Hello! I have a Lenovo Flex 5 with a 4700u. I have downloaded the 4700u drivers (20.9.1) from the AMD driver website. When I look at the "check for windows updates" tab there's an option to install AMD display drivers 27.20.1020.1. Should I install these drivers alongside the other one? Should I uninstall the 20.9.1 driver and install this one instead? Or should I just keep the 20.9.1?

We are not officially supporting APUs via pre-built drivers on amd.com - there hasn't been much demand other than for OpenCL - but we test and upstream APU driver support before launch into kernel, libdrm, mesa etc...

The packaged drivers should work on Renoir, but if you have a reasonably current distro (rolling release, Ubuntu 20.10, Fedora 33 or downstream) then you should have full driver support included in the distro.

I'm facing video & audio stuttering on my Lenovo Ideapad 5 with Ryzen 7 4700U processor at times, but it gets fixed with reboots. Please let me know if you'd like some more information from my setup. I recently bought this machine from Amazon & removed Windows & installed Ubuntu.

I'm glad that your team is likely already working on providing Linux drivers(I recently got rid of a 7th Gen Intel corei5, I'm in for a ride hoping for a better CPU) , please let me know if there is a public bugzilla where I can file issues or a mailing list where I can send out my system info & other helpful debugging information directly to AMD developers. I missed capturing the dmesg output with the text amdgpu, I'll do that next time in addition to the things you'd like to have from my system when this issue occurs again. There are videos on YouTube which do claim similar issues. I'd be more than happy to help.

I don't know whether the Vega iGPU can be used to accelerate Plex transcoding. In theory it ought to be possible but only if Plex has been coded to make use of it. However, it's much more powerful than any Intel iGPU and I would like to see the driver included so that containers such as FoldingAtHome can make use of its OpenCL capabilities.

I have read reports that the Vega iGPU can be used for transcoding in the plex forums, however with it being quite a niche situation where you have a plex server, AND one of the very few CPUs with the vega iGPU, reports are few and far between.

I find it marvelous that you would go this length to build these drivers without even owning an AMD! I own a ryzen 2400g and tried to install your package. It would install (or so it says), but there is no existence of any /dev/dri when I look for it. Shouldn't it simply show up when I enter the command ls /dev? I did try a reboot to no avail. Should I go ahead and pass /dev/dri to the plex server container anyway?

Yes, subject, of course, to the containers' ability to make use of them. You mention transcoding, but AMD GPUs aren't currently officially supported by Plex - see the blue box on this page: -using-hardware-accelerated-streaming/

which shows that it's using both hardware decoding and encoding. It works fine for all type of media, except this particular type (4K HDR). If you enable HDR Tone Mapping in Transcoder Settings it forces software transcoding but the colours are rich. If you disable HDR Tone Mapping it allows hardware transcoding but the colours are weak and washed out. I don't have much HDR material at the moment, anyway.

Although support hasn't been added by the Plex devs yet, you can switch back to the lastest version of the application and the latest version of mauimauer's container now. The only thing that doesn't work is HDR tonemapping. -hw-transcoding-to-work-with-libva-vaapi-on-raden-apu-ryzen-7-4700u/676546/38
