_gpu_dxg_r2_recon.nx -- SOVEREIGN-GPU ladder R2 RECON (adapter-open from LUID).
R0 enumerated, R1 identified the discrete RTX 5080 by its ADAPTERTYPE bit. R2 takes the IDENTITY
(the discrete adapter's LUID) and opens a fresh kernel ADAPTER HANDLE for it through the raw
/dev/dxg ioctl LX_DXOPENADAPTERFROMLUID -- the precursor to LX_DXCREATEDEVICE (R3).
ABI (WSL2-Linux-Kernel linux-msft-wsl-6.6.y, include/uapi/misc/d3dkmthk.h):
#define LX_DXOPENADAPTERFROMLUID _IOWR(0x47, 0x01, struct d3dkmt_openadapterfromluid)
= (3<<30)|(12<<16)|(0x47<<8)|0x01 = 0xC00C4701 (recon-pinned in R1 pass)
struct winluid { __u32 a; __u32 b; } // 8 bytes
struct d3dkmt_openadapterfromluid { struct winluid adapter_luid; d3dkmthandle adapter_handle; }
-> luid @0 (8B, IN), adapter_handle @8 (4B, OUT) // 12 bytes
This is RECON ONLY: it prints the REAL ioctl return + the opened handle + a tamper matrix so the
gate can author a verdict. It writes NOTHING to the status log. raw syscalls only (no libc/vulkan/cuda).
