2015-01-15wil6210: ADDBA/DELBA flowsVladimir Kondratiev1-3/+50
Introduce BACK establishment procedures; decision logic is not implemented yet; debugfs entry 'addba' used to manually trigger addba/delba for ringid 0. debugfs usage: to establish BACK with agg_wsize 16: echo 16 > /sys/kernel/debug/ieee80211/phy0/wil6210/addba to delete BACK: echo 0 > /sys/kernel/debug/ieee80211/phy0/wil6210/addba to change agg_wsize, one need to delete BACK and establish it anew ADDBA flow for: - originator Tx side (initiator) sends WMI_VRING_BA_EN_CMDID providing agg_wsize and timeout parameters. 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>

2014-10-02wil6210: manual FW error recovery modeVladimir Kondratiev1-0/+67
Introduce manual FW recovery mode. It is activated if module parameter @no_fw_recovery set to true. May be changed at runtime. Recovery information provided by new "recovery" debugfs file. It prints: mode = [auto|manual] state = [idle|pending|running] In manual mode, after FW error, recovery won't start automatically. Instead, after notification to user space, recovery waits in "pending" state, as indicated by the "recovery" debugfs file. User space tools may perform data collection and allow to continue recovery by writing "run" to the "recovery" debugfs file. Alternatively, recovery pending may be canceled by stopping network interface i.e. 'ifconfig wlan0 down' Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W.

2014-06-19wil6210: Tx performance monitoringVladimir Kondratiev1-2/+14
For performance monitoring, trace time intervals when Tx vring is idle/not idle. Use CPU cycle counter for this, because jiffies is too rough, and other precise time measurement methods involve overhead while get_cycles() should be fast. This used to provide some estimation for percentage when Tx vring was idle, i.e. when hardware is under-utilized. Estimation is not precise because of many reasons - CPU frequency scaling, grt_cycles() may be per core etc. But still, it is good estimation Signed-off-by: Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> Signed-off-by: John W.

Pull VFS updates from Al Viro, Misc cleanups all over the place, mainly wrt /proc interfaces (switch create_proc_entry to proc_create(), get rid of the deprecated create_proc_read_entry() in favor of using proc_create_data() and seq_file etc). 7kloc removed. * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/viro/vfs: (204 commits) don't bother with deferred freeing of fdtables proc: Move non-public stuff from linux/proc_fs.h to fs/proc/internal.h proc: Make the PROC_I() and PDE() macros internal to procfs proc: Supply a function to remove a proc entry by PDE take cgroup_open() and cpuset_open() to fs/proc/base.c ppc: Clean up scanlog ppc: Clean up rtas_flash driver somewhat hostap: proc: Use remove_proc_subtree() drm: proc: Use remove_proc_subtree() drm: proc: Use minor->index to label things, not PDE->name drm: Constify drm_proc_list[] zoran: Don't print proc_dir_entry data in debug reiserfs: Don't access the proc_dir_entry in r_open(), r_start() r_show() proc: Supply an accessor for getting the data from a PDE's parent airo: Use remove_proc_subtree() rtl8192u: Don't need to save device proc dir PDE rtl8187se: Use a dir under /proc/net/r8180/ proc: Add proc_mkdir_data() proc: Move some bits from linux/proc_fs.h to linux/{of.h,signal.h,tty.h} proc: Move PDE_NET() to fs/proc/proc_net.c ...

2013-01-04wireless: add new wil6210 802.11ad 60GHz driverVladimir Kondratiev1-0/+603
This adds support for the 60 GHz 802.11ad Wilocity card through a new driver, wil6210. Wilocity implemented the firmware, QCA maintains the device driver. Currently supported: - STA: with security - AP: limited to 1 connected STA, security disabled - Monitor: due to a hardware/firmware limitation either control or non-control frames are monitored Using a STA and AP with this drive, one can assemble a fully functional BSS. Throughput of 1.2Gbps is achieved with iperf. The wil6210 cards have on-board flash memory for the firmware, the cards comes pre-flashed and no firmware download is required.
