* iwlwifi: LED cleanupJohannes Berg2009-10-071-355/+16
| | | | | | | | | | | | | | | | | | | | | | | | | The iwlwifi drivers have LED blinking requirements that mac80211 cannot fulfill due to the use of just a single LED instead of different ones for TX, RX, radio etc. Instead, the single LED blinks according to transfers and is solid on the rest of the time. As such, having LED class devices registered that mac80211 triggers are connected to is pointless as we don't use the triggers anyway. Remove all the useless code and add hooks into the driver itself. At the same time, make the LED code abstracted so the core code that determines blink rate etc. can be shared between 3945 and agn in iwlcore. At the same time, the fact that we removed the use of the mac80211 LED triggers means we can also remove the IWLWIFI_LEDS Kconfig symbol since the LED support is now self-contained.

* iwlwifi: remove command callback return valueJohannes Berg2009-07-271-4/+3
| | | | | | | | | | | | No existing callbacks use anything other than the return value 1, which means that the caller should free the reply skb, so it seems safer in terms of not introducing memory leaks to simply remove the return value and let the caller always free the skb.

* iwlwifi: fix up command sendingJohannes Berg2009-07-271-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | The current command sending in iwlwifi is a bit of a mess: 1) there is a struct, iwl_cmd, that contains both driver and device data in a single packed structure -- this is very confusing 2) the on-stack data and the command metadata share a structure by embedding the latter in the former, which is also rather confusing because it leads to weird unions and similarly odd constructs 3) each txq always has enough space for 256 commands, even if only 32 end up being used This patch fixes these things: 1) rename iwl_cmd to iwl_device_cmd and keep track of command metadata and device command separately, in two arrays in each tx queue 2) remove the 'meta' member from iwl_host_cmd and only put in the required members 3) allocate the cmd/meta arrays separately instead of embedding them into the txq structure Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.

* iwl3945/iwlwifi: fix led bug when SW rfkillAbhijeet Kolekar2009-06-041-4/+0
| | | | | | | | | | | | | | | | | | | | | | | | Patch fixes the bug at http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1903 when SW rfkill is invoked by 'iwconfig txpower off', the existing connection disassociates and led off command is sent to the device which returns error as rfkill is 'true'. Patch fixes this by just avoiding sending the led off/on command when disassociated. The main purpose of the led_disassociate callback is to start or stop the blinking. There are three states in led 1) Always on when radio is on 2) Always off when radio is off 3) blink when associated and if there is some traffic. In this callback 'allow_blinking' needs to be set false when associated, as LED will be always on.

* iwl3945: improve 3945 ledsAbhijeet Kolekar2009-05-221-24/+46
| | | | | | | | | | | | | | | | | 'tpt' is a delta throughput (number of packets) and is corelated to brightness of the LED. We already maintain a delta of packets in rxtxpackets. There is no need to calculate this delta again which was affecting the behaviour of LEDS. Also add two new callback functions for ASSOCIATED/DISASSOCIATED states where LED's will be *on* for associated state and *off* for disassociated state. This fixes http://www.intellinuxwireless.org/bugzilla/show_bug.cgi?id=1771.

| | | | | | | | | | 3945 can now use iwl_led's structure from iwlwifi. Patch also removes CONFIG_IWL3945_LEDS flag from Kconfig as 3945's led support will now be enabled if user selects CONFIG_IWLWIFI_LEDS.

* iwlwifi: another led naming fixDanny Kukawka2009-02-091-4/+4
| | | | | | | | | | | | | Fixed led device naming for the iwlwifi (iwl-3945) driver. Due to the documentation of the led subsystem/class the naming should be "devicename:colour:function" while not applying sections should be left blank. This should lead to e.g. "iwl-%s::RX" instead of "iwl-%s:RX". Signed-off-by: Danny Kukawka <dkukawka@suse.de> Acked-by: Reinette Chatre <reinette.chatre@intel.com> Signed-off-by: John W.

| | | | | | | | | | | With the previously added tfd related ops, we can now use the iwl-tx.c host command enqueue routine. Since the 3945 host command specific routines are identical to the agn ones, we can just remove them from the 3945 code.

* iwlwifi: Don't use buffer allocated on the stack for led namesSven Wegener2008-08-041-16/+17
| | | | | | | | | | | | | | | | | | Having the buffer on the stack and even re-using it for all led devices is bad. Not being able to resolve the name member of the led device structure to a meaningful value leads to confusion during ad-hoc debugging and potential breakage in the future, if we ever decide to access the name member outside of the registration function. Move the buffer to our private per led device structures so that it is accessible after registration. A quick grep didn't yield any occurence of using the led device name parameter outside of the led device registration function, so currently we should already be safe for normal operation.

* iwlwifi: Add led supportMohamed Abbas2008-03-271-0/+433
This patch add LEDS support to 3965 and 4965 drivers. It is based on led trigger and class. For our drivers we needed to avoid two things. 1- We receive led trigger on/off on each Rx\Tx frame. In our driver we can not call led command like that. In this driver once driver receive a start of traffic it call the led command to start blinking then we count all bytes of Tx and Rx frame, after two second we count the blink rate of last two second then id blink rate changed we call the led commands 2- Since we can call led command very often, we make sure we call the led command after we receive the statistics notification so we don't need to wake up the ucode id it is in sleep state. This patch was tested with 4965 and 3945.
