Early Benchmarks Of AMDGPU DRM-Next Code For Linux 4.10

For those curious if the AMDGPU DRM driver changes that are queued in DRM-Next for Linux 4.10 will bring any performance changes, here are some early numbers.

This week I carried out some fresh benchmarks using Linux 4.8.7 stable, Linux 4.9 Git as of this week, and the DRM-Next kernel as of this week that carries the AMDGPU changes queued so far for the next kernel version. In terms of the AMDGPU changes for Linux 4.10, see AMDGPU In Linux 4.10 To Have Better Power Management, New VM Manager.

For these Linux 4.8 vs. 4.9 vs. DRM-Next benchmarks, I was using Mesa 13.1-dev Git this week from the Padoka PPA for the newest user-space driver components. A Radeon R9 Fury and RX 480 were used for testing these three kernel revisions. All tests via the Phoronix Test Suite.



There isn't really any real performance improvements to see with this tentative Linux 4.10 AMDGPU code, but at least no real regressions either, at least for the Fiji and Polaris test cards.
