X-Git-Tag: omap-for-v3.16/fixes-rc4~80^2~4^2 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4366f3b5f5a971cf348c298716b2cb29aab6ef4f;p=pandora-kernel.git drm/radeon: Bypass hw lut's for > 8 bpc framebuffer scanout. The hardware lut's only have 256 slots for indexing by a 8 bpc framebuffer. In 10 bpc scanout modes, framebuffer color values would get truncated to their 8 msb's, thereby losing the extra precision afforded by a 10 bpc framebuffer. To retain full precision, bypass the hw lut in 10 bpc scanout mode. Signed-off-by: Mario Kleiner Signed-off-by: Alex Deucher --- Reading git-diff-tree failed
