Except for the debugfs, which is intended for testing purposes. Currently we don't allow entering EMLSR from debugfs if EMLSR is blocked, i.e. if mvmvif::esr_disable_reason is not 0. But we need a way to activate EMLSR regardless of the vif being blocked, for testing. Remove the check of esr_disable_reason Signed-off-by: Miri Korenblit Reviewed-by: Johannes Berg --- drivers/net/wireless/intel/iwlwifi/mvm/link.c | 6 +++--- .../net/wireless/intel/iwlwifi/mvm/mld-mac80211.c | 13 ++++--------- drivers/net/wireless/intel/iwlwifi/mvm/mvm.h | 3 +-- 3 files changed, 8 insertions(+), 14 deletions(-) diff --git a/drivers/net/wireless/intel/iwlwifi/mvm/link.c b/drivers/net/wireless/intel/iwlwifi/mvm/link.c index 32ae606a0aa7..1ce52adf3173 100644 --- a/drivers/net/wireless/intel/iwlwifi/mvm/link.c +++ b/drivers/net/wireless/intel/iwlwifi/mvm/link.c @@ -703,9 +703,9 @@ void iwl_mvm_select_links(struct iwl_mvm *mvm, struct ieee80211_vif *vif) primary_link = best_link->link_id; new_active_links = BIT(best_link->link_id); - /* eSR is not supported/allowed, or only one usable link */ - if (max_active_links == 1 || !iwl_mvm_esr_allowed_on_vif(mvm, vif) || - n_data == 1) + /* eSR is not supported/blocked, or only one usable link */ + if (max_active_links == 1 || !iwl_mvm_vif_has_esr_cap(mvm, vif) || + mvmvif->esr_disable_reason || n_data == 1) goto set_active; for (u8 a = 0; a < n_data; a++) diff --git a/drivers/net/wireless/intel/iwlwifi/mvm/mld-mac80211.c b/drivers/net/wireless/intel/iwlwifi/mvm/mld-mac80211.c index e16f1eee8473..5609b0321647 100644 --- a/drivers/net/wireless/intel/iwlwifi/mvm/mld-mac80211.c +++ b/drivers/net/wireless/intel/iwlwifi/mvm/mld-mac80211.c @@ -1159,10 +1159,8 @@ iwl_mvm_mld_change_sta_links(struct ieee80211_hw *hw, return ret; } -bool iwl_mvm_esr_allowed_on_vif(struct iwl_mvm *mvm, - struct ieee80211_vif *vif) +bool iwl_mvm_vif_has_esr_cap(struct iwl_mvm *mvm, struct ieee80211_vif *vif) { - struct iwl_mvm_vif *mvmvif = iwl_mvm_vif_from_mac80211(vif); const struct wiphy_iftype_ext_capab *ext_capa; lockdep_assert_held(&mvm->mutex); @@ -1176,11 +1174,8 @@ bool iwl_mvm_esr_allowed_on_vif(struct iwl_mvm *mvm, ext_capa = cfg80211_get_iftype_ext_capa(mvm->hw->wiphy, ieee80211_vif_type_p2p(vif)); - if (!ext_capa || - !(ext_capa->eml_capabilities & IEEE80211_EML_CAP_EMLSR_SUPP)) - return false; - - return !mvmvif->esr_disable_reason; + return (ext_capa && + (ext_capa->eml_capabilities & IEEE80211_EML_CAP_EMLSR_SUPP)); } static bool iwl_mvm_mld_can_activate_links(struct ieee80211_hw *hw, @@ -1204,7 +1199,7 @@ static bool iwl_mvm_mld_can_activate_links(struct ieee80211_hw *hw, /* If it is an eSR device, check that we can enter eSR */ ret = iwl_mvm_is_esr_supported(mvm->fwrt.trans) && - iwl_mvm_esr_allowed_on_vif(mvm, vif); + iwl_mvm_vif_has_esr_cap(mvm, vif); unlock: mutex_unlock(&mvm->mutex); diff --git a/drivers/net/wireless/intel/iwlwifi/mvm/mvm.h b/drivers/net/wireless/intel/iwlwifi/mvm/mvm.h index fc167ed4578c..c0e0600c4d99 100644 --- a/drivers/net/wireless/intel/iwlwifi/mvm/mvm.h +++ b/drivers/net/wireless/intel/iwlwifi/mvm/mvm.h @@ -2873,8 +2873,7 @@ int iwl_mvm_roc_add_cmd(struct iwl_mvm *mvm, int duration, u32 activity); /* EMLSR */ -bool iwl_mvm_esr_allowed_on_vif(struct iwl_mvm *mvm, - struct ieee80211_vif *vif); +bool iwl_mvm_vif_has_esr_cap(struct iwl_mvm *mvm, struct ieee80211_vif *vif); void iwl_mvm_block_esr(struct iwl_mvm *mvm, struct ieee80211_vif *vif, enum iwl_mvm_esr_state reason, u8 link_to_keep);
