NVIDIA Tegra Linux Driver Package RN_05071-R28 | 4 2.0 Fixed Issues The issues listed below are fixed in this release. In addition, security-related fixed issues are described in a separate Security Bulletin. 2.1 Bootloader Bootloader related resolved issues are as follows. Issue Description 2673421 U-Boot fails to run when using A/B redundancy and booting from B partition. 2.2 Graphics Graphics related resolved issues are as follows. Issue Description 200480591 Hang or crash with “mutex lock full” message when cuGraphicsEGLRegisterImage() is called and a buffer is initialized. NVIDIA Tegra Linux Driver Package RN_05071-R28 | 5 2.3 Kernel Kernel related resolved issues are as follows. Issue Description 200549114 USB loopback through device fails with timeout. Security fixes for this release may be found at: https://www.nvidia.com/en-us/security/ NVIDIA Tegra Linux Driver Package RN_05071-R28 | 6 3.0 Implementation Notes 3.1 Jetson TX2i Support The Jetson TX2i module on the Linux for Tegra Board Support Package is provided to support Jetson TX2i which is a Jetson TX2 module SKU suitable for industrial environments. The Jetson TX2i module has been supported since the 28.2 release, and will be supported in future releases. 3.2 Docker Support The kernel in this release is pre-configured to enable Docker. Docker is unsupported in ARM64, although NVIDIA has added kernel configuration support for dockers, where users can install the docker.io as required, dockers are not officially supported in arm64 architecture. Although, the dockers may be woking properly, the ubuntu launchpad at: https://launchpad.net/ubuntu/xenial/arm64/docker Identifies that the package contains the daemon and client using docker.io on non- amd64 hosts that is not supported. [2033135, 2001213] 3.3 Symlinks May be Overwritten by Installation of Third Party Libraries Installing third party libraries on the target device may overwrite the accelerated library provided by Linux for Tegra. NVIDIA Tegra Linux Driver Package RN_05071-R28 | 7 For example, installing Mesa EGL may create a /usr/lib/<arch>/libEGL.so symlink, overwriting the symlink to the implementation library that should be used instead, /usr/lib/<arch>/tegra-egl/libEGL.so. Linux for Tegra installs a boot-time initialization script /etc/init/nv.conf, that corrects typical occurrences, such as with OpenGL, EGL, and X11 GLX libraries. This script runs at boot and corrects typical occurrences. To workaround Reboot after installation of packages that install conflicting library symlinks. 3.4 Prerequisite for video_decode_drm Multimedia Sample video_decode_drm is a new sample in the Multimedia API that demonstrates how to render video stream or UI with the NVIDIA® Tegra® Direct Rendering Manager (DRM). [1843440] Before running the sample, you must ensure the Ubuntu desktop is disabled. To disable the Ubuntu desktop 1. Execute the command: $ sudo systemctl stop lightdm.service 2. If there are two display outputs, unblank the second inactive display, as follows: $ sudo sh -c 'echo 0 > /sys/class/graphics/fb1/blank' 3.5 Bluetooth Audio and Conformance Support Bluetooth audio is disabled in this release to ensure that the bluetooth software stack is conformant in the provided configuration. If additional bluetooth audio profiles are enabled, product conformance may be impacted [200276904]. For compliance information, consult the Jetson TX1-TX2 OEM Wireless Compliance Guide. For information on enabling Bluetooth Audio, see “Bluetooth Device Settings” in NVIDIA Tegra Linux Driver Package Development Guide.

    UKUI: a Lightweight Desktop Environment Based on Pluggable

    2016 International Conference on Artificial Intelligence and Computer Science (AICS 2016) ISBN: 978-1-60595-411-0 UKUI: A Lightweight Desktop Environment Based on Pluggable Framework for Linux Distribution Jie YU1, Lu SI1,*, Jun MA1, Lei LUO1, Xiao-dong LIU1, Ya-ting KUANG2, Huan PENG2, Rui LI1, Jin-zhu KONG2 and Qing-bo WU1 1College of Computer, National University of Defense Technology, Changsha, China 2Tianjin KYLIN Information Technology Co., Ltd, Tianjin, China *[email protected] *Corresponding author Keywords: Desktop environment, Ubuntu, User interface. Abstract. Ubuntu is an operating system with Linux kernel based on Debian and distributed as free and open-source software. It uses Unity as its default desktop environment, which results in more difficulties of usage for Microsoft Windows users. In this paper, we present a lightweight desktop environment named UKUI based on UbuntuKylin, the official Chinese version of Ubuntu, for Linux distribution. It is designed as a pluggable framework and provides better user experience during human-computer interaction. In order to evaluate the performance of UKUI, a set of testing bench suits were performed on a personal computer. Overall, the results showed that UKUI has better performance compared with Unity. Introduction Linux is a freely available operating system (OS) originated by Linux Torvalds and further developed by thousands of others. Typically, Linux is packaged in a form known as a Linux distribution for both desktop and server use. Some of the most popular mainstream Linux distributions are Red Hat [1], Ubuntu [2], Arch [3], openSUSY [4], Gentoo [5], etc. There are several desktop environments available for nowadays modern Linux distributions, such as XFCE [6], GNOME [7], KDE [8] and LXDE [9].

    Preprints (www.preprints.org) | NOT PEER-REVIEWED | Posted: 16 July 2021 doi:10.20944/preprints202107.0375.v1 Review Low-power Ultra-small Edge AI Accelerators for Image Recog- nition with Convolution Neural Networks: Analysis and Future Directions Weison Lin 1, *, Adewale Adetomi 1 and Tughrul Arslan 1 1 Institute for Integrated Micro and Nano Systems, University of Edinburgh, Edinburgh EH9 3FF, UK; [email protected]; [email protected] * Correspondence: [email protected] Abstract: Edge AI accelerators have been emerging as a solution for near customers’ applications in areas such as unmanned aerial vehicles (UAVs), image recognition sensors, wearable devices, ro- botics, and remote sensing satellites. These applications not only require meeting performance tar- gets but also meeting strict reliability and resilience constraints due to operations in harsh and hos- tile environments. Numerous research articles have been proposed, but not all of these include full specifications. Most of these tend to compare their architecture with other existing CPUs, GPUs, or other reference research. This implies that the performance results of the articles are not compre- hensive. Thus, this work lists the three key features in the specifications such as computation ability, power consumption, and the area size of prior art edge AI accelerators and the CGRA accelerators during the past few years to define and evaluate the low power ultra-small edge AI accelerators. We introduce the actual evaluation results showing the trend in edge AI accelerator design about key performance metrics to guide designers on the actual performance of existing edge AI acceler- ators’ capability and provide future design directions and trends for other applications with chal- lenging constraints.
