2011-04-19wl12xx: move hardcoded hci_io_ds value into the conf structLuciano Coelho
Instead of hardcoding the hci_io_ds configuration that we write to the SDIO_IO_DS top registed, read it from the default configuration so that it's easier to change for different platforms. Reported-by: Ido Yariv <ido@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>

2011-04-19wl12xx: Handle platforms without level trigger interruptsIdo Yariv
Some platforms are incapable of triggering on level interrupts. Add a platform quirks member in the platform data structure, as well as an edge interrupt quirk which can be set on such platforms. When the interrupt is requested with IRQF_TRIGGER_RISING, IRQF_ONESHOT cannot be used, as we might miss interrupts that occur after the FW status is cleared and before the threaded interrupt handler exits. Moreover, when IRQF_ONESHOT is not set, iterating more than once in the threaded interrupt handler introduces a few race conditions between this handler and the hardirq handler. Currently this is worked around by limiting the loop to one iteration only. This workaround has an impact on performance. To remove to this restriction, the race conditions will need to be addressed.

2011-04-19wl12xx: Simplify TX blocks accountingIdo Yariv
The total number of TX memory blocks may change when the dynamic memory option is enabled. The current implementation only tracks the available memory blocks, which over-complicates TX blocks accounting. By tracking the number of allocated blocks, calculation of the number of available blocks becomes simpler and cleaner. It simply equals the total number of TX memory blocks minus the allocated ones. Also, remove some unnecessary castings and use union member accesses instead.

2011-04-19wl12xx: Clean up the dummy packet mechanismIdo Yariv
The current implementation allocates a skb each time one is requested by the firmware. Since dummy packets are handled differently than regular packets, the skb needs to be marked. Currently, this is done by setting the pkt_type member to 5. This might not be safe, as we cannot be sure that there won't be any other packets with this pkt_type value. Since the packet does not change from one request to another, we can simply allocate a dummy packet template and always send it. All changes to the skb done during packet preparation must be reverted, so the same skb can be reused. The dummy packets are not transmitted, therefore there's no need to set the BSSID or our own MAC address. In addition, the header portion of the packet was zeroed by mistake, so fix that as well.

2011-04-19wl12xx: Clean up the block size alignment codeIdo Yariv
Simplify and clean up the block size alignment code: 1. Set the block size according to the padding field type, as it cannot exceed the maximum value this field can hold. 2. Move the alignment code into a function instead of duplicating it in multiple places. 3. In the current implementation, the block_size member can be misleading because a zero value actually means that there's no need to align. Declare a block size alignment quirk instead.

2011-04-19wl12xx: fix "JOIN while associated" commentaryOhad Ben-Cohen
Issuing multiple JOIN commands to the wl12xx's firmware, while we're associated, might have undesired implications, so the driver prints a message when that happens, and warn developers who check out the source. Update the commentary in order to consider the one valid scenario where this can happen: roaming. Cautiously keep the message for now, until we either gain confidence there are no unintentional JOIN-while-associated events, or until we move to the new multi-role fw who solves this multiple-join issue for good.

2011-04-19wl12xx: fix roamingOhad Ben-Cohen
The wl12xx device normally drops all frames coming from BSSID it is not joined with. This behavior is configured today by the wl12xx driver in response to a handful of ieee80211_bss_change and ieee80211_conf_changed notification flags, such as BSS_CHANGED_ASSOC, BSS_CHANGED_BSSID, IEEE80211_CONF_CHANGE_IDLE, etc.. This breaks when we roam to a new BSSID, where authentication frames are sent before any BSS_CHANGED/CONF_CHANGED flags are received. When this happens the hardware silently drops the authentication responses, and the roaming fails. Ideally this aggressive filtering behavior of the device should be disabled upon a notification from mac80211. Such notification will take place after multi-channel support will be added: mac80211 will likely send a remain-on-channel notification to drivers when entering sensitive states (like authentication), otherwise the firmware might jump to different channels (to serve a different role). Until those notifications materialize, disable the hw BSSID filter when authentication requests are sent, so roaming would work.

2011-04-19wl12xx: rearrange some ELP wake_up/sleep callsEliad Peller
ELP (Extremely/Enhanced Low Power, or something like that ;)) refers to the powerstate of the 12xx chip, in which very low power is consumed, and no commands (from the host) can be issued until the chip is woken up. Wakeup/sleep commands must be protected by a wl->mutex, so it's generally a good idea to call wakeup/sleep along with the mutex lock/unlock (where needed). However, in some places the wl12xx driver calls wakeup/sleep in some "inner" functions. This result in some "nested" wakeup/sleep calls which might end up letting the chip go to sleep prematurely (e.g. during event handling). Fix it by rearranging the elp calls to come along with mutex_lock/unlock.

2011-03-03wl12xx: Switch to a threaded interrupt handlerIdo Yariv
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: Reorder data handling in irq_workIdo Yariv
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.

2011-01-24wl12xx: Increase scan channel dwell time for passive scansJuuso Oikarinen
The passive scan channel dwell time currently used is 30-60TU. A typical beacon interval for AP's is 100TU. This leads to a ~30% worst-case probability of finding an AP via passive scanning. For 5GHz bands for DFS frequencies passive scanning is the only scanning option. Hence for these, the probability of finding an AP is very low. To fix this, increase the passive channel scan dwell times (also the early leave value, as 5GHz channels are still typically very silent.) Use a value of 100TU, because that covers most typical AP configurations. Based on testing the probability of finding an AP (100TU beacon interval) on a single scan round are as follows (based on 100 iterations): dwell min/max (TU) | probability ---------------------+------------ 30/60 | 35% 60/60 | 56% 80/80 | 77% 100/100 | 100% Total scan times now and after the change: Region | Before (s) | After (s) -------+------------+---------- 00 | 0.77 | 1.48 FI | 0.95 | 2.01 US | 0.91 | 1.76 Signed-off-by: Juuso Oikarinen <juuso.oikarinen@nokia.com> Reviewed-by: Luciano Coelho <coelho@ti.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
