Function Documentation

asmlinkage int exe_schdwk	(	unsigned int *	pidadr,
		void *	prcnam,
		signed long long *	daytim,
		signed long long *	reptim
	)

schedule wakeup - see 5.2 11.6.3

Parameters:

	pidadr	address of pid
	prcnam	process name
	daytim	time of day
	reptim	time to repeat

invoke exe_nampid to find pcb

TODO better handling of sts and vmsunlock

maybe cwps - MISSING

allocate and init tqe

test if one-time or repeating

convert repeat to system time format

if relative clear tqe absolute bit - MISSING

decrement astcnt - MISSING

insert with instimq

return value - MISSING

asmlinkage int exe_setimr	(	unsigned int	efn,
		signed long long *	daytim,
		void(*)(long)	astadr,
		unsigned long	reqidt,
		unsigned int	flags
	)

set timer - see 5.2 11.6.1

Parameters:

	efn	event flag
	daytim	time
	astadr	ast routine
	reqidt	param for it
	flags

test time location - MISSING

test astcnt - MISSING

decrement jib tqcnt, test and maybe MWAIT - MISSING

allocate tqe

clear event flag

fifth nonzero argument test

wrong use TODO use chk_cputim field

if negative, then relative time

set absolute bit - MISSING

store access mode in tqe - MISSING

if no astadr, decrease astcnt and set quota bit - MISSING

insert in timer queue
