For those wishing to test out the new Radeon code, Lauri's repositories for this work are this kernel repository and this Mesa repository. He said in an email this morning to me, "The code won't be changing beyond cleanups, there might be small edits to the thesis draft. As the main target was VRAM pressure, it will be pointless to test ioq3 games on 2 GB VRAM, for example - they will show no difference, as they fit completely into VRAM. You can use the radeon.vramlimit=256 kernel parameter to limit VRAM for testing different amounts. The kernel is fully backwards compatible with old mesa, so you should be able to compare just by changing mesa and the vram limit. I should note that there's a big ioq3 regression currently in mesa git, so if your comparison mesa is too far back, it could seem like it was caused by my work, when it's in reality in master too."
A second Git pull request has been made for the ACPI and power management code within the kernel for Linux 3.15.
This latest driver update arrives only a day after the previous Beta release, which caused quite a stir because it featured the option to overclock the video card. It may not seem like much but, in fact, this is actually great progress for the NVIDIA drivers.
UK microprocessor-design company ARM has decided to move to an open-source compiler for the latest release of its software development tools, moving away from its own technology.
The ThinkPad T530 laptop features support for a third-generation Intel Core processor, QM77 chipset, and Intel HD Graphics and NVIDIA Quadro NVS 5400M Graphics with Optimus Technology. The ThinkPad T530 support for Coreboot is based in large part on the Coreboot support for the ThinkPad X230 ultrabook that was added at the beginning of the year.
After much information being made public in March concerning AMD's AM1 platform that delivers socketed APUs for low-cost desktop systems, the first of these new socketed APUs are shipping today under the restored Athlon and Sempron branding. We've been fortunate enough to have one of the new Athlon AM1 APUs at Phoronix for a few days of testing.
As we've reported many times, the diminutive $25/$35 Linux computer dubbed Raspberry Pi has emerged as one of the biggest open source stories anywhere over the past couple of years. It's attracted all kinds of developers and tinkerers, is now running many different flavors of Linux, and there is even now a supercomputer consisting of many Pi devices lashed together with Lego pieces. In some of the more exotic new applications for Raspberry Pi, it's being used in music, robotics and security scenarios.
Changes for the F2FS file-system with Linux 3.15 include the introduction of support for large directories, performance improvements for some server workloads, new sysfs entries for better tuning F2FS configurations, and several bug-fixes.
Every month Valve publishes a comprehensive hardware and software survey that reflects what is being used to run the Steam client. It’s been pretty accurate until now, but a couple of months ago Valve made a few small modification and eliminated most of the inconsequential entries for various other distros.
