## igs

A basic driver for IGS CyberPro 2010 graphics controllers. Currently it only supports the VLB variant found in Rev. 5 [[shark]]s, adding support for PCI variants is trivial though and will be done if I ever get my hands on a [[netwinder]] or something similar. The driver supports basic acceleration via [[EXA]] ( screen-to-screen blits, rectangle fills and off-screen memory ), it relies on [[igsfb]] for mode setting and hardware cursor support.

The driver needs
    Option "MigrationHeuristic" "greedy"
otherwise some anti-aliased text won't show up. No idea why, since the hardware has no support for alpha-blending the driver makes no attempt to accelerate any of it.
