Most often when talking of new OpenGL 4 extensions in Mesa it tends to be regarding the Intel Mesa driver given they're the company investing the most into the Linux graphics stack, followed by the Radeon and Noveau drivers. However, this week in Mesa is some love to the fallback/debugging software rasterizers...

With Mesa 10.6 due to be released in early June, our usual performance comparisons of this new Mesa 3D version will come. To get our latest round of Mesa open-source graphics driver benchmarking kicked off, here are benchmarks of Intel's Iris Graphics when comparing Mesa 10.5 and 10.6 Git atop Ubuntu 15.04.
Just this morning the major VENOM security vulnerability was made public while a few hours later, a kernel developer has gone public with four "remote packet of death" vulnerabilities affecting a mainline Linux kernel WLAN driver...
While writing this morning about Intel Cherryview support being added to Beignet, I also noticed Intel developers have been quietly fleshing out OpenCL 2.0 support for Linux...
Fedora 22 is now under its final freeze with planned availability before month's end. I've been running Fedora 22 on various development systems and in the benchmarking farm at Phoronix to great success.
Intel's been working on open-source Linux support for Cherryview for more than one year while finally one of the last pieces of the hardware enablement puzzle has landed: OpenCL support for Cherryview...
Qt 5.5 has been running behind schedule for some time while now The Qt Company is trying to get it back on track and to officially ship Qt 5.5 by the end of next month...
DNF 1.0 was released this week ahead of the Fedora 22 debut later this month where it will replace Yum by default as the package manager. In my testing of DNF on Fedora 22 and earlier releases, it's worked out quite well, but there's one issue that still nags me about Dandified Yum...
I've found out from various people in the know that AMD has assembled a "tiger team" to tackle outstanding Catalyst driver issues. This tiger team isn't Linux specific, but Linux driver issues will be fully evaluated and tackled by this new group of driver specialists...
Foresight Linux was a great distribution back in the day for showcasing the latest GNOME components, but after a decade of work, the project is shutting down...
This summer on Phoronix we'll be welcoming Eric Griffith to the team, a student from the California University of Pennsylvania. Eric will be an intern at Phoronix via his journalism program at the university. Eric has already written about his new laptop with Linux and he'll be writing many more Linux/open-source articles on Phoronix over the next few months. Please join me in welcoming him to his summer internship. He's prepared a few remarks to get started...
One of the latest commits to the xorg-server that's seen relatively few commits this development cycle is support for smooth scrolling with XWayland...
The day is coming where DNF is replacing Yum as the default package manager on Fedora Linux. DNF 1.0 was just released today to mark the point of stability and it being ready to take over Yum's responsibilities with the upcoming Fedora 22 release...
With the transformation of a basement into a large Linux server room (50+ computers), I previously wrote about the sub-$50 4U ATX server case and 2U micro-ATX server case commonly used for housing the many Linux systems in this lab running continuous performance benchmarks. For the EATX systems, here's the server chassis I've gone with and experienced great results out of this EATX/SSI rackmount chassis that can be found online for as little as $80 USD.
Back in 2013 the Jailhouse Hypervisor was announced as a partitioning hypervisor that's lighter-weight than KVM. Last year saw the release of Jailhouse 0.1 and finally coming out today is the next update: Jailhouse 0.5...
While Linux distributions like Fedora and Mageia have adopted predictable/persistent network interface names, Ubuntu has not. However, that is looking to change and it might also be the case for upstream Debian...
Intel's Open-Source Technology Center continues to hire new developers for working on their Linux graphics stack. Back in 2013, Intel had 20~30 full-time Linux graphics driver developers and since then that number has only risen...

In our routine compiler benchmarks looking at LLVM/Clang vs. GCC, the performance has certainly gotten tight over the years but one of the areas where there's still been a large difference are in workloads that can make use of OpenMP for multi-threading. Fortunately, Clang has finally finished up its OpenMP 3.1 support...
A Red Hat developer mentioned to us at Phoronix that they're seeing "drastically improved battery life" in some cases with the Linux 4.1 kernel to the extent that it's up to 2~4 hours of extra battery life with the kernel upgrade to Git. I've since started some fresh Linux laptop battery tests.
Linus Torvalds just announced the release of the Linux 4.1-rc3 kernel, which he's called the "Mother's Day Sunday release" for those celebrating this holiday...
This is a guest post by Tom Li, a Phoronix reader wishing to share his views on the increasing problems of free/open-source software public mailing lists being flooded with spam and other garbage. There are some extreme situations where there can be "flooding attacks" of list subscribers receiving thousands of mailing list messages per day from attackers. Tom is hoping the open-source community can come up with better solutions to fend off this problem...
