[OSy] 6th lab topic

[Martin Decky]

Dear all,

> I wanted to ask, if there is any particular topic for the announced 6th
> lab or what parts of source code of Kalisto to review before the lab?

We have reasons to keep the specific topic as a surprise. Suffice to say 
that it won't be a completely new topic, but a reprise of one of the 
previous five topics. The actual task assignment should be relatively easy.

Please see this as a opportunity to refresh your knowledge of all the 
five topics by going through the extended assignments and at least 
mentally realizing what would be necessary to implement them. After all, 
this will be handy for your preparation for the exam, too.

As always, try to focus on the parts of Kalisto that are repeatedly used 
in most assignments -- abstract data structures (such as the linked 
list), concrete data structures (such as the thread structure) and 
commonly used kernel functions (such as the thread manipulating functions).

Also think about the features of C that caused the most trouble 
previously -- working with pointers, array/pointer arithmetics, 
distinguishing between physical/virtual addresses (or frame/page 
indexes, respectively), etc.
