If you want to peek at it, see http://publibz.boulder.ibm.com/epubs/pdf/a2278324.pdf . Chapter 6 covers Interruptions. I'd recommend to start with reading external interruptions, because that is the one we'll be primarily be using with kvm. External interruptions are used for things like timers, hypercalls, and IPIs. The "Program Interruption Coditions" are also worth reading, they cover things similar to general protection fault on x86. Chapter 11 covers a different type of Interruptions, such as error detection of hardware failures and hot-standby component failover. Chapter 16 is also of interrest, it covers I/O interruptions.
Whenever you see me in person (next kvm forum maybe?), you are invited to a lot of beer: I'll bring pen and paper and try to give you an overview while we get drunk :-). so long, Carsten ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
