These are fixes to sm501 emulation that were found while testing with AmigaOS 4.1FE (AmigaOS 4 is known to work on real hardware but we have no way to verify it against hardware). While this is mainly to improve sam460ex emulation this is now a separate series with the sm501 specific patches because that's also used on SH emulation. I hope someone can review and merge this.

(and add integration tests) AmigaOS 4 is not freely available, it needs to be purchased so I'm not sure it could be used for tests. Also the current version available for Sam460 does not work too well with QEMU yet. To be able to use it according to Sebastian one needs at least updated ehci driver and maybe CLGD graphics driver which are not on this boot CD and editing the CD is not convenient or doable by most people. Therefore we are trying to fix QEMU with Sebastian to be usable with the current boot CD but maybe an updated CD with better drivers would be the way to go, although I don't know if the vendor wants to do that or not. Regards, BALATON Zoltan

OK thanks for the explanation, I plan to add part of it somewhere in the wiki.

I hope > someone can review and merge this. I'm not really familiar with the sm501 hardware, so I can't speak to these technically, beyond the fact that there's nothing obviously bogus. I can say that BALATON Zoltan is the only person who's made non-trivial changes to sm501 lately, and there don't seem to have been any screams, so I'm pretty happy to assume he knows what he's doing. -- David Gibson | I'll have my music baroque, and my code david AT gibson.dropbear.id.au | minimalist, thank you.

Changes all look sane to me even without having sm501 specs at hand. cheers, Gerd
