2019-03-12Use AVX2 as default even on AVX512 systemsDamjan Marion1-1/+1
Use of scalar AVX512 instructions impacts the maximum CPU frequency as they require CPU to request level 1 power license. So sparse use of AVX512 like we do, typically causes more harm than improvement. This patch makes AVX2 higher priority than AVX512, but still there is option to change it on per-node basis: vpp# set node function ethernet-input avx512 Change-Id: I42e03510a6efc1756e22fbb70e8c76d7f74f59d7 Signed-off-by: Damjan Marion <damarion@cisco.com>
2019-02-02Deprecate old mutliarch code, phase 1Damjan Marion1-6/+2
It is causing compilation sloness with gcc-7 so removing it before it was originally planned. So far macros are left in the tree so we can know which nodes to convert to new multiarch code. Change-Id: Idb14622ca61fdce1eba59723b20d98715b7971e6 Signed-off-by: Damjan Marion <damarion@cisco.com>
2019-01-30buffers: major cleanup and improvementsDamjan Marion1-0/+56
This patch introduces following changes: - deprecated free lists which are not used and not compatible with external buffer managers (i.e. DPDK) - introduces native support for per-numa buffer pools - significantly improves performance of buffer alloc and free Change-Id: I4a8e723ae47056717afd6cac0efe87cb731b5be7 Signed-off-by: Damjan Marion <damarion@cisco.com>

2018-10-01Support dynamic dual/quad loop selection on aarch64Lijian Zhang1-0/+90
Currently, there are three variants available on aarch64, qdf24xx, thunderx2t99, and cortex-a72. -DCLIB_N_PREFETCHES is passed to source code to select dual/quad implementation. Besides, different compiler options are applied on these critical functions. gcc-7.3.0 reports ICE(internal compiler error) with -mtune=thunderx2t99, so -mtune=thunderx2t99 is enabled only when gcc version is greater than 7.3.0 Cavium ThunderX2, Impermenter 0x43, Part 0x0af -march=armv8-a+crc+crypto -mtune=thunderx2t99 Qualcomm Centriq 2400, Impermenter 0x51, Part 0xc00 -march=armv8.1-a+crc+crypto -mtune=qdf24xx Cortex-A72, Impermenter 0x41, Part 0xd08 -march=armv8-a+crc+crypto -mtune=cortex-a72 Change-Id: Id5649c6325c1e642d0fd42535e3908793b13e02a Signed-off-by: Lijian Zhang <Lijian.Zhang@arm.com> Reviewed-by: Sirshak Das <sirshak.das@arm.com> Reviewed-by: Honnappa Nagarahalli <Honnappa.Nagarahalli@arm.com>

2017-12-05fill "show cpu" Flag list on aarch64 platforms (VPP-1065)Gabriel Ganne1-4/+65
use getauxval(AT_HWCAP) to get the processor capabilities. The result should be the same as calling cat /proc/cpuinfo | grep Feature | head -n1 All but one (aes) features have a different name. handle aes by adding it an arch prefix, which is skipped during print and a clib_cpu_supports_aes() custom function.
