  • Microsoft Update Blue Screen Error Fixing BSOD
    kyoceradocumentsolutions.us Microsoft Update Blue Screen Error Fixing BSOD March 2021 Microsoft Update Blue Screen Error What is causing the Blue Screen error when I print using the KX Driver? Kyocera as well as many other companies began getting reports of Blue Screen of Death (BSOD) incidents when printing. Microsoft released 2 updates this week, KB5000802 and KB5000808. The updates caused the crash. What has Microsoft done since this was reported? Microsoft has removed both updates from the automatic pushed update list. If your PC has not yet downloaded the update it will not install them. If you manually update your system from within Windows Update the 2 problem updates are still there and can be manually selected and installed. Do not do that until a complete fix is released if your PC is used for printing. Microsoft has left them up for manual install for users that have systems not used for printing. How do we fix a PC that has already been updated? The best solution is to uninstall the 2 Updates. Follow the directions below and remember to reboot when done. 1. Open a Command Prompt with Administrator rights. Click on the Start button and type cmd. The following will be displayed. 2 Microsoft Update Blue Screen Error 2. Click Run as Administrator on the right to open the Command Prompt Window. Accept the prompt to open with elevated rights and make changes to the computer. 3. In the Command Prompt enter the following command and press enter. – wusa /uninstall /kb:5000802 4. The Stand alone install will launch and remove the Update.

  • Acceleration of Applications with FPGA-Based Computing Machines: Code Restructuring
    FACULDADE DE ENGENHARIA DA UNIVERSIDADE DO PORTO Acceleration of Applications with FPGA-Based Computing Machines: Code Restructuring Tiago Lascasas dos Santos Mestrado Integrado em Engenharia Informática e Computação Supervisor: João M. P. Cardoso, PhD Co-supervisor: João Bispo, PhD July 31, 2020 c Tiago Santos, 2020 Acceleration of Applications with FPGA-Based Computing Machines: Code Restructuring Tiago Lascasas dos Santos Mestrado Integrado em Engenharia Informática e Computação Approved in oral examination by the committee: Chair: Prof. João Paulo de Castro Canas Ferreira, PhD External Examiner: Dr. José Gabriel de Figueiredo Coutinho, PhD Supervisor: Prof. João Manuel Paiva Cardoso, PhD July 31, 2020 Abstract Field-programmable gate arrays (FPGAs) can be used to accelerate performance-critical programs from a wide range of fields and still providing energy-efficient solutions. Programs written in high level languages, such as C and C++, can be compiled to FPGAs through High-level Synthesis (HLS). Although FPGAs benefit the most from parallel and data-streaming applications, efficient compilation to FPGAs is a problem for both tools and developers. Most applications do not follow these patterns, and extensive code restructuring and the use of HLS directives need to be applied to a program in order to take advantage of FPGAs. Code restructuring and the use of HLS directives often needs to be manually performed by an experienced developer, and as such there is a need to automate this process. This dissertation proposes a framework that automatically optimizes C code via directives, using a source-to-source compiler on a stage prior to HLS. This optimization is primarily applied by strategies that select, configure and insert directives on the code to be input to an HLS tool, e.g., Vivado HLS, in order to synthesize more efficient hardware accelerators.

  • Microsoft Security Update for January 2020 Fixes 49 Security Vulnerabilities
    Microsoft Security Update for January 2020 Fixes 49 Security Vulnerabilities Overview Microsoft released the January security update on Tuesday, fixing 49 security issues ranging from simple spoofing attacks to remote code execution, discovered in products like .NET Framework, Apps, ASP.NET, Common Log File System Driver, Microsoft Dynamics, Microsoft Graphics Component, Microsoft Office, Microsoft Scripting Engine, Microsoft Windows, Microsoft Windows Search Component, Windows Hyper-V, Windows Media, Windows RDP, Windows Subsystem for Linux, and Windows Update Stack. Of the vulnerabilities fixed by Microsoft's this monthly update, a total of eight critical vulnerabilities exist in the .NET Framework, ASP.NET, Microsoft Scripting Engine, and Windows RDP. In addition, there are 41 important vulnerabilities. Critical Vulnerabilities The following are eight critical vulnerabilities covered in this update. @NSFOUS 2020 http://www.nsfocus.com Windows RDP CVE-2020-0609、CVE-2020-0610 These two remote code execution vulnerabilities in the Windows Remote Desktop Gateway (RD Gateway) could be exploited by unauthenticated attackers. If the two vulnerabilities are exploited successfully, arbitrary code may be executed on the target system, allowing the attacker to install the program, view, change or delete data, or create a new account with full user rights. To exploit this vulnerability, an attacker needs to send a specially crafted request to the RD gateway of the target system via RDP. This update addresses these issues by correcting the way the RD gateway handles connection requests. For more details about the vulnerabilities and download updates, please refer to Microsoft's official security advisories: https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-0609 https://portal.msrc.microsoft.com/en-US/security-guidance/advisory/CVE-2020-0610 CVE-2020-0611 This is a remote code execution vulnerability in Windows Remote Desktop clients.

  • Scheduling, Thread Context, and IRQL
    Scheduling, Thread Context, and IRQL December 31, 2020 Abstract This paper presents information about how thread scheduling, thread context, and a processor’s current interrupt request level (IRQL) affect the operation of kernel- mode drivers for the Microsoft® Windows® family of operating systems. It is intended to provide driver writers with a greater understanding of the environment in which their code runs. A companion paper, “Locks, Deadlocks, and Synchronization” at http://www.microsoft.com/whdc/hwdev/driver/LOCKS.mspx, builds on these fundamental concepts to address synchronization issues in drivers.

  • How to Fix a Frozen Windows PC
    How to Fix a Frozen Windows PC Mashka/Shutterstock.com Windows PCs freeze for a variety of reasons. One instance might be a fluke, but repeated freezes suggest a problem you’ll want to fix. Here’s how to unfreeze and recover a stuck PC—and stop it from freezing again. How to Speed Up a Slow PC Volume 0% How to Unfreeze a Frozen Windows PC There are several ways you can recover your frozen PC, depending on what caused the problem. Sometimes, all you have to do is wait a few seconds—the PC might get hung up while doing some work and unfreeze itself a few seconds later. If a full-screen application, like a game, freezes and prevents you from leaving it, press Alt+F4. This closes the application if the game is just experiencing graphical problems, but it won’t work if the application has frozen completely. To see if the computer is still responding, press Ctrl+Alt+Delete. From this screen, you can open the Task Manager (and close any running applications), or log out of or restart your PC. If this screen doesn’t appear, you might not be able to recover your PC without rebooting it. If you can open the Task Manager, you might be able to recover from the freeze. (You can also press Ctrl+Shift+Esc to open the Task Manager.) Select the “Processes” tab—if you don’t see it, click “More Details.” Locate any processes using a lot of CPU—you can click the “CPU” column header to sort by CPU usage and see the most demanding processes at the top of the list.

Let’s focus on the bus infrastructure for now Device model data structures The device model is organized around three main data structures: ● The struct bus_type structure, which represent one type of bus (USB, PCI, I2C, etc.) ● The struct device_driver structure, which represents one driver capable of handling certain devices on a certain bus. ● The struct device structure, which represents one device connected to a bus The kernel uses inheritance to create more specialized versions of struct device_driver and struct device for each bus subsystem.
