<P><FONT SIZE=2>Hi,</FONT>
</P>
<P><FONT SIZE=2>This message indicates that UDAVs for special QPs are located in the DDR memory and not host memory.</FONT>
<BR><FONT SIZE=2>It is a warning since when working with host memory the performance of the MADs is better, however everything will work just fine.</FONT></P>
<P><FONT SIZE=2>So in general you can ignore these messages.</FONT>

<P><FONT SIZE=2>Hello folks,</FONT>
</P>
<P><FONT SIZE=2>I'm sorry if this is kind of off-topic for this list but I suspect that there </FONT>
<BR><FONT SIZE=2>are quite a few people on this list that can answer my rather simple </FONT>
<BR><FONT SIZE=2>question.</FONT>
</P>
<P><FONT SIZE=2>Every time the tavor-driver loads I see these (kinda scary) warnings:</FONT>
</P>
<P><FONT SIZE=2>THH kernel module initialized successfully VAPI(2): thhul_qpm.c[2140]: </FONT>
<BR><FONT SIZE=2>***WARNING***: AVs for special QPs should use HOST memory; the provided PD </FONT>
<BR><FONT SIZE=2>has its AVs in DDR memory.</FONT>
<BR><FONT SIZE=2>(repeated four times)</FONT>
</P>
<P><FONT SIZE=2>Does anybody know what this means (it's not exactly english to me ;). Can it </FONT>
<BR><FONT SIZE=2>be safely ignored? (the systems seems to humm along nicely..)</FONT>
</P>
<P><FONT SIZE=2>I'm running IBGD-1.6.1 from mellanox on my Xeon Nocona cluster (pci-express). </FONT>
<BR><FONT SIZE=2>My HCAs are of the so called "lion cub" type and the os is centos-3.4 </FONT>
