I think it works, just needs testing. As soon as pm2fb is running, it'll be safe to declare that 32-bit bus_space is really working. It uses these methods extensively. > BTW, does anybody have a PCMCIA network card which makes the kernel panic? Hmm... does Gayle even allow 32-bit accesses? I always thought that the PCMCIA is 16-bit-only on hardware level. I have ep(4) somewhere, which just doesn't work on amiga for some unknown reason (while it works fine on macppc). There's PR 31134 describing this. Though, that's probably totally unrelated to 32-bit bus_space problems. -- Best regards, Radosław Kujawa

I will also run some tests with it, as soon as you think it is ready. > > BTW, does anybody have a PCMCIA network card which makes the kernel > > panic? > > Hmm... does Gayle even allow 32-bit accesses? I always thought that > the PCMCIA is 16-bit-only on hardware level. Don't know. Maybe the interface is, but the kernel wants to access the registers in 32-bit width nevertheless? I'm no expert here either. I just remember we had some reports about kernel panics with PCMCIA cards in the past, because those 32-bit bus space functions were missing. -- -- Frank Wille
