Type: improvement Some tests i.e. ipsec see performance regression when offload flags are moved to 2nd cacheline. This patch moves them back to 1st cacheline. Change-Id: I6ead45ff6d2c467b0d248f409e27c2ba31758741 Signed-off-by: Mohsin Kazmi <sykazmi@cisco.com>

2021-02-15vlib: refactor checksum offload supportMohsin Kazmi1-8/+6
Type: refactor This patch refactors the offload flags in vlib_buffer_t. There are two main reasons behind this refactoring. First, offload flags are insufficient to represent outer and inner headers offloads. Second, room for these flags in first cacheline of vlib_buffer_t is also limited. This patch introduces a generic offload flag in first cacheline. And detailed offload flags in 2nd cacheline of the structure for performance optimization.

2020-12-19avf: fix gcc compiling warning on ArmJieqiang Wang1-4/+4
Initializing struct avf_ip6_psh by {0} using gcc with O2 optimize option will trigger the -Werror=maybe-uninitialized compiling warning on Arm because gcc compiler will think some members of the struct avf_ip6_psh may not be initialized, which probably is a false positive in this case. The compiling error log is shown as below. Avoid this compiling warning by explicitly declaring the IPv6 src and dst ip in avf_ip6_psh as ip6_address_t. ccache /usr/lib/ccache/gcc-10 -DHAVE_FCNTL64 -DHAVE_GETCPU -DHAVE_MEMFD_CREATE -I/home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src -I. -Iinclude -I/home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/plugins -Iplugins -Iplugins/avf -Wno-address-of-packed-member -g -fPIC -Werror -Wall -march=armv8-a+crc -O2 -fstack-protector -DFORTIFY_SOURCE=2 -fno-common -fPIC -DCLIB_MARCH_VARIANT=cortexa72 -march=armv8-a+crc+crypto -mtune=cortex-a72 -DCLIB_N_PREFETCHES=6 -MD -MT plugins/avf/CMakeFiles/avf_plugin_cortexa72.dir/output.c.o -MF plugins/avf/CMakeFiles/avf_plugin_cortexa72.dir/output.c.o.d -o plugins/avf/CMakeFiles/avf_plugin_cortexa72.dir/output.c.o -c /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/plugins/avf/output.c In file included from /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/vppinfra/vector_funcs.h:41, from /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/vppinfra/vector.h:196, from /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/vppinfra/string.h:48, from /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/vppinfra/mem.h:49, from /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/vppinfra/vec.h:42, from /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/vppinfra/format.h:44, from /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/vppinfra/elf.h:41, from /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/vppinfra/elf_clib.h:41, from /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/vlib/vlib.h:44, from /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/plugins/avf/output.c:18: /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/plugins/avf/output.c: In function ‘avf_device_class_tx_fn_cortexa72’: /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/vppinfra/byte_order.h:59:10: error: ‘*((void *)&psh+32)’ may be used uninitialized in this function [-Werror=maybe-uninitialized] 59 | return __builtin_bswap16 (x); | ^~~~~~~~~~~~~~~~~~~~~ /home/snowball/tasks/test_vpp_build/test-patch-9/vpp/src/plugins/avf/output.c:115:23: note: ‘*((void *)&psh+32)’ was declared here 115 | struct avf_ip6_psh psh = { 0 }; | ^~~ Type: fix Change-Id: I2684b101b07823dfacc4a56cc29d152828d0cf37 Signed-off-by: Jieqiang Wang <jieqiang.wang@arm.com>

2020-02-25avf: Handle chain buffer in TX properlySteven Luong1-6/+138
For chain buffer, need to traverse b->next_buffer to transmit all buffers in the chain. Only set EOP at the last descriptor in the chain to signal this is a chain descriptor. Introduce slow path to handle ring wrap. This is needed because chain buffer may consist of multiple pieces and it may span from near the end of the ring to the beginning of the ring.
