15:15 <calebccff> vkoul: ok, thanks :)

15:21 <z3ntu> Hey, I'm struggling to find the "origin" of the iommus value used in the ufs_mem_hc nodes, e.g. https://github.com/torvalds/linux/blob/master/arch/arm64/boot/dts/qcom/sm8250.dtsi#L2011 and https://github.com/torvalds/linux/blob/master/arch/arm64/boot/dts/qcom/sdm845.dtsi#L2255 . I just can't find e.g. the 0x4e0 in downstream sources at all or anything that would be an iommu definition. My iommu knowledge is super limited so I might be missing

15:21 <z3ntu> something obvious.. Anybody have any suggestion?

15:46 <bamse> z3ntu: iirc qualcomm sets up the iommu to do bypass for those from the bootloader, and then they just don't reset the iommu and hope that it all works

15:48 <bamse> z3ntu: so if you dump the smr registers in the arm smmu driver before it clears the registers, you'll typically find usb, ufs and display...and you just need to figure out which is which

15:59 <z3ntu> bamse: hm that's useful to know..
