device-driver gt


gt is a 24-bit SBus-based color frame buffer and graphics accelerator. The frame buffer consists of 108 video memory planes of 1280×1024 pixels including 24-bit double buffering, 16 alpha/overlay planes, 24 z-buffer planes, 10 window id planes, 8 fast clear planes, and 2 cursor planes. It provides the standard frame buffer interface defined in fbio.4s paired with microcode which can be downloaded using gtconfig (8). Application acceleration is achieved via the Pixrect/Pixwin and SunPHIGS Application Programmer Interfaces (APIs).
