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.

/* Function prototypes for the system library. The prototypes in this file

Al's system -> kernel call change
2005-10-14 11:13:52 +02:00
* The system library allows to access system services by doing a kernel call.

2005-07-14 17:12:12 +02:00
* 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.

#ifndef SYSTEM_H
#define SYSTEM_H
/* Common includes for the system library. */
'proc number' is process slot, 'endpoint' are generation-aware process instance numbers, encoded and decoded using macros in <minix/endpoint.h>. proc number -> endpoint migration . proc_nr in the interrupt hook is now an endpoint, proc_nr_e. . m_source for messages and notifies is now an endpoint, instead of proc number. . isokendpt() converts an endpoint to a process number, returns success (but fails if the process number is out of range, the process slot is not a living process, or the given endpoint number does not match the endpoint number in the process slot, indicating an old process). . okendpt() is the same as isokendpt(), but panic()s if the conversion fails. This is mainly used for decoding message.m_source endpoints, and other endpoint numbers in kernel data structures, which should always be correct. . if DEBUG_ENABLE_IPC_WARNINGS is enabled, isokendpt() and okendpt() get passed the __FILE__ and __LINE__ of the calling lines, and print messages about what is wrong with the endpoint number (out of range proc, empty proc, or inconsistent endpoint number), with the caller, making finding where the conversion failed easy without having to include code for every call to print where things went wrong. Sometimes this is harmless (wrong arg to a kernel call), sometimes it's a fatal internal inconsistency (bogus m_source). . some process table fields have been appended an _e to indicate it's become and endpoint. . process endpoint is stored in p_endpoint, without generation number. it turns out the kernel never needs the generation number, except when fork()ing, so it's decoded then. . kernel calls all take endpoints as arguments, not proc numbers. the one exception is sys_fork(), which needs to know in which slot to put the child.

- 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.
