Roland Dreier	f3781d2e89	RDMA: Remove subversion $Id tags ... They don't get updated by git and so they're worse than useless. Signed-off-by: Roland Dreier <rolandd@cisco.com>	2008-07-14 23:48:44 -07:00
Sean Hefty	34816ad98e	[IB] Fix MAD layer DMA mappings to avoid touching data buffer once mapped ... The MAD layer was violating the DMA API by touching data buffers used for sends after the DMA mapping was done. This causes problems on non-cache-coherent architectures, because the device doing DMA won't see updates to the payload buffers that exist only in the CPU cache. Fix this by having all MAD consumers use ib_create_send_mad() to allocate their send buffers, and moving the DMA mapping into the MAD layer so it can be done just before calling send (and after any modifications of the send buffer by the MAD layer). Tested on a non-cache-coherent PowerPC 440SPe system. Signed-off-by: Sean Hefty <sean.hefty@intel.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>	2005-10-25 10:51:39 -07:00
