Hi, I'm currently implementing GuC/HuC firmware support in one Safety Critical OS. I'm following i915 code and I implemented all paths (I don't want GuC submission or SLPC features). I need GuC to authenticate HuC firmware blob. I mirrored GuC implementation in my code. After GuC DMA transfer succeeds, I'm reading GUC_STATUS register. HW returns INTEL_BOOTROM_STATUS_JUMP_PASSED as bootrom status and INTEL_GUC_LOAD_STATUS_LAPIC_DONE as GuC load status. Unfortunately, after one second of waiting, the status didn't get changed to INTEL_GUC_LOAD_STATUS_READY at all. What is a potential issue here? Could you please help me? In addition to this, could you please point out some documentation about GuC's ADS struct? Thanks, Maksym
