So I've repeatedly tried with the current state of the NV patches[1], on both an ARMv8.0 system (Seattle) and an ARMv8.2 pile of putrid junk (vim3l). PSCI is pretty happy, although I can only test with at most 8 vcpus (GICv2 gets in the way). Can you please: - post the detailed error by running the PSCI unit test on its own - test with the current state of the patches Thanks, M.
