0x0 Primary display hardware cursor enabled.
0=disable
1=enable
0x0 Primary display hardware cursor mode.
For 2bpp mode, each line of cursor data is stored in memory as 16
bits of AND data followed by 16 bits XOR data.
For color AND/XOR mode, each pixel is stored sequentially in mem-
ory as 32bits each in aRGB8888 format with bit 31 of each DWord
being the AND bit.
For the color alpha modes the format is also 32bpp aRGB8888 with
all 8 bits of the alpha being used.All HW cursor lines must be 64 pix-
els wide and all lines must be stored sequentially in memory.
0=Mono (2bpp)
1=Color 24bpp + 1 bit AND (32bpp)
2=Color 24bpp + 8 bit alpha (32bpp) premultiplied alpha
3=Color 24bpp + 8 bit alpha (32bpp)unmultiplied alpha
0x0 Primary display hardware cursor 2x2 magnification.
0=no 2x2 magnification
1=2x2 magnification in horizontal and vertical direction
0x0 Primary display hardware cursor surface base address in byte. It is
4K byte aligned.
NOTE: Bits 0:11 of this field are hardwired to ZERO.
0x0 Primary display hardware cursor height minus 1.
0x0 Primary display hardware cursor width minus 1.
0x0 Primary display hardware cursor X coordinate at the hot spot relative
to the desktop coordinates.
0x0 Primary display hardware cursor X coordinate at the hot spot relative
to the desktop coordinates.
