| * | | | mwifiex: add get_antenna support for cfg80211Shengzhen Li2016-07-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since commit de3bb771f471 ("cfg80211: add more warnings for inconsistent ops") the wireless core warns if a driver implements a cfg80211 callback but doesn't implements the inverse operation. The mwifiex driver defines a .set_antenna handler but not a .get_antenna so this not only makes the core to print a warning when creating a new wiphy but also the antenna isn't reported to user-space apps such as iw. This patch queries the antenna to the firmware so is properly reported to user-space. With this patch, the wireless core does not warn anymore and: $ iw phy phy0 info | grep Antennas Available Antennas: TX 0x3 RX 0x3 Configured Antennas: TX 0x3 RX 0x3 Signed-off-by: Shengzhen Li <szli@marvell.com> Signed-off-by: Amitkumar Karwar <akarwar@marvell.com> [javier: expand the commit message] Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Tested-by: Enric Balletbo i Serra <enric.balletbo@collabora.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
| * | | | mwifiex: add a cfg80211 .get_tx_power operation callbackJavier Martinez Canillas2016-07-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The mwifiex driver implements a cfg80211 .set_tx_power operation handler but doesn't have the inverse .get_tx_power callback. This not only has the effect that the Tx power can't be reported to user space tools such as iwconfig and iwlist but also that the wireless core prints a warning when a new wiphy is created due an cfg80211 operation being implemented without its counterpart. After this patch, the Tx power is properly reported to user-space tools: $ iwlist mlan0 txpower mlan0 unknown transmit-power information. Current Tx-Power=13 dBm (19 mW) and also the following warning isn't shown anymore on the driver probe: WARNING: CPU: 3 PID: 127 at net/wireless/core.c:366 wiphy_new_nm+0x66c/0x6ac Modules linked in: mwifiex_sdio mwifiex CPU: 3 PID: 127 Comm: kworker/3:1 Tainted: G W 4.7.0-rc1-next-20160531-00006-g569df5b983f3 Hardware name: SAMSUNG EXYNOS (Flattened Device Tree) Workqueue: events request_firmware_work_func [<c010e1ac>] (unwind_backtrace) from [<c010af38>] (show_stack+0x10/0x14) [<c010af38>] (show_stack) from [<c0323b9c>] (dump_stack+0x88/0x9c) [<c0323b9c>] (dump_stack) from [<c011a828>] (__warn+0xe8/0x100) [<c011a828>] (__warn) from [<c011a8f0>] (warn_slowpath_null+0x20/0x28) [<c011a8f0>] (warn_slowpath_null) from [<c06a42d4>] (wiphy_new_nm+0x66c/0x6ac) [<c06a42d4>] (wiphy_new_nm) from [<bf1c24cc>] (mwifiex_register_cfg80211+0x28/0x3f0 [mwifiex]) [<bf1c24cc>] (mwifiex_register_cfg80211 [mwifiex]) from [<bf1a0018>] (mwifiex_fw_dpc+0x2b0/0x474 [mwifiex]) [<bf1a0018>] (mwifiex_fw_dpc [mwifiex]) from [<c040eb74>] (request_firmware_work_func+0x30/0x58) [<c040eb74>] (request_firmware_work_func) from [<c012fe90>] (process_one_work+0x124/0x338) [<c012fe90>] (process_one_work) from [<c01300dc>] (worker_thread+0x38/0x4d4) [<c01300dc>] (worker_thread) from [<c01353b8>] (kthread+0xdc/0xf4) [<c01353b8>] (kthread) from [<c0107978>] (ret_from_fork+0x14/0x3c) Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Tested-by: Enric Balletbo i Serra <enric.balletbo@collabora.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>

But the patch didn't check the return value of the functions doing the firmware calls and returned an error even if the functions didn't fail.

If driver writes RBD registers while MAC is asleep the values are stored in shadow registers to be copied whenever MAC wakes up. However, in 9000 devices a MAC wakeup is not triggered and when the bus powers down due to inactivity the shadow values and dirty bits are lost. Turn on the chicken-bits that cause MAC wakeup for RX-related values as well when the device is in D0. When the device is in low power mode turn the RX wakeup chicken bits off since driver is idle and this W/A is not needed. Remove previous W/A which was ineffective.

The reason is that NSSN advances on the first sub-frame, and may cause the reorder buffer to advance before all the sub-frames arrive. Example: Reorder buffer contains SN 0 & 2. We receive AMSDU with SN 1 and NSSN for first sub frame 3. The result us that driver releases SN 0,1, 2. When sub-frame 1 arrives - reorder buffer is already ahead and it will be dropped. If the last sub-frame is not on this queue - we will get frame release notification with up to date NSSN.

This means that we can advertise the maximal size of A-MSDUs regardless of the receive buffer's size. In order to be able to forcefully use a lower A-MSDU size, add a default value for the module parameter. Pre-9000 will have a default of 4K, and 9000 will have 12K. Setting the amsdu_size module parameter to 4K will limit the A-MSDU on 9000 as well.

On success firmware triggers an event and driver's handler removes a matching interface. However on event timeout we remove interface directly from the cfg80211 callback.

A dedicated workqueue has been used since the workitem (viz &priv->cmd_work per priv, which maps to lbtf_cmd_work) is involved in actual command processing and may be used on a memory reclaim path. The workitems require forward progress under memory pressure and hence, WQ_MEM_RECLAIM has been set. Since there are only a fixed number of work items, explicit concurrency limit is unnecessary here.

This way it's easier to follow requested array length as it's immediately followed by code filling it. It's easier to check e.g. why we need 4 entries for P2P. Other than that it deduplicates some checks (e.g. for P2P). 2) It reorders code to first prepare limits and then define a new combo. Previously this was mixed (e.g. we were setting num of channels before preparing limits). 3) It modifies mbss code to use i variable just like other combos do.

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).

This patch enables wmediumd to attach from non-initial network namespaces using a user namespace having CAP_NET_ADMIN. A registered wmediumd can forward frames on radios that have been created in the same network namespace, even if they have been moved to other network namespaces. The wmediumd Netlink portid is tracked per net namespace. Additionally, the portid is stored on all radios created in that net namespace to simplify the portid lookup in the data path.
