…GPU iommu quirk BugLink: https://bugs.launchpad.net/bugs/2150487 Replace the explicit DGX Spark iGPU device ID list with a range check covering 0x2E00-0x2E3F to accommodate all possible DGX Spark iGPU PCI device IDs without requiring individual additions. The original quirk was introduced in commit ab85863 ("NVIDIA: SAUCE: iommu/arm-smmu-v3: Set DGX Spark iGPU default domain type to DMA") and extended with two more IDs in commit 8dc61ab ("NVIDIA: SAUCE: iommu/arm-smmu-v3: Add two more DGX Spark iGPU IDs for existing iommu quirk"). Using a range avoids further per-ID additions as new DGX Spark variants are introduced.

@nirmoy Is this needed for Vera? I thought these commits were only for Spark? |
I think there may have been some confusion. We started down the list of patches tracked in your spreadsheet. We're refocusing on what is currently available in 6.17. |
These patches will also be in 6.17 as it supports the Spark platform. AFAIK, the linux-nvidia-6.18 reference kernel does not need to support Spark (i.e. these are not needed on linux-nvidia-6.18 if they are Spark-only). |
Ack. 6.18 is from Vera and those patches are for Spark so we can ignore those patches for 6.18 kernel |

Add the DGX Spark iGPU device ID list with a range check covering 0x2E00-0x2E3F to accommodate all possible DGX Spark iGPU PCI device IDs without requiring individual additions.
