There are several IOMMU allocator bugs. Instead of trying to fix this overly complicated code, just mirror the PCI IOMMU arena allocator which is very stable and well stress tested. I tried to make the code as identical as possible so we can switch sun4u PCI and SBUS over to a common piece of IOMMU code. All that will be need are two callbacks, one to do a full IOMMU flush and one to do a streaming buffer flush. This patch gets rid of a lot of hangs and mysterious crashes on SBUS sparc64 systems, at least for me. Signed-off-by: David S. Miller <davem@davemloft.net> |
