2013-09-23drm/radeon: don't set default clocks for SI when DPM is disabledAlex Deucher1-4/+4
This is a partial revert of c6cf7777a32da874fabec4fd1c2a579f0ba4e4dd. We need to take into account the clk voltage dependencies of the board. Not doing so can lead to stability issues on certain boards if the clks exceed the levels in the dep tables. DPM already takes that into account, so for optimal performance, use DPM.

This patch adds a helper function to fetch the max clock from the voltage clock dependecy tables.

2013-09-11drm/radeon/atom: workaround vbios bug in transmitter table on rs880 (v2)Alex Deucher1-2/+6
The OUTPUT_ENABLE action jumps past the point in the coder where the data_offset is set on certain rs780 cards. This worked previously because the OUTPUT_ENABLE action is always called immediately after the ENABLE action so the data_offset remained set. In 6f8bbaf568c7f2c497558bfd04654c0b9841ad57 (drm/radeon/atom: initialize more atom interpretor elements to 0), we explictly reset data_offset to 0 between atom calls which then caused this to fail. The fix is to just skip calling the OUTPUT_ENABLE action on the problematic chipsets. The ENABLE action does the same thing and more. Ultimately, we could probably drop the OUTPUT_ENABLE action all together on DCE3 asics. fixes: https://bugzilla.kernel.org/show_bug.cgi?id=60791 v2: only rs880 seems to be affected Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org
