Roland Dreier 76d7cc0345 IB/mthca: Use mmiowb() to avoid firmware commands getting jumbled up ... Firmware commands are sent to the HCA by writing multiple words to a command register block. Access to this block of registers is serialized with a mutex. However, on large SGI systems, problems were seen with multiple CPUs issuing FW commands at the same time, because the writes to the register block may be reordered within the system interconnect and reach the HCA in a different order than they were issued (even with the mutex). Fix this by adding an mmiowb() before dropping the mutex. Tested-by: Arthur Kepner <akepner@sgi.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>		2007-10-09 19:59:17 -07:00
