Hi, while makeing progress on getting better graphic support for C8000 machines, I'm at a point I need some help... Current status: - PCI Radeon card is passing the DMA tests (using test hack) - fixed three bugs in parisc-agp.c (wrong byte order for iommu entries, missing coherence information in iommu entries and missing fdc for ioemmu entries) - AGP card are still not working, looks like they don't even start a DMA transfer at all I'm stuck at this point as there is no documentation for quicksilver agp available. The zx1-ioa document only covers mercury agp bridges (used and working in ZX2000/ZX6000), but quicksilver is different and I couldn't find the missing bit(s), yet. I now have two ideas to make progess. I'm going to measure, if a REQ signal is issued on the AGP bus and also look if the bridge responds with GNT. The second idea involves HP-UX. I want to look what HP-UX does with quicksilver. Does anyone have a C8000 with a running HP-UX on it and can help getting a register dump of quicksilver ? Otherwise what HP-UX should I try to get for a C8000 ? Thomas. -- Crap can work. Given enough thrust pigs will fly, but it's not necessarily a good idea.
