2016-07-08ath10k: simplify pktlog htt event processingAshok Raj Nagarajan2-24/+3
It is expected that all pktlog events for 10.4 firmware based solutions should come through CE8 where as in case of 10.2 firmware based solutions, it should come through one of the HTT events (HTT_T2H_MSG_TYPE_PKTLOG). But from experiments with 10.4 based solutions, it is observed that pktlog event for ATH_PKTLOG_TYPE_TX_MSDU_ID is coming through HTT pktlog event. Currently, we always parse with 10.2 pktlog header which will lead to pktlog decoding issues (payload length mismatch exceptions) For trace points, it is required to provide only the payload size. So fixing this by simplifying the payload size calculation without the use of ath10k pktlog headers. While there, remove the unused ath10k pktlog headers.

cfg80211/nl80211 interface changes for per STA total rx-duration and very basic 'ath10k_sta_statistics' mac80211 callback is implemented to extend support for per station statistics from the driver.

2016-07-08ath10k: fix 10.4 extended peer stats updateMohammed Shafi Shajakhan6-22/+119
10.4 'extended peer stats' will be not be appended with normal peer stats data and they shall be coming in separate chunks. Fix this by maintaining a separate linked list 'extender peer stats' for 10.4 and update rx_duration for per station statistics. Also parse through beacon filter (if enabled), to make sure we parse the extended peer stats properly. This issue was exposed when more than one client is connected and extended peer stats for 10.4 is enabled The order for the stats is as below S - standard peer stats, E- extended peer stats, B - beacon filter stats {S1, S2, S3..} -> {B1, B2, B3..}(if available) -> {E1, E2, E3..} Fixes: f9575793d44c ("ath10k: enable parsing per station rx duration for 10.4") Signed-off-by: Mohammed Shafi Shajakhan <[email protected]> Signed-off-by: Kalle Valo <[email protected]>
2016-07-06mac80211: Add support for beacon report radio measurementAvraham Stern12-25/+93

Report the scan start time (in terms of TSF) 3. Report each BSS's detection time (also in terms of TSF) TSF times refer to the BSS that the interface that requested the scan is connected to.

2016-07-06nl80211: support beacon report scanningAvraham Stern12-23/+95
Beacon report radio measurement requires reporting observed BSSs on the channels specified in the beacon request. If the measurement mode is set to passive or active, it requires actually performing a scan (passive or active, accordingly), and reporting the time that the scan was started and the time each beacon/probe was received (both in terms of TSF of the BSS of the requesting AP). If the request mode is table, this information is optional. In addition, the radio measurement request specifies the channel dwell time for the measurement. In order to use scan for beacon report when the mode is active or passive, add a parameter to scan request that specifies the channel dwell time, and add scan start time and beacon received time to scan results information. Supporting beacon report is required for Multi Band Operation (MBO).

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.
