2016-09-16iwlwifi: pcie: merge iwl_queue and iwl_txqSara Sharon
The original intent was to have the general iwl_queue shared between RX and TX queues, but it is not the actual status. Since it is not shared with any struct but iwl_txq, it adds unnecessary complexity. Merge those structs.

2016-09-16iwlwifi: change byte count table for a000 devicesSara Sharon
Since TFD was enlarged to 256 bytes, the fetch of the TFD itself is very expensive. To make DRAM to SRAM more efficient, bits 12-13 will indicate the number of 64 byte chunks that should be transferred to SRAM.

2016-09-15iwlwifi: mvm: support new shared memory config APISara Sharon
In a000 devices we have 15 fifos, so in the shared memory config the number of tx fifos in the array was changed accordingly. As it is in the middle of the struct, the parsing code needs to be duplicated. To minimize the duplication, do not save variables we never actually use.

2016-09-15iwlwifi: mvm: remove dump of locked registersSara Sharon

2016-09-15iwlwifi: mvm: call a different txq_enable functionSara Sharon
Since the SCD_QUEUE_CFG command was introduced the driver calls iwl_trans_txq_enable_cfg() with a NULL for scd_cfg parameter. This makes the transport avoid writing to the SCD pointers, since it can cause races with firmware, which is also accessing the registers. The transport only updates the write pointer in that case. Fix a wrong call to iwl_trans_txq_enable() which caused a scd_cfg parameter to be sent to transport, resulting with an access to SCD registers.

2016-08-30iwlwifi: pcie: refrain from SCD accessesSara Sharon

2016-08-30iwlwifi: mvm: support txq tid owner changeLiad Kaufman
Every active TXQ is assigned to a TID given through the SCD_CONFIG_CMD, and acts as an identifier in the FW. However, there may be cases this ownership needs to be changed. For example, in the following scenario: 1. TID x is owner of a queue 2. Due to a shortage of queues, TID y and z share with x 3. TID x becomes inactive and needs to be removed from the shared queue. In this scenario, if another queue is freed and traffic on x continues, we can't allocate it a new queue as long as it is the owner of the first queue. Support moving ownership of a TXQ to a different TID (same STA) without stopping the queue. Signed-off-by: Liad Kaufman <liad.kaufman@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>

2016-08-30iwlwifi: mvm: re-assign old queues after hw restart in dqa modeLiad Kaufman
When working in DQA mode, if a queue is shared and a HW restart occurs, there might be a possible race condition between stations on the queues, and an existing queue might be left with no queues. To solve this, make sure in DQA mode to re-assign the same queues as before the HW restart. Signed-off-by: Liad Kaufman <liad.kaufman@intel.com> Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
2016-08-30iwlwifi: mvm: keep track of tid associated with each queueLiad Kaufman

If later there is a need to use this TID on a different queue instead, it first needs to be unassociated from the first queue. Keep track for every queue what TID is associated with it.

2016-07-06iwlwifi: pcie: fix a race in firmware loading flowEmmanuel Grumbach
Upon firmware load interrupt (FH_TX), the ISR re-enables the firmware load interrupt only to avoid races with other flows as described in the commit below. When the firmware is completely loaded, the thread that is loading the firmware will enable all the interrupts to make sure that the driver gets the ALIVE interrupt. The problem with that is that the thread that is loading the firmware is actually racing against the ISR and we can get to the following situation: CPU0 CPU1 iwl_pcie_load_given_ucode ... iwl_pcie_load_firmware_chunk wait_for_interrupt <interrupt> ISR handles CSR_INT_BIT_FH_TX ISR wakes up the thread on CPU0 /* enable all the interrupts * to get the ALIVE interrupt */ iwl_enable_interrupts ISR re-enables CSR_INT_BIT_FH_TX only /* start the firmware */ iwl_write32(trans, CSR_RESET, 0); BUG! ALIVE interrupt will never arrive since it has been masked by CPU1. In order to fix that, change the ISR to first check if STATUS_INT_ENABLED is set. If so, re-enable all the interrupts. If STATUS_INT_ENABLED is clear, then we can check what specific interrupt happened and re-enable only that specific interrupt (RFKILL or FH_TX). All the credit for the analysis goes to Kirtika who did the actual debugging work.

2016-07-06iwlwifi: decouple PCIe transport from mac80211Johannes Berg
The PCIe transport needs to store two pointers in each TX SKB, and currently assumes mac80211's ieee80211_tx_info is present in the CB to do that. In order to remove that assumption, have the opmodes pass in the offset to where the pointers can be stored in the CB and use the offset in the PCIe code. To make the disentanglement complete, remove mac80211.h includes from everywhere in the generic iwlwifi code. This required adding an include of cfg80211.h in one place.
