2018-10-19vppinfra: add atomic macros for __sync builtinsSirshak Das1-9/+9
This is first part of addition of atomic macros with only macros for __sync builtins. - Based on earlier patch by Damjan (https://gerrit.fd.io/r/#/c/10729/) Additionally - clib_atomic_release macro added and used in the absence of any memory barrier. - clib_atomic_bool_cmp_and_swap added Change-Id: Ie4e48c1e184a652018d1d0d87c4be80ddd180a3b Original-patch-by: Damjan Marion <damarion@cisco.com> Signed-off-by: Sirshak Das <sirshak.das@arm.com> Reviewed-by: Honnappa Nagarahalli <honnappa.nagarahalli@arm.com> Reviewed-by: Ola Liljedahl <ola.liljedahl@arm.com> Reviewed-by: Steve Capper <steve.capper@arm.com>

2018-07-18Add config option to use dlmalloc instead of mheapDave Barach1-0/+4
Configure w/ --enable-dlmalloc, see .../build-data/platforms/vpp.mk src/vppinfra/dlmalloc.[ch] are slightly modified versions of the well-known Doug Lea malloc. Main advantage: dlmalloc mspaces have no inherent size limit. Change-Id: I19b3f43f3c65bcfb82c1a265a97922d01912446e Signed-off-by: Dave Barach <dave@barachs.net>

1) 16-8-8 stride. Reduce trie depth walk traded with increased memory in the top PLY. 2) separate the vector of protocol-independent (PI) fib_table_t with the vector of protocol dependent (PD) FIBs. PD FIBs are large structures, we don't want to burn the memory for ech PD type 3) Go straight to the PD FIB in the data-path thus avoiding an indirection through, e.g., a PLY pool.

2017-03-29Mtrie optimisationsNeale Ranns1-80/+124
1 - make the default route non-special, i.e. like any other less specific route. Consequently, all buckets have a valid valid index of either a leaf or a ply. Checks for special indeices in the data-path can thus be removed. 2 - since all leaves are now 'real' i.e. they represent a real load-balance object, to tell if a ply slot is 'empty' requeirs chekcing that the prefix length of the leaf occupying the slot is slot than the minium value for that ply. 3 - when removing a leaf find the cover first, then recurse down the ply and replace the old leaf with the cover. This saves us a ply walk. Change-Id: Idd523019e8bb1b6ef527b1f5279a5e24bcf18332 Signed-off-by: Neale Ranns <nranns@cisco.com>
