma enable function.
This way the rings' status is set correctly on suspend so
there are no problems on resume.  Fixes resume failures that
result in acceleration getting disabled.

drm/radeon/atom: select the proper number of lanes in transmitter setup

2014-03-06T23:09:52+00:00

We need to check for DVI vs. HDMI when setting up duallink since
HDMI is single link only.  Fixes 4k modes on newer asics.

drm/radeon: silence GCC warning on 32 bit

Building radeon_ttm.o on 32 bit x86 triggers a warning:

Silence this warning by using min_t(). Since cur_size will never be
negative and its upper bound is PAGE_SIZE, we can change its type to
size_t and use min_t(size_t, [...]) here.
