2011-03-04rt2x00: Revise irqmask locking for PCI devicesHelmut Schaa4-33/+22
The PCI device irqmask is locked by a spin_lock. Currently spin_lock_irqsave is used everywhere. To reduce the locking overhead replace spin_lock_irqsave in hard irq context with spin_lock and in soft irq context with spin_lock_irq.

2011-03-04rt2x00: Fix rt2800 key assignment in multi bssid setupsHelmut Schaa1-13/+30
When setting up multiple BSSIDs in AP mode on an rt2800pci device we previously used the STAs AID to select an appropriate key slot. But since the AID is per VIF we can end up with two STAs having the same AID and thus using the same key index. This resulted in one STA overwriting the key information of another STA. Fix this by simply searching for the next unused entry in the pairwise key table. Also bring the key table init in sync with deleting keys by initializing the key table entries to 0 instead of 1.

2011-03-04rt2x00: Optimize TX descriptor handlingHelmut Schaa12-55/+79
HT and no-HT rt2x00 devices use a partly different TX descriptor. Optimize the tx desciptor memory layout by putting the PLCP and HT substructs into a union and introduce a new driver flag to decide which TX desciptor format is used by the device.

Add a new driver flag to shortcut the software sequence number generation on devices that don't need it. rt61pci, rt73usb and rt2800* seem to make use of a hw sequence counter while rt2400pci and rt2500* need to do it in software.

2011-03-04rt2x00: Optimize calls to rt2x00queue_get_queueHelmut Schaa6-8/+25
In some cases (tx path for example) we don't need to check for non-tx queues in rt2x00queue_get_queue. Hence, introduce a new method rt2x00queue_get_tx_queue that is only valid for tx queues and use it in places where only tx queues are valid. Furthermore, this new method is quite short and as such can be inlined to avoid the function call overhead. This only converts the txdone functions of drivers that don't use an ATIM queue and the generic tx path.

2011-03-03wl12xx: Switch to level trigger interruptsIdo Yariv2-2/+2
The interrupt of the wl12xx is a level interrupt in nature, since the interrupt line is not auto-reset. However, since resetting the interrupt requires bus transactions, this cannot be done from an interrupt context. Thus, requesting a level interrupt would require to disable the irq and re-enable it after the HW is acknowledged. Since we now request a threaded irq, this can also be done by specifying the IRQF_ONESHOT flag. Triggering on an edge can be problematic in some platforms, if the sampling frequency is not sufficient for detecting very frequent interrupts. In case an interrupt is missed, the driver will hang as the interrupt line will stay high until it is acknowledged by the driver, which will never happen. Fix this by requesting a level triggered interrupt, with the IRQF_ONESHOT flag.

2011-03-03wl12xx: Switch to a threaded interrupt handlerIdo Yariv10-81/+113
To achieve maximal throughput, it is very important to react to interrupts as soon as possible. Currently the interrupt handler wakes up a worker for handling interrupts in process context. A cleaner and more efficient design would be to request a threaded interrupt handler. This handler's priority is very high, and can do blocking operations such as SDIO/SPI transactions. Some work can be deferred, mostly calls to mac80211 APIs (ieee80211_rx_ni and ieee80211_tx_status). By deferring such work to a different worker, we can keep the irq handler thread more I/O responsive. In addition, on multi-core systems the two threads can be scheduled on different cores, which will improve overall performance. The use of WL1271_FLAG_IRQ_PENDING & WL1271_FLAG_IRQ_RUNNING was changed. For simplicity, always query the FW for more pending interrupts. Since there are relatively long bursts of interrupts, the extra FW status read overhead is negligible. In addition, this enables registering the IRQ handler with the ONESHOT option.

2011-03-03wl12xx: Change claiming of the SDIO busIdo Yariv1-10/+0
The SDIO bus is claimed and released for each SDIO transaction. In addition to the few CPU cycles it takes to claim and release the bus, it may also cause undesired side effects such as the MMC host stopping its internal clocks. Since only the wl12xx_sdio driver drives this SDIO card, it is safe to claim the SDIO host once (on power on), and release it only when turning the power off. This patch was inspired by Juuso Oikarinen's ([email protected]) patch "wl12xx: Change claiming of the (SDIO) bus".

2011-03-03wl12xx: Reorder data handling in irq_workIdo Yariv1-5/+5
The FW has a limited amount of memory for holding frames. In case it runs out of memory reserved for RX frames, it'll have no other choice but to drop packets received from the AP. Thus, it is important to handle RX data interrupts as soon as possible, before handling anything else. In addition, since there are enough TX descriptors to go around, it is better to first send TX frames, and only then handle TX completions.

2011-03-03wl12xx: Don't rely on runtime PM for toggling powerIdo Yariv1-2/+14
Runtime PM might not always be enabled. Even if it is enabled in the running kernel, it can still be temporarily disabled, for instance during suspend. Runtime PM is opportunistic in nature, and should not be relied on for toggling power. In case the interface is removed and re-added while runtime PM is disabled, the FW will fail to boot, as it is mandatory to toggle power between boots. For instance, this can happen during suspend in case one of the devices fails to suspend before the MMC host suspends, but after mac80211 was suspended. The interface will be removed and reactivated without toggling the power. Fix this by calling mmc_power_save_host/mmc_power_restore_host in wl1271_sdio_power_on/off functions. It will toggle the power to the chip even if runtime PM is disabled. The runtime PM functions should still be called to make sure runtime PM does not opportunistically power the chip off (e.g. after resuming from system suspend).
