Phoronix: Linux 4.15-rc1 Kernel Released

While when releasing Linux 4.14 Linus Torvalds mentioned 4.15-rc1 might be delayed due to his US holiday travels, Linux 4.15-rc1 has been released on time to conclude the two week merge window process...

Just upgraded, performance in actual OpenGL applications seems to be fine, but I noticed I couldn't even move windows around smoothly. Apparently this broke vsync'd window management with compton (a compositor for WMs), especially the opengl-swc and opengl-mswc methods of vsync. The other methods of vsync took a huge performance hit and results in windows not being able to be moved smoothy, no problems on 4.14. I know early release candidates can be pretty buggy, I'll give it some more time and wait for rc2. Maybe some userspace packages need to be updated too.

Using an RX460 on Arch.

RX480 here and 4.15-rc1 on Ubuntu 17.10 and Mesa 17.2.4 is running buttery smooth for me with the amdgpu.dc=1 setting. HDMI Audio working as well. I can't wait til FreeSync makes it in.

Do SI cards benefit from amdgpu.dc=1 now or will be in the future ?

debianxfce I know the timers api was refactored in 4.15, that's likely the source of your problem. Here's the patch that did the refactoring (there may be others): https://patchwork.kernel.org/patch/10074919/

So I just tried the spin from Ubuntus mainline repository, and DP audio from my Fury to my MG279Q is still not working unless I resample everything to 48khz.

A quick update on my end: Night Light in GNOME is currently not working and I experienced a freeze (had to reset computer) a few seconds after resuming from Standby.

I have to say, I'm a bit disappointed this (https://bugs.freedesktop.org/show_bug.cgi?id=103489) regression I reported a month ago, which causes my machine to lock-up 100% of the time when my 4k TV is enabled, made it into -rc1.

Yeah, setting gamma/color-temperature is broken for me as well.
