SUSE Linux Enterprise High Availability Extension 11 SP3 Situation Resource tracing can help to understand why a resource operation is failing. When enabled it will provide some debug output files. Often the OCF return codes are not enough to fully understand the failure. ...
If you're running a kernel version that supports it, you can (and should) take advantage of live kernel patching. This code execution method works alongside kernel probes and function tracing. Instead of relying on redirection using a breakpoint for kernel probes or a predefined location (in t...
This chapter takes you deeper into the relationships between processes, the kernel, and system resources. There are three basic kinds of hardware resources: CPU, memory, and I/O. Processes vie for these resources, and the kernel’s job is to allocate resources fairly. The kernel itself is al...
As Linux users, we often work with long-runningbackground Linux processes, which are called daemons or services. Some of the common examples of the services areSecure Shell (sshd), Network Manager (networkd), Volume Manager (LVM),Cron, and the list goes on. Many times we need tomonitor ...
It might be tempting to enable DirectX12 for DLSS/Raytracing. I found it saturates VRAM completely and produces blurry textures as a result. I prefer to leave it off and instead manually change the render resolution u can use -dx11 or -dx12 to launch the game without going through the lau...
Understanding the Linux Kernel Scheduler A kernel scheduler is a component of the kernel responsible for selecting the most appropriate process to run next from all the processes that are ready to execute. It manages the allocation of CPU time among these processes on the system. A process is ...
How does traceroute work in Linux? The complexity of tracing a route of a packet moving from source to destination depends on the number of interactions that packet has to face in the route. For an instance, in case a LAN is been used, the path traversed might be somewhat simple. The ...
In short, when running a recent hypervisor kernel, AVIC can be enabled by loading thekvm_amdmodule withavic=1. All KVM guests will then enable both SVM and IOMMU AVIC functionality, unless restricted via kernel parameters or inhibited due to specific guest configurations that are not supported ...
In this tutorial, we will show you how to run a traceroute from your Ubuntu operating system. A traceroute is a way of tracing the path your Ubuntu’s network connection takes to get to its destination. LATEST VIDEOS This video cannot be played because of a technical error.(Error Code:...
