There may *also* be a limit on the number of IOMMU entries. I know some platforms had such limitations. Perhaps you can try reducing from 1000 frames prealloc'd to something smaller -- say 512? Is this a 10GbE driver? If its only 1GbE, then 512 ought to be enough.
Since the original mail shows a SG list length of 16, is there some clue that can be given to the OPL nexus that DVMA/IOMMU space allocation is not needed and the transfers can be done using the real page addresses (or has VM forced a level of abstraction)? _______________________________________________ driver-discuss mailing list driver-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/driver-discuss
