8 years agomem: introduce memzone freeing

mem: introduce memzone freeing

Implement rte_memzone_free which, as its name implies, would free a
memzone.

Currently memzone are tracked in an array and cannot be free.
To be able to reuse the same array to track memzones, we have to
change how we keep track of reserved memzones.

With this patch, any memzone with addr NULL is not used, so we also need
to change how we look for the next memzone entry free.

Add new unit test for rte_memzone_free API.

mem: rework memzone to be allocated by malloc

In the current memory hierarchy, memsegs are groups of physically
contiguous hugepages, memzones are slices of memsegs and malloc further
slices memzones into smaller memory chunks.

This patch modifies malloc so it partitions memsegs instead of memzones.
Thus memzones would call malloc internally for memory allocation while
maintaining its ABI.

During initialization malloc sets all available memory as part of the heaps.
CONFIG_RTE_MALLOC_MEMZONE_SIZE was used to specify the default memory
block size to expand the heap. The option is not used/relevant anymore,
so we remove it.

Remove free_memseg field from internal mem config structure as it is
not used anymore.
Also remove code in ivshmem that was setting up free_memseg on init.

It would be possible to free memzones and therefore any other structure
based on memzones, ie. mempools

hash: replace with cuckoo hash implementation

This patch replaces the existing hash library with another approach,
using the Cuckoo Hash method to resolve collisions (open addressing),
which pushes items from a full bucket when a new entry tries
to be added in it, storing the evicted entry in an alternative location,
using a secondary hash function.

This gives the user the ability to store more entries when a bucket
is full, in comparison with the previous implementation.
Therefore, the unit test has been updated, as some scenarios have changed
(such as the previous removed restriction).

Also note that the API has not been changed, although new fields
have been added in the rte_hash structure (structure is internal now).
The main change when creating a new table is that the number of entries
per bucket is fixed now, so its parameter is ignored now
(still there to maintain the same parameters structure).
The hash unit test has been updated to reflect these changes.

As a last note, the maximum burst size in lookup_burst function
hash been increased to 64, to improve performance.
