about

_gpu_dxg_r4e_wait_recon.nx -- SOVEREIGN-GPU R4e RECON: confirm the paging fence ADVANCES to the map's paging_fence_value (i.e. the GPU actually completes the async VA mapping). Chain: device -> paging queue (capture fence_cpu_virtual_address@16) -> EXISTINGHEAP alloc -> MAPGPUVIRTUALADDRESS (ret=259 STATUS_PENDING, returns gpu_va + paging_fence_value) -> spin-read *(u64*)fence_cpu_va until it reaches paging_fence_value. Print initial fence, target, final fence, iters. raw syscalls only. license_tier: ORIGINAL
