I have not bisected anything yet, but I am seeing issues on my Juno R2 with SCMI enabled power domains and Coresight AMBA devices.

I tried the hack you have suggested here(rather Tony's version), also tried with fw_devlink=0 and fw_devlink=1 && fw_devlink.strict=0 No change in the behaviour. The DTS are in arch/arm64/boot/dts/arm/juno-*-scmi.dts and there coresight devices are mostly in juno-cs-r1r2.dtsi Let me know if there is anything obvious or you want me to bisect which means I need more time. I can do that next week. -- Regards, Sudeep _______________________________________________ iommu mailing list iommu@lists.linux-foundation.org https://lists.linuxfoundation.org/mailman/listinfo/iommu
