2019-06-25vppinfra: fix tw_timer_first_expires_in_ticks for multiple wheelsAndreas Schultz1-0/+13
When only the fast in wheel is in use, the next expiring has to be within the fast_slot_bitmap. With mutliple wheels, the next expiring timer could be in the slow wheel. The timers on the slow wheel are only moved into the fast wheel when the fast wheel index reaches TW_SLOTS_PER_RING. When calculating the next expiring timer we therefor need to consider the timers on the slow wheel as well. When there are no more before reaching TW_SLOTS_PER_RING, instead of scanning the slow wheel, return the number of ticks until TW_SLOTS_PER_RING is reached.

2018-06-25tw: add light weight timer update functionFlorin Coras1-29/+50
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>
2018-02-20Reset expired timer vector length after callbackDave Barach1-1/+4
Otherwise, in a "catch-up / multiple tick" case, the code will repeatedly hand previously-processed expired timer handles to the user callback. Change-Id: Idef4f242279ea41cb557bb6cff5984de02a6503d Signed-off-by: Dave Barach <dave@barachs.net>

2017-09-01Add fixed-size, preallocated pool supportDave Barach1-6/+110
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>

2017-06-14VPP-874: fix coverity warnings in tw_timer_template.cDave Barach1-4/+4
Best guess, tested carefully, should do no harm. Clang doesn't complain either way; it's not certain that this patch will make the coverity warnings in tw_timer_template.c disappear. Change-Id: I75aa0cfd8970751e823a1165df2a755e947c4cf9 Signed-off-by: Dave Barach <dave@barachs.net>

2017-02-16tw_timer_expire_timers() - add a maximum to the number of expiration per callGabriel Ganne1-2/+6
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.
