Tasks have symbol tables. If symbol not found, parent task's table
|
||||
is searched. Adam task has system-wide symbols.
|
||||
|
||||
SYMBOL LOOK-UP (Especially, used by JIT compiler and Loader)
|
||||
1) Symbol text name is hashed -- Adding the ASCII values of all
|
||||
chars with shifts.
|
||||
2) Hash body array is indexed.
|
||||
3) Linked-list is traversed until match of text and type-of-entry
|
||||
4) If not found, next hash table is searched.
|
||||
|
||||
Duplicate entries are allowed--they overshadow old entries.
|
||||
|
||||
|
||||
ADDRESS-TO-SYMBOL LOOK-UP (Slow because not important--could add tree)
|
||||
1)PSect Cache is scanned.
|
||||
2)"next_added,last_added" que links are traversed. This speeds look-up
|
||||
instead of scanning hash table because hash table is so sparce.
|
||||
|
||||

See $LK,"SparrowOS MultiTasking","FI:::/SparrowOS/Doc/MultiTasking.TXT.Z"$.
|
||||
|
||||
Tasks are ordered in a que based
|
||||
on window front-to-back order with the
|
||||
window mgr as the head, which
|
||||
paints the wallpaper. The scheduler
|
||||
goes in a circle, checking if a task is
|
||||
ready and swapping-it-in if so.
|
||||
Swapping just involves storing and
|
||||
restoring registers -- no disk I/O for
|
||||
virtual memory and no addr map
|
||||
changes. Tasks can be switched in half
|
||||
a microsecond.
|
||||
|
||||
The scheduler checks if a task is
|
||||
waiting for a certain time or waiting
|
||||
on a message and skips it if it's not
|
||||
ready. A task runs until it
|
||||
voluntarily yields ctrl with a call
|
||||
to $LK,"Yield","MN:Yield"$ or gets preempted by the
|
||||
timer interrupt. See $LK,"SYS_TIMER_HANDLER","MN:SYS_TIMER_HANDLER"$.
|
||||
The timer freqency is $LK,"JIFFY_FREQ","MN:JIFFY_FREQ"$. Tasks
|
||||
can ask not to be preempted with
|
||||
$LK,"Preempt","MN:Preempt"$(ON/OFF). Tasks waiting on I/O
|
||||
often loop, checking for a stat and
|
||||
swapping-out. This does not really
|
||||
degrade performance, though it pegs the
|
||||
CPU Load.
|
||||
|
||||
The scheduler checks for a few critical
|
||||
key-strokes such as <CTRL-ALT-X>, which
|
||||
kills a task; <CTRL-ALT-DEL>, which reboots;
|
||||
<CTRL-ALT-T>, which changes focus and <CTRL-ALT-C>,
|
||||
which breaks execution of a program.
|
||||
|
||||
Each core has it's own circular task
|
||||
que. For AP processors, they have a
|
||||
"Seth" task which stays in a loop
|
||||
waiting for jobs or requests to spawn
|
||||
tasks. See $LK,"MPSethServerTask","MN:MPSethServerTask"$().
|
||||
|
||||
All cores have an idle task. If the
|
||||
scheduler determined an IRQ opportunity
|
||||
hasn't happened, the scheduler swaps in
|
||||
the idle task(enabling IRQs).
