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.

AT driver is not modified (debugging only); TTY: select and revive with new notify and FS call back; kernel: removed old notify code; removed ugly prepare_shutdown timer kputc: don't send to FS if PRINTF_PROC fails

/* utility.c */
Various fixes and improvements. - fixed bug that caused IDLE to panic (irq hook inconsistency); - kprintf() now accepts multiple arguments; moved to utility.c; - prepare_shutdown() signals system processes with SIGKSTOP; - phys_fill() renamed to phys_memset(), argument order changed; - kmemset() removed in favor of phys_kmemset(); - kstrncpy() removed in favor of phys_copy(); - katoi, kstrncmp replaced by normal library procedure again; - rm_irq_handler() interface changed (simply pass hook pointer);

Miscellaneous clean ups and fixes to the kernel. Support for FLOPPY in boot image. (Set controller=fd at boot monitor.) Moved major device numbers to <minix/dmap.h> (maybe rename to dev.h?)

_PROTOTYPE( int get_priv, (register struct proc *rc, int proc_type) );
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.

_PROTOTYPE( void level0, (void (*func)(void)) );
_PROTOTYPE( void monitor, (void) );
Added args to lock() and unlock() to tell them apart, for use when lock timing is enabled in minix/config.h. Added phys_zero() routine to klib386.s that zeroes a range of memory, and added corresponding system call.
2005-06-01 11:37:52 +02:00
_PROTOTYPE( void read_tsc, (unsigned long *high, unsigned long *low) );
Added function read_cpu_flags() that returns current cpu flags as a long. This is used to check for interrupts being disabled at the time of a lock() call, if enabled in config.h. The number of times this happens is then counted in the kinfo structure. These events (recursive lockings) lead to nasty race conditions.
