another in an ongoing series of things i'm just throwing together, mostly to document stuff for my own benefit to use later in courseware when i figure out what to do with it. here's a summary i wrote this morning on system calls, which turned out to be longer than i'd planned (it just kind of got away from me): http://www.crashcourse.ca/wiki/index.php/System_calls but a lot of it is just cutting and pasting kernel source for explanatory purposes. feedback welcome. rday -- ======================================================================== Robert P.

Nice article. May be you would like to add below points as well. 1. Some pointers on context switch when system call is invoked. 2. Data transfer between user and kernel mode in brief. 3. Mention of user mode helper calls in kernel. I am not sure what scope you have planned though but I think these points will help. Abhijit

that's all outside the scope of what i was going for, i'm trying to keep these things really brief and focused. later on, i'll go back and piece them together into official courseware. rday -- ======================================================================== Robert P.
