Start should be 0 for enhanced and 1 for base. Ah. I see now in the IBA 1.2.1 spec, Table 146 PortInfo, p 837, that only an enhanced SP0 supports OperationalVLs. So if a base SP0 doesn't support it, such port also doesn't support VLs, and it makes sense that you shouldn't attempt to program SL2VL maps. Is that what you're thinking? I added this patch on top of above, and things still work w/ no error messages.

* [PATCH v2] opensm/qos.c: Revert port ranges for calls to sl2vl_update_table(). 2010-05-30 23:56 ` Sasha Khapyorsky @ 2010-06-01 14:56 ` Jim Schutt [not found] ` <1275404212-5646-1-git-send-email-jaschut-4OHPYypu0djtX7QSmKvirg@public.gmane.org> 0 siblings, 1 reply; 7+ messages in thread From: Jim Schutt @ 2010-06-01 14:56 UTC (permalink / raw) To: linux-rdma-u79uwXL29TY76Z2rM5mHXA Cc: sashak-smomgflXvOZWk0Htik3J/w, hal.rosenstock-Re5JQEeQqe8AvxtiuMwx3w, Jim Schutt Before commit 051a1dd5 (opensm/osm_qos.c: split switch external and end ports setup), osm_qos_setup() would end up calling sl2vl_update_table() for output ports 1-N, and inport ports 0-N. Commit 051a1dd5 changed this around to be output ports 0-N, and input ports 1-N, and an InfiniScale IV-based fabric would log lots of errors like these: log_rcv_cb_error: ERR 3111: Received MAD with error status = 0x1C SubnGetResp(SLtoVLMappingTable), attr_mod 0x2300, TID 0xad069 Initial path: 0,1,1,4,13 Return path: 0,25,1,7,10 The attr_mod in every such message has 0x00 in the least significant byte, which specifies the output port. With the port ranges restored to their old values, the above log messages stop. Hal Rosenstock pointed out that we should not be attempting to program a base SP0 with SL2VL maps; see, e.g., IBA 1.2.1, section 14.2.5.8, page 844. So, this patch is a full reversion for switches supporting base SP0, but only a partial reversion for switches supporting enhanced SP0.
