  • Vulkan 1.0.56 Brings One New Extension, Fixes

    Khronos' SIGGRAPH announcements are coming up in just over one week but today we have the Vulkan 1.0.56 release.

  • Nouveau Gets Thermal Throttling, One Step Closer For GTX 900 Re-Clocking

    Nouveau re-clocking/power expert Karol Herbst has published a set of patches today implementing thermal throttling support for this open-source NVIDIA DRM driver.

  • Mesa 17.2 Merge Window Extended To Sunday, RADV Shared Semaphores Lands

    The merging fun for Mesa 17.2 will continue through the weekend.

    Mesa release manager Emil Velikov has shared rather than going into feature freeze today, he's planning to extend it by a few days. In particular, he's planning to branch now by Sunday evening to allow for some remaining patches to be merged.

  • A small Update

    I planned on writing about the Present extension this week, but I’ll postpone this since I’m currently strongly absorbed into finding the last rough edges of a first patch I can show off. I then hope to get some feedback on this from other developers in the xorg-devel mailing list.

    Another reason is that I stalled my work on the Present extension for now and try to get first my Xwayland code working. My mentor Daniel recommended that to me since the approach I pursued in my work on Present might be more difficult than I first assessed. At least it is something similar to what other way more experienced developers than myself tried in the past and weren’t able to do according to Daniel. My idea was to make Present flip per CRTC only, but this would clash with Pixmaps being linked to the whole screen only. There are no Pixmaps only for CRTCs in X.

  • Revised DRI3 v1.1 Modifiers Support For Mesa

    Daniel Stone of Collabora has published a new set of 14 patches implementing DRI3 v1.1's modifiers support inside Mesa with support for EGL X11 and Vulkan X11/Wayland.

Linux

Similar to our past disk encryption benchmarks, a clean install of Fedora Linux (26, with Linux 4.11) was done without any encryption and then again when opting for the full-disk encryption setup via the Anaconda installer. EXT4 was the file-system in use with its default mount options and no other changes were made between the installations or during the benchmarking process.

  • Linus Torvalds: Gadget reviewer

    If you know anything about Linus Torvalds, you know he's the mastermind and overlord of Linux. If you know him at all well, you know he's also an enthusiastic scuba diver and author of SubSurface, a do-it-all dive log program. And, if you know him really well, you'd know, like many other developers, he loves gadgets. Now, he's starting his own gadget review site on Google+: Working Gadgets.

  • Intel Mesa Driver Lands Support For OpenGL ARB_shader_ballot
  • Linux 4.11 vs. 4.12 vs. 4.13-rc1 Intel Kabylake Graphics Tests

    Besides testing the Radeon/AMDGPU work in Linux 4.13, here are some fresh benchmarks of Intel Kabylake GT 2 / HD Graphics 630 from this new in-development kernel.

    The Intel kernel graphics driver changes for 4.13 are outlined in our Linux 4.13 feature overview. Using the Intel Core i7 7700K I did some comparison tests of Linux 4.13-rc1 compared to 4.12.0 and 4.11.0 stable.

AMDGPU vs. Radeon DRM On Linux 4.13 For AMD GCN 1.0/1.1 GPUs

Filed under
Graphics/Benchmarks

With the Linux 4.13 kernel currently under development there are new module parameters that can make it easier switching from the Radeon DRM default on GCN 1.0 and GCN 1.1 GPUs to instead using the newer AMDGPU DRM driver, but Radeon remains the default. Here's my test experiences and benchmark results of AMDGPU vs. Radeon for GCN 1.0/1.1 GPUs.

  • Intel Stages More Code In DRM-Next For Linux 4.14

    Intel's Daniel Vetter has sent in a second batch of code updates of new feature work to be staged in DRM-Next for the eventual Linux 4.14 kernel cycle.

    For end-users this latest intel-drm-next code isn't too exciting, but it does have more fixes around support for Intel's next-generation Cannonlake hardware. Cannonlake is still months away from succeeding Kabylake, but should be exciting on the graphics side as it's introducing "Gen 10" graphics. Cannonlake details are still light, but stay tuned to Phoronix to learn more over the months ahead. The Intel Linux developers have been bringing up this next-gen hardware for months and with Linux 4.14 the support is being further readied.

  • VC5 Driver Development Continues, Raspbian Performance Still Being Tuned

    Earlier this month the VC5 open-source driver was announced as a new driver for Broadcom's next-generation graphics processor. This has already led to speculation this much more powerful GPU will be found in future Raspberry Pi hardware. Work on this driver has continued while not forgetting about the VC4 driver for current-gen Raspberry Pi devices.

  • Intel Windows OpenGL Driver Finally Has v4.5, Catching Up To Mesa

    While Intel's Mesa-based open-source OpenGL Linux driver has been officially conformant since early 2017 and has enabled OpenGL 4.5 since last October, the Intel Windows OpenGL driver is finally catching up.

  • GCC vs. Clang Compilers On The Intel Core i9 With Clear Linux

    For those curious about the GCC versus LLVM Clang compilers with Intel's new Core i9 7900X, earlier this month I had ran some compiler benchmarks on this high-end processor.

    I simply forgot to post these GCC vs. Clang i9-7900X benchmark results earlier, but here they are for those interested. The tests were done with the performance-oriented Clear Linux distribution.

  • New Features Coming For Glibc 2.26

    Given our recent articles of Glibc enabling a per-thread cache for malloc and Fedora 27 will use glibc 2.26, you may be curious about some of the other features coming to this next version of the GNU C Library.

Red Hat: Patent 'Promise', Proprietary 'Gifts', Imminent Results, Fedora 27 Delays

  • Red Hat pledges patent protection for 99 per cent of FOSS-ware [Ed: And when Red Hat gets taken over (like Sun and Oracle) this promise will be worthless]
    Red Hat says it has amassed over 2,000 patents and won't enforce them if the technologies they describe are used in properly-licensed open source software. The company's made more or less the same offer since the year 2002, when it first made a “Patent Promise” in order to “to discourage patent aggression in free and open source software.” In 2002 the company didn't own many patents and claimed its non-enforcement promise covered per cent of open source software. The Promise was revised in order to reflect the company's growing patent trove and to spruce up the language it uses to make it more relevant. The revised promise “applies to all software meeting the free software or open source definitions of the Free Software Foundation (FSF) or the Open Source Initiative (OSI)”. That verbiage translates into any software licensed on terms the OSI approves on this list, or which meet the Initiative’s definition of open source offered here. Licenses listed by the Free Software Foundation as a free software license at https://www.gnu.org/licenses/license-list.html#SoftwareLicenses also come under the Promise's purview, as do those here as of the date this edition of Our Promise is published.
  • Red Hat Open Source Day rewards with proprietary hardware. For the fourth time

  • Fedora 27 Beta Hit By A Second Delay
    Last week it was decided to delay the Fedora 27 beta due to bugs while this week they've been forced to delay the release a second time. The first beta delay wasn't too bad as the F27 schedule already had a built-in "rain date", in acknowledging Fedora's frequent release delays. But today a second unplanned delay is pushing back F27 Beta by at least one more week. This will now also push back the Fedora 27 final release by at least one week.

Security: Apple's Betrayal, Intel ME Back Doors Backfire, and Optionsbleed

  • iOS 11 Muddies WiFi and Bluetooth Controls
    Turning WiFi and Bluetooth off is often viewed as a good security practice. Apple did not rationalize these changes in behavior.
  • How To Hack A Turned-Off Computer, Or Running Unsigned Code In Intel Management Engine
    Intel Management Engine is a proprietary technology that consists of a microcontroller integrated into the Platform Controller Hub (PCH) microchip with a set of built-in peripherals. The PCH carries almost all communication between the processor and external devices; therefore Intel ME has access to almost all data on the computer, and the ability to execute third-party code allows compromising the platform completely. Researchers have been long interested in such "God mode" capabilities, but recently we have seen a surge of interest in Intel ME. One of the reasons is the transition of this subsystem to a new hardware (x86) and software (modified MINIX as an operating system) architecture. The x86 platform allows researchers to bring to bear all the power of binary code analysis tools.
  • Optionsbleed: Don’t get your panties in a wad
    To be honest, this isn’t the first security concern you’ve run in to, and it isn’t the first security issue you’re vulnerable to, that will remain exploitable for quite some time, until after someone you rely on fixed the issue for you, meanwhile compromising your customers. [...] Is it a small part of the SSL public key? A small part of the web request response? A chunk of the path to the index.php? Or is it a chunk of the database password used? Nobody knows until you get enough data to analyse the results of all data. If you can’t appreciate the maths behind analysing multiple readings of 8 arbitrary bytes, choose another career. Not that I know what to do and how to do it, by the way.

OSS: Puppet Acquires Distelli, Mozilla Adds Tracking Protection, Fake List of Open Source Companies, and Open Source Summit

  • Puppet Acquires Distelli, Boosting Its Cloud Automation Offerings
    Puppet, the open source company that markets cloud-native software management tools, has acquired startup Distelli. Based in Seattle, Distelli offers a software as a service platform used by developers to build, test, and deploy code written in any language to any server, including cloud platforms. This is an obvious good match, as both platforms enable developers to manage infrastructure and applications across the entire software delivery process to make app development quicker. "Today, a company's success is predicated on how quickly and successfully it can deliver new experiences to customers through software," Puppet's CEO, Sanjay Mirchandani, said in a statement. "Automation makes world-class application delivery straightforward for every enterprise, not just for companies born in the cloud. Together with Distelli, we are bringing a comprehensive solution for orchestrating and automating the entire software delivery lifecycle, from infrastructure, all the way up through containers."
