DESCRIPTION

The igmafb driver provides support for integrated graphics functions in Intel chipsets and provides an interface for the machine independent wscons(4) driver.

Currently igmafb configures the display for the integrated panel in notebooks and can control the backlight. Automatic detection of the main display on desktop machines may or may not work.

Supported hardware includes:

• GMA 900 (915G)
• GMA 950 (945G)
• GMA 3000 (Q965)
• GMA X3000 (G965)
• GMA X3500 (G35)
• GMA X4500 (G45)
• HD (Westmere)
• HD2000/3000 (Sandy Bridge)
• HD2500/4000 (Ivy Bridge)

BUGS

The driver conflicts with genfb(4), agp(4), and thus with drm(4). Support for a hardware cursor is missing.
