They are based on Peter's series which fixes handling of NSTable: https://lore.kernel.org/qemu-devel/20230714154648.327466-1-peter.maydell@linaro.org/ Running a Realm guest requires components at EL3 and R-EL2. Some rough support for TF-A and RMM is available here: https://jpbrucker.net/git/tf-a/log/?h=qemu-rme https://jpbrucker.net/git/rmm/log/?h=qemu-rme I'll clean this up before sending it out. I also need to manually disable FEAT_SME in QEMU in order to boot this, otherwise the Linux host fails to boot because hyp-stub accesses to SME regs are trapped to EL3, which doesn't support RME+SME at the moment. The right fix is probably in TF-A but I haven't investigated yet.
