* rt2x00: Add kill_tx_queue callback functionIvo van Doorn2009-02-09
| | | | | | | | | | provide rt2x00lib the possibility to kill a particular TX queue. This can be useful when disabling the radio, but more importantly will allow beaconing to be disabled when mac80211 requests this (during scanning for example) Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

| | | | | | | | | | | | | With mac80211 handling all open interfaces during suspend and resume we can simplify suspend/resume within rt2x00lib. The only thing rt2x00 needs to do is free up memory during suspend and bring back the minimal required components during resume.

* rt2x00: Introduce RXDONE_SIGNAL_MASK maskIvo van Doorn2009-01-29
| | | | | | | | | | | | | Improve error message reporting when a frame was received with unknown rate. Instead of using the boolean check if the frame is supposed to be a PLCP value or not, we should add a new mask (RXDONE_SIGNAL_MASK) which returns the type identification for a signal value (i.e. PLCP). At the moment we only have 2 different types, but more will arrive when support for 11n is added. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

* rt2x00: Fix race condition when using inderect registersIvo van Doorn2008-11-21
| | | | | | | | | | | | | | | | | | | | | Indirect registers require multiple calls to the CSR register in order to access the indirect registers. This must be protected under a lock to prevent race conditions which could cause invalid data to be returned when reading from the indirect register or silent failures when writing data to the indirect register. USB drivers where already protected under a mutex, so rename the mutex and make PCI drivers use the mutex as well. This now means that BBP and RF registers are no longer accessible in interrupt context. That is not a bad situation since the slow behavior of accessing those registers means we don't _want_ to access them in interrupt context either.

* rt2x00: Cleanup TX/RX entry handlingIvo van Doorn2008-11-21
| | | | | | | | | | | | | | | | Merge the callback functions init_txentry() and init_rxentry(). This makes life in rt2x00lib a lot simpler and we can cleanup several functions. rt2x00pci contained "fake" FIELD definitions for descriptor words. This is not flexible since it assumes the driver will always have the same field to indicate if a driver is available or not. This should be dependent on the driver, and we should add a callback function for this. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>
* rt2x00: Fix BUG_ON() with antenna handlingIvo van Doorn2008-11-21
| | | | | | | | | | | | | | | | | | | | | | With the new configuration handling, and more specifically splitting the configuration of the antenna from the normal configuration steps allowed a BUG_ON() to be triggered in the driver because the SW_DIVERSITY was send to the driver. This fixes that by catching the value early in rt2x00config.c and replacing it with a sensible value. This also fixes a problem where the antenna is not being initialized at all when the radio is enabled. Since it no longer is part of the mac80211 configuration the only place where rt2x00 configured it was the SW diversity handler. Obviously this is broken for all non-diversity hardware and breaks SW diversity due to a broken initialization. When the radio is enabled the antenna will be configured once as soon as the config() callback function is called. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

* rt2x00: Only configure hardware when radio is enabledMattias Nissler2008-08-29
| | | | | | | | | | | | | | | | | Some hardware configuration registers such as antenna and channel configuration can only be written when the radio is enabled. Previously, we didn't consider this, so some configuration items could be set inconsistently after reenabling the radio. This patch changes the config() handler to only reprogram the hardware when the radio is enabled. Configuration changes that are made while the radio is off are postponed until the radio is switched back on. We also leave the radio turned off during initialization and only enable it when requested by mac80211. This allows us to get rid of the DIRTY_CONFIG flag, because the device is now guaranteed to be completely initialized when brought up by mac80211.

* rt2x00: Fix race conditions in flag handlingIvo van Doorn2008-08-29
| | | | | | | | | | | | | | | | | | | | | | | Some of the flags should be accessed atomically to prevent race conditions. The flags that are most important are those that can change often and indicate the actual state of the device, queue or queue entry. The big flag rename was done to move all state flags to the same naming type as the other rt2x00dev flags and made sure all places where the flags were used were changed. ;) Thanks to Stephen for most of the queue flags updates, which fixes some of the most obvious consequences of the race conditions. Among those the notorious: rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in the non-full queue 0. rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in the non-full queue 0. rt2x00queue_write_tx_frame: Error - Arrived at non-free entry in the non-full queue 0.

* rt2x00: Implement HW encryptionIvo van Doorn2008-08-22
| | | | | | | | | | | | | | | Various rt2x00 devices support hardware encryption. Most of them require the IV/EIV to be generated by mac80211, but require it to be provided seperately instead of within the frame itself. This means that rt2x00lib should extract the data from the frame and place it in the frame descriptor. During RX the IV/EIV is provided in the descriptor by the hardware which means that it should be inserted into the frame by rt2x00lib.

* rt2x00: Force full register config after start()Ivo van Doorn2008-07-29
| | | | | | | | | | | | | | | | | | | | | rt2x00 will only perform configuration changes from mac80211 when the configuration option has changed. This means it keeps track of the current active configuration and will check these values when the config() callback function is used. However this causes breakage when the interface has been brought down and up again, since all stored active values aren't reset while the registers might have. This is for example the case with rt61pci antenna registers which will jump to invalid values when the interface has been started. To make sure a full configuration takes place after the start() callback function, a new flag is added which will be checked during config() and skips the "what's changed" phase.

Additionally, it introduces "change flags" on the config_interface() call to enable drivers to figure out what is changing. Finally, it removes the beacon_update() driver callback in favour of having IBSS beacon delivered by ieee80211_beacon_get() as well.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This fixes a circular locking dependency in the workqueue handling. The interface work task uses the mac80211 function ieee80211_iterate_active_interfaces() which grabs the RTNL lock. However when the interface is brough down, this happens under the RTNL lock as well, this causes problems because mac80211 will flush the workqueue during the ifdown event. This causes mac80211 to wait until the driver has completed all work which can't finish because it is waiting on the RTNL lock. This is fixed by moving rt2x00 workqueue tasks on a different workqueue, this workqueue can be flushed when the ieee80211_hw structure is removed by the driver (when the driver is unloaded) which does not happen under the RTNL lock.

* | rt2x00: Split rt2x00lib_write_tx_desc()Ivo van Doorn2008-05-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Split rt2x00lib_write_tx_desc() up into a TX descriptor initializor and TX descriptor writer. This split is required to properly allow mac80211 to move its tx_control structure into the skb->cb array. The rt2x00queue_create_tx_descriptor() function will read all tx control information and convert it into a rt2x00 TX descriptor information structure. After that function is complete, we have all information we needed from the tx control structure and are free to start writing into the skb->cb array for our own purposes. rt2x00queue_write_tx_descriptor() will be in charge of really sending the TX descriptor to the hardware and kicking the TX queue.
