From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Videos stuttering across all applications (infosec.pub)

submitted 10 months ago by [email protected] to c/[email protected]

For a little over a month now, when playing videos on firefox, VLC, or any other application, I get infrequent stutters. This is with or without hardware accelleration. It's as if the video pauses briefly. If multiple videos are playing, even across different applications, each of them will be effected at the same time.

There are still a number of clock sync issues with the Zen4 chips. I've had issues on 6.4/5/6 with similar sounding audio/video that I've been able to somewhat mitigate by getting my amd_pstate settings to stop competing with other power tuning tools. Turn off EVERYTHING you have running dealing with cpufreq management, and just let the kernel amd_pstate do it's thing. No TLP, no desktop tuning tools, just the upstate.

Also, double check that your memory frequencies aren't bouncing all over the place, and consider under locking in the BIOS to exactly match the channel freq for CPU/mem.

See if that helps.

I believe the only power tuning I had was cpupower. I just stopped it and will give it some time. Do you know a tool that'll graph out my memory frequency? My memory seems pretty stable at 4800 MHz but I'll watch it with "watch lshw -short -C memory"

Issue still occured. Didn't see my memory fluctuating either
