Excerpts from mail: 24-Oct-98 Re: PCI mapping error by Matthew Jacob@feral.com > >Which platform this is would be helpful. I've been working on an AlphaStation 200 4/233. On the PCI bus are also ncr and de drivers, which are working just fine. To answer one of Mike Smith's questions, va and pa are both set to 0x88000000, I also double checked the mem-map register on the card at one point. I'm going to be grabbing a PC with PCI support later on tonight and see what pops up. Oh, another note. Before I tried out the read/write functions, I tried using direct memory access, this paniced the kernel: manual retype: fatal kernel trap: trap entry = 0x2 (memory management fault) a0 = 88400000 a1 = 0x1 a2 = 0x1 ... If this is a more telling than read/write, I'll do a full register dump and whatever else may help (show map gives another fault, unaligned access) On a note, this card worked under AlphaLinux-XWindows before I got to thinking it should do more than just be an X display.
