2012-04-12wireless/wl12xx/wl1251: move TI WLAN modules to a common ti subdirectoryLuciano Coelho1-1203/+0
Move wl12xx and wl1251 modules into a new drivers/net/wireless/ti directory. Add a TI WLAN Kconfig option and Makefile to support this change. Signed-off-by: Luciano Coelho <coelho@ti.com> Cc: John W. Linville <linville@tuxdriver.com>
2012-02-15wl12xx: Use a dedicated fw for PLTEliad Peller1-1/+1
A special PLT firmware is used for calibration. Add multiple fw support by introducing a new fw_type member, representing the currently saved fw (the actual fw state can be determined by wl->state).

2012-02-15wl12xx: consider encryption and QoS in auto arp templateEliad Peller1-0/+1
When configuring the arp response template, and encryption is enabled, we should add some space and set the protected flag bit in the fc. In order to track the encryption type, set wlvif->encryption_type when setting an encryption key, and reconfigure the arp response. Clear this field on wl1271_join, as keys have to be re-configured anyway after a join command. Similarly, track whether QoS is configured.

2012-02-15wl12xx: add forced_ps modeEyal Shapira1-1/+1
For certain WiFi certification tests forcing PS is necessary. Since DPS is now enabled in the FW and this can't be achieved by using netlatency this required a new config option.

Add read/write to suspend_dtim_interval file which controls the number of DTIM periods between wakeups while the host is suspended. The value while the host is resumed is controlled by the file dtim_interval which existed previously.

2012-02-15wl12xx: change WLVIF_FLAG_PSM name and remove WLVIF_FLAG_PSM_REQUESTEDEyal Shapira1-1/+1
WLVIF_FLAG_PSM turned to WLVIF_FLAG_IN_AUTO_PS which marks that this vif is in AUTO PS. WLVIF_FLAG_PSM_REQUESTED is not required as mac80211 calls op_config with CONF_PS after association. wl12xx_config_vif() handling of CONF_PS was simplified and cleaned up.

2011-12-15wl12xx: alloc buffer in driver_state_read to prevent compilation warningLuciano Coelho1-3/+13
When compiling wl12xx for x86, there was a warning complaining about the size of the buffer we were allocating in the stack: drivers/net/wireless/wl12xx/debugfs.c: In function 'driver_state_read': drivers/net/wireless/wl12xx/debugfs.c:380:1: warning: the frame size of 1040 bytes is larger than 1024 bytes To prevent this, allocate the buffer in the heap instead.

2011-10-11wl12xx: move debugging definitions to a separate fileLuciano Coelho1-0/+1
Separate the debugging macros and other definitions to a new debug.h file. This is be needed because the sdio and spi modules don't need to depend on the wl12xx module anymore, but still need to include wl12xx.h. Currently they do depend on it, because of the debugging global that wl12xx exports. A future patch will remove this dependency. Signed-off-by: Luciano Coelho <coelho@ti.com>
2011-10-11wl12xx: replace all remaining wl->vif referencesEliad Peller1-8/+3
wl->vif is appropriate only when a single vif is being used. Instead, pass wlvif as parameter or iterate through all the vifs (e.g. when a global configuration was changed) Leave wl->vif only to determine whether a vif was already added (this check will be removed as well after both the driver and fw will support multiple vifs) Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2011-10-11wl12xx: rearm rx streaming per vifEliad Peller1-2/+8
Currently, the rx streaming doesn't support multi-vif (the actual wlvif is taken from wl->vif, and the management is global). Make the rx streaming timers/works per-vif, and pass the the actual vif as param. Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

Add wlvif->links_map bitmap to represent all the links allocated for this vif. AP vif also has a sta_hlid_map bitmap, which represents the links stations connected to it (sta_hlid_bitmap is a subset of wlvif->links_map, which itself is a subset of the global wl->links_map) Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

2011-07-08wl12xx: start/stop queues according to global per-AC countersArik Nemtsov1-2/+6
Split tx_queue_count to count per-AC skb's queued, instead of relying on the skb-queue len. The skb queues used were only valid in STA-mode, as AP-mode uses per-link queues. This fixes a major regression in AP-mode, caused by the patch "wl12xx: implement Tx watermarks per AC". With that patch applied, we effectively had no regulation of Tx queues in AP-mode. Therefore a sustained high rate of Tx could cause exhaustion of the skb memory pool. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

2011-03-03wl12xx: Switch to a threaded interrupt handlerIdo Yariv1-1/+1
To achieve maximal throughput, it is very important to react to interrupts as soon as possible. Currently the interrupt handler wakes up a worker for handling interrupts in process context. A cleaner and more efficient design would be to request a threaded interrupt handler. This handler's priority is very high, and can do blocking operations such as SDIO/SPI transactions. Some work can be deferred, mostly calls to mac80211 APIs (ieee80211_rx_ni and ieee80211_tx_status). By deferring such work to a different worker, we can keep the irq handler thread more I/O responsive. In addition, on multi-core systems the two threads can be scheduled on different cores, which will improve overall performance. The use of WL1271_FLAG_IRQ_PENDING & WL1271_FLAG_IRQ_RUNNING was changed. For simplicity, always query the FW for more pending interrupts. Since there are relatively long bursts of interrupts, the extra FW status read overhead is negligible. In addition, this enables registering the IRQ handler with the ONESHOT option.
