Phoronix: Mesa 11.0 vs. 11.2-devel Tests For Intel Skylake

Given the fairly slow news day due to the holidays this week in the United States, here are some extra benchmarks to share this evening: some Mesa 11.0.2 vs. 11.2-devel Git benchmarks with an Intel Skylake system,..

That's the second article where this has happened. What's the point of the PTS if it can't get the basics right

I guess once again 4K results on Xonotic, but FullHD results advertised

To what are you talking about?

To what are you talking about?

This:

Note the reported P-State governor difference between reboot...

You tried handwaving it away in the article, but it's basically rendering the whole point of PTS moot. These comparisons are useless while this issue continues.

The culprit isn't PTS...

It's not PTS, all PTS does is get the contents of what's shown in the P-State/CPUFreq sysfs. It's straight getting the file contents without any operations or anything on it. It's the P-State driver or whatever it depends upon for determining default governor type that's acting up. If it weren't for PTS, it wouldn't even be known the difference unless manually cat'ing the file each time.

I bought a skylake also and I'm super sad because I can't change the CPU governor.

Did some success to get ``sudo cpupower frequency-set -g performance'' to do something? My cores are at 800MHz instead of 4GHz... It makes it impossible to reliably make music using realtime synthesizers...

It doesn't matter whose fault it is. The bottom line is that your results are not repeatable or a fair comparison.
