Just to clarify, you aren't able to enable DC with your current Kconfig configuration, which prevents you from retrying on this ticket? If so, please just open a new bug rather than conflate the issue here. Once you're unblocked from testing DC with your configuration, we can look at this issue again.

I was going to open another ticket. Just mentioned it before. Still dc=1 isn't yet usable due to this: https://bugs.freedesktop.org/show_bug.cgi?id=103953#c7 I found out that the breakage was occurring due to kernel configuration options. I can provide a working and broken kconfig, but my money is on it wanting the amd iommu gart support even though the hardware isn't installed. This is loaded on demand by the amdgpu module. Disabling agpart didn't do much harm though. Would that affect performance if intel_iommu is enabled?

Ask me for the .config's for the kernel if you need them to replicate the defect if you need them.

https://bugs.freedesktop.org/show_bug.cgi?id=104274 --- Comment #10 from Jordan L --- Hi Luke, it actually looks like you're running with DC disabled. Can you also try with amdgpu.dc=1 explicitly set? Potentially there are issues in multiple IP blocks, though we fixed a driver unload issue recently with DC enabled.

https://bugs.freedesktop.org/show_bug.cgi?id=104274 --- Comment #6 from Luke McKee --- Harry I have tried the latest staging next 2 days ago. Suggest you see there is a long standing issue with powerplay and buggy AMI bioses that don't properly set up MMIO BAR regiions that need to be worked around by your driver becuase the vendor says a 2 year old motherboard is too old to support firmware updates, even if Intel ME is a massive security risk in support emails. I'm actually thinking you guys need to add linuxbios/coreboot support for your driver if available the way things are going: https://forum-en.msi.com/index.php?topic=298468.0 I think Polaris 11 with buggy bioses that dont' properly setup PCIE MMIO BAR ranges have hell with the amdgpu driver and powerplay (no fan control) cooked cards etc. With your new powerplay code it gets even worse maybe and just doesn't boot in this condition. I work OK on 4.14.20 but with exactly the same config and amdgpu-staging-next from last updated 4 days ago I get this mess. Feb 23 01:41:59 hojuruku kernel: [drm] amdgpu kernel modesetting enabled.

[Bug 104274] Unable to cleanly unload kernel module: BUG: unable to handle kernel NULL pointer dereference at 0000000000000258 (mutex_lock)
https://bugs.freedesktop.org/show_bug.cgi?id=104274 Michel Dänzer changed: What|Removed |Added CC||harry.wentl...@amd.com, ||jordan.laz...@amd.com --- Comment #2 from Michel Dänzer --- The problem in the original report was fixed by https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a072c5f896beba806b4b867d478e1b90f94ba29b . Comment 1 looks like a new issue in DC. Looks like this might be related to the core DRM code now only initializing fbdev compatibility when a display connection is detected, like the change above. Sverd, until the latter is fixed, maybe you can try if amdgpu.dc=0 helps. -- You are receiving this mail because: You are the assignee for the bug.___ dri-devel mailing list dri-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/dri-devel
