Phoronix: A Number Of AMDGPU DRM Fixes Prepped Ahead Of Linux 4.19

Following AMD staging numerous AMDGPU DRM improvements in DRM-Next for Linux 4.19, they have moved onto further testing this code and providing various fixes for some of the early fallout to these changes ahead of the next kernel cycle...

So raven ridge will hopefully be stable in autumn?

Still not getting any audio from the display port on my Fury to my MG279Q monitor when playing 44.1khz content as of kernel 4.17.8. Always worked fine on Windows so there's got to be some issue somewhere.

Yes, as in it won't be mainlined until 4.19.

Uh? Not sure I understand. AMDGPU DC including HDMI and DP audio was mainlined in 4.15. My issue is that it only works for 48khz content, but not for 44.1khz and it doesn't seem like anyone is looking into it. Are you saying that 4.19 has a fix for this bug?

On Ryzen Mobile I would call Linux very usable. My system can't Suspend (varies a bit with the kernel I'm running + Fedora updates) and does have an occasional keyboard hang. However for my usage (programming, web, and video watching) it does very well. It has literally gotten better with each update from Fedora.

A quick edit: some of the problem s that are showing up might not even be AMD related, I've seen reports of various forums where Intel hardware has had similar issues.

So amdgpu Vega blanking woes will only be fixed in 4.19+? What about DisplayPort / Wayland issues?

Sounds like it might be a audio driver or application issue. Most HDA codecs only support 48khz. The CPU has to do the re-sampling for other rates I think.
