The cache was still full after flushing. In the opposite direction,
i.e. when getting objects from the cache, the cache is refilled to full
level when it crosses the low watermark (which happens to be zero).
Similarly, the cache should be flushed to empty level when it crosses
the high watermark (which happens to be 1.5 x the size of the cache).
The existing flushing behaviour was suboptimal for real applications,
because crossing the low or high watermark typically happens when the
application is in a state where the number of put/get events are out of
balance, e.g. when absorbing a burst of packets into a QoS queue
(getting more mbufs from the mempool), or when a burst of packets is
trickling out from the QoS queue (putting the mbufs back into the
mempool).
Now, the mempool cache is completely flushed when crossing the flush
threshold, so only the newly put (hot) objects remain in the mempool
cache afterwards.
This bug degraded performance caused by too frequent flushing.
Consider this application scenario:
Either, an lcore thread in the application is in a state of balance,
where it uses the mempool cache within its flush/refill boundaries; in
this situation, the flush method is less important, and this fix is
irrelevant.
Or, an lcore thread in the application is out of balance (either
permanently or temporarily), and mostly gets or puts objects from/to the
mempool. If it mostly puts objects, not flushing all of the objects will
cause more frequent flushing. This is the scenario addressed by this
fix. E.g.:
Cache size=256, flushthresh=384 (1.5x size), initial len=256;
application burst len=32.
If there are "size" objects in the cache after flushing, the cache is
flushed at every 4th burst.
If the cache is flushed completely, the cache is only flushed at every
16th burst.
As you can see, this bug caused the cache to be flushed 4x too
frequently in this example.
And when/if the application thread breaks its pattern of continuously
putting objects, and suddenly starts to get objects instead, it will
either get objects already in the cache, or the get() function will
refill the cache.
The concept of not flushing the cache completely was probably based on
an assumption that it is more likely for an application's lcore thread
to get() after flushing than to put() after flushing.
I strongly disagree with this assumption! If an application thread is
continuously putting so much that it overflows the cache, it is much
more likely to keep putting than it is to start getting. If in doubt,
consider how CPU branch predictors work: When the application has done
something many times consecutively, the branch predictor will expect the
application to do the same again, rather than suddenly do something
else.

Fix the rte_mempool_do_generic_put() caching flushing algorithm to
keep hot objects in cache instead of cold ones.
The algorithm was:
1. Add the objects to the cache.
2. Anything greater than the cache size (if it crosses the cache flush
threshold) is flushed to the backend.
Please note that the description in the source code said that it kept
"cache min value" objects after flushing, but the function actually kept
the cache full after flushing, which the above description reflects.
Now, the algorithm is:
1. If the objects cannot be added to the cache without crossing the
flush threshold, flush some cached objects to the backend to
free up required space.
2. Add the objects to the cache.
The most recent (hot) objects were flushed, leaving the oldest (cold)
objects in the mempool cache. The bug degraded performance, because
flushing prevented immediate reuse of the (hot) objects already in
the CPU cache. Now, the existing (cold) objects in the mempool cache
are flushed before the new (hot) objects are added the to the mempool
cache.
Since nearby code is touched anyway fix flush threshold comparison
to do flushing if the threshold is really exceed, not just reached.
I.e. it must be "len > flushthresh", not "len >= flushthresh".
Consider a flush multiplier of 1 instead of 1.5; the cache would be
flushed already when reaching size objects, not when exceeding size
objects. In other words, the cache would not be able to hold "size"
objects, which is clearly a bug. The bug could degraded performance
due to premature flushing.
Since we never exceed flush threshold now, cache size in the mempool
may be decreased from RTE_MEMPOOL_CACHE_MAX_SIZE * 3 to
RTE_MEMPOOL_CACHE_MAX_SIZE * 2. In fact it could be
CALC_CACHE_FLUSHTHRESH(RTE_MEMPOOL_CACHE_MAX_SIZE), but flush
threshold multiplier is internal.

Enabling trace points at runtime was not working if no trace point had
been enabled first at rte_eal_init() time. The reason was that
trace.args reflected the arguments passed to --trace= EAL option.
To fix this:
- the trace subsystem initialisation is updated: trace directory
creation is deferred to when traces are dumped (to avoid creating
directories that may not be used),
- per lcore memory allocation still relies on rte_trace_is_enabled() but
this helper now tracks if any trace point is enabled. The
documentation is updated accordingly,
- cleanup helpers must always be called in rte_eal_cleanup() since some
trace points might have been enabled and disabled in the lifetime of
the DPDK application,
With this fix, we can update the unit test and check that a trace point
callback is invoked when expected.
Note:
- the 'trace' global variable might be shadowed with the argument
passed to the functions dealing with trace point handles.
