System information and perf data
Hi
I have configured my system to use the amdgpu kernel driver (note no
experimental support activated) on openSUSE Tumbleweed and running
4.8.0-rc2-3.gda13dfd-default. I did have to re-build the xf86-video-amdgpu to
add my Mullins R5 PCI-IDs. I don't see this when running the radeon driver.
Reproducible: Always
Steps to Reproduce:
1. Boot to Gnome desktop.
2. Set timeout for screen saver 1-15 minutes doesn't matter.
3. From a remote ssh session monitor via top and observe one cpu at ~100% when
screen save activates.
Actual Results:
I ran the following perf command to capture some data which will add as an
attachment;
perf record -F 250 -g -a sleep 10
perf report
Expected Results:
Not consume cpu when idle/screensaver mode.
Attachment includes;
20-amdgpu.conf, dmidecode.txt, perf_data_summary.txt, 4.8.rc3.perf.data,
os-release and Xorg.0.log
