    It's only ~300 LoC and is a very significant improvement comparing to its size, Can't it be back-ported to older kernels?

        Nice improvement. I would wish it is possible to get this in the 4.19 kernel, because it will become the next LTS Kernel.

          Too late really with DRM-Next effectively being closed now for new 4.19 features.

            We need more Vulkan benchmarks, because thats almost an 11% boost in fps by my math. Pretty significant. Shame it's missed the merge window for 4.19.

              Nice to hear this! This should close the gap to nvidia by another good margin

                I'm pretty sure the original number was a regression, and the subsequent fix for the regression number is the baseline, and the next number is the improvement.

                  I will wait for the test from Phoronix.
