In the world of software development, the GNU Debugger (GDB) is an essential tool for programmers. It allows us to peer inside a running program, find bugs, and understand complex code. As new hardware architectures emerge, it's crucial that our tools keep pace. One such rising star is RISC-V, an open-source instruction set architecture that is rapidly gaining popularity, particularly with its new vector extensions for high-performance computing. The Challenge: An Unknown Ins

Performance analysis can often feel like searching for a needle in a haystack. When your application isn't running as fast as you'd like, where do you even begin to look? Is it a memory bottleneck? Are you stalling in the CPU's front-end? Answering these questions is critical, but traditional tools can be complex and overwhelming. This is where Intel's PerfSpect comes in. And now, thanks to some recent contributions, this powerful tool is no longer just for x86 systems. I'm h

Fuzzing RISC-V compilers like GCC and LLVM is a crucial practice for ensuring the correctness and security of the entire software ecosystem built on this architecture. It's not about finding vulnerabilities in the final compiled code, but rather about discovering bugs within the compiler itself that could lead to incorrect code generation, unexpected behavior, or even exploitable flaws. Why Compiler Fuzzing is a Unique Challenge  Fuzzing compilers is different from fuzzing a

JetStream is a JavaScript benchmark suite that evaluates web application performance by measuring the execution latency and throughput of complex workloads. With the release of JetStream 2.2, we at WhileOne Techsoft undertook the task of migrating its harness to a modern Node.js-based setup . Recently while working with a customer who was looking to benchmark their CPU using some js workloads. This post dives into why we did it, how we did it, and what you can expect from th

The Problem statement: Our customer expressed their desire to know if Android (AOSP) was already ported by community to the RiscV platform and if we could provide a detailed summary of the current status of AOSP compilation/build and Qemu emulation progress for RiscV Introduction to AOSP: Android is an open source operating system for mobile devices and an open source project led by Google. Android Open Source Project (AOSP) repository offers the information and source code

Kubernetes, also known as K8s, is an open-source system for automating deployment, scaling, and management of containerized applications. Kubernetes is an open source container orchestration engine for automating deployment, scaling, and management of containerized applications. The open source project is hosted by the Cloud Native Computing Foundation (CNCF).So if you are a developer and not familiar with kubernetes CLI, then the kubernetes client will help you to interact w

We at Whileone Techsoft pvt ltd understood the requirements of our customer who wanted to have a basic Yocto based RiscV deployment for their custom SoC chip. The customer intended to share this basic deployment with their clients who wished to make use of our customer’s SoC in their products.  Our customer was unaware of Yocto and what was needed to ensure a favorable deployment. They had their own custom patched Linux kernel, Root file system, Toolchain and custom Bootloade

Background: ​ For some months, we at WhileOne Techsoft Pvt. Ltd. have been helping our customer setup a system to validate the performance of their SoC platform. In this context, we had to bring up an aarch64 Linux based target image to run on their proprietary hardware SoC platform. Part-1 of this series explains how to build an External Toolchain with BuildRoot. Part -2   of this series explains how to build a Target Linux image and Rootfs in BuildRoot using the External T
