2012-06-06iwlwifi: move DVM code into subdirectoryJohannes Berg1-1148/+0
Since we're working on another mode/driver inside iwlwifi, move the current one into a subdirectory to more cleanly separate the code. While at it, rename all the files. Reviewed-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>
2012-04-23iwlwifi: remove TX/RX frame statisticsJohannes Berg1-1/+0
Keeping statistics per frame type really isn't very useful, and needs a huge amount of code so remove it. Since that is the only thing in iwl-core.{c,h} now, those files can be killed. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>
2012-04-23iwlwifi: clean up iwl-shared.h includesJohannes Berg1-1/+0
That file is now holding just a few defines and the module parameters, so it shouldn't include anything. Make sure the right users include the right files instead. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Wey-Yi Guy <wey-yi.w.guy@intel.com>

2012-04-12iwlwifi: dynamically determine lib_opsJohannes Berg1-4/+4
Having the pointer to lib_ops in the config makes it impossible to split the driver into different modules. Determine the ops based on the device family enumeration to get rid of the direct pointer. Also move all the opmode specific code from the iwl-[1256]000.c files into a new file iwl-agn-devices.c so that the former only have configuration data now.

2012-04-12iwlwifi: move eeprom into privJohannes Berg1-67/+123
The whole code around eeprom is distributed across whole bunch of different files, most of which belong to the to-be-DVM code. As a result, it is currently very hard to split out the EEPROM code to be generic. However, it is also quite unlikely that the current EEPROM code will be needed by the MVM code as that has different mechanisms to query the EEPROM (it does so through the uCode.) So, at least temporarily, move everything into priv. If it becomes necessary to use the code from MVM, we will have to split it out, but then it's also easier since we'll know what pieces we need.

2012-04-12iwlwifi: move hw_params into privJohannes Berg1-12/+12
The hw_params are mostly values that are derived from the actual hardware config. As such, while it is possible that MVM will require similar ones, it makes more sense -- at least for now -- to put them into the DVM struct.

2012-03-06iwlwifi: use valid TX/RX antenna from hw_paramsJohannes Berg1-18/+20
It's not really a good idea to write to the global static configuration. Use the valid TX/RX antenna information only from the HW params struct except in the case where the values from the config are used to override the values from the EEPROM.

2012-03-06iwlwifi: remove SKU from configJohannes Berg1-11/+9
There's no SKU override, we always just use it from EEPROM. As such, we can remove it from the config and use it in hw_param only. Since iwl_eeprom_check_sku() really needs to fill it in also rename that to iwl_eeprom_init_hw_params().

2011-04-29iwlagn: fix tx power initializationStanislaw Gruszka1-7/+0
Since commit f844a709a7d8f8be61a571afc31dfaca9e779621 Author: Stanislaw Gruszka <sgruszka@redhat.com> Date: Fri Jan 28 16:47:44 2011 +0100 iwlwifi: do not set tx power when channel is changing we set device tx power during initialization to priv->tx_power_next, which itself is initialized to minimum power. That changed default behaviour of driver. Previously we initialized device to transmit at maximum available power by default. Patch change again to previous behaviour and cleanup tx power initialization. Fortunately this is not critical fix, as mac80211 layer setup tx power lately to 14dB, hence device does not operate at minimal transmit power all the time.

2011-04-18iwlagn: remove most BUG_ON instancesJohannes Berg1-6/+0
There are a number of things in the driver that may result in a BUG(), which is suboptimal since it's hard to get debugging information out of the driver in that case and the user experience is also not good :-) Almost all BUG_ON instances can be converted to WARN_ON with a few lines of appropriate error handling, so do that instead.

2011-04-07iwlagn: move IO functions out of lineJohannes Berg1-18/+18
This generates a massive reduction in module size: with debug: text data bss dec hex filename 670300 13136 420 683856 a6f50 iwlagn.ko (before) 388347 13136 408 401891 621e3 iwlagn.ko (after) without debug: text data bss dec hex filename 528575 13072 420 542067 84573 iwlagn.ko (before) 294192 13072 408 307672 4b1d8 iwlagn.ko (after) This also removes all the IO debug functionality since it can easily be replaced by tracing, and makes the code unnecessarily complex. I haven't done any CPU utilisation measurements, but given that the hotpaths don't use much IO it is not likely to have a negative impact; in fact, the size reduction will reduce cache pressure which possibly improves performance.
