Reorganized system call library; uses separate file per call now. New configuration header file to include/ exclude functionality. Extracted privileged features from struct proc and create new struct priv. Renamed various system calls for readability.
2005-07-14 17:12:12 +02:00
/* Function prototypes for the system library. The prototypes in this file
* are undefined to do_unused if the kernel call is not enabled in config.h.
* The implementation is contained in src/kernel/system/.
*
* The system library allows to access system services by doing a system call.
* System calls are transformed into request messages to the SYS task that is
* responsible for handling the call. By convention, sys_call() is transformed
* into a message with type SYS_CALL that is handled in a function do_call().
Moved "Changes" comments from system/do_....c to system.h. All changes are now in a single header file.

System processes can be signaled; signals are transformed in SYS_EVENT message that passes signal map along. This mechanisms is also used for nonuser signals like SIGKMESS, SIGKSTOP, SIGKSIG. Revised comments of many system call handlers. Renamed setpriority to nice.

- Fixed comments in various system call handlers. Work in progress on new sys_privctl() call to dynamically start servers and drivers. - Shutdown sequence slightly adjusted: called as watchdog timer to let the busy sys_abort() call from the PM return first. - Changed umap_bios() to have more restrictive check: BIOS memory is now allowed in BIOS_MEM_BEGIN to END (interrupt vectors) and BASE_MEM_TOP to UPPER_MEM_END. Hopefully this keeps QEMU and Bochs happy.
