Power of Unikernels and Linux Graphics

Filed under
  • Unikraft: Unleashing the Power of Unikernels

     The team at NEC Laboratories Europe spent quite a bit of time over the last few years developing unikernels – specialized virtual machine images targeting specific applications. This technology is fascinating to us because of its fantastic performance benefits: tiny memory footprints (hundreds of KBs or a few MBs), boot times compared to those of processes or throughput in the range of 10-40 Gb/s, among many other attributes. Specific metrics can be found in these articles: “My VM is Lighter (and Safer) than your Container,” “Unikernels Everywhere: The Case for Elastic CDNs,” and “ClickOS and the Art of Network Function Virtualization.”

    The potential of unikernels is great (as you can see from the work above), but there hasn’t been a massive adoption of unikernels. Why? Development time.  For example, developing Minipython, a MicroPython unikernel, took the better part of three months to put together and test. ClickOS, a unikernel for NFV, was the result of a couple of years of work.

  • First Batch Of AMDGPU Changes For Linux 4.16: DC Multi-Display Sync, Vega Tuning

    Alex Deucher of AMD sent in today their first batch of feature updates for Radeon/AMDGPU/TTM feature code for DRM-Next, which has already been queued, and will in turn land next year with the Linux 4.16 kernel.

  • Samsung Improving Cairo's OpenGL ES 3.x Support, May Eye Vulkan In Future

    Back in September there were developers from Samsung's Open-Source Group adding initial OpenGL ES 3.0 support to Cairo. The GLESv3 upbringing in Cairo is still ongoing and not yet fully vetted, but Bryce Harrington of Samsung OSG has now blogged about this effort.

    While there is the initial support for creating an OpenGL ES 3.0 context with Cairo, as Bryce explains in his new blog post, the work on GLES 3.0 for Cairo isn't complete. Additional code is still to be written to leverage new GLES3 functionality and they originally started writing this code for their Tizen platform.

Ubuntu: Logic Supply and Linux 4.15/Linux 4.16

  • Tiny Apollo Lake based mini-PCs run Ubuntu
    Logic Supply unveiled two 116 x 83 x 34mm mini-PCs built around a Celeron N3350: a CL200 with 3x USB ports and a CL210 that doubles memory to 2GB LPDDR4 and 32GB eMMC, and adds a second mini-DP and GbE port. Logic Supply announced its smallest mini-PCs to date with CL200 and CL210 models that measure just 116 x 83 x 34mm. The CL200 ships with Ubuntu 16.04 while the more advanced CL210 also offers Windows 10 IoT. Both of these “IoT Edge Device” mini-PCs tap Intel’s dual-core, 1.1GHz Celeron N3350 with 6W TDP from the Apollo Lake generation, and support digital media, data acquisition, automation, and network gateway applications.
  • Ubuntu 18.04 LTS Continues Prepping With The Linux 4.15 Kernel
    There were various calls by independent end-users voicing their two cents that Ubuntu 18.04 "Bionic Beaver" should ship with Linux 4.16 instead of Linux 4.15, but that isn't going to happen. In several different places the past few weeks I've seen various remarks made of how "Ubuntu 18.04 should ship with Linux 4.16" on the basis of either better Spectre/Meltdown support, Linux 4.16 will be out in time and neither 4.15 or 4.16 are even LTS releases, better hardware support, or users simply wanting all the goodies in Linux 4.16. But that's simply foolish given Ubuntu 18.04 is being a Long Term Support release and how close the timing ends up being as is.
  • Kernel Team summary: March 21, 2018
    On the road to 18.04 we have a 4.15 based kernel in the Bionic repository.

Graphics: mesa 17.3.7, mesa 18.0.0-rc5, VGA_Switcheroo and More

  • mesa 17.3.7
    Mesa 17.3.7 is now available.
  • Mesa 17.3.7 Released With A Bunch Of Fixes
    While Mesa 18.0 should finally be out on Friday as the major quarterly update to the Mesa 3D drivers, Mesa 17.3.7 is out today and it's a rather big update for being just another point release to last month's 17.3 series. Last week marked the release candidate of Mesa 17.3.7 with 50+ changes and then on Monday came a second release candidate given all the extra patches.
  • mesa 18.0.0-rc5
    The fifth and final release candidate for Mesa 18.0.0 is now available.
  • Mesa 18.0-RC5 Released, Mesa 18.0 Should Finally Be Out On Friday
    Nearly one and a half months since Mesa 18.0-RC4 and nearly one month since last seeing any Git activity on the "18.0" Mesa Git branch, it's finally been updated today with the availability of Mesa 18.0-RC5. Mesa release manager Emil Velikov announced this long-awaited release candidate today. He says this is the fifth and final release candidate. Given the month plus since the last RC, there are many fixes/changes in this release: In fact, more than 80 changes in total for Mesa 18.0-RC5.
  • Improved VGA_Switcheroo Going Into Linux 4.17
    Google's Sean Paul has sent in the final drm-misc-next pull request to DRM-Next of new feature material for the upcoming Linux 4.17 kernel cycle. Most notable with this final drm-misc-next update is the recent VGA_Switcheroo improvements by Lukas Wunner. This is the device link
  • AMD Posts Open-Source Driver Patches For Vega 12
    It's been a while since last hearing anything about the rumored "Vega 12" GPU but coming out this morning are a set of 42 patches providing support for this unreleased GPU within the mainline Linux kernel. Alex Deucher of AMD's Linux driver team sent out the 42 patches this morning providing initial support for Vega 12 within the AMDGPU DRM kernel driver.

    DXVK, the exciting project implementing the Direct3D 11 API over Vulkan for Wine gamers, now has an on-disk shader cache.
  • Freedreno's MSM DRM Driver Continues Prepping For Adreno 600 Series Support
    Rob Clark has submitted the MSM DRM driver changes to DRM-Next for the Linux 4.17 kernel for benefiting Qualcomm SoC owners. Changes this cycle for the open-source MSM DRM driver include DSI updates, fixing some race conditions, DebugFS enhancements, MDP5 fixes, and refactoring/prep work for the Adreno 600 series support.
  • NVIDIA's Jetson TK1 Is Being EOL'ed Next Month
    Easily one of our favorite ARM single-board computers ever, the Jetson TK1 from NVIDIA, will be facing retirement next month. A Phoronix reader has tipped us off that NVIDIA has sent out their EOL notice that shipments of the Jetson TK1 developer kits will be ending by the end of April. Following that, it will just live on until distributors run out of their inventory.

Slax Linux Distribution Begins Planning For Its First 2018 Release

Arriving last Christmas was a rejuvenated release of Slax, the long-running, lightweight Linux distribution with its development restarting last year and having shifted from being a Slackware derivative to Debian and moving from KDE to Fluxbox+Compton. Those involved are working on a new Slax release for 2018. Slax lead developer Tomas Matejicek has announced work is underway on the next version of this modern Slax OS with Debian+Fluxbox.
