2008-05-22mac80211: move TX info into skb->cbJohannes Berg1-4/+4
This patch converts mac80211 and all drivers to have transmit information and status in skb->cb rather than allocating extra memory for it and copying all the data around. To make it fit, a union is used where only data that is necessary for all steps is kept outside of the union. A number of fixes were done by Ivo, as well as the rt2x00 part of this patch.

2008-05-22rt2x00: Merge RX and TX entry private dataIvo van Doorn1-3/+3
With the pending removal of the tx_control structure we can merge the RX and TX entry private data structure in advance.

2008-05-22rt2x00: Remove redundant flags/dev_flags initializationsIvo van Doorn1-2/+0
the rxdesc structure is properly memsetted before passed to the driver. This means we don't have to reinitialize the flags and dev_flags fields in the drivers again. This will prevent problems when the rxdone handler is adding flags in a earlier status and will make the code look nicer when we are adding more read attributes in the rxdone handler in the driver.

2008-05-22rt2x00: Split rt2x00lib_write_tx_desc()Ivo van Doorn1-1/+10
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.

2008-05-22rt2x00: Preserve descriptor information after memmove()Ivo van Doorn1-15/+11
Due to usage of memmove() in rt2x00usb the descriptor can become corrupted because it is being overwritten by the data part. Overall having the descriptor in front of the frame is a bad idea, we can however use the skb->cb array for this task, since that contains more then enough room to hold the entire descriptor and preserve the information long enough. After this we can also cleanup the alignment code a bit to make it work a bit more flexible to allow for all kinds of odd header lengths.

2008-05-22rt2x00: Fix queue related oops in case of deselected mac80211 multi-queue ↵Gertjan van Wingerde1-1/+1
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.

2008-05-15mac80211: 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 replaces the method of using the mac80211 trigger events which do not work for USB drivers due to the scheduling requirement. After this patch RT2500USB_LEDS and RT73USB_LEDS no longer need to be tagged as broken since they now support LED handling again without having to check for in_atomic().

2008-04-02rt2x00: TO_DS filter depends on intf_ap_countIvo van Doorn1-1/+2
The TO_DS filter does not only depend on the FIF_PROMISC_IN_BSS flag provided by mac80211, but also on the intf_ap_count count. This makes sense, since when Master mode is active, we should all frames that are send to the active AP (the device itself). This means that when an interface is added we should force the packet filter to be updated during the next mac80211 call of configure_filter() to make sure the intf_ap_count field is checked.

rt73usb and rt2500usb used in_atomic to determine if a configuration step should be rescheduled or not. Since in_atomic() is not a valid method to determine if sleeping is allowed we should fix the way this is handled by adding a new flag to rt2x00. In addition mark LED class support for the drivers broken since that also uses the broken in_atomic() method but so far no solution exists to have LED triggers work only in scheduled context.

2008-03-14rt2x00: Fix rt2400pci signalIvo van Doorn1-1/+5
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.

2008-03-13rt2x00: Move firmware checksumming to driverIvo van Doorn1-5/+23
rt2x00lib depended on 2 crc algorithms because rt61/rt73 use a different algorithm then rt2800. This means that even when only 1 algorithm was needed, the dependency was still present for both. By moving the checksum generation to the driver we can clean up 2 annoying flags (which indicated which checksum was required) and move the dependency to where it belongs: the driver.

2008-03-13rt2x00: Only disable beaconing just before beacon updateIvo van Doorn1-5/+13
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. Finally kick_tx_queue() will enable beaconing again. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W. Linville <linville@tuxdriver.com>

2008-03-13rt2x00: Align RX descriptor to 4 bytesIvo van Doorn1-22/+17
Some architectures give problems when reading RX frame descriptor words when the descriptor is not aligned on a 4 byte boundrary. Due to optimalizations for the ieee80211 payload 4 byte alignment, it is no longer guarenteed that the descriptor is placed on the 4 byte boundrary (In fact, for rt73usb it is absolutely never aligned to 4 bytes, for rt2500usb it depends on the length of the payload). This will copy the descriptor to a 4 byte aligned location before it is read for the first time. This will also move the payload data alignment in rt2x00usb (instead of inside the driver) where it has always belonged. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2008-02-29cfg80211 API for channels/bitrates, mac80211 and driver conversionJohannes Berg1-11/+12
This patch creates new cfg80211 wiphy API for channel and bitrate registration and converts mac80211 and drivers to the new API. The old mac80211 API is completely ripped out. All drivers (except ath5k) are updated to the new API, in many cases I expect that optimisations can be done. Along with the regulatory code I've also ripped out the IEEE80211_HW_DEFAULT_REG_DOMAIN_CONFIGURED flag, I believe it to be unnecessary if the hardware simply gives us whatever channels it wants to support and we then enable/disable them as required, which is pretty much required for travelling. Additionally, the patch adds proper "basic" rate handling for STA mode interface, AP mode interface will have to have new API added to allow userspace to set the basic rate set, currently it'll be empty... However, the basic rate handling will need to be moved to the BSS conf stuff. I do expect there to be bugs in this, especially wrt. transmit power handling where I'm basically clueless about how it should work.

2008-02-29rt2x00: Add per-interface structureIvo van Doorn1-81/+98
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.

2008-02-29rt2x00: Queue handling overhaulIvo van Doorn1-46/+88
This introduces a big queue handling overhaul, this also renames "ring" to "queues". Move queue handling into rt2x00queue.c and the matching header, use Kerneldoc to improve rt2x00 library documentation. Access to the queues is now protected under a spinlock, this to prevent race conditions which could corrupt the indexing system of the queue. Each queue entry allocates x bytes for driver/device specific data, this cleans up the queue structure significantly and improves code readability. rt2500usb no longer needs 2 entries in the beacon queue to correctly send out the guardian byte. This is now handled in the entry specific structure. rt61 and rt73 now use the correct descriptor size for beacon frames, since this data is written into the registers not the entire TXD descriptor was used but instead of a subset of it named TXINFO. Finally this also fixes numerous other bugs related to incorrect beacon handling or beacon related code. Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2008-02-28rt2x00: Add link tuner safe RX toggle statesIvo van Doorn1-1/+5
This adds 2 new states which both are used to toggle the RX. These new states are required for usage inside the link tuner thread, because the normal RX toggling will stop the link tuner thread. While it is possible that the link tuner thread itself is the caller of the RX toggle (when using software antenna diversity). Signed-off-by: Ivo van Doorn <IvDoorn@gmail.com> Signed-off-by: John W.

2008-01-29rt2x00: Data and desc pointer initializationIvo van Doorn1-7/+4
rt2500usb and rt73usb data and desc pointer initialization was incorrect because it was using uninitialized variables to determine the length. In addition rt2500usb used skb_pull and removed the ieee80211 from each received frame instead of using skb_trim to remove the device descriptor from the frame. Finally this also fixes the descriptor override when 4 byte aligning occured. We still need a completely valid descriptor when using the TX/RX dumping capabilities in debugfs.
