[ofa-general] synchronize commands issued to MTHCA

[Yicheng Jia]

Hi Folks,

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.

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.

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?

Thanks!
Yicheng
