2014-05-13iwlwifi: dvm: take mutex when sending SYNC BT config commandEmmanuel Grumbach1-2/+6
commit 82e5a649453a3cf23516277abb84273768a1592b upstream. There is a flow in which we send the host command in SYNC mode, but we don't take priv->mutex.

2013-08-12iwlwifi: dvm: don't send BT_CONFIG on devices w/o BluetoothJohannes Berg1-1/+1
commit 707aee401d2467baa785a697f40a6e2d9ee79ad5 upstream. The BT_CONFIG command that is sent to the device during startup will enable BT coex unless the module parameter turns it off, but on devices without Bluetooth this may cause problems, as reported in Redhat BZ 885407. Fix this by sending the BT_CONFIG command only when the device has Bluetooth.

2012-12-07iwlwifi: Change define and struct names in iwl-eeprom-parse.hEytan Lifshitz1-25/+32
Since we will have several forms of NVM (EEPROM, OTP, etc.) and they will have different layouts, make the parsed data more generic. This allows functional code to be independent of a specific layout. Also change some variables and function names from having "eeprom" to "nvm" in their name.

2012-10-31iwlwifi: handle RFKILL logic in the transport layerEmmanuel Grumbach1-2/+0
No HCMD can be sent while RFKILL is asserted. If a SYNC command is running while RFKILL is asserted the fw will silently discard it. This means that the driver needs to wake the process that sleeps on the CMD_SYNC. Since the RFKILL interrupt is handled in the transport layer and the code that sleeps in CMD_SYNC is also in the transport layer, all this logic can be handled there. This simplifies the work of the op_mode. So the transport layer will now return -ERFKILL when a CMD is sent and RFKILL is asserted. This will be the case even when the CMD is SYNC. The transport layer will return -ERFKILL straight away. Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2012-10-16iwlwifi: make data frame tracing optionalJohannes Berg1-0/+3
When tracing in iwlwifi, we get all data. Most of the time, we don't need it, and it just takes up a lot of extra space in the trace. Make this optional by recording the data into two separate trace events if it is needed. Without it, record only the content of non-data and EAPOL TX frames. As a result, tracing without the data tracepoints will record meta information including the 802.11 headers for all frames but will not record the contents of data frames to reduce trace overhead.

It creates a root directory directly in the the root of the debugfs filesystem and within that directories for each device, named after the device ID of the devices iwlwifi is attached to. In the cfg80211/mac80211 directory there's now a link to the toplevel iwlwifi debugfs directory to make it easier to find the debugfs files.

2012-06-06iwlwifi: refactor EEPROM reading/parsingJohannes Berg1-244/+57
The EEPROM reading/parsing code is all mixed in the driver today, and the EEPROM is parsed only when we access data from it. This is problematic because the NVM needs to be parsed and that is independent of reading it. Also, the NVM format for new devices will be different and probably require a new parser. Therefore refactor the reading and parsing and create two independent components. Reading the EEPROM requires direct hardware accesses and therefore access to the transport, but parsing is independent and can be done on an NVM blob.
