Hello,
Sorry to post to the list without being subscribed, but I've searched the web for information on this and I can't find anything useful. I'm currenty building a realtime visualization system for a Space Shuttle landing simulator at NASA. I'm using a small network of 5 Pentium 4 computers running RedHat's 2.4.20-31.9 kernel. I'm easily running 60 frames/second on my systems, but I'm having a problem because the kscand/Normal thread comes in every 25 seconds and causes me to drop a frame (very annoying). I've looked into the kernel source and found where the kscand threads are spawned. I also see where the 25 second period is coming from. What I'm wondering is what would happen if I disabled the kscand/Normal thread? I've got plenty of memory, and my process is the only thing running on the system. Would I eventually see problems, or would I be OK since I'm not running low on memory? What if I modified the kernel to allow me to temporarily disable the thread while my application is running (using a /proc file or something similar)? Sorry if this is a bad question, but I figure the people on this list are the best source of info.
Please CC: me directly since I'm not subscribed to the list.
Thanks for any help or suggestions, Corbin corbin.l.holtz@jsc.nasa.gov
