Out now is the SteamOS 2.80 Brewmaster Beta update for those using Valve's Linux distribution for gaming. SteamOS 2.80 most notably brings the AMDGPU-PRO driver...
The Linux Kernel's PWM (Pulse Width Modulation) interface now has an atomic API for those writing drivers for fans, LEDs, vibrators, and other supported devices...
The Linux kernel has been working on many Year 2038 fixes for a while now but the work is not over. Another pull request was sent in for the Linux 4.7 kernel in trying to prepare the VFS layer with Y2038 fixes...
It was just last week that Intel crossed OpenGL 4.2 in Mesa and earlier today the needed Intel OpenGL 4.3 patches landed while tonight there are patches pending for the OpenGL 4.4 changes for Intel's open-source Linux graphics driver...
Yesterday marked the public availability of Dota 2 with a Vulkan renderer after Valve had been showing it off for months. This is the second commercial Linux game (after The Talos Principle) to sport a Vulkan renderer and thus we were quite excited to see how this Dota 2 Vulkan DLC is performing for both NVIDIA GeForce and AMD Radeon graphics cards. Here are our initial Dota 2 benchmarks with Vulkan as well as OpenGL for reference when using the latest Linux graphics drivers on Ubuntu.
While the NVIDIA 367 Linux driver series is where the very latest proprietary driver features from the green team can be found, if you have been sticking to the NVIDIA 361 driver series since it's the current long-lived branch, a new release is now available...
Following last week's AMDGPU-PRO 16.20.3 "Beta 2" driver release of AMD's new hybrid driver stack for Linux that makes use of the AMDGPU open-source kernel DRM driver with the closed-source OpenGL driver derived from Catalyst / Radeon Software, I set out to do a fresh open vs. closed-source driver comparison. For the Radeon R9 285, R9 290, and R9 Fury, I compared the performance of this new AMDGPU-PRO driver against Mesa 11.3-devel Git and Linux 4.6 for the latest open-source driver stack.
A few days ago when delivering benchmarks of the new CPUFreq "Schedutil" governor in Linux 4.7 the P-State comparison results on this Git kernel looked particularly terrible. I've since done some P-State tests on the same system using the Linux 4.5 and 4.6 kernels that further point towards a regression having taken place...
Last week's release of systemd 230 ended up shipping with a change that made it more easy for processes running as a user to snoop on frame-buffer devices. That change has already been reverted for the next systemd update...
Coming up in a short while I have some fresh AMDGPU-PRO BETA 2 (the fresh -PRO "hybrid" driver release) for OpenGL graphics performance while here are some quick OpenCL compute metrics...
Yesterday marked the official start of the projects for this year's Google Summer of Code and the summer round of the Outreachy (formerly the Outreach Program for Women) projects...
The recent release of QEMU 2.6 has support for allowing guests to do bursts of I/O for a configurable amount of time, whereby the I/O level exceeds the normally allowed limits...
Another one of the interesting pull requests this week for the Linux 4.7 merge window is the addition of ZAC (Zone ATA Command) support for Singled Magnetic Recording (SMR) devices...
Released on Saturday was the new AMDGPU-PRO Linux beta driver release for the AMD GCN 1.2 graphics cards. Given the time that's passed since the first beta of this "hybrid" open/closed driver stack, I've been running some fresh benchmarks...
The DRM subsystem updates have been submitted for the Linux 4.7 kernel. This is a big pull with more than 80,000 lines of new code for the mainline kernel!..
A change made in the recent release of systemd 230 makes it easy for rogue user processes to be able to spy on your desktop, assuming a few conditions are met...
This past week I showed how Intel Broadwell graphics are much faster with Mesa 11.3 but this new Mesa version doesn't do much for Haswell. Similar to Broadwell, Mesa 11.3 is a big win if you are on Intel's latest-generation Skylake hardware.
New to the upcoming Mesa release is the OpenSWR software rasterizer developed by Intel and geared for faster performance, at least for the workloads of most interest to the Intel engineers working on this driver...
With the in-development Linux 4.7 kernel there is a new CPUFreq governor that leverages the kernel's scheduler utilization data in an attempt to make better decisions about adjusting the CPU's frequency / performance state. Here are some benchmarks of that new CPUFreq governor, Schedutil, compared to the other CPUFreq governors as well as the Intel P-State CPU frequency scaling driver.
We've been waiting to see Vulkan on Mir after the developers working on this display server for Ubuntu missed their original Ubuntu 16.04 target but the latest chatter indicates we might be seeing the support materialize soon...
For Broadwell hardware and newer, this week marked the milestone of the Intel Mesa driver exposing OpenGL 4.2 support. However, they are only one extension away from OpenGL 4.3 compliance for the newer Intel graphics hardware and a new version of that patch-set was just posted...
