No Surprise But Intel Linux Developers Are Working Towards Adaptive-Sync Support

Thursday 14th of February 2019 08:39:18 AM
Back during the Intel Architecture Day event in December, Intel confirmed that finally with Icelake "Gen 11" graphics there is Adaptive-Sync support after talking about it for several years. While they didn't explicitly mention Linux support, they've been largely spot on for years with supporting new display features on Linux and this should be the case as well with Adaptive-Sync and their next-generation graphics...

Microsoft Developer: You Still Should Have Anti-Virus With Windows Subsystem For Linux

Thursday 14th of February 2019 05:27:12 AM
While disabling Windows Defender or other anti-virus programs may partially help offset the performance losses imposed by running Windows Subsystem for Linux, a.k.a. "Bash for Windows" or Ubuntu and other distributions running natively atop Windows 10 and now Windows Server 2019, it's not the root cause of the I/O performance bottleneck and is not a recommended course of action...

AMD_DEBUG Can Now Be Used In Place Of R600_DEBUG For RadeonSI Options

Wednesday 13th of February 2019 07:08:54 AM
When setting various debug options for the RadeonSI Gallium3D driver -- like enabling its NIR back-end among many other options -- that has traditionally been done through the R600_DEBUG= environment variable. But that variable name makes little sense these days since RadeonSI doesn't even support the now-vintage R600 GPUs. Thankfully, AMD_DEBUG= is now a supported alternative...

GCC 8/9 vs. LLVM Clang 7/8 Compiler Performance On AArch64

Tuesday 12th of February 2019 08:35:00 PM
With Clang 8.0 due out by month's end and GCC 9 due for release not long after that point, this week we've been running a number of GCC and Clang compiler benchmarks on Phoronix. At the start of the month was the large Linux x86_64 GCC vs. Clang compiler benchmarks on twelve different Intel/AMD systems while last week was also a look at the POWER9 compiler performance on the Raptor Talos II. In this article we are checking out these open-source compilers' performance on 64-bit ARM (AArch64) using an Ampere eMAG 32-core server.

Slovak advocates want parliament to push for open source

Slovak proponents of the use of free and open source software are rallying for their country’s parliament to approve plans to share the source code of software solutions developed by and for public services. They are concerned that proprietary software vendors will lobby for changes to the eGovernment act, a strategic IT Government proposal that is to be discussed in parliament in March or April.

Intel Graphics: Discrete Graphics Cards and SVT-AV1

  • Intel Preps For Discrete Graphics Cards With Linux Patches
    Intel has confirmed that recent patches to its Linux graphics driver were related to its continued work on preparing the ecosystem for its new line of discrete graphics cards. Phoronix reported that Intel released 42 such patches with more than 4,000 lines of code between them on February 14. The main purpose of the patches was to introduce the concept of memory regions in "preparation for upcoming devices with device local memory." (Such as, you know, discrete graphics cards.) [...] Still, any information about Intel's graphics plans is welcome. Right now the graphics market is dominated by AMD and Nvidia, and as we noted in December, Intel is probably the only company that even has a possibility of successfully introducing a new discrete graphics architecture. Why not enjoy the occasional glimpse behind the curtain as that architecture's being built?
  • SVT-VP9 Is Intel's Latest Open-Source Video Encoder Yielding High Performance VP9
    At the start of the month Intel open-sourced SVT-AV1 aiming for high-performance AV1 video encoding on CPUs. That complemented their existing SVT-HEVC encoder for H.265 content and already SVT-AV1 has been seeing nice performance improvements. Intel now has released SVT-VP9 as a speedy open-source VP9 video encoder. Uploaded on Friday was the initial public open-source commit of SVT-VP9, the Intel Scalable Video Technology VP9 encoder. With this encoder they are focusing on being able to provide real-time encoding of up to two 4Kp60 streams on an Intel Xeon Gold 6140 processor. SVT-VP9 is under a BSD-style license and currently runs on Windows and Linux.

How I got my job in Linux: from Newbie to Pro

I was peeved, because I’d spent my own money on building a computer and buying Microsoft Windows to put on it. Money that I really needed to pay the rent and put food in my belly. I also felt sorry for all the people that I’d end up re-installing Windows on their PC to fix their problem. I knew that most of them would probably be back in the store six or so months later with the same complaint. Almost by accident, I found Linux. I was in the magazine section of the PC shop I worked in one day in late 1999. I saw a magazine called ‘Linux Answers’. On the cover was a copy of Red Hat Linux 6.0. Before long, I had done the unthinkable: I had deleted Windows in a rage of fury because it had completely crashed and wouldn’t start up. All of my MP3s, photos and documents, all but gone save for a few backups on CDs I had lying around. Back in those days I had no idea that I would have been able to salvage those files with Linux; I just blithely reformatted my hard disk and went cold-turkey, believing everything that the magazine said, I forced myself into the abyss of the unknown! These were exciting times! I remember the blue text-mode installer, the glare of the many lines of text flying by when the machine started up for the first time. It looked really un-user friendly. Eventually, the screen flipped into what I’d later know to be called ‘runlevel 5’ and I could see a graphical login screen. Little did I know it, but that flashing cursor was the beginning to a whole new world of computing for me. Read more

Linux 5.0-rc7

A nice and calm week, with statistics looking normal. Just under half drivers (gpu, networking, input, md, block, sound, ...), with the rest being architecture fixes (arm64, arm, x86, kvm), networking and misc (filesystem etc). Nothing particularly odd stands out, and everything is pretty small. Just the way I like it. Shortlog appended, Linus Read more
