Jump out of the kernel

Recommended Posts

I'm thinking it would be useful to have the facility to (optionally) jump out of the kernel.


So eg you might have a construct like this at the end of the kernel



  ifconst .kernel_exit
  jmp .kernel_exit


so you could jump to your minikernel and thence back to where you goto'd drawscreen

(or back to .nevermind if you were so minded)


and free up a couple of stack locations for those tricky text minikernels where you cant find enough pointers

I don't know assembler at all.. but, isn't the answer writing a standard mini kernel that checks for a flag. If the flag is true it jumps to a label set by a variable as a parameter. When the jumped to code section is done it returns to the mini kernel for cleanup and return to the canned main kernel?
