This is mainly because when we are resource constrained i.e.\nwhen we have just one online_cpus, we are enabling VMDq and iWARP. It\ndoesn't make sense to enable them with just one cpu and starve kdump\nfor lack of IRQs.\n\nSo don't enable VMDq or iWARP when we just have a single cpu.\n\nSigned-off-by: Avinash Dayanand <avinash.dayanand@intel.com>\n---\n drivers/net/ethernet/intel/i40e/i40e_main.c | 4 ++--\n 1 file changed, 2 insertions(+), 2 deletions(-)", "diff": "diff --git a/drivers/net/ethernet/intel/i40e/i40e_main.c b/drivers/net/ethernet/intel/i40e/i40e_main.c\nindex 3c3cdcd..4493652 100644\n--- a/drivers/net/ethernet/intel/i40e/i40e_main.c\n+++ b/drivers/net/ethernet/intel/i40e/i40e_main.c\n@@ -11115,13 +11115,13 @@ static int i40e_sw_init(struct i40e_pf *pf)\n \t pf->hw.aq.fw_maj_ver >= 6)\n \t\tpf->hw_features |= I40E_HW_PTP_L4_CAPABLE;\n \n-\tif (pf->hw.func_caps.vmdq) {\n+\tif (pf->hw.func_caps.vmdq && num_online_cpus() != 1) {\n \t\tpf->num_vmdq_vsis = I40E_DEFAULT_NUM_VMDQ_VSI;\n \t\tpf->flags |= I40E_FLAG_VMDQ_ENABLED;\n \t\tpf->num_vmdq_qps = i40e_default_queues_per_vmdq(pf);\n \t}\n \n-\tif (pf->hw.func_caps.iwarp) {\n+\tif (pf->hw.func_caps.iwarp && num_online_cpus() != 1) {\n \t\tpf->flags |= I40E_FLAG_IWARP_ENABLED;\n \t\t/* IWARP needs one extra vector for CQP just like MISC.*/\n \t\tpf->num_iwarp_msix = (int)num_online_cpus() + 1;\n", "prefixes": [ "next", "S84-V2", "10/13" ] }
