The results in this article contain more NVIDIA GeForce Linux results than what was shared last week when showing how BioShock Infinite runs much faster with the NVIDIA Linux driver than AMD Catalyst. The NVIDIA test line-up today spans from the GeForce GTX 550 Ti Fermi to the newest GeForce GTX 960/970/980 Maxwell graphics cards.
The Linux 4.1 kernel will feature support for Radeon DisplayPort Multi-Stream Transport so that this open-source AMD Linux graphics driver can work with the latest high resolution DP displays and modern laptop docking stations.
For those thinking about potentially running a Linux system with a combination of SSD and HDD so that the solid-state drive would be able to act as a performance cache for commonly used data, BCache and LVM-cache/dmcache are two of the commonly used solutions.
For those interested in LVM Cache or BCache, Fedora developer Vratislav Podzimek has written a lengthy blog post comparing these two hybrid caching solutions for Linux -- including setup procedures and steps for Fedora users.
At the last USENIX/LISA conference, I gave a talk on new Linux performance tools: my open source perf-tools collection. These use existing kernel frameworks, ftrace and perf_events, which are built in to most Linux kernel distributions by default, including the Linux cloud instances I analyze at Netflix.
5.1 also makes many small interface changes, documented in the gallery above. Notification and volume controls have seen improvement, and the OS has been tweaked and polished all over.
In addition, 5.1 brings built-in support for dual SIMs (previously something OEMs had to add) and HD Voice support.
Android 5.1 is one of the smaller minor version Android updates, down there with versions 4.2 and 4.3. But it brings a few nice changes and thankfully seems to solve many of the Nexus 6 performance problems.
The Raspberry Pi Foundation make it pretty clear that Raspbian is the recommended operating system for the Raspberry Pi series of computers. Most of the Foundation's documentation and support directs users to Raspbian. The downloads section of their website does list other operating system images. But there are many more images available, and one really piqued my curiosity; a Ubuntu 14.10 / Linaro 15.01 "developer" image. Unlike Raspbian, this image is compiled for ARMv7/armhf.
X.Org Server 1.17 has made it into Ubuntu 15.04.
While Mir will power the Ubuntu Touch devices, X.Org Server 1.17.1 will be used as the default desktop display server for this next Ubuntu Linux release due out in May. Xorg-server 1.17.1 was uploaded to the Ubuntu Vivid archive yesterday to replace the old 1.16 series.
Nvidia’s $199 STB version of Nvidia Shield runs Android TV on a Tegra X1, and boasts 4K video, 50 optimized games, and game streaming from a “Grid” service.
The 2015 set-top box version of the Nvidia Shield follows two earlier models, including 2013’s original handheld Shield game console, now called the Nvidia Shield Portable, which was based on the Nvidia Tegra 4 system-on-chip. Last year, the chip designer-cum-hardware developer released an Nvidia Shield Tablet built around a more powerful Tegra K1 SoC with Kepler graphics, and featuring new stylus and WiFi Direct gaming controller.
