gracefully handle crashes of a user mode programm

add kernel events ...

kernel events get triggered by the kernel when certain things happen.
first example: log a message whenever a new programm is loaded from the initrd

add formating print function

make malloc functions accessible to user mode programs

add system call to request memory ...

print hi to vga screen

use string identifiers for events ...

(some rework of the string saving system was required)

use saved strings for service interaction system calls

add discard string system call

add read string syscall

add stringmap insert and read length functions

seperate log into log file and a parallel driver

add events

add a static libary and fix interrupts

enable subscribing to an interrupt and set up the PIC

end tasks when they trigger an exception

add passing data to a syscall

use registers for passing data to system calls

add the ability to create multiple services and repair inter-service communication

add port IO syscalls

clean up syscall code

add basic cross-calling of service providers

organize services and their providers

enter usermode for user processes and start with some memory protection

first steps in services that can be run by the os

add basic kernel page management
