2016-08-30iwlwifi: mvm: use defines for SCD_CONFIG_CMD enablementLiad Kaufman3-10/+19
Due to the addition of another option in the SCD_CONFIG_CMD's %enable field, change the assignment of this field to use defines rather than hard-code the value itself. Signed-off-by: Liad Kaufman <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2016-08-30iwlwifi: mvm: re-assign old queues after hw restart in dqa modeLiad Kaufman1-2/+70
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 <[email protected]> Signed-off-by: Luca Coelho <[email protected]>
2016-08-30iwlwifi: mvm: keep track of tid associated with each queueLiad Kaufman3-0/+11
When sending the SCD_QUEUE_CONFIG command, the queue is associated to a specific TID. 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.

2016-08-30iwlwifi: mvm: re-aggregate shared queue after unsharingLiad Kaufman5-28/+205

The 9000 hardware will de-aggregate AMSDUs. In the process it will copy the mac header "as is" to the new MPDUs. This means driver should allow the same PN for MPDUs originated from the same AMSDU.

2016-07-06iwlwifi: pcie: generalize and increase the size of scratchbufSara Sharon2-58/+54
Currently the scratch buffer is set to 16 bytes and indicates the size of the bi-directional DMA. However, next HW generation will perform additional offloading, and will write the result in the key location of the TX command, so the size of the bi-directional consistent memory should grow accordingly - increase it to 40.

2016-07-06iwlwifi: pcie: fix a race in firmware loading flowEmmanuel Grumbach3-17/+28
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 Berg8-25/+37
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.

2016-07-06iwlwifi: mvm: free RX reorder buffer on restartSara Sharon1-3/+4

2016-07-06iwlwifi: mvm: support dqa-mode scd queue redirectionLiad Kaufman1-5/+110
Make sure that in DQA mode, the SCD's configuration of a queue is redirected to the lower AC of the streams of the queue. Make sure that this queue is redirected to the lowest AC when adding a new RA/TID to an existing queue. If it isn't - redirect the queue. Also, as redirection revealed a bug in the marking of a shared queue, this patch contains a small fix to make sure a shared queue maintains the appropriate "shared queue marking".

The TX fifos are arranged consecutively in the SMEM, beginning with the regular fifos, and tailed by the internal fifos. In the current code, while trying to read the internal fifos, we read the fifos beginning with the index zero. By doing this we actually re-read the regular fifos.

This fixes a pretty ancient bug that hasn't manifested itself until now. The scratchbuf for command queue is allocated only for 32 slots but is accessed with the queue write pointer - which can be up to 256. Since the scratch buf size was 16 and there are up to 256 TFDs we never passed a page boundary when accessing the scratch buffer, but when attempting to increase the size of the scratch buffer a panic was quick to follow when trying to access the address resulted in a page boundary.

2016-07-06iwlwifi: pcie: enable interrupts before releasing the NIC's CPUEmmanuel Grumbach1-1/+4
The NIC's CPU gets started after the firmware has been written to its memory. The first thing it does is to send an interrupt to let the driver know that it is running. In order to get that interrupt, the driver needs to make sure it is not masked. Of course, the interrupt needs to be enabled in the driver before the CPU starts to run. I mistakenly inversed those two steps leading to races which prevented the driver from getting the alive interrupt from the firmware. Fix that.
