2017-08-30Thread safe internal buffer manager, take twoDamjan Marion1-4/+7
First attempt to make internal buffer manager thread safe was not succesfull, so trying again. This time with more testing. Change-Id: I01b8385a9c26d233934a3339255ea4bd31c865ac Signed-off-by: Damjan Marion <damarion@cisco.com>

2017-07-14Introduce l{2,3,4}_hdr_offset fields in the buffer metadataDamjan Marion1-14/+36
To save space in the first cacheline following is changed: - total_length_not_including_first_buffer moved to the 2nd cacheline. This field is used only when VLIB_BUFFER_TOTAL_LENGTH_VALID and VLIB_BUFFER_NEXT_PRESENT are both set. - free_list_index is now stored in 4bits inside flags, which allows up to 16 free lists. In case we need more we can store index in the 2nd cachelin Change-Id: Ic8521350819391af470d31d3fa1013e67ecb7681 Signed-off-by: Damjan Marion <damarion@cisco.com>
2017-07-13dpdk: fix dpdk_buffer_pool_create nameChris Luke1-3/+0
- vnet_buffer_pool_create should probably be named dpdk_buffer_pool_create since that is what it does. - Its prototype should also be in a DPDK plugin header, not in vlib/buffer_funcs.h, since the implementation is in the plugin and nobody else should be calling it.

2017-07-10vlib: store buffer memory information in the buffer_mainDamjan Marion1-3/+10
Currently, buffer index is calculated as a offset to the physmem region shifted by log2_cacheline size. When DPDK is used we "hack" physmem data with information taken from dpdk mempool. This makes physmem code not usable with DPDK. This change makes buffer memory start and size independent of physmem basically allowing physmem to be used when DPDK plugin is loaded.

2017-04-06Use thread local storage for thread indexDamjan Marion1-2/+2
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.
