DISPLAY_PLANE_A_PRIMARY_A_ENABLE:
When this bit is set, the primary plane
will generate pixels for display. When set to zero, display plane A memory fetches cease
and display is blanked (from this plane) at the next VBLANK event from the pipe that
display A is assigned. The display pipe must be enabled to enable this plane. There is an
override for the enable of this plane in the Pipe Configuration register.
1 = Enable
0 = Disable

0b
RW
DISPLAY_A_GAMMA_ENABLE:
This bit should only be changed after the plane has
been disabled. It controls the bypassing of the display pipe gamma unit for this display
plane s pixel data only. For 8-bit indexed display data, this bit should be set to a one.
0 = Display A pixel data bypasses the display pipe gamma correction logic (default).
1 = Display A pixel data is gamma corrected in the display pipe gamma correction logic.

DISPLAY_A_SOURCE_PIXEL_FORMAT:
These bits should only be changed after the
plane has been disabled. Pixel formats with an alpha channel (8:8:8:8) should not use
source keying. Pixel format of 8-bit indexed uses the palette. Before entering the
blender, each source format is converted to 10 bits per pixel (details are described in the
intermediate precision for the blender section of the Display Functions chapter).
000x = Reserved.
0010 = 8-bpp Indexed.
0011 = Reserved.
0100 = Reserved.
0101 = 16-bit BGRX (5:6:5:0) pixel format (XGA compatible).
0110 = 32-bit BGRX (8:8:8:8) pixel format. Ignore alpha.
0111 = 32-bit BGRA (8:8:8:8) pixel format. (with pre-multiplied alpha color format)
1000 = 32-bit RGBX (10:10:10:2) pixel format. Ignore alpha.
1001 = 32-bit RGBA (10:10:10:2) pixel format. (with pre-multiplied alpha color format)
1010 = 32-bit BGRX (10:10:10:2) pixel format Ignore alpha
1011 = 32-bit BGRA (10:10:10:2) pixel format (with pre-multiplied alpha color format)
1100 = 64-bit RGBX (16:16:16:16) 16 bit floating point pixel format. Ignore alpha.
1101 = 64-bit RGBA (16:16:16:16) 16-bit floating point pixel format (with pre-
multiplied color format)
1110 = 32-bit RGBX (8:8:8:8) pixel format. Ignore alpha.
