@ -310,3 +310,13 @@ Why: The arch/powerpc tree is the merged architecture for ppc32 and ppc64
Who: linuxppc-dev@ozlabs.org
---------------------------
What: mthca driver's MSI support
When: January 2008
Files: drivers/infiniband/hw/mthca/*.[ch]
Why: All mthca hardware also supports MSI-X, which provides
strictly more functionality than MSI. So there is no point in
having both MSI-X and MSI support in the driver.
