Graphics and Security Leftovers Published on Tux Machines (http://www.tuxmachines.org) Home > content > Graphics and Security Leftovers Graphics and Security Leftovers By Roy Schestowitz Created 20/08/2020 - 2:15am Submitted by Roy Schestowitz on Thursday 20th of August 2020 02:15:25 AM Filed under Graphics/Benchmarks [1] Security [2] Misc [3] TensorFlow Lite Now Supports Tapping OpenCL For Much Faster GPU Inference[4] TensorFlow Lite for AI inference on mobile devices now has support for making use of OpenCL on Android devices. In doing so, the TFLite performance presents around a 2x speed- up over the existing OpenGL back-end. To little surprise, the TensorFlow developers are finding their new OpenCL back-end for TFLite to be much faster than their OpenGL back-end for mobile inference. Thanks to better performance profiling abilities, native FP16 support, constant memory, and OpenCL being better designed for compute than OpenGL ES with compute shaders, the TFLite performance is much improved -- and especially so compared to doing inference on the mobile SoC CPU cores. GRVK Allows AMD's Deprecated Mantle API To Run Atop Vulkan [5] There are just a handful of games like Battlefield 4, Thief, and others that can make use of AMD's long-deprecated Mantle graphics API as the predecessor to modern graphics APIs like Vulkan and Direct3D 12. Mantle never was brought to Linux given the emphasis quickly turned to Vulkan within The Khronos Group, but now with the open-source "GRVK" project it's being mapped on top of Vulkan. Independent open-source developer Clément Guérin took to implementing Mantle on top of the Vulkan API largely as a learning exercise. But it does have the potential of helping the few games/engines supporting Mantle to potentially run faster under Wine / Steam Play than the likes of the D3D11 code paths, but that's yet to be determined given the initial release of GRVK does little more than correctly render a triangle. Mike Blumenkrantz: Xfb Redux [6] In the course of handling ARB_enhanced_layouts, I came across another interesting xfb- related issue: shaders are now allowed to specify all the xfb buffer info in the layout, and they?re also now allowed to set the location of the variable. And locations aren?t considered to overlap unless they have overlapping components. For those who recall so many years ago when I explored xfb integration in ntv, you know that this is a problem because I?ve been tracking xfb outputs based solely on the location. Security updates for Wednesday [7] Security updates have been issued by Debian (imagemagick and ruby-websocket-extensions), Fedora (libetpan, LibRaw, and php), Gentoo (nss), Mageia (apache, ark, clamav, claws-mail, dovecot, firefox, firejail, freerdp, golang, jasper, kernel, libssh, libx11, postgresql-jdbc, python- rstlib, radare2, roundcubemail, squid, targetcli, thunderbird, tomcat, and x11-server), Red Hat (rh-mysql80-mysql), SUSE (dovecot22, freerdp, libvirt, and postgresql12), and Ubuntu (curl and linux-hwe, linux-azure-5.3, linux-gke-5.3). Sophos EDR achieves Amazon Linux 2 Ready designation [8] Sophos is pleased to announce that it has achieved the Amazon Linux 2 Ready designation as part of the Amazon Web Services (AWS) Service Ready Program.

Librem 14 Features BIOS and EC Write Protection [3] We have been focused on BIOS security at Purism since the beginning, starting with our initiative to replace the proprietary BIOS on our first generation laptops with the open source coreboot project. This was a great first step as it not only meant customers could avoid proprietary code in line with Purism?s social purpose, it also meant the BIOS on Purism laptops could be audited for security bugs and possible backdoors to help avoid problems like the privilege escalation bug in Lenovo?s AMI firmware. Our next goal in BIOS security was to eliminate, replace or otherwise bypass the proprietary Intel Management Engine (ME) in our firmware. We have made massive progress on this front and our Librem laptops, Librem Mini, and Librem Server all ship with an ME that?s been disabled and neutralized. After that we shifted focus to protecting the BIOS against tampering.

    Tutorial Notes – Building User Interfaces With Video and 3D Graphics For Fun and Profit! Building User Interfaces With Video and 3D Graphics For Fun and Profit! Tutorial Notes Linux Conf Au 2005 Canberra, ACT, Australia By Wayne Piekarski [email protected] http://www.tinmith.net/wayne Wearable Computer Lab School of Computer and Information Science The University of South Australia Wayne Piekarski – Linux Conf Au – Canberra, ACT – April 2005 1 Tutorial Notes – Building User Interfaces With Video and 3D Graphics For Fun and Profit! Abstract With the availability of cheap video capture and 3D graphics hardware on most desktop computers, we now have the ability to investigate new ways of interaction that were previously beyond the reach of the average hobbyist at home. Rather than viewing everything on a 2D desktop, what possibilities exist for viewing information in 3D? Instead of using a keyboard and mouse, what other more intuitive ways are there to interact with a 3D environment? This tutorial gives an introduction to some of the less mainstream possibilities that are available on your Linux PC running at home right now. Linux is an ideal platform for performing this type of work with, since there is a wide range of existing source code which can be extended in any way that you can imagine. The purpose of this tutorial is to encourage developers to think of new possibilities for input devices and user interfaces for their computers. In order to support this, I will also cover some of the less used and understood subsystems available under Linux, including the DRI and OpenGL 3D interfaces in XFree86, accessing video cameras using Video4Linux and the 1394 Firewire drivers, using free libraries such as ARToolkit for 3D object tracking, libraries such as OpenCV for vision recognition, and scene graph libraries for rendering 3D graphics.
