Processor Graphics Display

The Processor Graphics controller display pipe can be broken down into three
components:

• Display Planes
• Display Pipes
• DisplayPort* and Intel

FDI

2.4.2.1

Display Planes

A display plane is a single displayed surface in memory and contains one image
(desktop, cursor, overlay). It is the portion of the display hardware logic that defines
the format and location of a rectangular region of memory that can be displayed on
display output device and delivers that data to a display pipe. This is clocked by the
Core Display Clock.

2.4.2.1.1

Primary Planes A, B, and C

Planes A, B, and C are the main display planes and are associated with Pipes A, B, and
C respectively.

2.4.2.1.2

Sprite A, B, and C

Sprite A and Sprite B are planes optimized for video decode, and are associated with
Planes A and B respectively. Sprite A and B are also double-buffered.

2.4.2.1.3

Cursors A, B, and C

Cursors A and B are small, fixed-sized planes dedicated for mouse cursor acceleration,
and are associated with Planes A and B respectively. These planes support resolutions
up to 256 x 256 each.

2.4.2.1.4

Video Graphics Array (VGA)

VGA is used for boot, safe mode, legacy games, and so on. It can be changed by an
application without operating system/driver notification, due to legacy requirements.
