- Subject: [ECOS] CYGIMP_KERNEL_SCHED_SORTED_QUEUES flaws.
For reference, here is the description:
cdl_option CYGIMP_KERNEL_SCHED_SORTED_QUEUES {
display "Dequeue oldest threads first"
flavor bool
default_value 0
description "
With this option enabled, threads queued in a thread queue
will be dequeued in priority order, rather than last in,
first out (LIFO). Threads of equal priority are dequeued
oldest first. The only exception is the scheduler run
queues where order is less important as each is already
sorted by priority. Note that this makes the thread queueing
less deterministic."
}
First, it seems that "display" should say something like "Dequeue
highest priority threads first" to be consistent with the description
and the meaning of the option.
Second, the "... rather than last in, first out (LIFO)" seems to be
just wrong. Shouldn't it be "... rather than first in, first out (FIFO)"
instead?
