* wil6210: remove SSID debugfsJohannes Berg2017-10-27
| | | | | | | | | | | | | | | This driver shouldn't be using wdev->ssid to start with, as it's more or less an internal field in cfg80211 used for various purposes. Reading it is possible through nl80211, even if that's not really what we should be doing there for anything but AP type interfaces. It *really* shouldn't allow modifying it! Remove the whole debugfs entry. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

* wil6210: add support for PCIe D3hot in system suspendMaya Erez2017-06-21
| | | | | | | | | | | | | In order to preserve the connection in suspend/resume flow, wil6210 host allows going to PCIe D3hot state in suspend, instead of performing a full wil6210 device reset. This requires the platform ability to initiate wakeup in case of RX data. To check that, a new platform API is added. In addition, add cfg80211 suspend/resume callbacks implementation.

* wil6210: prevent deep sleep of 60G device in critical pathsMaya Erez2016-04-26
| | | | | | | | | | | | | | | | | In idle times 60G device can enter deep sleep and turn off its XTAL clock. Host access triggers the device power-up flow which will hold the AHB during XTAL stabilization until device switches from slow-clock to XTAL clock. This behavior can stall the PCIe bus for some arbitrary period of time. In order to prevent this stall, host can vote for High Latency Access Policy (HALP) before reading from PCIe bus. This vote will wakeup the device from deep sleep and prevent deep sleep until unvote is done. Signed-off-by: Maya Erez <qca_merez@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@qca.qualcomm.com>

* wil6210: add support for discovery mode during scanLior David2016-03-07
| | | | | | | | | | | | | | | | | | Add support for discovery mode during scan. When discovery mode is active, station transmits special beacons while scanning. This can optimize the scan mainly when there is only one AP/PCP around. Discovery mode is implicitly used by firmware during P2P search. Since there is currently no use case where user space has a reason to directly control discovery mode, we expose it only through a debugfs flag. Also fix name confusion in the wmi_scan_type enumeration. The type previously called WMI_LONG_SCAN is actually WMI_ACTIVE_SCAN.

* wil6210: add advanced interrupt moderationVladimir Kondratiev2015-01-15
| | | | | | | | | | | | | | | | | | | | | | | | | Add advanced interrupt moderation support available since "Sparrow B0". Legacy interrupt moderation used only one counter to moderate tx, rx, and misc interrupts. Advanced interrupt moderation bypasses misc, and handles separately tx and rx interrupts. In addition it has two timers for each interrupt type. Max burst duration timer which defines how long to postpone interrupt after first event (receive event for rx and tx complete event for tx), and interframe timeout which defines how to determine the end of the burst and issue interrupt even if the first timer still pending. Capabilities flags in wil_priv is set on initialization according to HW. The rest of the code checks for advanced interrupt capability bit in capabilities flags field. Debugfs is split accordingly: "legacy" interrupt moderation remains unchanged, new debugs files added for advanced interrupt moderation support. Module params are aligned to support advanced interrupt moderation (tx & rx). When not available (for legacy interrupt moderation) will use only rx configuration; Tx configuration will be ignored in this case.

| | | | | | | | | | | | | | | | When printing VRING on debugfs (file "vrings"), software head & tail indexes were printed in decimal format while hardware tail in hexadecimal only. It is not comfortable to compare indexes in different formats; on the other hand, hexadecimal output useful to see hardware glitches. To serve all purposes, print hardware tail in both decimal and hexadecimal formats. Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

Eventually, it gets event confirming BACK agreement - WMI_BA_STATUS_EVENTID with negotiated parameters. On this event, update Tx vring data (struct vring_tx_data) and display BACK parameters on debugfs - recipient Rx side (recipient) firmware informs driver about ADDBA with WMI_RCP_ADDBA_REQ_EVENTID, driver process it in service work queue wq_service. It adjusts parameters and sends response with WMI_RCP_ADDBA_RESP_CMDID, and final confirmation provided by firmware with WMI_ADDBA_RESP_SENT_EVENTID. In case of success, driver updates Rx BACK reorder buffer. policy for BACK parameters: - aggregation size (agg_wsize * MPDUsize)) to not exceed 64Kbytes DELBA flow for: - originator driver decides to terminate BACK, it sends WMI_VRING_BA_DIS_CMDID and updates struct vring_tx_data associated with vring; ignore WMI_DELBA_EVENTID. - recipient firmware informs driver with WMI_DELBA_EVENTID, driver deletes correspondent reorder buffer ADDBA request processing requires sending WMI command, therefore it is processed in work queue context. Same work queue used as for connect, it get renamed to wq_service Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
