Thanks for ther reply! I am still not clear about booting barrelfish on<br>
more than one core. The document<br>
mentioned above only talks about reseting core 0 to boot barrelfish but<br>
doesn't mention anything about<br>
bootscc.sh. The section for booting on subsequent cores (section 2.5)<br>
only talks about telling the CPU driver<br>
to boot other cores but doesn't say how to do that.<br>

The document above is correct, but a little bit too low level. The bootscc.sh script, which is in the tools/scc directory will do all the required booting steps for you (exactly those listed in the tech note).<br>
<br>
Telling the CPU driver to boot other cores works through a commandline argument to spawnd, as explained in my last email. It's the standard process in Barrelfish to boot other cores.<span class="HOEnZb"><font color="#888888"><br>

The bootscc.sh calls another script watchall.sh which is being blocked due to access permissions.</div>
<div>Could you please let me know if watchall.sh is necessary for the installation ? Also I could see the first command in watchall.sh as </div><div>"trap "pkill -P $$" SIGINT" whcih mught be getting blocked. Could you please tell what is it supposed to do ?</div>
<div>I am just wondering if it can be made to execute without requiring root privileges.</div><div> </div><div>Thanks</div><div>Vaibhav Jain</div><div> </div><div><br></div>
