OK, I guess I'm convinced. The vague language in the base PCI 3.0 spec about "dependencies" made me think that a read of a config register had to wait until all previous writes to the same register are done. So I'll drop this patch for now. John, you'll need to try and come up with a way to solve this in the Altix implementation of pci_write_config_xxx(). - R. _______________________________________________ openib-general mailing list [email protected] http://openib.org/mailman/listinfo/openib-general To unsubscribe, please visit http://openib.org/mailman/listinfo/openib-general
