2018-09-03Deprecate old buffer replication schemeDamjan Marion1-3/+0
Change-Id: I1f54b994425c58776e1445c8d9fe142e7a644d3d Signed-off-by: Damjan Marion <damarion@cisco.com>
2018-07-18Add config option to use dlmalloc instead of mheapDave Barach1-1/+6
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>
2018-06-03dpdk: improve buffer alloc perfomanceDamjan Marion1-2/+0
This is ~50% improvement in buffer alloc performance. For a 256 buffer allocation, it was ~10 clocks/buffer, now is < 5 clocks. Change-Id: I97590e240a79a42bcab5eb26587fc2d11e6eb163 Signed-off-by: Damjan Marion <damarion@cisco.com>
2018-03-27vlib: make cloned structures cacheline alignedDamjan Marion1-0/+1
This address crash with gcc-7 observed when -o3 is used. Change-Id: I10e87da8e5037ad480eba7fb0aaa9a657d3bf48d Signed-off-by: Damjan Marion <damarion@cisco.com>
2018-03-14vlib: internal buffer manager reworkDamjan Marion1-1/+5
- buffer_main is no longer part of vlib_main_t - pool of free lists is still part of vlib_main_t - mheap is not used anymore for buffer allocation - simple bitmap bassed buffer alloc scheme is introduced Change-Id: I3e1e6d00e2c8122293ed0a741245eb841315a1ff Signed-off-by: Damjan Marion <damarion@cisco.com>
2018-03-05physmem: keep only one physmem_mainDamjan Marion1-2/+0
We don't need per vlib_main physmem_main, so keep it separatelly instead of trying to keep them in sync. Change-Id: I0fbeecf4d9672d31af7a43c640a7d8f05dd6e46f Signed-off-by: Damjan Marion <damarion@cisco.com>
2017-12-15VPP-1102: fix dangling references in RPC handlingDave Barach1-0/+3
Queue RPC calls and send them from the main dispatch loop. As things stood, if the vpp main input queue filled, worker threads could enter a barrier-sync spin-wait in the middle of processing a frame. If thread 0 decided to recreate worker thread data structures, the worker thread(s) could easily crash. Legislate the problem out of existence by enqueueing RPC messages only from the main dispatch loop. At that point, doing a barrier-sync wait is perfectly OK.

2017-10-14VPP-1029: Don't call clib_longjmp(...) directly from the SIGTERM handlerDave Barach1-0/+5
It's way too easy to imagine leaving a mutex or a spin-lock held in the /vpe-api shared-memory segment, or elsewhere. Set a volatile variable and check it in a safe place... Change-Id: I9d91c38cffeb921143c272162d055c9c24a6c312 Signed-off-by: Dave Barach <dave@barachs.net>

2017-09-05Refork worker thread data structures in parallel (VPP-970)Colin Tregenza Dancer1-0/+6
Change the rebuilding of worker thread clone datastructures to run in parallel on the workers, instead of serially on main. Change-Id: Ib76bcfbef1e51f2399972090f4057be7aaa84e08 Signed-off-by: Colin Tregenza Dancer <ctd@metaswitch.com>

2017-04-06Use thread local storage for thread indexDamjan Marion1-1/+1
This patch deprecates stack-based thread identification, Also removes requirement that thread stacks are adjacent. Finally, possibly annoying for some folks, it renames all occurences of cpu_index and cpu_number with thread index. Using word "cpu" is misleading here as thread can be migrated ti different CPU, and also it is not related to linux cpu index.
