The title of this post says it all; compositing for Radeon HD 2000-4000 graphics cards (R6xx-R7xx chipsets) is done. This is another milestone for the RadeonHD driver AmigaOS 4.x. Completion of this major feature puts the support for Radeon HD cards (R6xx-R7xx chipsets) almost on par with the support for the Radeon X1000 series (R5xx chipsets). I say almost because a few of the minor blitter acceleration functions,and DVI and VBlank interrupts are are still to do. As always, there is more work to do. Nevertheless, a composited Workbench performs well with these cards.

I am pleased to announce that compositing for R5xx based cards (Radeon X1000 series) is now done. This marks a major milestone in the development of the RadeonHD.chip driver. Namely, full 2D graphics acceleration is implemented for an entire series of graphics cards. The screenshot below shows  Workbench with compositing effects enabled being displayed by a Radeon X1550 graphics card. As you can see, the errors that were present in the previous screenshot are now gone (the development log entry containing the previous screenshot is included in the image below for comparison).

It has been a while since I posted an update about this RadeonHD driver for Amiga OS 4.x project. At present I am still working on implementing compositing for R5xx chipsets (Radeon X1000 series cards) but, there is progress. The screenshot shown below (and the thumbnail image to the left) was captured from a Radeon X1550 PCI card when running Amiga OS 4.1 with compositing enabled. As you can see, basic compositing is operational.
