==== GR Error Code Format ====
When <code>type == 2</code> (GR Error), the returned data is formatted as follows:
  struct {
    __out u32 type;      // 2=gr_error
    __out u32 intr_value; // Interrupt bits
    __out u32 addr;      // Register address (in bytes)
    __out u32 data_hi;    // Data high 32 bits
    __out u32 data_lo;    // Data low 32 bits
    __out u32 class_num;  // GPU class number (e.g., 0xb197 for MAXWELL_B)
  };
