NVIDIA Maxwell GPU Support On Nouveau Still Requires More Work
While the Maxwell-based GTX 900 series graphics cards are rumored to be launching in the weeks ahead, the GTX 750 Maxwell graphics cards on the open-source "Nouveau" Linux driver still need some more work before they'll play nicely when not using NVIDIA's proprietary Linux driver.
For NVIDIA Maxwell support within the open-source driver there's basic support within recent Linux kernel releases, the user-space code for Maxwell has landed within Nouveau's NVC0 Gallium3D driver, and there's xf86-video-nouveau support using GLAMOR. With the GLAMOR-required acceleration for Maxwell, the Nouveau DDX depends upon the built-in GLAMOR of X.Org Server 1.16 and newer (rather than the earlier independent GLAMOR acceleration library). With Ubuntu 14.10 now having X.Org Server 1.16 and is running the Linux 3.16 kernel (though with my tests for this Maxwell trial I already switched to Linux 3.17 Git), I pulled in the latest Mesa 10.4-devel packages and other updated components via the Oibaf PPA On Ubuntu 14.10.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
