Normally softwareshutdowntemp should be greater than Thotspotlimit. However, on some VEGA10 ASIC, the softwareshutdowntemp is 91C while Thotspotlimit is 105C. This seems not right and may trigger some false alarms.

The values for "se_num" and "sh_num" come from the user in the ioctl. They can be in the 0-255 range but if they're more than AMDGPU_GFX_MAX_SE (4) or AMDGPU_GFX_MAX_SH_PER_SE (2) then it results in an out of bounds read.

[Why] DC uses these to raise the voltage as needed for higher dispclk/dppclk and to ensure that we have enough bandwidth to drive the displays. There's a bug preventing these from actuially sending messages since it's checking the actual clock (which is 0) instead of the incoming clock (which shouldn't be 0) when deciding to send the hardmin.

We still have a few iommu issues which need to address, so force raven as "dgpu" path for the moment. This is to add the fallback path to bypass IOMMU if IOMMU v2 is disabled or ACPI CRAT table not correct. v2: Use ignore_crat parameter to decide whether it will go with IOMMUv2. v3: Align with existed thunk, don't change the way of raven, only renoir will use "dgpu" path by default. v4: don't update global ignore_crat in the driver, and revise fallback function if CRAT is broken. v5: refine acpi crat good but no iommu support case, and rename the title. v6: fix the issue of dGPU initialized firstly, just modify the report value in the node_show().
