Intel Ivy Bridge Graphics On The Linux 3.11 Kernel
With the Linux 3.11-rc1 release, it's time now at Phoronix to start benchmarking the Linux 3.11 kernel. The first tests to run over the weekend were of Intel Ivy Bridge graphics, where a few regressions were spotted.
Intel has a lot of DRM graphics driver changes in Linux 3.11. The changes mostly impact current Haswell users as well as working on stabilizing the support for next-generation Atom Bay Trail / Valley View hardware. However, when comparing Linux 3.11 to a Linux Git snapshot (as of Saturday, 13 July), there were a couple slowdowns though for the most part the performance was the same.
The early benchmark results for Intel HD 4000 Ivy Bridge graphics from a Core i3 Ultrabook can be found in 1307158-SO-INTELIVYB33.
Some slowdowns were spotted, but for the most part the OpenGL performance was the same for this Ivy Bridge mobile hardware between Linux 3.10 and the early Linux 3.11 code.
Of more interest will be the Intel Haswell figures and then the immense open-source Radeon DRM driver changes, which are all being benchmarked right now at Phoronix for future articles.
