description:
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.
