HELPER FUNCTIONS
|
||||
================
|
||||
|
||||
The slow-work facility provides a function by which it can be determined
|
||||
whether or not an item is queued for later execution:
|
||||
|
||||
bool queued = slow_work_is_queued(struct slow_work *work);
|
||||
|
||||
If it returns false, then the item is not on the queue (it may be executing
|
||||
with a requeue pending). This can be used to work out whether an item on which
|
||||
another depends is on the queue, thus allowing a dependent item to be queued
|
||||
after it.
|
||||
|
||||
If the above shows an item on which another depends not to be queued, then the
|
||||
owner of the dependent item might need to wait. However, to avoid locking up
|
||||
the threads unnecessarily be sleeping in them, it can make sense under some
|
||||
circumstances to return the work item to the queue, thus deferring it until
|
||||
some other items have had a chance to make use of the yielded thread.
|
||||
|
||||
To yield a thread and defer an item, the work function should simply enqueue
|
||||
the work item again and return. However, this doesn't work if there's nothing
|
||||
actually on the queue, as the thread just vacated will jump straight back into
|
||||
the item's work function, thus busy waiting on a CPU.
|
||||
|
||||
Instead, the item should use the thread to wait for the dependency to go away,
|
||||
but rather than using schedule() or schedule_timeout() to sleep, it should use
|
||||
the following function:
|
||||
|
||||
bool requeue = slow_work_sleep_till_thread_needed(
|
||||
struct slow_work *work,
|
||||
signed long *_timeout);
|
||||
|
||||
This will add a second wait and then sleep, such that it will be woken up if
|
||||
either something appears on the queue that could usefully make use of the
|
||||
thread - and behind which this item can be queued, or if the event the caller
|
||||
set up to wait for happens. True will be returned if something else appeared
|
||||
on the queue and this work function should perhaps return, of false if
|
||||
something else woke it up. The timeout is as for schedule_timeout().
|
||||
|
||||
For example:
|
||||
|
||||
wq = bit_waitqueue(&my_flags, MY_BIT);
|
||||
init_wait(&wait);
|
||||
requeue = false;

VIEWING EXECUTING AND QUEUED ITEMS
|
||||
==================================
|
||||
|
||||
If CONFIG_SLOW_WORK_DEBUG is enabled, a debugfs file is made available:
|
||||
|
||||
/sys/kernel/debug/slow_work/runqueue
|
||||
|
||||
through which the list of work items being executed and the queues of items to
|
||||
be executed may be viewed. The owner of a work item is given the chance to
|
||||
add some information of its own.
|
||||
|
||||
The contents look something like the following:
