From 52f993b8e89487ec9ee15a7fb4979e0f09a45b27 Mon Sep 17 00:00:00 2001 From: Yunhong Jiang Date: Wed, 8 Mar 2017 23:13:28 -0800 Subject: Upgrade to 4.4.50-rt62 The current kernel is based on rt kernel v4.4.6-rt14. We will upgrade it to 4.4.50-rt62. The command to achieve it is: a) Clone a git repo from git://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-stable-rt.git b) Get the diff between this two changesets: git diff 640eca2901f3435e616157b11379d3223a44b391 705619beeea1b0b48219a683fd1a901a86fdaf5e where the two commits are: [yjiang5@jnakajim-build linux-stable-rt]$ git show --oneline --name-only 640eca2901f3435e616157b11379d3223a44b391 640eca2901f3 v4.4.6-rt14 localversion-rt [yjiang5@jnakajim-build linux-stable-rt]$ git show --oneline --name-only 705619beeea1b0b48219a683fd1a901a86fdaf5e 705619beeea1 Linux 4.4.50-rt62 localversion-rt c) One patch has been backported thus revert the patch before applying. filterdiff -p1 -x scripts/package/Makefile ~/tmp/v4.4.6-rt14-4.4.50-rt62.diff |patch -p1 --dry-run Upstream status: backport Change-Id: I244d57a32f6066e5a5b9915f9fbf99e7bbca6e01 Signed-off-by: Yunhong Jiang --- kernel/drivers/net/wireless/iwlwifi/mvm/fw.c | 7 +++++-- kernel/drivers/net/wireless/iwlwifi/mvm/mac80211.c | 10 ++++++---- kernel/drivers/net/wireless/iwlwifi/mvm/mvm.h | 3 +++ kernel/drivers/net/wireless/iwlwifi/mvm/sf.c | 2 +- 4 files changed, 15 insertions(+), 7 deletions(-) (limited to 'kernel/drivers/net/wireless/iwlwifi/mvm') diff --git a/kernel/drivers/net/wireless/iwlwifi/mvm/fw.c b/kernel/drivers/net/wireless/iwlwifi/mvm/fw.c index d906fa13b..9584f950f 100644 --- a/kernel/drivers/net/wireless/iwlwifi/mvm/fw.c +++ b/kernel/drivers/net/wireless/iwlwifi/mvm/fw.c @@ -106,7 +106,7 @@ static int iwl_send_tx_ant_cfg(struct iwl_mvm *mvm, u8 valid_tx_ant) sizeof(tx_ant_cmd), &tx_ant_cmd); } -static void iwl_free_fw_paging(struct iwl_mvm *mvm) +void iwl_free_fw_paging(struct iwl_mvm *mvm) { int i; @@ -126,6 +126,8 @@ static void iwl_free_fw_paging(struct iwl_mvm *mvm) get_order(mvm->fw_paging_db[i].fw_paging_size)); } kfree(mvm->trans->paging_download_buf); + mvm->trans->paging_download_buf = NULL; + memset(mvm->fw_paging_db, 0, sizeof(mvm->fw_paging_db)); } @@ -933,7 +935,8 @@ int iwl_mvm_start_fw_dbg_conf(struct iwl_mvm *mvm, u8 conf_id) } mvm->fw_dbg_conf = conf_id; - return ret; + + return 0; } static int iwl_mvm_config_ltr(struct iwl_mvm *mvm) diff --git a/kernel/drivers/net/wireless/iwlwifi/mvm/mac80211.c b/kernel/drivers/net/wireless/iwlwifi/mvm/mac80211.c index e88afac51..ce12717e6 100644 --- a/kernel/drivers/net/wireless/iwlwifi/mvm/mac80211.c +++ b/kernel/drivers/net/wireless/iwlwifi/mvm/mac80211.c @@ -1557,6 +1557,8 @@ void __iwl_mvm_mac_stop(struct iwl_mvm *mvm) /* the fw is stopped, the aux sta is dead: clean up driver state */ iwl_mvm_del_aux_sta(mvm); + iwl_free_fw_paging(mvm); + /* * Clear IN_HW_RESTART flag when stopping the hw (as restart_complete() * won't be called in this case). @@ -3990,8 +3992,8 @@ static int iwl_mvm_mac_get_survey(struct ieee80211_hw *hw, int idx, if (idx != 0) return -ENOENT; - if (fw_has_capa(&mvm->fw->ucode_capa, - IWL_UCODE_TLV_CAPA_RADIO_BEACON_STATS)) + if (!fw_has_capa(&mvm->fw->ucode_capa, + IWL_UCODE_TLV_CAPA_RADIO_BEACON_STATS)) return -ENOENT; mutex_lock(&mvm->mutex); @@ -4037,8 +4039,8 @@ static void iwl_mvm_mac_sta_statistics(struct ieee80211_hw *hw, struct iwl_mvm_vif *mvmvif = iwl_mvm_vif_from_mac80211(vif); struct iwl_mvm_sta *mvmsta = iwl_mvm_sta_from_mac80211(sta); - if (fw_has_capa(&mvm->fw->ucode_capa, - IWL_UCODE_TLV_CAPA_RADIO_BEACON_STATS)) + if (!fw_has_capa(&mvm->fw->ucode_capa, + IWL_UCODE_TLV_CAPA_RADIO_BEACON_STATS)) return; /* if beacon filtering isn't on mac80211 does it anyway */ diff --git a/kernel/drivers/net/wireless/iwlwifi/mvm/mvm.h b/kernel/drivers/net/wireless/iwlwifi/mvm/mvm.h index 4bde2d027..244e26c26 100644 --- a/kernel/drivers/net/wireless/iwlwifi/mvm/mvm.h +++ b/kernel/drivers/net/wireless/iwlwifi/mvm/mvm.h @@ -1190,6 +1190,9 @@ void iwl_mvm_rx_umac_scan_complete_notif(struct iwl_mvm *mvm, void iwl_mvm_rx_umac_scan_iter_complete_notif(struct iwl_mvm *mvm, struct iwl_rx_cmd_buffer *rxb); +/* Paging */ +void iwl_free_fw_paging(struct iwl_mvm *mvm); + /* MVM debugfs */ #ifdef CONFIG_IWLWIFI_DEBUGFS int iwl_mvm_dbgfs_register(struct iwl_mvm *mvm, struct dentry *dbgfs_dir); diff --git a/kernel/drivers/net/wireless/iwlwifi/mvm/sf.c b/kernel/drivers/net/wireless/iwlwifi/mvm/sf.c index b0f59fdd2..d7d72adb6 100644 --- a/kernel/drivers/net/wireless/iwlwifi/mvm/sf.c +++ b/kernel/drivers/net/wireless/iwlwifi/mvm/sf.c @@ -215,7 +215,7 @@ static int iwl_mvm_sf_config(struct iwl_mvm *mvm, u8 sta_id, enum iwl_sf_state new_state) { struct iwl_sf_cfg_cmd sf_cmd = { - .state = cpu_to_le32(SF_FULL_ON), + .state = cpu_to_le32(new_state), }; struct ieee80211_sta *sta; int ret = 0; -- cgit 1.2.3-korg
