2010-10-06ath9k_hw: clean up register write bufferingFelix Fietkau
Throughout the code, DISABLE_REGWRITE_BUFFER is always called right after REGWRITE_BUFFER_FLUSH. Since that's unlikely to change any time soon, that makes keeping those ops separate rather pointless, as it only increases code size and line number counts.

2010-10-06ath9k_hw: merge codepaths that access the cycle counter registersFelix Fietkau
The cycle counters are used by ANI to determine the amount of time that the radio spent not receiving or transmitting. They're also used for debugging purposes if the baseband watchdog on AR9003 detects a lockup. In the future, we want to use these counters to determine the medium utilization and export this information via survey. For that, we need to make sure that the counter is only accessed from one place, which also ensures that wraparounds won't occur at inconvenient points in time.

2010-10-06ath9k_hw: clean up calibration flagsFelix Fietkau
The calibration actual calibration flags are only used by the per chip family source files, so it makes more sense to define them in those files instead of globally. That way the code has to test for less flags. Also instead of using a separate callback for testing whether a particular calibration type is supported, simply adjust ah->supp_cals in the calibration init which is called right after the hardware reset, before any of the calibrations are run.

2010-10-05ath9k: get correct tx gain type in ath9k_hw_4k_get_eepromGabor Juhos
The base_eep_header_4k structure contains information that the device supports high power tx gain table or not. However the ath9k_hw_4k_get_eeprom function does not return that value when it is called with EEP_TXGAIN_TYPE. This leads to that the tx gain initialization will use the init values from the original tx gain table even if the device inidicates that the high power table should be used.

2010-10-05rt2x00: Work around hw aggregation oddity in rt2800Helmut Schaa
If a frame is not meant to be sent as AMPDU or part of it the hw might still decide to aggregate this frame if a previous frame started an AMPDU. However, this will limit the usefulness of the reported tx rate since the reported rate will be the one specified in the TXWI of the first frame and thus it is not possible to reliably caculate the number of retrys by substracting the reported tx rate from the tx rate in the TXWI. To fix this issue, only report the successful rate for frames that were not meant to be aggregated but ended up in an aggregate. Example: Frame A (MCS7, AMPDU=1) B (MCS7, AMPDU=1) C (MCS12, AMDPU=0, PROBE_RATE) Although frame C shoudn't be aggregated the hw might sill put it into an AMPDU together with A and B. If the transmission succeeds the tx status will contain MCS7 for all three frames. In that case we should only report MCS7 as success rate and avoid reporting MCS12-MCS8 as failed tx attempts as this will affect the future rate control decisions. This oddity might strike us in other scenarious as well but the most common "wrong" report happened for frames used to probe a different tx rate. This improves the rate control decisions notable.

When rt2x00lib_enable_radio fails to enable the radio, rt2x00lib_start will call rt2x00queue_uninitialize to uninitialize the queues. Since, the queues are not initialized here but already in rt2x00lib_initialize we shouldn't uninitialize the queues here. Otherwise, a consecutive call to rt2x00lib_start will oops (see below) because it assumes the queues are already initialized.

2010-10-05rt2x00: Improve TX status entry validationIvo van Doorn
The TX_STA_FIFO contains some information for identifying a outgoing frame, however matching by WCID and ACK status is not sufficient to 100% identify the macthing queue_entry structure (containing the SKB buffer) which belongs to the status report. Within TX_STA_FIFO we have a 4-bit field named PACKETID, which is currently used to encode the queue id. The queue ID is however limited to values from 0 to 3, which means 2 bits are sufficient to encode the value. With the remaining 2 bits we can encode a partial queue_entry index number. The value of PACKETID is not allowed to become 0, with the queue ID ranging from 0 to 3, at least one of the bits for the entry identification must be 1. That leaves us with 3 possible values we can still encode in the bits. Altough this doesn't allow 100% accurate matching of the TX_STA_FIFO queue to a queue_entry structure, it at least improves the accuracy. This allows us to better detect if we have missed the TX_STA_FIFO report, which in turn reduces the number of watchdog warnings regarding the TX status timeout.

2010-10-05rt2x00: correctly set max_report_rates in rt61pci and rt2800Helmut Schaa
rt61pci and rt2800 devices can use up to 7 different rates per tx frame. However, the device uses a global fallback table. Hence, the rc algortihm cannot specify multiple rates to try but the device is able to report multiple rates (based on the retry table). Specify that behavior by correctly setting max_report_rates and max_rates. This makes rt2x00 and minstrel play nicer together.

2010-10-05rt2x00: Fix race between dma mapping and clearing rx entries in rt2800pciHelmut Schaa
During rx, rt2x00lib calls rt2800pci_fill_rxdone to read the RX descriptor. At that time the skb is already dma unmapped but no new skb was dma mapped for this entry again. However, rt2800pci_fill_rxdone also moves the hw rx queue index, marking this entry to be available for reuse. Since no new skb was dma mapped and also the previous skb was unmapped this might lead to strange hw behavior. To fix this issue move the hw rx queue index increment to rt2800pci_clear_entry where a new skb was already dma mapped and can be safely used by the hw.

2010-10-05rt2x00: rework tx status handling in rt2800pciHelmut Schaa
This patch changes the way tx status reports are handled by rt2800pci. Previously rt2800pci would sometimes lose tx status reports as the TX_STA_FIFO register is a fifo of 16 entries that can overflow in case we don't read it often/fast enough. Since interrupts are disabled in the device during the execution of the interrupt thread it happend sometimes under high network and CPU load that processing took too long and a few tx status reports were dropped by the hw. To fix this issue the TX_STA_FIFO register is read directly in the interrupt handler and stored in a kfifo which is large enough to hold all status reports of all used tx queues. To process the status reports a new tasklet txstatus_tasklet is used. Using the already used interrupt thread is not possible since we don't want to disable the TX_FIFO_STATUS interrupt while processing them and it is not possible to schedule the interrupt thread multiple times for execution. A tasklet instead can be scheduled multiple times which allows to leave the TX_FIFO_STATUS interrupt enabled while a previously scheduled tasklet is still executing. In short: All other interrupts are handled in the interrupt thread as before. Only the TX_FIFO_STATUS interrupt is partly handled in the interrupt handler and finished in the according tasklet. One drawback of this patch is that it duplicates some code from rt2800lib. However, that can be cleaned up in the future once the rt2800usb and rt2800pci tx status handling converge more. Using this patch on a Ralink RT3052 embedded board gives me a reliable wireless connection even under high CPU and network load. I've transferred several gigabytes without any queue lockups.

The hardware rx-filter was essentially disabled, because of a serve, yet unidentifiable problem with iwlagn. Due to these circumstances the driver and mac80211 were left with the job of filtering. This is very unfortunate and has proven to be expensive in terms of latency, memory and load. Therefore the new 1.8.8.3 firmware introduces a flexible filtering infrastructure which allows the driver to offload some of the checks (FCS & PLCP crc check, RA match, control frame filter, etc...) whenever possible.

2010-10-05wl1271: Indicate disconnection on hardware failureJuuso Oikarinen
In the event of a hardware failure, reconfiguring a live connection back with the wl1271 chip does not work as expected. The chip has management features which require setting up the association from scratch to work correctly. To ensure this is done every time, in managed mode, when associated, indicate connection loss to the mac80211 before asking to reconfigure the hardware.

2010-10-05wl1271: Move work-init calls to hw allocationJuuso Oikarinen
Due to legacy reason, dating back to when the wl1251 and wl1271 still were a unified driver, some work-structures are initialized on hardware startup. The hardware recovery code creates a scenario in which it is possible for a workstruct to be re-initialized while the work-function itself is running, which causes a kernel WARNing and a subsequent reboot. To remedy this, move the work initialization calls to the hw allocation, which is the logically correct place for them anyway.

2010-10-05wl1271: Support firmware TX packet aggregationIdo Yariv
Instead of sending one packet at a time to the firmware, try to send all available packets at once. This optimization decreases the number of transactions, which saves CPU cycles and increases network throughput.
