Secondary surface address for secondary graphics in byte. It is 4K
byte aligned.
NOTE: Bits 0:10 of this field are hardwired to ZERO.
Default
0x0
Secondary graphic surface pitch in pixels. For Micro-tiled/Macro-tiled
surface, it must be multiple of 64 pixeld in 8bpp mode. For Micro-lin-
ear/Macro-tiled surface, it must be multiple of 256 pixeld in 8bpp
mode, multiple of 128 pixels in 16bpp mode and multiple of 64 pixels
in 32bpp mode. For Micro-linear/Macro-linear surface, it must be mul-
tiple of 64 pixels in 8bpp mode. For other modes, it must be multiple
of 32.
NOTE: Bits 0:4 of this field are hardwired to ZERO.
Default
0x0
Secondary graphic X surface offset. It is 256 pixels aligned.
NOTE: Bits 0:7 of this field are hardwired to ZERO.
