From 1d1b4c63ba739c6ca695cb2ea13fefa9dfbff60d Mon Sep 17 00:00:00 2001 From: Muhammad Husaini Zulkifli Date: Thu, 15 Dec 2022 00:29:09 +0800 Subject: [PATCH] igc: Remove reset adapter task for i226 during disable tsn config I225 have limitation when programming the BaseTime register which required a power cycle of the controller. This limitation already lifted in I226. This patch removes the restriction so that when user configure/remove any TSN mode, it would not go into power cycle reset adapter. How to test: Schedule any gate control list configuration or delete it. Example: 1) BASE_TIME=$(date +%s%N) tc qdisc replace dev $interface_name parent root handle 100 taprio \ num_tc 4 \ map 3 1 0 2 3 3 3 3 3 3 3 3 3 3 3 3 \ queues 1@0 1@1 1@2 1@3 \ base-time $BASE_TIME \ sched-entry S 0F 1000000 \ flags 0x2 2) tc qdisc del dev $intername_name root Signed-off-by: Muhammad Husaini Zulkifli Tested-by: Naama Meir Signed-off-by: Tony Nguyen --- drivers/net/ethernet/intel/igc/igc_main.c | 6 +++--- drivers/net/ethernet/intel/igc/igc_tsn.c | 11 +++-------- drivers/net/ethernet/intel/igc/igc_tsn.h | 2 +- 3 files changed, 7 insertions(+), 12 deletions(-) diff --git a/drivers/net/ethernet/intel/igc/igc_main.c b/drivers/net/ethernet/intel/igc/igc_main.c index 212560f22254..e86b15efaeb8 100644 --- a/drivers/net/ethernet/intel/igc/igc_main.c +++ b/drivers/net/ethernet/intel/igc/igc_main.c @@ -6020,7 +6020,7 @@ static int igc_tsn_enable_launchtime(struct igc_adapter *adapter, if (err) return err; - return igc_tsn_offload_apply(adapter, qopt->enable); + return igc_tsn_offload_apply(adapter); } static int igc_tsn_clear_schedule(struct igc_adapter *adapter) @@ -6134,7 +6134,7 @@ static int igc_tsn_enable_qbv_scheduling(struct igc_adapter *adapter, if (err) return err; - return igc_tsn_offload_apply(adapter, qopt->enable); + return igc_tsn_offload_apply(adapter); } static int igc_save_cbs_params(struct igc_adapter *adapter, int queue, @@ -6202,7 +6202,7 @@ static int igc_tsn_enable_cbs(struct igc_adapter *adapter, if (err) return err; - return igc_tsn_offload_apply(adapter, qopt->enable); + return igc_tsn_offload_apply(adapter); } static int igc_setup_tc(struct net_device *dev, enum tc_setup_type type, diff --git a/drivers/net/ethernet/intel/igc/igc_tsn.c b/drivers/net/ethernet/intel/igc/igc_tsn.c index d26fc0f47640..a386c8d61dbf 100644 --- a/drivers/net/ethernet/intel/igc/igc_tsn.c +++ b/drivers/net/ethernet/intel/igc/igc_tsn.c @@ -289,21 +289,16 @@ int igc_tsn_reset(struct igc_adapter *adapter) return err; } -int igc_tsn_offload_apply(struct igc_adapter *adapter, bool enable) +int igc_tsn_offload_apply(struct igc_adapter *adapter) { struct igc_hw *hw = &adapter->hw; - int err; - if (netif_running(adapter->netdev) && - (igc_is_device_id_i225(hw) || !enable)) { + if (netif_running(adapter->netdev) && igc_is_device_id_i225(hw)) { schedule_work(&adapter->reset_task); return 0; } - err = igc_tsn_enable_offload(adapter); - if (err < 0) - return err; + igc_tsn_reset(adapter); - adapter->flags = igc_tsn_new_flags(adapter); return 0; } diff --git a/drivers/net/ethernet/intel/igc/igc_tsn.h b/drivers/net/ethernet/intel/igc/igc_tsn.h index 631222bb6eb5..b53e6af560b7 100644 --- a/drivers/net/ethernet/intel/igc/igc_tsn.h +++ b/drivers/net/ethernet/intel/igc/igc_tsn.h @@ -4,7 +4,7 @@ #ifndef _IGC_TSN_H_ #define _IGC_TSN_H_ -int igc_tsn_offload_apply(struct igc_adapter *adapter, bool enable); +int igc_tsn_offload_apply(struct igc_adapter *adapter); int igc_tsn_reset(struct igc_adapter *adapter); void igc_tsn_adjust_txtime_offset(struct igc_adapter *adapter);
