<br><font size=2 face="sans-serif">Hi Folks,</font>
<br>
<br><font size=2 face="sans-serif">I'm using mellanox HCA and I'm a newbie
to this IB community. I'm encountering a problem with the HCA board and
looking forward to getting some help here.</font>
<br>
<br><font size=2 face="sans-serif">I'm using OFED-1.0 and the problem I
believe is related to command synchronization of HCA. The host issues a
MAD_INF command at first and then a SW2HW_MTP command without waiting for
the completion of the first command. Both of commands return with bad parameters
error.</font>
<br>
<br><font size=2 face="sans-serif">My question is why there's no synchronization
mechanism for the command execution on HCA, can I use "spin_lock"
or "sem_wait" to synchronize between every command?</font>
<br>
<br><font size=2 face="sans-serif">Thanks!</font>
