  • R9 Fury Performance Gains With Linux 4.5-rc2? I'm Not So Lucky

    When reading this morning of "double or quadruple the framerates that I got with RC1" for an R9 Fury owned by a Phoronix reader, I immediately set out to run some R9 Fury benchmarks on Linux 4.5-rc2 compared to my 4.5-rc1 results last week and compared to Catalyst. I also did the same for an R9 285 Tonga on AMDGPU as well for reference purposes.

  • AMDGPU ACP Support Called For Merging Still Into Linux 4.5

    While the Linux 4.5 kernel's merge window ended more than one week ago, it looks like the AMDGPU driver may get a late feature arrival: ACP support.

    ACP is the Audo Co-Processor support found in new AMD APUs/SoCs. AMD developers had been working on the support for several months while the audio and power management related ACP code landed during the Linux 4.5 merge window. With that code now mainlined, AMD's Alex Deucher is looking to land the ACP driver support into the AMDGPU DRM driver.

  • The Intel Mesa Driver Has Gotten Faster Since Switching To NIR

    Eduardo Lima of Igalia spoke this weekend at FOSDEM about the work done over the past year on switching the Mesa Intel i965 back-end to using the NIR intermediate representation.

    The presentation by this developer covered GLSL IR vs. NIR, the Intel shader pipeline, what NIR is all about, and more. NIR is the new Mesa intermediate representation that was initially designed by a high school student. Besides Intel's interest in NIR, Freedreno and VC4 Gallium3D drivers have also been actively interested in this IR.

Ubuntu 16.04.2 LTS Delayed Until February 2, Will Bring Linux 4.8, Newer Mesa

If you've been waiting to upgrade your Ubuntu 16.04 LTS (Xenial Xerus) operating system to the 16.04.2 point release, which should have hit the streets a couple of days ago, you'll have to wait until February 2. We hate to give you guys bad news, but Canonical's engineers are still working hard these days to port all the goodies from the Ubuntu 16.10 (Yakkety Yak) repositories to Ubuntu 16.04 LTS, which is a long-term supported version, until 2019. These include the Linux 4.8 kernel packages and an updated graphics stack based on a newer X.Org Server version and Mesa 3D Graphics Library. Read more
