2018-06-25tw: add light weight timer update functionFlorin Coras1-0/+2
Because it avoids pool putting/getting the timer, this function is somewhat faster than stopping and restarting a timer. Change-Id: Id99ed9d356b0b1f7e12facfe8da193e1cd30b3ec Signed-off-by: Florin Coras <fcoras@cisco.com>
2017-09-01Add fixed-size, preallocated pool supportDave Barach1-1/+23
Simply call pool_init_fixed(...) before using the pool. Note that fixed, preallocated pools live in individually-mmap'ed address segments, except for the free element bitmap. A large fixed pool can exceed 4gb. Fix tcp buffer allocator leak, remove broken assert Change-Id: I4421082e12a77c41c6e20f7747f3150dcd01fc26 Signed-off-by: Dave Barach <dave@barachs.net>

2017-02-16tw_timer_expire_timers() - add a maximum to the number of expiration per callGabriel Ganne1-1/+4
The idea is to prevent a huge processing burst if, say, the network goes down 10' for some reason, and so that we don't need to expire 1M timer sessions on the first call. The maximum is not an exact value, but a value after which the expiration process is postponed until the next call. That way, we don't have to process the same tick twice, nor to unlink timers once at a time when processing a tick. The fact that a timer slot could contain many entries should be dealt with by changing the number of ticks per second.
