<pre>I have a DCE3 (RS880) and a monitor which supports RGB quantisation.
before executing the EDID test the values are
radeon_encoder->output_csc = RADEON_OUTPUT_CSC_BYPASS
frame.quantization_range = HDMI_QUANTIZATION_RANGE_DEFAULT
then it executes the EDID test
if (drm_rgb_quant_range_selectable(radeon_connector_edid(connector))) {
if (radeon_encoder->output_csc == RADEON_OUTPUT_CSC_TVRGB)
frame.quantization_range = HDMI_QUANTIZATION_RANGE_LIMITED;
else
frame.quantization_range = HDMI_QUANTIZATION_RANGE_FULL;
} else {
frame.quantization_range = HDMI_QUANTIZATION_RANGE_DEFAULT;
}
and the monitor loses sync and displays a blank screen.
Should the code test both the EDID and output_csc != BYPASS before attempting
the range change?</pre>
