Re: IOUserClient Rosetta

It's just an interim test, I'm going native. I 've noticed a previous post that shows endian swapping on an iterator in the application. It's just the shared user/kernel data that needs swapping, right?

I'm pretty impressed by Rosetta. I've got 50 some applications which all seem to work except for the usb driver and 3 apps that talk to it. I thought if I got the kext done, transition would be a leisurely stroll...

Hi Bill,

Is this a Rosetta bug or does the kext need to do something special for Rosetta clients?

If your user client will be opened by PowerPC code running under Rosetta, your user client does need to recognize this and swap unstructured data appropriately.

How to do this isn't publicly documented yet. Please submit a tech support incident with Developer Tech Support and we can help you.

It's important to note that Rosetta is intended as an interim solution while developers are transitioning to universal binaries. As such, DTS would like to understand why a Rosetta-aware user client is truly needed in each case. Please include this information in your email to DTS.

If you're just looking for a way to test your universal driver in the meantime until you've made your app universal, we recommend you just hard-code the necessary endian swapping for the time being. This will be less work than making your user client generally Rosetta-aware.
