A driver for the Permedia 2 graphics processor, so far it's been tested only on sparc64 with a Sun PGX32 / TechSource Raptor GFX 8P So far it accelerates block copies, rectangle fills and the cursor, it supports the usual wsdisplay / vcons stuff. TODO: - character drawing by hardware so we don't need to map the framebuffer - DDC2 support - mode setting This driver still relies on the firmware to set up graphics modes etc. so it won't work on x86 ( or non-OpenFirmware for that matter ) unless you use the VESA BIOS to set up graphics and pass the right properties ( width, height etc. ) to the driver. For the same reason it will work only if it's the OpenFirmware console.
