| * | IB/mthca: Fix mthca_write_mtt() on HCAs with hidden memoryRoland Dreier2007-04-251-2/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit b2875d4c ("IB/mthca: Always fill MTTs from CPU") causes a crash in mthca_write_mtt() with non-memfree HCAs that have their memory hidden (that is, have only two PCI BARs instead of having a third BAR that allows access to the RAM attached to the HCA) on 64-bit architectures. This is because the commit just before, c20e20ab ("IB/mthca: Merge MR and FMR space on 64-bit systems") makes dev->mr_table.fmr_mtt_buddy equal to &dev->mr_table.mtt_buddy and hence mthca_write_mtt() tries to write directly into the HCA's MTT table. However, since that table is in the HCA's memory, this is impossible without the PCI BAR that gives access to that memory. This causes a crash because mthca_tavor_write_mtt_seg() basically tries to dereference some offset of a NULL pointer. Fix this by adding a test of MTHCA_FLAG_FMR in mthca_write_mtt() so that we always use the WRITE_MTT firmware command rather than writing directly if FMRs are not enabled.

Previously, one process was nominated as the master and that process was responsible for receiving all packets from the shared hardware port and either consuming them or forwarding them to their destination.

This had a conflict on powerpc. The new scheme converts it to a physical address so it doesn't conflict with chip addresses and yet still fits in 40/44 bits so it isn't truncated by 32-bit applications calling mmap64().
