drm/amd/display: Use kvzalloc for potentially large allocations

2018-05-09T20:16:13+00:00

Allocating up to 32 physically contiguous pages can easily fail (and has failed for me), and isn't necessary anyway. Reviewed-by: Harry Wentland Signed-off-by: Michel Dänzer Signed-off-by: Alex Deucher

drm/amd/display: Fix regamma not affecting full-intensity color values

2018-04-12T18:56:21+00:00

Hardware understands the regamma LUT as a piecewise linear function, with points spaced exponentially along the range. We previously programmed the LUT for range [2^-10, 2^0). This causes (normalized) color values of 1 (=2^0) to miss the programmed LUT, and fall onto the end region. For DCE, the end region is extrapolated using a single (base, slope) pair, using the max y-value from the last point in the curve as base. This presents a problem, since this value affects all three color channels. Scaling down the intensity of say - the blue regamma curve - will not affect it's end region. This is especially noticiable when using RedShift. It scales down the blue and green channels, but leaves full-intensity colors unshifted. Therefore, extend the range to cover [2^-10, 2^1) by programming another hardware segment, containing only one point. That way, we won't be hitting the end region. Note that things are a bit different for DCN, since the end region can be set per-channel.
