Properly define this register using a relative offset rather than an absolute offset and use the proper SOC15 macros to access it. It's also DCN, not DCE, so remove it from the DCE12 header. No functional change. Acked-by:

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().

drivers: gpu: amd: Initialize amdgpu_dm_backlight_caps object to 0 in amdgpu_dm_update_backlight_caps In `amdgpu_dm_update_backlight_caps()`, there is a local `amdgpu_dm_backlight_caps` object that is filled in by `amdgpu_acpi_get_backlight_caps()`. However, this object is uninitialized before the call and hence the subsequent check for aux_support can fail since it is not initialized by `amdgpu_acpi_get_backlight_caps()` as well. This change initializes this local `amdgpu_dm_backlight_caps` object to 0. Reviewed-by:

[Why] These aren't stable on some platform configurations when driving multiple displays, especially on higher resolution. In particular the delay in asserting p-state and validating from x86 outweights any power or performance benefit from the hardware composition. Under some configurations this will manifest itself as extreme stutter or unresponsiveness especially when combined with cursor movement. [How] Disable these for now. Exposing overlays to userspace doesn't guarantee that they'll be able to use them in any and all configurations and it's part of the DRM contract to have userspace gracefully handle validation failures when they occur. Valdiation occurs as part of DC and this in particular affects RV, so disable this in dcn10_global_validation. Signed-off-by:
