have you looked at tracy : https://github.com/wolfpld/tracy ?
it seems to at par, if not better than the other offering.

> I suspect that I have an outdated version of hotspot Linux profiler, but I can’t just go and download a fresh release from GitHub, because hotspot is a KDE app, and I use NixOS.
KDE (not to be confused with the Plasma desktop) is just a bunch of C++ libraries that can work on a variety of desktop environments and even OSes (though Hotspot being a perf report alternative is clearly meant for use with Linux).
I just went and downloaded the latest CI build from[0] and it ran just fine on my openSUSE Tumbleweed, running Xorg with Window Maker. I do have a bunch of KDE apps installed, like Kate (my currently preferred text editor), Dolphin (the file manager i use whenever i want thumbnails, usually for videos and images), Spectacle (for screenshots), Falkon (i use it as a "clean" browser to test out things), etc so i also do have the KDE libraries on my system, but that is just a `zypper install` away. Or an `apt-get install` or `pacman -S` or whatever package manager your distro uses, i've used a bunch of them and they all pretty much behaved the same. I'd expect Hotspot to be installable in the same way in any of them.
If there are issues with NixOS (i don't know, i haven't tried it) i think it might actually be a NixOS issue and not a KDE issue.

Project mention: Apple's new Processor Trace instrument is incredible | news.ycombinator.com | 2025-08-16
Intel has a Performance Monitoring Unit on its core that has significant overlap.
Forgetting this tool-space, but at least some of these tools can make use of that hardware:

perf-cpp
Lightweight recording and sampling of performance counters for specific code segments directly from your C++ application.
Profiling tools play a crucial role in identifying bottlenecks and aiding developers in optimizing their code. Yet, the broad granularity often means that key code segments tracked with perf stat can be obscured by extraneous data. Libraries like PAPI, PerfEvent, and perf-cpp offer a solution by allowing direct control over hardware performance counters from within the application itself. By leveraging the perf subsystem (more precisely the perf_event_open system call), these tools enable precise measurements of only the code segments that are truly relevant.
