Just 5 kernel stacks - one for every user space thread; This stack is used when a user space thread executes a syscall. In the kernel this is software interrupt context. On x86 systems which do not have the syscall instruction the syscall is executed by moving the arguments in the register and then executing "int 0x80". Do not mix it with SoftIRQ, this is something completly different. > 2. What is the differece btw linux kernel process and kernel thread.

I thought Linux is a monolithic kernel and executes everything in the same address space... -Michi -- programing a layer 3+4 network protocol for mesh networks see http://michaelblizek.homelinux.net -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
