* iwlwifi: introduce external debug levelMatti Gottlieb2013-08-091-0/+2

* iwlwifi: reduce debug ifdefs using the optimiserJohannes Berg2013-06-131-0/+4
| | | | | | | | | | | Instead of using #ifdef CONFIG_IWLWIFI_DEBUG, remove the iwlwifi_mod_params.debug_level variable completely and make iwl_have_debug_level() always return false in the non-debug case. This way, the optimiser will elide all code for it automatically without having to add #ifdefs.

* iwlwifi: add the MVM driverJohannes Berg2013-02-011-0/+2
| | | | | | | | | | | | | | | | | | | | | Newer firmware revisions have a completely new firmware API. This is the new driver for this new API. I've listed the people who directly contributed code, but many others from various teams have contributed in other ways.

* iwlwifi: refactor EEPROM reading/parsingJohannes Berg2012-06-061-1/+4
| | | | | | | | | | | | | | | | | | | 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.

* iwlwifi: Suppress noisy syslog messages when RF_KILL switch engagedTodd Previte2011-11-111-0/+15
| | | | | | | | | | | | | | | | | | | When a station is associated with an AP and the RF_KILL switch is engaged, numerous error messages were sent to the system log. The error messages were the result of the failure(s) of the various submodules to perform their tasks after the radios were disabled. To resolve this situation, the messages were modified to use a new macro, IWL_DEBUG_QUIET_RFKILL. This macro allows for the RF_KILL error messages to be sent to the log provided that IWL_DEBUG is true and IWL_DL_RADIO is '1'. For all other cases, the error messages resulting from an RFKILL event will not be sent to the system log. Messages logged because of an RFKILL will be tagged with the prefix '(RFKILL)' to clarify the cause of the error.

The device specific struct is allocated together with the common iwl_bus struct by the bus specific layer. The pointer to the aggregate struct is passed to the upper layer that holds a pointer to iwl_bus instead of an embedded iw_bus. The private data given to the PCI subsystem is now iwl_bus and not iwl_priv. Provide bus_* inliners on the way in order to simplify the syntax. Rename iwl-pci.h -> iwl-bus.h since it is bus agnostic and represent the external of the bus layer.

| | | | | | | | | | | | | | | | | | We have seen the throughput dropped due to external noisy environment and the radio is out of tune. There are lot of plcp errors indicating this condition. Eventually the station can get de-authenticated by the Access Point. By resetting and tuning the radio, the plcp errors are reduced or eliminated and the throughput starts to rise. To prevent unexpected behavior such as drop in throughput or deauthentication, - The change provides the driver feature to monitor and tune the radio base on the statistics notification from the uCode. - It also allows the setting of the plcp error rate threshold via the plcp_delta under debugfs interface.

| | | | | | | | | | | | | | | | | | | | | | | Adding "radio reset" function to help reset and stabilize the radio. During normal operation, sometime for unknown reason, radio encounter problem and can not recover by itself; the best way to recover from it is to reset and re-tune the radio. Currently, there is no RF reset command available, but since radio will get reset when switching channel, use internal hw scan request to force radio reset and get back to normal operation state. The internal hw scan will only perform passive scan on the first available channel (not the channel being used) in associated state. The request should be ignored if already performing scan operation or STA is not in associated state. Also include an "internal_scan" debugfs file to help trigger the internal scan from user mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to help uCode debugging, adding the capability to provide continuous uCode event logging function. uCode events is located in round-robin event queue and filled by uCode, by enable continuous event logging, driver check the write pointer and log the newly added events in iwl_bg_ucode_trace() timer function. There is still possibility of missing events if event queue being wrapped before next event dump; but with this capability, we can have much better understanding of the uCode behavior during runtime; it can help to debug the uCode related issues. Methods to enable/disable the continuous event log: step 1: enable ucode trace timer "echo 1 > /sys/kernel/debug/ieee80211/phyX/iwlagn/debug/ucode_tracing" step 2: start ftrace sudo ./trace-cmd record -e iwlwifi_ucode:* sleep 1d step 3: stop ftrace sudo ./trace-cmd report trace.dat step 4: disable ucode trace timer "echo 0 > /sys/kernel/debug/ieee80211/phyX/iwlagn/debug/ucode_tracing" use "ucode_tracing" debugfs file to display number of event queue wrapped when driver attempt the continuous event logging. If event queue being wrapped more than once when driver has opportunity to log the event; it indicated there are events missing in the event log trace. This continuous event log function only available for 4965 and newer NICs.
