Stone: A new era for Linux's low-level graphics - Part 2

[Posted March 23, 2018 by corbet]

Here's the second part of Daniel Stone's series on recent improvements in low-level graphics support. "The end result of all this work is that we have been able to eliminate the magic side channels which used to proliferate, and lay the groundwork for properly communicating this information across multiple devices as well. Devices supporting ARM's AFBC compression format are just beginning to hit the market, which share a single compression format between video decoder, GPU, and display controller. We are also beginning to see GPUs from different vendors share tiling formats, in order to squeeze the most performance possible from hybrid GPU systems."
