software timer interrupt service routine - see 5.2 11.8
linux leftover or something?
locate process header
test for quantum end and maybe run sch_qend
note that the spinlocks are now inside sch_qend
test if primary cpu
acquire both TIMER and HWCLK spinlocks
iterate
compare system time with 1st time for timer entry
remove first tqe from queue
release both TIMER and HWCLK spinlocks
11.8.1 process timer requests
if TQTYPE CHK_CPUTIM ... - MISSING
test if process still alive - MISSING
if not or if illegal efn, deallocate tqe - MISSING
increment jib tqcnt - MISSING
test jib flags to see if someone waits - MISSING
run sch_chse for each such process - MISSING
test if acb quota in tqe set, user wants ast - MISSING
copy some field to ast - MISSING
call qast
11.8,2 periodic system routine requests TODO check if right
just call it
11.8.3 scheduled wakeup requests
get sched spinlock TODO says who?
test if process still alive - MISSING
if so, and rqpid still exists, increment astcnt - MISSING
if not deallocate tqe - MISSING
call sch_wake to wake it up
if no repeat, do cleanup - MISSING
release sched spinlock TODO says who?
if repeat add tqe delta to tqe time, and do instimq
acquire both TIMER and HWCLK spinlocks

| void exe_timeout | ( | void | ) |
regular system job - see 5.2 11.8.2
do sch_swpwake() if appropiate
passed one second uptime
do erl_wake() if appropiate - MISSING
ecc_reenable() - MISSING
scan i/o db etc for timeous
forklock - MISSING
call device timeout routine to restart i/o if needed
forkunlock - MISSING
scan crbs for more timeouts - MISSING
if running monitor... scan data - MISSING
scan fork and wait queue. soon to be implemented - MISSING
scan lock mgr etc to handle deadlock - MISSING practically
call one_sec
4 sch_ravail() - MISSING
