  • VLC Now Has Zero-Copy Support For GStreamer Video Decoding

    It was just last week we got to write about VLC 3.0 features and early planning for VLC 4.0 while this weekend in Git there is another feature to add to the list.

    The latest VLC development code now supports zero-copy GStreamer video decoding. With the zero-copy comes increased efficiency and performance.

  • NVIDIA GeForce GT 710: Trying NVIDIA's Newest Sub-$50 GPU On Linux

    The GeForce GT 710 is a cut-down version of the Kepler GK208, the already low-end core used by the lines of the GT 720 and GT 730 graphics cards as well as the mobile GT 720M/730M/735M/740M graphics processors. This really isn't a graphics card for gamers or anyone needing any serious GPU performance but rather as an upgrade for an entry-level system, someone just wanting to upgrade from their integrated graphics, and other minimally-demanding use-cases.

  • Mesa 11.2 Is Set For Branching In Just Two Weeks, Release In Just Over One Month

    The race is on to see if any of the Mesa/Gallium3D hardware drivers (or core Mesa itself) will reach any new version levels for Mesa 11.2.

  • AMD Is Looking At A Interoperability Interface For OpenCL Outside Of Mesa

    AMD's Marek Olšák has begun exploring an interoperability interface for OpenGL within Mesa and having a non-Mesa OpenCL implementation (not Clover OpenCL Gallium3D).

    Likely as part of their HSA work and hopefully in providing better AMD open-source OpenCL support aside from the (currently limited) Gallium3D Clover state tracker, Marek is trying to hash out an interface for allowing interoperability with "MesaGL" and a non-Mesa OpenCL driver.

Ubuntu

As I'm in the process of retiring an old AMD Opteron dual-socket system, prior to decommissioning it, I figured it would be fun to go back and re-benchmark all of the Ubuntu LTS releases going all the way back to the legendary 6.06 Dapper Drake release. So here are some fresh benchmarks of this AMD Shanghai system with eight cores and 16GB of RAM when re-benchmarking the releases from Ubuntu 6.06 through the latest Ubuntu 16.04 LTS development state.

Linux

While Next Thing Co is still working to fulfill orders on the C.H.I.P. $9 computer over the next several months, I noticed that some benchmarks of this cheap Raspberry Pi competitor have begun appearing on OpenBenchmarking.org via the Phoronix Test Suite. Here are some of those benchmark results for this ARB single-board computer.

For those that don't recall this crowd-funding campaign, the C.H.I.P. is a $9 computer with a 1GHz ARM single-core processor, 512MB of RAM, and 4GB of storage. The C.H.I.P. is cheap. I hadn't paid much attention to the campaign since I'm more into high-performance ARM chips than whatever the cheapest ARM SBC is around. However, these early benchmark results on OpenBenchmarking.org are rather interesting.

  • The Open-Source Vivante DRM Driver Has A Promising Future

    With the upcoming Linux 4.5 kernel, one of the new hardware drivers is the long-in-development Etnaviv DRM driver for providing reverse-engineered, open-source support to Vivante GPUs found in use by multiple SoC vendors.

  • leaking buffers in wayland

    So in my last blog post I mentioned Matthias was getting SIGBUS when using wayland for a while. You may remember that I guessed the problem was that his /tmp was filling up, and so I produced a patch to stop using /tmp and use memfd_create instead. This resolved the SIGBUS problem for him, but there was something gnawing at me: why was his /tmp filling up? I know gnome-terminal stores its unlimited scrollback buffer in an unlinked file in /tmp so that was one theory. I also have seen, in some cases firefox downloading files to /tmp. Neither explanation sat well with me. scrollback buffers don’t get that large very quickly and Matthias was seeing the problem several times a day. I also doubted he was downloading large files in firefox several times a day. Nonetheless, I shrugged, and moved on to other things…

  • R9 Fury Performance Gains With Linux 4.5-rc2? I'm Not So Lucky

    When reading this morning of "double or quadruple the framerates that I got with RC1" for an R9 Fury owned by a Phoronix reader, I immediately set out to run some R9 Fury benchmarks on Linux 4.5-rc2 compared to my 4.5-rc1 results last week and compared to Catalyst. I also did the same for an R9 285 Tonga on AMDGPU as well for reference purposes.

  • AMDGPU ACP Support Called For Merging Still Into Linux 4.5

    While the Linux 4.5 kernel's merge window ended more than one week ago, it looks like the AMDGPU driver may get a late feature arrival: ACP support.

    ACP is the Audo Co-Processor support found in new AMD APUs/SoCs. AMD developers had been working on the support for several months while the audio and power management related ACP code landed during the Linux 4.5 merge window. With that code now mainlined, AMD's Alex Deucher is looking to land the ACP driver support into the AMDGPU DRM driver.

  • The Intel Mesa Driver Has Gotten Faster Since Switching To NIR

    Eduardo Lima of Igalia spoke this weekend at FOSDEM about the work done over the past year on switching the Mesa Intel i965 back-end to using the NIR intermediate representation.

    The presentation by this developer covered GLSL IR vs. NIR, the Intel shader pipeline, what NIR is all about, and more. NIR is the new Mesa intermediate representation that was initially designed by a high school student. Besides Intel's interest in NIR, Freedreno and VC4 Gallium3D drivers have also been actively interested in this IR.

  • Running The Radeon R7 260X With The Experimental AMDGPU Driver

    A few days back I showed the Radeon vs. AMDGPU vs. Catalyst kernel driver potential when testing on the R9 290 "Hawaii" graphics card that has experimental and disabled-by-default support for the new AMDGPU kernel driver primarily designed for AMD GCN 1.2 GPUs and newer. Those results were interesting and showed some areas where AMDGPU came out faster than Radeon, so I decided to run experimental tests on another GCN 1.1 Sea Islands GPU that can be made to work with this kernel driver.

  • AMDGPU In Linux 4.9 To Bring Virtual Display Support, Improved GPU Reset
    The first pull request has been submitted of new Radeon and AMDGPU DRM driver updates to be queued in DRM-Next for landing with the Linux 4.9 kernel. To look forward to Linux 4.9 even though Linux 4.8 is still weeks from being released is PowerPlay support for Iceland GPUs, improved GPU reset, UVD and VCE power-gating for Carrizo and Stoney, support for pre-initialized vRAM buffers, TTM clean-ups, virtual display support, and other low-level changes. Many bug fixes also present. The AMDGPU virtual display support is useful and we have been looking forward to it. GPU reset improvements are also welcome for better recovery when the GPU becomes hung. As is the case lately, most of these changes are focused around the newer AMDGPU DRM driver over the mature Radeon DRM code.

  • Wildfire ransomware code cracked: Victims can now unlock encrypted files for free
    Victims of the Wildfire ransomware can get their encrypted files back without paying hackers for the privilege, after the No More Ransom initiative released a free decryption tool. No More Ransom runs a web portal that provides keys for unlocking files encrypted by various strains of ransomware, including Shade, Coinvault, Rannoh, Rakhn and, most recently, Wildfire. Aimed at helping ransomware victims retrieve their data, No More Ransom is a collaborative project between Europol, the Dutch National Police, Intel Security, and Kaspersky Lab. Wildfire victims are served with a ransom note demanding payment of 1.5 Bitcoins -- the cryptocurrency favored by cybercriminals -- in exchange for unlocking the encrypted files. However, cybersecurity researchers from McAfee Labs, part of Intel Security, point out that the hackers behind Wildfire are open to negotiation, often accepting 0.5 Bitcoins as a payment. Most victims of the ransomware are located in the Netherlands and Belgium, with the malicious software spread through phishing emails aimed at Dutch speakers. The email claims to be from a transport company and suggests that the target has missed a parcel delivery -- encouraging them to fill in a form to rearrange delivery for another date. It's this form which drops Wildfire ransomware onto the victim's system and locks it down.
