r654 FIFO_GET_ENGINE_CONTEXT_PROPERTIES (0x801707): return the real per-engine context geometry captured from the GSP on the physical backend - the client queries ZCULL geometry (engineId=8) at the end of every vkCreateDevice attempt and the generic all-zero reply failed its ZCULL-context buffer allocation (VKFAIL -3); with the handler the client proceeds through GR_CTXSW_ZCULL_BIND, GR_SET_CTXSW_PREEMPTION_MODE, VRAM allocs and MAP_MEMORY_DMA to the GR channel kick
