OP-TEE based PAS service relies on the linux driver to configure the iommu (just as it is done on the no_tz case). This generic patch does not cover that requirement. Because of that, it is probably better if the commit message doesnt mention OP-TEE and instead maybe indicate that PAS wll support TEEs that implement the same restrictions that QTEE (ie, iommu configuration). I can send an RFC for OP-TEE support based on the integration work being carried out here [1] [1] https://github.com/OP-TEE/optee_os/pull/7721#discussion_r3016923507 > > Along with that pass proper PAS ID to set_remote_state API.
