| | * | iwlwifi: mvm: fix the net-detect SSIDs report orderLuciano Coelho2015-05-281-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | After the scan refactor, the order of the SSIDs passed to the firmware in all scans (including net-detect) are inverted. This was causing the reporting code to use the wrong SSIDs. To fix this, invert the array index when accessing the saved match SSIDs to report the wake-up.

| | * | iwlwifi: mvm: Configure agg. queue before assigning it to STAAndrei Otcheretianski2015-05-281-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to imeplement the extended VI session feature for Miracast, the FW requires to detect the VI queue. The detection of the VI queue is done when it is assigned to a STA with ADD_STA command, so by this time the FW expects the queue to be already configured (mapped to VI AC and aggregation enabled). Previously, the queue configuration was done after STA modificaton which broke the extended VI session feature and resulted in higher latencies. Fix this by calling iwl_mvm_enable_agg_txq before station modification.

However, all the products that currently require this don't have a need for the full randomisation. Therefore, advertise the feature anyway which results in host- based randomisation, done whenever the system suspends. This is sufficient for the platforms currently requiring this feature. If we ever extend this in the future to do full randomisation in the firmware, then certainly this will still be sufficient for the current requirements, so it doesn't make a lot of sense to split the feature bits.

While doing it, it moved the ROC reference release to a common work item, which is being called for both the ROC and aux ROC flows. This resulted in invalid reference accounting, as no reference was taken in case of aux ROC, while a reference was released on completion. Fix it by adding a reference for the aux ROC as well, and release only the relevant references on completion (according to the set bits).

So adding a check for the presence of this property before attempting to parse and map the interrupt. If not present or parsing fails return and fallback to in-band sdio interrupt.

As noticed by Joe Perches I reuse ar9002_hw_spur_mitigate (const) version of declarations for pilot_mask_reg and chan_mask_reg. There should be no other difference with original code.

| * | | | rtlwifi: Remove the clear interrupt routine from all driversVincent Fann2015-05-265-83/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Several of these drivers have there TX randomly blocked for 3~5 seconds while measuring tx throughput (iperf). The root couse happens in rtl_pci_flush(). The function uses a while-loop to wait for TX queue length to decrease to 0. The TX queue length counts the number of packets that are queued in the driver. The driver relys on the TX OK interrupt to return skb and reduce TX queue length. The interrupt subroutine disables interupts, reads the interrupt registers, and then clears the registers in the beginning of _rtl_pci_interrupt(). After all interupts process are finished, the driver invokes enable_interrupt() to enable interupts. This behavior is normal for an interrupt subroutine. But enable_interrupt() invokes clear_interrupt() again. This unexpected interrupt clearing may cleari me fresh TX OK interrupts. These missing interrupts cause TX queue length to never reduce to 0i, which causes rtl_pci_flush() to be stuck in unterminated while-loop. This patch removes clear_interrupt() in enable_interrupt() to avoid this behavior.
