Recently there were a number of requests about testing the latest state of Liquorix, the self-prcolaimed "better distro kernel" that is an optimized version of the Linux kernel with extra patches that makes it optimal for desktop, multimedia, and gaming workloads. Here's some fresh Liquorix vs. mainline Linux kernel performance benchmarks.
Wayland has been ported to DragonFlyBSD along with its Weston compositor!
In the past we've seen some minor experiments by BSD developers with Wayland/Weston, but for the most part all of the BSDs are still focused on X.Org Server support -- need I remind Phoronix readers that DRM/KMS support is in varying stages across the BSD distributions too as one of the support stepping stones. Just a few days ago I ran into the DragonFly Radeon kernel module failing to properly mode-set with a several year old (pre-GCN) graphics card while meanwhile FreeBSD's Radeon KMS port worked. It's still rather a mine field when it comes to open-source graphics acceleration and support on the BSDs while slowly but surely their catching up with the kernel code.
Alexandre Courbot, a developer at NVIDIA who has been working on the Tegra open-source graphics support a lot for Nouveau, presented last week at LinuxCon Europe 2015.
Thanks to the work by Courbot and others at NVIDIA, the Tegra K1 with its Kepler GPU has mainline Nouveau graphics support while the open-source graphics enablement for the Tegra X1 with Maxwell GPU continues to be upstreamed.
It's been a while since last running any BSD vs. Linux benchmarks, so I've started some fresh comparisons using the latest releases of various BSDs and Linux distributions. First up, as for what's completed so far, is using the FreeBSD-based PC-BSD 10.2 compared to Ubuntu 15.04 stable and the latest development release of Ubuntu 15.10.
With Ubuntu 15.10 set to be released later this month, I've started preparing for a variety of Linux performance comparisons involving the Wily Werewolf. This morning I ran some Ubuntu 15.04 vs. 15.10 benchmarks on one of my frequent test beds and it's revealed a few significant changes in some of the benchmarks.
AMD sent in a batch of fixes for the AMDGPU kernel driver today for Linux 4.3. One notable change with this AMDGPU DRM driver update is that it marks the Iceland/Topaz graphics processor support as experimental so it's no longer enabled by default until the support has been better vetted.
Since this summer we've known that Canonical developers have been looking at Vulkan in regards to supporting this forthcoming graphics API by Unity 8 and Mir. Since then we've seen work done in Mir to support renderers other than OpenGL with this Ubuntu display server. As another sign of working towards Vulkan, more of Mir's OpenGL code continues to be re-factored.
Given the recent releases of FreeBSD 10.2 and NetBSD 7.0, plus the H2'2015 Linux distribution updates rolling around, I've just started work on a new BSD vs. Linux operating system performance comparison.
First up are the BSD distributions for testing... The test system being used for this comparison is an Intel Xeon E5-2687W v3 Haswell-E plus AMD FirePro system. Given the new release of NetBSD 7.0, I decided to try that out first.
