From 5a849e3b359dcf8f730429e1ccb7421f1c4217b6 Mon Sep 17 00:00:00 2001 From: Vladimir Ratnikov Date: Thu, 23 Jul 2020 05:11:09 -0400 Subject: dpdk: device_id sorted order for cryptodev By default, VPP automatically assignes for each tunnel next available QAT device by order dev_id-que-pair. In most cases we have more than one device and it can greatly increase ipsec perfomance without any actions with configuration from user if we use all the devices first and first que-pairs Type: feature Signed-off-by: Vladimir Ratnikov Change-Id: Iac9fe74768775459e22f69bb3706b542090a9375 --- src/plugins/dpdk/cryptodev/cryptodev.c | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) diff --git a/src/plugins/dpdk/cryptodev/cryptodev.c b/src/plugins/dpdk/cryptodev/cryptodev.c index 86cec8a5cbc..2ae09ce226e 100644 --- a/src/plugins/dpdk/cryptodev/cryptodev.c +++ b/src/plugins/dpdk/cryptodev/cryptodev.c @@ -1181,9 +1181,23 @@ cryptodev_create_device (vlib_main_t *vm, u32 n_queues) return 0; } +static int +cryptodev_cmp (void *v1, void *v2) +{ + cryptodev_inst_t *a1 = v1; + cryptodev_inst_t *a2 = v2; + + if (a1->q_id > a2->q_id) + return 1; + if (a1->q_id < a2->q_id) + return -1; + return 0; +} + static int cryptodev_probe (vlib_main_t *vm, u32 n_workers) { + cryptodev_main_t *cmt = &cryptodev_main; u32 n_queues = cryptodev_count_queue (vm->numa_node); u32 i; int ret; @@ -1204,6 +1218,8 @@ cryptodev_probe (vlib_main_t *vm, u32 n_workers) return ret; } + vec_sort_with_function(cmt->cryptodev_inst, cryptodev_cmp); + return 0; } -- cgit 1.2.3-korg
