Description Nayan Deshmukh 2016-10-20 12:43:41 UTC

I am using master branch of kernel. Tonga fails to initialize with the following error: 
 amdgpu: powerplay initialization failed
 [drm:amdgpu_device_init [amdgpu]] *ERROR* sw_init of IP block <amdgpu_powerplay> failed -22
 amdgpu 0000:04:00.0: amdgpu_init failed

I was previously using 4.8-rc2 and it was working fine.

Comment 2 Nayan Deshmukh 2016-10-20 12:54:36 UTC

I have an I+A system with Radeon R7 M260/M265 / M340/M360 (Topaz) card. I had tonga in the first comment by mistake

Comment 3 Christian König 2016-10-22 17:38:56 UTC

This is a regression, isn't it? So the first step should probably be to bisect which patch broke it.

Try to google for "git bisect" on how to do this.

Comment 4 Nayan Deshmukh 2016-10-22 17:57:00 UTC

My system hangs when I try to load the amdgpu module. It, however, loads initially during startup. I was planning to do a git bisect on Sunday. I will keep updating this bug with my findings.

Comment 5 Nayan Deshmukh 2016-10-30 16:44:39 UTC

I was not able to do the bisect as I was busy during the week, Now I have completed the bisect. Everything was working fine in 4.8-rc2 but in 4.9-rc2 topaz failed to initialize. When I tried using 4.8-rc3 I noticed another error. The amdgpu loads successfully but when I try to use it via vdpau it leads to errors. I will file another bug for that. I guess this bug need to wait sometime.

Comment 6 Alex Deucher 2016-11-09 23:27:17 UTC

Do the patches on https://bugzilla.kernel.org/show_bug.cgi?id=185681 fix the issue?

dmesg

With the new patches, powerplay is initialized but I get another bunch of errors the xserver also fails to start. I am attaching the dmesg, please let me know if you need any more info.

Comment 8 Alex Deucher 2016-11-10 16:20:18 UTC

Updated patches on the other bug.

Comment 9 Nayan Deshmukh 2016-11-10 18:41:27 UTC

The new patches fixes the issue, however I still get this error 

[ powerplay ] VBIOS did not find boot engine clock value 			in dependency table. Using Memory DPM level 0!

PS: I have tested this patches with the patch on this bug 98505
