Task Stack Allocation

April 27, 2009

I made another fairly minor change today. Previously the kernel and user stacks (I’m not quite clear in my mind why we have two stacks, or if the kernel one is ever used – must read the AMD documentation to find out more about this) were being allocated by the tasks themselves. It was just easier, initially, to do things that way. Now I’ve moved the code for this to the task-creation routines. This makes the code cleaner, prevents possible multiple use of the same stack, and makes the tasks themselves easier to write.

The code now is quite a lot cleaner and more logical than that documented on the main site, so I shall make an effort to document it and update things.
