NOTE: This blog gives a "behind the scenes look" at the progress of the RadeonHD driver's development. As such, its contents reflect the state of the development version of the driver, and not the state of the publicly released version.

The RadeonHD_RM.resource

A while ago I mentioned the RadeonHD_RM.resource, and said that I'd give more details later. Several posts to this development log have come since, without a mention about this resource. Today, I'm going to deliver those details, and provide a glimpse of what is still to come.

DVI output for Radeon HD 4000 series cards

I am pleased to announce that the RadeonHD driver for AmigaOS 4.x can now also output to DVI on Radeon HD 4000 series cards. Apart from being another item ticked off the driver development to-do list, from a personal perspective this means that I can now use my 4-port DVI KVM switch fully. Previously, switching to my Sam460ex would mean the monitor switching to the VGA output, and then manually switching to DVI again when switching back to another machine. The button on my monitor for switching inputs has already lost its "click" sensation due to the large amount of switching, so I am glad to hand that task over to the KVM.

Radeon HD 2000-4000 Compositing is Operational

An image of a composited Workbench screen on a Radeon HD 4650The 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.

Radeon HD 2000-4000 Series 2D Hardware Acceleration

It has been almost a year since I last posted an update to this driver development log. This was never intended, and my apologies to anyone who was hoping for more regular updates. Things have been rather hectic, and I had decided early on to only post updates when there is something concrete to show. Updates about how many lines of code have been written are boring. That's not to say that there have not been any milestones reached along the way; just that they have been "internal" milestones, which are less interesting to users. Anyway, an update is long overdue, so here it is.
