Radeon Linux Benchmarks: Catalyst 15.3 Beta vs. Linux 4.0 + Mesa 10.6-devel

Filed under
Graphics/Benchmarks

Before ending out March, here's some new OpenGL Linux benchmarks comparing the closed-source Catalyst 15.3 Beta driver against the Linux 4.0 development kernel with Mesa 10.6 Git for the freshest open-source graphics driver code.

Mesa's Android Support Is Currently In Bad Shape

Filed under
Graphics/Benchmarks

While Mesa is talked about as being able to be built for Google's Android operating system to run these open-source graphics drivers on Android devices with OpenGL ES support, in reality there's a lot left to be desired.

Over the years there's been a handful of developers working on Android Mesa support to let the popular open-source graphics drivers run over there -- from the Intel driver now that they're using HD Graphics within their low-power SoCs (rather than PowerVR), AMD has made a few steps toward Android netbook/laptop devices with Radeon graphics, and we're starting to see Gallium3D drivers for Qualcomm Adreno (Freedreno) and the Raspberry Pi (VC4) where there's interest from Android users. This year as part of Google Summer of Code we also might see a student focused on Freedreno Android support.

Graphics/Benchmarks
Linux

Those with a bit of humor will love the demo NVIDIA recently used for showing off their Nouveau-based open-source graphics driver stack on the Tegra K1 SoC.

Last month at FOSDEM was a presentation on the Nouveau Tegra K1 driver stack by Alexandre Courbot of NVIDIA. In there NVIDIA talked about their great experience working on this open-source driver and engagement with the Nouveau community, which will continue for future Tegra SoCs. That aforelinked article covered all of the important details of that presentation.

Linux

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.

A Look At BCache vs. LVM Cache For HDD+SSD Linux Systems

Filed under
Graphics/Benchmarks
Linux

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.

Linux Performance Analysis: New Tools and Old Secrets

Filed under
Graphics/Benchmarks
Linux

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.

A look at Android 5.1: speed, security, tweaks

Filed under
Android
Graphics/Benchmarks

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.

Tiny, stackable, Linux-based IoT module hits Kickstarter

On Kickstarter, Onion launched a tiny, Linux-based “Omega” IoT module, along with a dock, stackable expansion modules, a cloud service, and web app tools. Onion’s Omega joins a growing number of single board computers and computer-on-modules for Internet of Things applications that have tapped Qualcomm’s MIPS-based, WiFi-enabled Atheros AR9331 system-on-chip. For a pledge of $25, Onion’s Kickstarter campaign offers the Omega computer-on-module combined with a “dock” that turns it into an sandwich-style single board computer. Read more

Development activity in LibreOffice and OpenOffice

The LibreOffice project was announced with great fanfare in September 2010. Nearly one year later, the OpenOffice.org project (from which LibreOffice was forked) was cut loose from Oracle and found a new home as an Apache project. It is fair to say that the rivalry between the two projects in the time since then has been strong. Predictions that one project or the other would fail have not been borne out, but that does not mean that the two projects are equally successful. A look at the two projects' development communities reveals some interesting differences. Read more
