[Mesa-dev] [PATCH 0/6] RadeonSI: DCC for displayable surfaces

[Marek Olšák]

Hi,

This series allows enabling DCC for displayable (currently all window)
surfaces depending on the circumstances. There is a heuristic that
determines whether it pays off based on the pipeline statistics query,
because DCC decompression is expensive and can outweigh the benefit
of DCC.

Most of the time this optimization is disabled and it only turns on
in special situations. It has a slightly higher chance to be enabled
on Stoney, because Stoney can't do fast color clears without DCC.
Also on Stoney, consecutive slow color clears turn it on as well.

Please review.

Marek
