This addendum adds prefetch headroom marking processing for s/g segments. We write s/g segments in reverse order into the WQE, in order to guarantee that the first dword of all cachelines containing s/g segments is written last (overwriting the headroom invalidation pattern). The entire cacheline will thus contain valid data when the invalidation pattern is overwritten. } This patch series (1 of 2 is for libmlx4, the same issue). ============================================================ Also, I'm now posting (in a separate post) the following patch to mlx4, which is important: display the following device information via sysfs: board_id, fw_ver, hw_rev, hca_type. The info is displayed under directory /sys/class/infiniband/mlx4_x, where x is the pci bus sequence number (starting from zero). This patch makes information available to ibstat and ibv_devinfo under the same directory as is used for tavor/arbel/sinai -- thus requiring no userspace modifications. - Jack
