2008-09-11rt2x00: Make rt2x00 LEDS invisible config optionIvo van Doorn1-4/+4
There isn't really a good reason to have the LED configuration options selectable per driver, lets make it default 'y' and make it depend on the NEW_LEDS and LEDS_CLASS interface. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com Signed-off-by: John W. Linville <linville@tuxdriver.com>
2008-09-11rt2x00: Make RFKILL enabled by defaultIvo van Doorn1-4/+4
RFKILL should be enabled for _all_ hardware whether or not they feature a rfkill button or not. Remove driver specific RFKILL configuration options and make the rt2x00lib version depend on CONFIG_RFKILL and defaulting to 'y' to make sure it will always be enabled when RFKILL was enabled. This also fixes some bugs where RFKILL wasn't initialized and didn't respond to RFKILL key presses. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2008-08-30rt2x00: Fix race conditions in flag handlingIvo van Doorn1-1/+1
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.

2008-07-14rt2x00: Reorganize beacon handlingIvo van Doorn1-54/+35
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.

2008-07-14mac80211: revamp beacon configurationJohannes Berg1-1/+1
This patch changes mac80211's beacon configuration handling to never pass skbs to the driver directly but rather always require the driver to use ieee80211_beacon_get(). 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.

2008-07-10rt2x00: Disable synchronization during initializationIvo van Doorn1-0/+11
As soon as init_registers() was called, the rt2400/rt2500 would start raising beacondone interrupts. Since this is highly premature since no beacons were provided yet, we should initialize the synchronization register to 0. This will make all drivers initialize it to 0 regardless if they are raising beacondone interrupts or not, since it only makes sense to have it completely disabled.

With a bit of code moving to rt2x00lib within the TX and RX paths we can now remove a lot of EXPORT_SYMBOL_GPL() statements. This cleans up the interface between rt2x00lib and the drivers and has the additional benefit that rt2x00pci and rt2x00usb are trimmed down in size as well since they have less to do.

2008-06-27rt2x00: Replace statically allocated DMA buffers with mapped skb's.Gertjan van Wingerde1-6/+7
The current PCI drivers require a lot of pre-allocated DMA buffers. Reduce this by using dynamically mapped skb's (using pci_map_single) instead of the pre- allocated DMA buffers that are allocated at device start-up time. At the same time move common RX path code into rt2x00lib from rt2x00pci and rt2x00usb, as the RX paths now are now almost the same.

At the same time clean up the device administration a bit, by storing a pointer to struct device instead of a void pointer that is dependent on the type of device.

2008-06-14rt2x00: Don't kick TX queue after each frameIvo van Doorn1-1/+0
TX queues shouldn't be kicked after each frame that is put into the queue. This could cause problems during RTS and CTS-to-self as well as with fragmentation. In all those cases you want all frames to be send out in a single burst. Off course we shouldn't let the queue fill up entirely, thus we introduce a 10% threshold which, when reached, will force the frames to be send out regardless of the frame. In addition we should prevent queues to become full in such a way that the tx() handler can fail. Instead of stopping the queue when it is full, we should stop it when it is below the threshold.

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.

feature. With the integration of the mac80211 multiqueue patches it has become possible that the mac80211 layer modifies the number of TX queues that is stored inside the ieee80211_hw structure, especially when multi-queue is not selected. The rt2x00 drivers are not well suited to handle that situation, as they allocate the queue structures before mac80211 has modified the number of queues it is going to use, and also expect the number of allocated queues to match the hardware implementation. Hence, ensure that rt2x00 maintains by itself the number of queues that the hardware supports, and, at the same time, making is not dependent on the preservation of contents inside a mac80211 structure.

2008-05-22rt2x00: Fix TX status reportingIvo van Doorn1-1/+12
The tx_status enumeration was broken since the introduction of rt61pci. That driver uses different values to report the status of the tx action. This would lead to frames that were reported as success but actually failed to be send out, or frames that were neither successfull or failure which were reported as failure. Fix this by change the TX status reporting and more explicitely check for failure or success. Note that a third possibility is added "unknown". Not all hardware (USB) can report the actual TX status, for rt61pci some frames will receive this status because the TXdone handler is never called for those frames. This unknown will now be handled as neither success or failure, so we no longer increment the failure counter while this conclusion could not be determined from the real status of the frame.

2008-05-15mac80211: use hardware flags for signal/noise unitsBruno Randolf1-3/+2
trying to clean up the signal/noise code. the previous code in mac80211 had confusing names for the related variables, did not have much definition of what units of signal and noise were provided and used implicit mechanisms from the wireless extensions. this patch introduces hardware capability flags to let the hardware specify clearly if it can provide signal and noise level values and which units it can provide. this also anticipates possible new units like RCPI in the future. for signal: IEEE80211_HW_SIGNAL_UNSPEC - unspecified, unknown, hw specific IEEE80211_HW_SIGNAL_DB - dB difference to unspecified reference point IEEE80211_HW_SIGNAL_DBM - dBm, difference to 1mW for noise we currently only have dBm: IEEE80211_HW_NOISE_DBM - dBm, difference to 1mW if IEEE80211_HW_SIGNAL_UNSPEC or IEEE80211_HW_SIGNAL_DB is used the driver has to provide the maximum value (max_signal) it reports in order for applications to make sense of the signal values. i tried my best to find out for each driver what it can provide and update it but i'm not sure (?) for some of them and used the more conservative guess in doubt. this can be fixed easily after this patch has been merged by changing the hardware flags of the driver.

This makes sense, since when Master mode is active, we should all frames that are send to the active AP (the device itself).

After sampling hundreds of RX frame descriptors, the results were conclusive: - The Ralink documentation regarding the SIGNAL and RSSI are wrong. It turns out that of the 5 BBR registers, we should not use BBR0 and BBR1 for SIGNAL and RSSI respectively, but actually BBR1 and BBR2. BBR0 does show values, but the exact meaning remains unclear, but they cannot be translated into a SIGNAL or RSSI field. BBR3, BBR4 and BBR5 are always 0, so their meaning is unknown. As it turns out, the reported SIGNAL is the PLCP value, this in contradiction to what was expected looking at rt2500pci which only reported the PLCP values for OFDM rates and bitrate values for CCK rates. This means we should let the driver raise the flag about the contents of the SIGNAL field so rt2x00lib can always do the right thing based on what the driver reports.

We should not write 0 to the beacon sync register during config_intf() since that will clear out the beacon interval and forces the beacon to be send out at the lowest interval. (reported by Mattias Nissler). The side effect of the same bug was that while working with multiple virtual AP interfaces a change for any of those interfaces would disable beaconing untill an beacon update was provided. This is resolved by only updating the TSF_SYNC value during config_intf(). In update_beacon() we disable beaconing temporarily to prevent fake beacons to be transmitted.

2008-02-29rt2x00: Make use of MAC80211_LED_TRIGGERSIvo van Doorn1-40/+48
Make use of the led triggers provided by mac80211 to control the led status. This can be enabled through a per-driver configuration option which will automatically enable the generic handler in rt2x00lib. This has been enabled for rt2500usb and rt73usb for the moment since the led class will call set_brightness in irq context which will not work correctly with the usb drivers who need to sleep.

2008-02-29rt2x00: Move beacon and atim queue defines into rt2x00Ivo van Doorn1-5/+48
As Johannes Berg indicated the BEACON and AFTER_BEACON queue indeces in mac80211 should be removed because they are too hardware specific. This patch adds the queue index defines into rt2x00queue.h and removes the dependency of the defines inside mac80211.h. Also move rt2x00pci_beacon_update() into rt2400pci and rt2500pci individually since it is no longer a generic function since rt61 and rt2800 no longer use that.

2008-02-29rt2x00: Add per-interface structureIvo van Doorn1-41/+43
Rework the interface handling. Delete the interface structure and replace it with a per-interface structure. This changes the way rt2x00 handles the active interface drastically. Copy ieee80211_bss_conf to the this rt2x00_intf structure during the bss_info_changed() callback function. This will allow us to reference it later, and removes the requirement for the device flag SHORT_PREAMBLE flag which is interface specific. Drivers receive the option to give the maximum number of virtual interfaces the device can handle. Virtual interface support: rt2400pci: 1 sta or 1 ap, * monitor interfaces rt2500pci: 1 sta or 1 ap, * monitor interfaces rt2500usb: 1 sta or 1 ap, * monitor interfaces rt61pci: 1 sta or 4 ap, * monitor interfaces rt73usb: 1 sta or 4 ap, * monitor interfaces At the moment none of the drivers support AP and STA interfaces simultaneously, this is a hardware limitation so future support will be very unlikely. Each interface structure receives its dedicated beacon entry, with this we can easily work with beaconing while multiple master mode interfaces are currently active. The configuration handlers for the MAC, BSSID and type are often called together since they all belong to the interface configuration. Merge the 3 configuration calls and cleanup the API between rt2x00lib and the drivers. While we are cleaning up the interface configuration anyway, we might as well clean up the configuration handler as well. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.
