[openib-general] [PATCH][2/12] InfiniBand/mthca: more Arbel Mem-Free support

Roland Dreier roland at topspin.com
Sun Jan 23 22:14:23 PST 2005


Continue development of Arbel Mem-Free support: we now compute a valid
profile, allocate context memory, map sufficient aux memory for HCA
page tables, map sufficient context memory to cover all reserved
firmware resources and successfully call the INIT_HCA and
QUERY_ADAPTER firmware commands.  Fix a few error gotos that unwound
the wrong things.
