Bug ID: 108704 Summary: 4.19 amdgpu Tonga powerplay regressions Product: DRI Version: unspecified Hardware: x86-64 (AMD64) OS: All Status: NEW Severity: normal Priority: medium Component: DRM/AMDgpu Assignee: dri-devel@lists.freedesktop.org Reporter: daniel@constexpr.org
Created attachment 142423 --> https://bugs.freedesktop.org/attachment.cgi?id=142423&action=edit dmesg output
With Gentoo's 4.19.0 and 4.19.1 kernels, powerplay does not seem to be working on my Radeon R9 380X card: 3D applications run noticeably slower than before (but otherwise work fine) and there a number of errors in dmesg during startup and when trying to switch dpm states via sysfs.
Everything works fine with 4.18.17-gentoo.

--- Comment #5 from Bjorn Helgaas bhelgaas@google.com --- Could somebody please attach "sudo lspci -vvxxx" output for an affected system (for at least the root port and GPU, or the whole system if that's easier)?

I think I'm affected by a similar issue. I'm using an AMD R9 380 on Arch Linux with the latest GNOME version. My main troubles are with dual-screen, which started malfunctioning some days ago - maybe since the 4.19 kernel update, although I'm unable to downgrade to an older kernel to confirm this.

Please try the patch in comment 1.
I've applied the patch and there are no more amdgpu related errors showing up in dmesg after booting. However, this has not fixed my dual-screen issues; my HDMI TV displays "no signal" after booting while plugged in my computer, and when trying to switch display modes using the GNOME control center, my DVI screen tends to get disabled and display "no signal" too, forcing me to hard reboot. As far as I can tell, this is the same behavior than before using the patched kernel. So, my issues may not be related to this bug ticket after all.

Please file a different bug for the display issue.
