Hi,

I'm new to HIPL and studying it. I have some simple questions regarding to 

HIPL kernel code file locations:
1. When I read the "design_choices" document and get to know HIPL is 
implemented using linux kernel module, but i could not find it in HIPL 
source 
code except hipsock. I went through hipsock module briefly, and think it's 
not 
what "design_choices" describes. So the question is where the code is 
located?
2. I noticed that "The kernel modifications for HIP are available in 
vanilla Linux kernel 2.6.27 and above." is mentioned in user mannual. But
I searched my on-hand vanilla kernel (2.6.39) and find no HIP related 
codes. 
Could you help provide some clue? 
3. I checked the hipd module and found it implements HIP state machine in 
user
space process. From document "design_choices", I think this is implemented 
in
kernel. So is there any configuration way to choose user-space or 
kernel-space
implementation?
4. In document "design_choices", one kernel thread khipd is mentioned. But 
I also
could not find anything related with it......

Thanks for your guidance to help me out of struggling in advance!


Thanks,
Lyon
