PCI config is fully working now, USB works too. I'n now running MacOS under mac-on-linux (the new version that doesn't require you to patch the kernel) on linux on the iBook ;) I had to hack horribly in the arch/ppc/kernel/prom.c code that parses the "interrupt-map" property, I'll do a cleaner fix later this week. The PCI code looks good (but I'd prefer using RTAS) and should support bridges on the "middle" bus of uni-north (the one at f2000000 - if you have a better idea to identify this one, tell me !). So PCI should work on G4 and new iMac's too. I didn't fix the ADB interrupt yet (and I'm wondering if my timer is the cause of the large amount of BAD interrupts I'm getting all the time), I'll look into this later too. The kernel seems stable. Things are slow, especially with X, since the hard disk is very slow (1.1Mb/sec). This will be better once I have figured out how to set it to a better PIO mode, use DMA on it, and eventually use this new Ultra/ATA feature (are there specs for this ? Mine are still ATA-3 specs). Have fun ! Benjamin. ** Sent via the linuxppc-dev mail list. See http://lists.linuxppc.org/
