From a4e4130dcea01f3e0dfcbfeaf0d815b971e6e515 Mon Sep 17 00:00:00 2001 From: Eliad Peller Date: Tue, 11 Oct 2011 11:49:15 +0200 Subject: [PATCH] wl12xx: configure sleep_policy according to active roles If there is an active AP role, stay always on. Otherwise, allow chip to enter elp. (Note that this is a global configuration, so if the device is already configured according to our policy, we don't have to configure it again) Signed-off-by: Eliad Peller Signed-off-by: Luciano Coelho --- drivers/net/wireless/wl12xx/init.c | 29 +++++++++++++++++----------- drivers/net/wireless/wl12xx/main.c | 10 ++++++++++ drivers/net/wireless/wl12xx/wl12xx.h | 2 ++ 3 files changed, 30 insertions(+), 11 deletions(-) diff --git a/drivers/net/wireless/wl12xx/init.c b/drivers/net/wireless/wl12xx/init.c index 80e89e319879..4af7e2fb52fd 100644 --- a/drivers/net/wireless/wl12xx/init.c +++ b/drivers/net/wireless/wl12xx/init.c @@ -343,11 +343,6 @@ static int wl1271_sta_hw_init(struct wl1271 *wl, struct wl12xx_vif *wlvif) if (ret < 0) return ret; - /* Configure for ELP power saving */ - ret = wl1271_acx_sleep_auth(wl, WL1271_PSM_ELP); - if (ret < 0) - return ret; - ret = wl1271_acx_sta_rate_policies(wl, wlvif); if (ret < 0) return ret; @@ -382,11 +377,6 @@ static int wl1271_ap_hw_init(struct wl1271 *wl, struct wl12xx_vif *wlvif) { int ret; - /* Configure for power always on */ - ret = wl1271_acx_sleep_auth(wl, WL1271_PSM_CAM); - if (ret < 0) - return ret; - ret = wl1271_init_ap_rates(wl, wlvif); if (ret < 0) return ret; @@ -577,9 +567,26 @@ int wl1271_init_vif_specific(struct wl1271 *wl, struct ieee80211_vif *vif) struct conf_tx_ac_category *conf_ac; struct conf_tx_tid *conf_tid; bool is_ap = (wlvif->bss_type == BSS_TYPE_AP_BSS); - int ret, i; + /* + * consider all existing roles before configuring psm. + * TODO: reconfigure on interface removal. + */ + if (!wl->ap_count) { + if (is_ap) { + /* Configure for power always on */ + ret = wl1271_acx_sleep_auth(wl, WL1271_PSM_CAM); + if (ret < 0) + return ret; + } else if (!wl->sta_count) { + /* Configure for ELP power saving */ + ret = wl1271_acx_sleep_auth(wl, WL1271_PSM_ELP); + if (ret < 0) + return ret; + } + } + /* Mode specific init */ if (is_ap) { ret = wl1271_ap_hw_init(wl, wlvif); diff --git a/drivers/net/wireless/wl12xx/main.c b/drivers/net/wireless/wl12xx/main.c index 0623f5dc02ca..b52deac368f4 100644 --- a/drivers/net/wireless/wl12xx/main.c +++ b/drivers/net/wireless/wl12xx/main.c @@ -2117,6 +2117,11 @@ static int wl1271_op_add_interface(struct ieee80211_hw *hw, wl->vif = vif; list_add(&wlvif->list, &wl->wlvif_list); set_bit(WL1271_FLAG_IF_INITIALIZED, &wl->flags); + + if (wlvif->bss_type == BSS_TYPE_AP_BSS) + wl->ap_count++; + else + wl->sta_count++; out: mutex_unlock(&wl->mutex); @@ -2188,6 +2193,11 @@ deinit: wlvif->role_id = WL12XX_INVALID_ROLE_ID; wlvif->dev_role_id = WL12XX_INVALID_ROLE_ID; + if (wlvif->bss_type == BSS_TYPE_AP_BSS) + wl->ap_count--; + else + wl->sta_count--; + mutex_unlock(&wl->mutex); cancel_delayed_work_sync(&wlvif->pspoll_work); diff --git a/drivers/net/wireless/wl12xx/wl12xx.h b/drivers/net/wireless/wl12xx/wl12xx.h index 55561c597ad9..fd78f8c1ebcc 100644 --- a/drivers/net/wireless/wl12xx/wl12xx.h +++ b/drivers/net/wireless/wl12xx/wl12xx.h @@ -395,6 +395,8 @@ struct wl1271 { unsigned long roc_map[BITS_TO_LONGS(WL12XX_MAX_ROLES)]; struct list_head wlvif_list; + u8 sta_count; + u8 ap_count; struct wl1271_acx_mem_map *target_mem_map; -- 2.30.2
