2012-07-18wlcore: increase command completion timeoutLuciano Coelho
In some rare cases, the CMD_ROC completion may take over 1 second. The timeout had earlier been increased to 1000ms (from 750ms), but it is still not enoug. Increase it to 1500ms. Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-07-18wlcore: wait for command completion event when sending CMD_ROLE_STOPLuciano Coelho
We need to wait for the command completion event when we send the CMD_ROLE_STOP event otherwise we may try to send CMD_ROLE_START too soon and get out-of-sync with the firmware. In some cases, the firmware may not send the event, so we wait for the event or for the timeout, whichever comes first. This patch is based on an earlier version by Eliad.

2012-07-18wlcore: make usage of nla_put clearerYair Shapira
handle errors of nla_put() inside the if(nla_put...) {} This makes the code simpler and clearer because: we take advantage from the fact that we have only one nla_put in our routines (so no real need for goto label). this avoids ugly goto forward followed by goto backward.

2012-07-18wlcore/wl12xx: calibrator fem detect implementationYair Shapira
this completes the calibrator based fem detect logic in driver: driver starts (by calibrator) in plt_mode PLT_FEM_DETECT wlcore inits and starts plt on wl12xx wl12xx fetches fem number from firmware and stores it in wl->fem_manuf wl12xx immediatly returns (doesn't start radio, etc...) wlcore returns the fem_manuf to calibrator using WL1271_TM_ATTR_DATA plt_mode is stopped Signed-off-by: Yair Shapira <yair.shapira@ti.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-07-18wl18xx: disable calibrator based fem detectYair Shapira

2012-07-18wlcore: add plt_mode including new PLT_FEM_DETECTYair Shapira
add wl->plt_mode that is used to indicate different plt working modes: this will be used to implement calibrator side auto fem detection where driver asks firmware to detect the wlan fem radio type and returns it to calibrator. this is not implemented yet and plt_modes: PLT_ON and PLT_FEM_DETECT currently behave the same.

2012-07-18wlcore: use basic rates for non-data packetsEliad Peller
After the latest mac80211 changes, the sta has the ap's sta pointer even before association. This cause the auth and assoc frames to be sent with the standard ap's rates, rather than the basic rates. Change the tx rate policy logic to use the regular ap rates only for data packets (so control and mgmt packets will be sent with basic rates) Signed-off-by: Eliad Peller <eliad@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-07-18wlcore: don't issue SLEEP_AUTH command during recoveryArik Nemtsov

2012-07-18wl18xx: add support for ht_mode in conf.hYair Shapira
ht_mode added to wl18xx conf struct in order to support different modes from the configuration file, as well as module params, and by default (working without a conf file and/or no module params). the hack regarding conf.phy.low_band_component_type for each board is now explicitly handled after parsing module params. missing default values to wl18xx config added. fix string module params not to have defaults (so if empty, param can be taken from conf file). update conf version to 3.

2012-07-18wlcore: don't re-configure wakeup conditions if not neededEyal Shapira
suspend and resume callbacks configure wakeup conditions to the FW which may be different between suspend and resume. This feature is currently not utilized as both in suspend and resume FW wakeup every 1 DTIM. Avoid waking up the chip and doing the FW command unless there's an actual difference in the wakeup conditions.

2012-07-10wlcore: determine AP extra rates correctlyArik Nemtsov
Don't use the ht_mode module parameter for determining AP supported rates. We can rely on channel type, since HT40 won't be enabled if our HT cap doesn't support it. Enable MIMO only if there enough antennas, and rely on per-peer rate limitation to prevent IOPs. Signed-off-by: Arik Nemtsov <arik@wizery.com>
2012-07-10wlcore: check ssid length against the correct elementEliad Peller
commit 587cc28 ("wlcore: compare ssid_len before comparing ssids") introduced a new bug - the ssid length from the request struct was compared against the ssid length of another request, instead the one of the cmd. This might cause the sched scan request to fail (with -EINVAL) in many cases. Signed-off-by: Eliad Peller <eliad@wizery.com>
2012-07-10wl12xx/wl18xx: use a dynamic PS timeout of 1.5secArik Nemtsov
It seems some parties have bad user experience when smaller values are used. This should have little implications for power consumption, since traffic is bursty in nature. Signed-off-by: Arik Nemtsov <arik@wizery.com>
2012-07-10wlcore: define number of supported bands internallyArik Nemtsov
Avoid using the IEEE80211_NUM_BANDS constant for arrays sizes etc, as this can contain bands unsupported by the driver (e.g. 60Ghz). Use an internal constant to determine the number of bands. Signed-off-by: Arik Nemtsov <arik@wizery.com>
2012-07-10wlcore: don't set SDIO_FAILED flag when driver state is offArik Nemtsov
If some IO read/write fails while the FW is not loaded, a recovery will not take place. This means the SDIO_FAILED flag will stay in place forever and prevent further read/writes. This can happen if a check for STATE_OFF was forgotten in some routine. Take this opportunity to rename the flag to IO_FAILED, since we support other buses as well.

2012-07-10wlcore: change the wait for event mechanismYoni Divinsky
wlcore needs to wait for certain events for example for roc complete event. Usually the events are received from the FW very fast, therefore wlcore can poll with a short delay and if after a second the event was not received yet poll with a long (1-5 msec) delay. This implementation is similar to the sending of commands to the FW. Empirically the change reduced the wait for roc event from ~10-40msec to 100s of usecs.

2012-07-10wlcore: Prevent processing of work items during op_stopIdo Yariv
The interrupt line is disabled in op_stop using disable_irq. Since pending interrupts are synchronized, the mutex has to be released before disabling the interrupt to avoid a deadlock with the interrupt handler. In addition, the internal state of the driver is only set to 'off' after the interrupt is disabled. Otherwise, if an interrupt fires after the state is set but before the interrupt line is disabled, the interrupt handler will not be able to acknowledge the interrupt resulting in an interrupt storm. The driver's operations might be called during recovery. If these acquire the mutex after it was released by op_stop, but before the driver's state is changed, they may queue new work items instead of just failing. This is especially problematic in the case of scans, in which a new scan may be scheduled after all scan requests were cancelled.

2012-07-10wl12xx/wlcore: increase FW filename versionLuciano Coelho
We have some API changes and new features in the new firmwares that are not compatible with older drivers. Increase the version of the FW filenames for wl12xx to 5. Additionally, remove the duplicate definitions from wlcore_i.h and remove the MODULE_FIRMWARE macro calls from the SDIO and SPI modules, since they're irrelevant there. Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-07-10wlcore: add probe request templates for sched and one-shot scansYoni Divinsky
The driver configures the firmware template for probe requests during the scan process. If the same template is used for one-shot and sched scans they will override each other when running scans simultaneously. This fix works only on firmwares later than X.3.9.2.112 for single role and X.3.9.2.23 for multi-role.

2012-07-10wlcore: always clear recovery flag during recovery_workArik Nemtsov

2012-07-10wlcore: avoid debug prints during intended FW recoveryArik Nemtsov
Don't read the FW panic log or print other debug data when recovery is intended (i.e. FW type switch). This takes valuable time and can be confusing to the user. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
2012-07-10wlcore: remove recover cmd from testmodeArik Nemtsov

2012-07-10wlcore: enable sched scan while connectedVictor Goldenshtein
New wl12xx firmware supports scheduled scans also while connected. Stop blocking sched scan requests when connected and add a quirk to block in hardware that don't support it (currently wl18xx doesn't).

2012-06-27cfg80211: don't allow WoWLAN support without CONFIG_PMJohannes Berg
When CONFIG_PM is disabled, no device can possibly support WoWLAN since it can't go to sleep to start with. Due to this, mac80211 had even rejected the hardware registration. By making all the code and data for WoWLAN depend on CONFIG_PM we can promote this runtime error to a compile-time error. Add #ifdef around all WoWLAN code to remove it in systems that don't need it as they never suspend.

2012-06-26wlcore: queue recovery in case of bus errors during cmd_remove_peerEyal Shapira
Following the addition of propagating errors from the bus ops there's a need to distinguish between bus errors (including timeout) and a legitimate timeout occuring in cmd_wait_for_event_or_timeout. In case of real bus errors we need to queue recovery even in cases where a timeout on a response from the FW to a command is acceptable.

2012-06-26wlcore: fix broken TX due to wrong queuing of recoveryEyal Shapira
commit 14bba17b "wl12xx: Propagate errors from wl1271_raw_write32" breaks down TX in certain scenarios. wl1271_irq_locked() propagates errors from wl1271_tx_work_locked however it may return -EBUSY when the FW queues are full which is a legitimate case and not a a real error. In this case a recovery is triggered by wl1271_irq and this keeps repeating itself so TX is completely broken. Fix it by avoiding propagating return values as errors even if they aren't. Only bus (SDIO or SPI) ops failures would be progagated as only these should trigger recovery. Signed-off-by: Eyal Shapira <eyal@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
