Karen> I am interested in Infiniband with x86_64 Opterons. OK, the current code should work well for you -- x86_64 is probably the most-tested architecture. "such platform[s]" in my comment above referred to architectures where arch/xxx/Kconfig does _not_ include drivers/Kconfig; arch/x86_64/Kconfig does include that file. So no change is required to use the current IB patches on x86_64. I believe the only architectures that both support PCI and do not include drivers/Kconfig in their arch Kconfig are arm, sparc, sparc64 and v850. Perhaps I'm wrong, but of those four architectures, sparc64 seems to be the only one where there would be any interest in using IB. - Roland
