Milestone One - A Working Frame-Buffer RadeonHD Graphics Driver for Amiga OS 4.x

Today (13 October 2008) I have successfully opened a screen using the Picasso96 RadeonHD driver. There are still a few issues to sort out. For example, the colour look-up tables are not set, resulting in some funny colours. Also, the 16-bit screen-modes do not display correctly. Nevertheless, this is an important milestone. It is now possible to open screens (including workbench) via this driver. Being just a frame-buffer driver, there is no hardware acceleration for graphics, meaning that all rendering must be performed by the CPU. As a result, dragging windows can be sluggish. Interestingly, compositing does work, but switching it off speeds up the system.

RadeonHD - First Screen

An image shown by a Radeon X1300 graphics card in an Amiga-oneToday marks the first milestone in the RadeonHD for Amiga OS 4 project. A Radeon X1300 graphics card has successfully been programmed to open a 1280x1024 true-colour screen and an image has been displayed. The graphics card was a VisionTek Radeon X1300 256MB PCI card that has been plugged into one of the PCI slots in my Amiga-one for over half a year now. With this success, I am now confident that I can, in time, write a proper Amiga OS 4.x driver for this card. Thus, this project is now revealed on this website for the first time.
