None of the hardware supported by amdgpu exposes anything like that anymore. The rest is mainly for profiling and debugging. For more information see the relevant kernel documentation: https://www.kernel.org/doc/html/latest/gpu/amdgpu.html#gpu-power-thermal-controls-and-monitoring I don't think there is anything you'd want to tweak there.

[PATCH] drm/amd/display: add debugfs entry for trigger_hotplug
The 'trigger_hotplug' entry in debugfs is defined but not wired up. This
causes a gcc warning build with W=1.

first bad commit: [fc8c70526bd30733ea8667adb8b8ffebea30a8ed] drm/radeon: Prefer lower feedback dividers
Hi, this patch breaks X on my box - it is fully responsive and I can log in into it from another machine but both monitors are black and show this: "The current input timing is not supported by the monitor display. Please change your input timing to 1920x1200@60Hz or any other monitor listed timing as per the monitor specifications." Reverting it fixes the issue. Thx. -- Regards/Gruss, Boris. https://people.kernel.org/tglx/notes-about-netiquette ___ amd-gfx mailing list amd-gfx@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/amd-gfx

This is not going to do what you want. The pci revision id is not the
same as the ati rev id. If you actually want the pci revision id, we
already have it in adev->pdev->revision, no need to fetch it directly.

[PATCH] amdgpu/gmc_v9: Warn if SDPIF_MMIO_CNTRL_0 is not set
With IOMMU enabled, if SDPIF_MMIO_CNTRL_0 is not set
appropriately the system hangs without any trace
during S3.
To ease debug and to ensure that the failure, if any,
was caused by a race conditions that disabled write access to
SDPIF_MMIO_CNTRL_0 register, warn the user about it.
