Udeoo Team published a video about increasing the performance as the default configuration is set to Auto (15W TDP). But you can set TDP up to 25W to increase performance! Instructions (see also the video!): - When booting up, press ESC until the BIOS shows up; - Select Advanced from the top menu; - AMD CBS; - NBIO common options; - System Configuration; - 25W; Done.
Looks cool, probably increases performance, but doesn't work for Linux, at least for stock Ubuntu 20.04. Video is choppy and maybe 25 fps only. Any ideas how to debug this under Linux?
Did you install Ubuntu and used nomodeset option according the installation manual for 18.04? Because then you have no optimized driver. https://www.udoo.org/docs-bolt/Operating_Systems/Linux/Known_issues.html
Hmm, no, I have 20.04. I shall have later time to debug this further, according to old style gentoo hacker.
Ok, I verified the config: Stock Ubuntu 20.04 Linux 5.4.0-37-generic Module loaded amdgpu (GPL, signed, out of modinfo) No video related parameters passed through kernel cmdline bios 1.8, newest I am trying 4k 60 fps 2160p60, Costa Rica movie in YT, Firefox. This results in CPU running at 90%., significant frame loss, not able to watch. Dropping to 1440p60 is OK, plays fine. Exactly the same results can be observed in Chrome. However, downloaded the movie using YouTube-dl. VLC cpu usage is fluctuating, but video can't really played, again significant drops. Kodi plays same 4k file without any hiccup, cpu remains at level of 1.5 lavg, 18%. Soo I can live with Kodi, but I'd really like to use YouTube. How this could be possibly fixed?...
I have just installed Ubuntu 20.04 and everything looks fine. driver=amdgpu Youtube plays flawless on HD full screen Code: sudo lshw -c video *-display description: VGA compatible controller product: Raven Ridge [Radeon Vega Series / Radeon Vega Mobile Series] vendor: Advanced Micro Devices, Inc.

Let's stey even more precise: I am not trying to use you tube in HD (HD stands for 720p or 1080p since some time on YouTube). I am trying to play this video in youtube: in quality 2160p60, aka 4k. This goes very poor. As said, same movie downloaded can be nicely played in Kodi.
Did you try other browsers? There were issues in the past with YouTube players in browsers on Ubuntu or Linux in general.
Of course I tried, as written above. Ff and chrome, binary compilations. I also tried in Wayland and in different desktop environments, such as Mate, Gnome and Plasma. I can add that I have 16gb ram and 2tb fast nvme... Any ideas?
As far I know these browsers have VAAPI disabled, though there are guides how to enable it and have hardware acceleration one example is https://www.linuxuprising.com/2018/08/how-to-enable-hardware-accelerated.html had same problem with several other machines both x86 and ARMs
Thanks, this is it, jackpot. Firefox won't work without Wayland, Chromium also requires beta and some changes. I shall leave it as of now, unfortunately seems like Linux is still 2nd class citizen in browsers world. Fortunately Kodi is OK, and if I have any 4k movie, we'll, I'll download it first
