Any news about a new AmigaONE Linux Kernel, with DMA and 3D support for ATI RADEON cards?

| Any NEW amigaONE Linux Kernel? : Comment 11 of 55 | ANN.lu |

No need to paraphrase, here's a direct quote from a Hyperion employee
"we won't waste our time fixing the Linux Driver"
Just in case anyone isn't yet familiar with the history in this area....
During Autumn 2002 rumours circulated of problems with the Teron/A1 hardware, and also with the Pegasos, being built on the same Articia S Northbridge. These claims were dismissed by Eyetech and Hyperion who had conducted extensive tests and completely validated the A1 hardware.
In early December 2002 the story was now that the Teron/A1 used a buggy VIA southbridge and the OS4 IDE DMA driver included a suitable workaround for the problem, as did the Linux drivers. There were no problems with the Articia S, and Eyetech had done extensive tests to prove that.
A week or two later, just after Christmas the new story was that early Articia S chips were buggy, and Eyetech knew that it could be fixed in software, but instead they had a hardware fix to tide them over until MAI shipped the next, fixed revision.
Then Eyetech announced that AmigaOne Earlybird hardware would definitely include the hardware fix from MAI, incorporated into the Articia S itself. The problem had been completely eliminated. Reports of problems continued regardless.
In August 2003 the VIA southbridge story was back. A patch to U-Boot and to the Linux Kernel was developed by Hyperion together with MAI which tinkered with the 686B settings, eliminating all problems and proving conclusively that VIA's southbridge had been solely to blame all along.
At the start of November the new patch had completely failed to fix the problem, and a new theory was offered. Now the story became that Hyperion had known all along of a powerful new feature in the Articia S chipset which reduced memory access latency. The Linux drivers don't cater for this feature, but MAI was working on a fix for it. Meanwhile Hyperion had of course written the DMA capable drivers for the AmigaOne (in OS4) properly all along.
Then by December 2003 the story became that no OS4 IDE DMA driver had been written, although one was now in progress. Initial reports said that this driver, like the one written in 2002 was working 100% reliably. The Linux drivers were no longer of interest to Hyperion, and no fixes would be forthcoming from them.
During Spring/summer 2004 an announcement was made that an OS4 IDE DMA driver did now exist, and was 100% reliable, but it couldn't be released for testing and would only be included in the final OS4.0
So basically at any time Eyetech and Hyperion might say nearly anything, but having changed their minds so many times I don't think even they know what the truth is, so it's probably best to steer clear altogether. |
