This would breaks IPU6. For TGL and ADL platforms, it has been fixed in bug 1958004 for oem-5.14 and above. This patch adds a new ID for RPL. [Fix] Use IOMMU passthrough mode for IPU6 as it has its own iommu hardware. [Test Case] Apply the fix and kernel should print a new info line: Passthrough IOMMU for integrated Intel IPU and IPU6 camera should continue to work without intel_iommu=off work-around. [Where problems could occur] No. That's what it should have been done. [Other Info] Nominates only oem-6.0 and unstable for we have RPL IPU6 enabled on oem-6.0 and newer. ========== original bug report ========== Per https://github.com/intel/ipu6-drivers/commit/89c6b99e4bec00a04b53f37cd8c3c01ce824a4ab, an additional quirk is necessary for Intel IPU6 on Raptor Lake as previous TGL/ADL do.
