* rt2x00: Use GFP_KERNEL for rx buffer allocation on USB devicesHelmut Schaa2012-04-231-1/+1
| | | | | | | | | | | Since the RX path on USB devices is handled in process context we can use GFP_KERNEL for RX buffer allocation. This should reduce the likelihood of allocation failures.

* rt2x00: Don't use queue entry as parameter when creating TX descriptor.Gertjan van Wingerde2011-07-071-1/+2
| | | | | | | | | | | | | | | The functions that create the tx descriptor structure do not operate on a queue entry at all. Signal this fact in the code by not providing a queue entry as a parameter, but the rt2x00 device structure and the skb directly. This patch is a preparation for reducing the time a queue is locked for a tx operation.

| | | | | | | | | | | | | | | The two functions that are in rt2x00ht.c can be much better placed closer to the places where the call-sites of these functions are (one in rt2x00config.c and one in rt2x00queue.c) allowing us to make these functions static. Also, conditional compilations doesn't seem to be necessary anymore as 802.11n support is quite common nowadays. This makes the code a bit easier readable and searchable.

* rt2x00: fix queue timeout checksJohannes Stezenbach2011-04-191-3/+3
| | | | | | | | | | | | | | | Add a timestamp to each queue entry which is updated whenever the status of the entry changes, and remove the per-queue timestamps. The previous check was incorrect and caused both false positives and false negatives. With the corrected check it comes apparent that the TX status usually times out on rt2800usb unless there is sufficient traffic (i.e. the next TX will complete the previous TX status).

* rt2x00: Split rt2x00dev->flagsIvo van Doorn2011-04-191-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | The number of flags defined for the rt2x00dev->flags field, has been growing over the years. Currently we are approaching the maximum number of bits which are available in the field. A secondary problem, is that one part of the field are initialized only during boot, because the driver requirements are initialized or device requirements are loaded from the EEPROM. In both cases, the flags are fixed and will not change during device operation. The other flags are the device state, and will change frequently. So far this resulted in the fact that for some flags, the atomic bit accessors are used, while for the others the non-atomic variants are used. By splitting the flags up into a "flags" and "cap_flags" we can put all flags which are fixed inside "cap_flags". This field can then be read non-atomically. In the "flags" field we keep the device state, which is going to be read atomically. This adds more room for more flags in the future, and sanitizes the field access methods.

* rt2x00: Implement tx power temperature compensationHelmut Schaa2011-04-041-0/+13
| | | | | | | | | | | | | | | | | rt2800 devices should adjust their tx power in accordance with the eeproms temperature calibration values. Add a new driver callback gain_calibration that is called every 4 seconds. The rt2800 gain calibration routine simply runs the tx power configuration that takes care of calculating the temperature compensation delta. We don't need to synchronize the calls to rt2800_config_txpower as they should all happen from mac80211's single threaded workqueue.

| | | | | | | | | | | | | | | | | | | | Since commit d1c3a37ceeb1a5ea02991a0476355f1a1d3b3e83 ("mac80211: clarify alignment docs, fix up alignment") removed the requirement for a 4-byte aligned payload rt2x00queue_align_payload is obsolete as mac80211 will align the payload when it passes the frame to the net stack. As a result we can remove the call to rt2x00queue_align_payload in the rx path and since that's the last user we can remove rt2x00queue_align_payload altogether. One advantage is that we save some alignment operations for frames that don't need to be aligned (for example beause they are not passed to the net stack).

* rt2x00: Refactor beacon code to make use of start- and stop_queueHelmut Schaa2011-01-311-3/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows to dynamically remove beaconing interfaces without shutting beaconing down on all interfaces. The only place to start and stop beaconing are now the start- and stop_queue callbacks. Hence, we can remove some register writes during interface bring up (config_intf) and only write the correct sync mode to the register there. When multiple beaconing interfaces are present we should enable beaconing as soon as mac80211 enables beaconing on at least one of them. The beacon queue gets stopped when the last beaconing interface was stopped by mac80211. Therefore, introduce another interface counter to keep track ot the number of enabled beaconing interfaces and start or stop the beacon queue accordingly. To allow single interfaces to stop beaconing, add a new driver callback clear_beacon to clear a single interface's beacon without affecting the other interfaces. Don't overload the clear_entry callback for clearing beacons as that would introduce additional overhead (check for each TX queue) into the clear_entry callback which is used on the drivers TX/RX hotpaths. Furthermore, the write beacon callback doesn't need to enable beaconing anymore but since beaconing should be disabled while a new beacon is written or cleared we still disable beacon generation and enable it afterwards again in the driver specific callbacks. However, beacon related interrupts should not be disabled/enabled here, that's solely done from the start- and stop queue callbacks. It would be nice to stop the beacon queue just before the beacon update and enable it afterwards in rt2x00queue itself instead of the current implementation that relies on the driver doing the right thing. However, since start- and stop_queue are mutex protected we cannot use them for atomic beacon updates.

This can be simplified by only passing on the queue/entry argument. In cases where rt2x00_dev and a sk_buff are send together, we can send the queue_entry instead. rt2x00usb_alloc_urb and rt2x00usb_free_urb have a bit of vague naming. Instead they allocate all the data which belongs to a rt2x00 data queue entry.

Hence, pass the changed flags to the config_erp driver callback so that the driver can limit the changes to the correct values. This fixes an issue in AP mode where the beacon interval is not initialized (and thus zero) but still sent to the hardware causing an interrupt storm on rt2800pci hanging the system.

| | | | | | | | | | | | | | | | | | | | | | | | Right now all frames mac80211 hands to the driver have the IEEE80211_TX_CTL_REQ_TX_STATUS flag set to request TX status. This isn't really necessary, only the injected frames need TX status (the latter for hostapd) so move setting this flag. The rate control algorithms also need TX status, but they don't require it. Also, rt2x00 uses that bit for its own purposes and seems to require it being set for all frames, but that can be fixed in rt2x00. This doesn't really change anything for any drivers but in the future drivers using hw-rate control may opt to not report TX status for frames that don't have the IEEE80211_TX_CTL_REQ_TX_STATUS flag set.

Additionally there was a bug when inserting L2 padding that only the payload was aligned but not the header. This happens when the header wasn't aligned properly by mac80211, but rt2x00lib only moves the payload. A secondary problem was that when removing L2 padding during TXdone or RX the skb wasn't resized to the proper size. Split the function into seperate functions each handling its task as it should.

| | | | | | | | | | | | | | | | | | | | | | 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: Optimize configuration handlingIvo van Doorn2008-11-101-1/+2
| | | | | | | | | | | | | | | | | | | | | Implement latest changed from mac80211 configuration handling to optmize configuration handling in rt2x00. * Remove set_retry_limit callback function, handled through config() * Move config_antenna to its own callback function, it isn't handled by mac80211 anymore * Use IEEE80211_CONF_CHANGED_* flags and remove manual checks * Removed deprecated short slot setting through config() and put it in config_erp() through which mac80211 now configures it * Remove config_phymode() and move contents to config_erp() since it only managed the basic rates which is now determined by mac80211 through config_erp().

* mac80211: use nl80211 interface typesJohannes Berg2008-09-151-1/+1
| | | | | | | | | | There's really no reason for mac80211 to be using its own interface type defines. Use the nl80211 types and simplify the configuration code a bit: there's no need to translate them any more now. Signed-off-by: Johannes Berg <johannes@sipsolutions.net> Signed-off-by: John W.

* rt2x00: Implement HW encryptionIvo van Doorn2008-08-221-0/+47
| | | | | | | | | | | | | | | 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: Reorganize beacon handlingIvo van Doorn2008-07-141-0/+8
| | | | | | | | | | | | | | With the new beacon handling from mac80211 we can reorganize the beacon handling in rt2x00 as well. This patch will move the function to the TX handlers, and move all duplicate code into rt2x00queue.c. After this change the descriptor helper functions from rt2x00queue.c no longer need to be exported outside of rt2x00lib and can be declared static.
