Since sparc64 uses DVMA and if the DVMA address is higher than 1GB it wouldn't work at all." FWIW, I have a Blade 100 running OpenBSD and sound works fine there with OpenBSD's autri(4) driver. I don't see any provisions for dealing with such an address limit in the driver, so I doubt the claim above. -- Christian "naddy" Weisgerber naddy@mips.inka.de
