Oh, as a last thought. The Efika would make a nice Amiga netbook


It was not the CPU that made the A1 expensive and problematic. There is no CPU shortage, there is just a shortage of reliable boards supported by AOS4.

A market of maybe 2000 AmigaOS4 fans is to small for an own board design.

If AOS4 would support some used PPC-Macs there would be enough hardware to satisfy the Amiga market for the next four years.

but Catalyst is a binary driver that has since been abandoned by ATI.

Who the h*ll is going to pay for switching AOS4 to a better CPU!?

Why do you keep ignoring the most important and obvious question of all?

I'll tell you why.. because you can't answer it!

Ok. so that part wasn't entirely correct. Which is weird, as I got it from the Xvmc project page.

However, the question still stands: how does this affect Hyperions decision to choose CPU family for AmigaOS? It's still a closed source binary release for Linux. Do you propose to include a Linux emulator inside AmigaOS?

And it seems UVD is enabled but not actually WORKING in catalyst. So I still ask you. Can you point to someone who has actually succeeded in USING GPU acceleration for video decoding outside a Windows environment?

Using "voltage" instead of "potential", which leads to inventing new words like "amperage" instead of "current" (I, measured in A) or possible "charge" (amperehours, Ah or Coulomb, C). Sometimes I don't even know what people mean.

Sorry for intervening here.

Nobody has succeded in regard to GPU-accelerated video with ATI-cards. But GPU-accelerated video is quite common with Linux. Devices from Nvidia, Intel and VIA are supported. Not that ATI couldn't be supported but it really does require documentation. Hyperion could buy access to that, though.

DoesSAM440 support PPCs with Altivec? Until AOS4 is officially available for PS3/PowerMac G5/iMac G5/'etc', the target users has make do with SAM440.

The point with the GPU focus to reduce the influence of weak CPU performance.
In summary, you have SAM440 with PCI slots. These PCI slots could support Radeon HD 2400 or HD 3400 PCI.

Note that, I’m not commenting on X86 switch.

Yes of course, if you find a PCI card with Altivec you can plug it directly into the system[/irony]

Why ? Is there any reason why target users could not use their A1, µA1 or PegasosII ?

The GPU won't help you, the drivers for 3D accelaratioin are usually closed source an the source for the access of the GPU are even closer and the GPU are not PPC compatible.

AMD have released the GPU documentation for R5xx and R6xx/R7xx chipsets. Otherwise I wouldn't be working on drivers (2D only at the moment). It's going to take a while, but we'll get there. Hopefully by the time I get that far, an open-source OpenCL effort will have been started; if not, we should start one.
