* [PATCH v3 2/3] mac80211: Add airtime account and scheduling to TXQs
From: Toke Høiland-Jørgensen @ 2017-10-31 11:27 UTC (permalink / raw)
To: make-wifi-fast, linux-wireless; +Cc: Toke Høiland-Jørgensen
In-Reply-To: <20171027141451.22768-1-toke@toke.dk>
This adds airtime accounting and scheduling to the mac80211 TXQ
scheduler. A new hardware flag, AIRTIME_ACCOUNTING, is added that
drivers can set if they support reporting airtime usage of
transmissions. When this flag is set, mac80211 will expect the actual
airtime usage to be reported in the tx_time and rx_time fields of the
respective status structs.
When airtime information is present, mac80211 will schedule TXQs
(through ieee80211_next_txq()) in a way that enforces airtime fairness
between active stations. This scheduling works the same way as the ath9k
in-driver airtime fairness scheduling.

* [PATCH v3 1/3] mac80211: Add TXQ scheduling API
From: Toke Høiland-Jørgensen @ 2017-10-31 11:27 UTC (permalink / raw)
To: make-wifi-fast, linux-wireless; +Cc: Toke Høiland-Jørgensen
In-Reply-To: <20171027141451.22768-1-toke@toke.dk>
This adds an API to mac80211 to handle scheduling of TXQs and changes the
interface between driver and mac80211 for TXQ handling as follows:
- The wake_tx_queue callback interface no longer includes the TXQ. Instead,
the driver is expected to retrieve that from ieee80211_next_txq()
- Two new mac80211 functions are added: ieee80211_next_txq() and
ieee80211_schedule_txq(). The former returns the next TXQ that should be
scheduled, and is how the driver gets a queue to pull packets from. The
latter is called internally by mac80211 to start scheduling a queue, and
the driver is supposed to call it to re-schedule the TXQ after it is
finished pulling packets from it (unless the queue emptied).
The ath9k and ath10k drivers are changed to use the new API.

* [PATCH v3 3/3] ath9k: Switch to mac80211 airtime API
From: Toke Høiland-Jørgensen @ 2017-10-31 11:27 UTC (permalink / raw)
To: make-wifi-fast, linux-wireless; +Cc: Toke Høiland-Jørgensen
In-Reply-To: <20171027141451.22768-1-toke@toke.dk>
This removes the in-driver airtime fairness scheduling from ath9k and
switches the driver to use the API introduced in mac80211 in the
previous commit.

From: Karthik Ananthapadmanabha <karthida@marvell.com>
Fix the incorrect usage of rx_reorder_tbl_lock spinlock:
1. We shouldn't access the fields of the elements returned by
mwifiex_11n_get_rx_reorder_tbl() after we have released spin
lock. To fix this, To fix this, aquire the spinlock before
calling this function and release the lock only after processing
the corresponding element is complete.
2. Realsing the spinlock during iteration of the list and holding
it back before next iteration is unsafe. Fix it by releasing the
lock only after iteration of the list is complete.

From: Karthik Ananthapadmanabha <karthida@marvell.com>
Fix the incorrect usage of tx_ba_stream_tbl_lock spinlock:
1. We shouldn't access the fields of the elements returned by
mwifiex_get_ba_status() and mwifiex_get_ba_tbl(), after we have
released the spin lock. To fix this, aquire the spinlock before
calling these functions and release the lock only after
processing the correspnding element is complete.
2. Move tx_ba_stream_tbl_lock out of mwifiex_del_ba_tbl(), to
avoid recursive spinlock. Acquire the spinlock explicitly, before
calling mwifiex_del_ba_tbl().

Fix the incorrect usage of rx_pkt_lock spinlock. Realsing the
spinlock while the element is still in process is unsafe. The
lock must be released only after the element processing is
complete.

* [PATCH 0/3] mwifiex: fix usage issues with spinlocks

This patch series fixes issues with usage of few of the spinlocks
used by the driver. To summarise it fixes below issues:
1. Driver does access the elements returned by the list, without
acquiring the lock.
2. Driver release the lock during iteration of the list and hold
it back before starting the next iteration.
3. Driver release the lock while the element is still in process.

For ath10k issues please also CC ath10k list:
https://wireless.wiki.kernel.org/en/users/drivers/ath10k/support
And please copy the relevant errors from the logs to the email, faster
that way.

Unfortunately we have not published the firmware for this NIC yet.
I'll try to get an approval to publish it today (or latest by the end

It would be useful to specify which wireless card you are using. In

Hi,
We just have the Intel new WiFi module 9462NGW from Acer and tried
to verify if it works on the latest linux kernel. Unfortunately it
seems not even detected because the PCI ID seems unknown to the
iwlwifi driver. Then I add the following line to
drivers/net/wireless/intel/iwlwifi/pcie/drv.c
iwl_hw_card_ids
{IWL_PCI_DEVICE(0x31DC, 0x02A4, iwl9460_2ac_cfg)},
dmesg shows the following

It appears that both rtl8192cu and rtl8xxxu are being loaded for the

* [PATCH V2 9/9] qtnfmac: pass all CONNECT cmd params to wireless card for processing
From: igor.mitsyanko.os @ 2017-10-31 1:04 UTC (permalink / raw)
To: linux-wireless; +Cc: sergey.matyukevich.os, vulyanov, johannes
In-Reply-To: <20171031010455.27772-1-igor.mitsyanko.os@quantenna.com>
From: Igor Mitsyanko <igor.mitsyanko.os@quantenna.com>
Specifically, following parameters are needed for wireless device
configuration but were not available to it before:
- HT/VHT capabilities and capabilities masks.
- full channel info (not just IEEE number)
- BSSID hint
- previous BSSID for reassoc request
Move Management Frame Protection setting from common encr info
structure into STA-specific .connect command parameters.
Make sure that all new qlink structure definitions are alignment-safe.

* [PATCH V2 7/9] qtnfmac: configure and start AP interface with a single command
From: igor.mitsyanko.os @ 2017-10-31 1:04 UTC (permalink / raw)
To: linux-wireless; +Cc: sergey.matyukevich.os, vulyanov, johannes
In-Reply-To: <20171031010455.27772-1-igor.mitsyanko.os@quantenna.com>
From: Igor Mitsyanko <igor.mitsyanko.os@quantenna.com>
Current logic artificially divides "start AP" procedure into three
stages:
- generic interface configuration (security, channel etc)
- IE's processing
- enable AP mode on interface
This separation would not allow to do a proper device configuration as
first stage needs to use information from IEs that are processed on
a second stage. Which means first and second stages have to be meged.
In that case there is no point anymore to keep third stage either, so
merge all three into a single command.
This new command carries all the same info as contained in
"struct cfg80211_ap_settings".

"IE set" TLV carries the same information as

* [PATCH V2 4/9] qtnfmac: extend "IE set" TLV to include frame type info
From: igor.mitsyanko.os @ 2017-10-31 1:04 UTC (permalink / raw)
To: linux-wireless; +Cc: sergey.matyukevich.os, vulyanov, johannes
In-Reply-To: <20171031010455.27772-1-igor.mitsyanko.os@quantenna.com>
From: Igor Mitsyanko <igor.mitsyanko.os@quantenna.com>
Specifying frame type for "IE set" TLV will allow to use several
TLVs in a single message.
Modify users accordingly.

* [PATCH V2 1/9] qtnfmac: use per-band HT/VHT info from wireless device
From: igor.mitsyanko.os @ 2017-10-31 1:04 UTC (permalink / raw)
To: linux-wireless; +Cc: sergey.matyukevich.os, vulyanov, johannes
In-Reply-To: <20171031010455.27772-1-igor.mitsyanko.os@quantenna.com>
From: Igor Mitsyanko <igor.mitsyanko.os@quantenna.com>
HT/VHT capabilities must be reported per each band supported by a radio,
not for all bands on a radio. Furthermore, driver better not assume
any capabilities and just use whetever is reported by device itself.
To support this, convert "get channels" command into "get band info"
command. Difference is that it may also carry HT/VHT capabilities along
with channels information.
While at it, also add "num_bitrates" field to "get band info" command,
for future use.

* [PATCH V2 0/9] qtnfmac: allow to configure channel, BW, HT/VHT caps
From: igor.mitsyanko.os @ 2017-10-31 1:04 UTC (permalink / raw)
To: linux-wireless; +Cc: sergey.matyukevich.os, vulyanov, johannes
From: Igor Mitsyanko <igor.mitsyanko.os@quantenna.com>
This patchset has a goal to make operational parameters (channel, BW,
HT/VHT capabilities) configuration possible for qtnfmac driver.
It was part of bigger changeset when it was V1, rest are already applied.
Changelist V1->V2:
PATCH 8:
- fix a typo causing initialization of HT capabilities with VHT data.
Igor Mitsyanko (9):
qtnfmac: use per-band HT/VHT info from wireless device
qtnfmac: initialize HT/VHT caps "can override" masks
qtnfmac: get rid of PHYMODE capabilities flags
qtnfmac: extend "IE set" TLV to include frame type info
qtnfmac: SCAN results: retreive frame type information from "IE set"
TLV
qtnfmac: convert "Append IEs" command to QTN_TLV_ID_IE_SET usage
qtnfmac: configure and start AP interface with a single command
qtnfmac: include HTCAP and VHTCAP into config AP command
qtnfmac: pass all CONNECT cmd params to wireless card for processing
