How To Install golang-github-hodgesds-perf-utils-devel on Fedora 36
Introduction
In this tutorial we learn how to install golang-github-hodgesds-perf-utils-devel on Fedora 36.
What is golang-github-hodgesds-perf-utils-devel
This package is a go library for interacting with the perf subsystem in Linux. I had trouble finding a golang perf library so I decided to write this by using the linux’s perf as a reference. This library allows you to do things like see how many CPU instructions a function takes (roughly), profile a process for various hardware events, and other interesting things. Note that because the go scheduler can schedule a goroutine across many OS threads it becomes rather difficult to get an exact profile of an invididual goroutine. However, a few tricks can be used; first a call to runtime.LockOSThread to lock the current goroutine to an OS thread. Second a call to unix.SchedSetaffinity, with a CPU set mask set. Note that if the pid argument is set 0 the calling thread is used (the thread that was just locked). Before using this library you should probably read the perf_event_open man page which this library uses heavily. See this kernel guide for a tutorial how to use perf and some of the limitations. This package contains the source code needed for building packages that reference the following Go import paths – github.com/hodgesds/perf-utils
We can use yum or dnf to install golang-github-hodgesds-perf-utils-devel on Fedora 36. In this tutorial we discuss both methods but you only need to choose one of method to install golang-github-hodgesds-perf-utils-devel.

sudo dnf makecache --refresh
After updating yum database, We can install golang-github-hodgesds-perf-utils-devel using dnf by running the following command:
sudo dnf -y install golang-github-hodgesds-perf-utils-devel
Install golang-github-hodgesds-perf-utils-devel on Fedora 36 Using yum
Update yum database with yum using the following command.
sudo yum makecache --refresh
After updating yum database, We can install golang-github-hodgesds-perf-utils-devel using yum by running the following command:
sudo yum -y install golang-github-hodgesds-perf-utils-devel
How To Uninstall golang-github-hodgesds-perf-utils-devel on Fedora 36
To uninstall only the golang-github-hodgesds-perf-utils-devel package we can use the following command:
