Victor Julien 9f584483be counters: minor cleanups 10 years ago
Victor Julien 8e86f387a6 flow-time: use live threads at shutdown 
Update pktacq loop to process flow timeouts in a running engine.

Add a new step to the shutdown phase of packet acquisition loop
threads (pktacqloop).

The shutdown code lets the pktacqloop break out of it's packet
acquisition loop. The thread then enters a flow timeout loop, where
it processes packets from it's tv->stream_pq queue until it's
empty _and_ the KILL flag is set.

Make sure receive threads are done before moving on to flow hash
cleanup (recycle all). Without this the flow recycler could start
it's unconditional hash clean up while detect threads are still
running on the flows.

Update unix socket to match live modes.

Victor Julien a260cba32b Give easy access for thread stream packet queue 
Access it from ThreadVars. This allows for easy injection of packets
into the stream engine.

Ken Steele 6ebc20f6d8 Rework Tile CPU affinity setting to handle non-contiguous sets of CPUs. 
It is possible to have a non-contiguous CPU set, which was not being
handled correctly on the TILE architecture.

Added a "rank" field in the ThreadVar to store the worker's rank separately
from the cpu for this case.

Ken Steele 592d48aab7 Use Spin locks on Tile 
On Tile, replace pthread_mutex_locks with queued spin locks (ticket
locks) for dataplane processing code. This is safe when running on
dataplane cores with one thread per core. The condition variables are
no-ops when the thread is spinning anyway.

For control plane threads, unix-manager, stats-logs, thread startup,
use pthread_mutex_locks. For these locks replaced SCMutex with SCCtrlMutex
and SCCond with SCCtrlCond.

Ken Steele b08ddfa7f1 Support for Tile Gx atomic instructions 
Tilera's GCC supports the GCC __sync_ intrinsics.

Increase the size of some atomic variables for better performance on
Tile.  The Tile-Gx architecture has native support for 32-bit and
64-bit atomic operations, but not 8-bit and 16-bit, which are emulated
using 32-bit atomics, so changing some 16-bit and 8-bit atomic into
ints improves performance.

Increasing the size of the atomic variables modified in this change
does not increase the total size of the structures in which they
reside because of existing padding requirements. The one case that
would increase the size of the structure (Flow_) was confitionalized
to only change the size on Tile.

Eric Leblond 0809deafc4 Implement function needed for affinity in tm-threads 
This patch features the implementation of affinity related
changes in tm-threads. In place code has been used but some
refactoring has been done to avoid code duplication.
