When TPC is disabled IEEE80211_CONF_CHANGE_POWER event can be handled to
reconfigure HW's maximum txpower.
This fixes 0dBm txpower setting when user attaches to an interface for
the first time with the following scenario:
ieee80211_do_open()
ath9k_add_interface()
ath9k_set_txpower() /* Set TX power with not yet initialized
sc->hw->conf.power_level */
ieee80211_hw_config() /* Iniatilize sc->hw->conf.power_level and
raise IEEE80211_CONF_CHANGE_POWER */
ath9k_config() /* IEEE80211_CONF_CHANGE_POWER is ignored */
This issue can be reproduced with the following:
$ modprobe -r ath9k
$ modprobe ath9k
$ wpa_supplicant -i wlan0 -c /tmp/wpa.conf &
$ iw dev /* Here TX power is either 0 or 3 depending on RF chain */
$ killall wpa_supplicant
$ iw dev /* TX power goes back to calibrated value and subsequent
calls will be fine */

With multiple VIFS ath10k, and probably others, tries to find the
minimum txpower for all vifs and uses that when setting txpower in
the firmware.
If a second vif is added and starts to scan, it's txpower is not
initialized yet and it set to zero.
ath10k had a patch to ignore zero values, but then it is impossible
to actually set txpower to zero.
So, instead initialize the txpower to INT_MIN in mac80211, and let
drivers know that means the power has not been set and so should
be ignored.
This should fix regression in:

There really is no need to make drivers call the
ieee80211_start_tx_ba_cb_irqsafe() function and then
schedule the worker if all we want is to set a bit.
Add a new return value (that was previously considered
invalid) to indicate that the driver is immediately
ready for the session, and make drivers use it. The
only drivers that remain different are the Intel ones
as they need to negotiate more with the firmware.

We tried to revert commit d9c52fd17cb4 ("ath9k: fix tx99 with monitor
mode interface") but accidentally missed part of the locking change.
The lock has to be held earlier so that we're holding it when we do
"sc->tx99_vif = vif;" and also there in the current code there is a
stray unlock before we have taken the lock.

A couple of macros that deal with statistics in ath9k rely on the
declaration of the 'sc' variable, which they dereference.
However, when the statistics are disabled, the new instance in
ath_cmn_process_fft() causes a warning for an unused variable:
drivers/net/wireless/ath/ath9k/common-spectral.c: In function 'ath_cmn_process_fft':
drivers/net/wireless/ath/ath9k/common-spectral.c:474:20: error: unused variable 'sc' [-Werror=unused-variable]
It's better if those macros only operate on their arguments instead of
known variable names, and adding a cast to (void) kills off that warning.

Various documented examples on how to set up tx99 with ath9k rely
on setting up a regular monitor interface for setting the channel.
My previous patch "ath9k: fix tx99 with monitor mode interface" made
it possible to set it up this way again. However, it was removing support
for using an active monitor interface, which is required for controlling
the bitrate as well, since the bitrate is not passed down with a regular
monitor interface.
This patch partially reverts the previous one, but keeps support for using
a regular monitor interface to keep documented steps working in cases
where the bitrate does not matter

Tx99 is typically configured via a monitor mode interface, which does
not get added to the driver as a vif. Since the code currently expects
a configured virtual interface for tx99, enabling tx99 via debugfs fails.
Since the vif is not needed anyway, remove all checks for it.

There are specific cases, such as SAE authentication exchange, that
might require long duration to complete. For such cases, add support
for indicating to the driver the required duration of the prepare_tx()
operation, so the driver would still be able to complete the frame
exchange.
Currently, indicate the duration only for SAE authentication exchange,
as SAE authentication can take up to 2000 msec (as defined in IEEE
P802.11-REVmd D1.0 p. 3504).
As the patch modified the prepare_tx() callback API, also modify
the relevant code in iwlwifi.

Lockdep warns us that sc_pm_lock and cc_lock can cause a deadlock when
cc_lock is acquired by itself with interrupts enabled. Disable irqs
whenever taking cc_lock to avoid this.

The code currently relies on refcounting to disable IRQs from within the
IRQ handler and re-enabling them again after the tasklet has run.
However, due to race conditions sometimes the IRQ handler might be
called twice, or the tasklet may not run at all (if interrupted in the
middle of a reset).
This can cause nasty imbalances in the irq-disable refcount which will
get the driver permanently stuck until the entire radio has been stopped
and started again (ath_reset will not recover from this).
Instead of using this fragile logic, change the code to ensure that
running the irq handler during tasklet processing is safe, and leave the
refcount untouched.

This reworks the ath9k driver to schedule transmissions to connected
stations in a way that enforces airtime fairness between them. It
accomplishes this by measuring the time spent transmitting to or
receiving from a station at TX and RX completion, and accounting this to
a per-station, per-QoS level airtime deficit. Then, an FQ-CoDel based
deficit scheduler is employed at packet dequeue time, to control which
station gets the next transmission opportunity.
Airtime fairness can significantly improve the efficiency of the network
when station rates vary. The following throughput values are from a
simple three-station test scenario, where two stations operate at the
highest HT20 rate, and one station at the lowest, and the scheduler is
employed at the access point:
Before / After
Fast station 1: 19.17 / 25.09 Mbps
Fast station 2: 19.83 / 25.21 Mbps
Slow station: 2.58 / 1.77 Mbps
Total: 41.58 / 52.07 Mbps
The benefit of airtime fairness goes up the more stations are present.
In a 30-station test with one station artificially limited to 1 Mbps,
we have seen aggregate throughput go from 2.14 to 17.76 Mbps.

This switches ath9k over to using the mac80211 intermediate software
queueing mechanism for data packets. It removes the queueing inside the
driver, except for the retry queue, and instead pulls from mac80211 when
a packet is needed. The retry queue is used to store a packet that was
pulled but can't be sent immediately.
The old code path in ath_tx_start that would queue packets has been
removed completely, as has the qlen limit tunables (since there's no
longer a queue in the driver to limit).
The mac80211 intermediate software queues offer significant latency
reductions, and this patch allows ath9k to realise them. The exact gains
from this varies with the test scenario, but in an access point scenario
we have seen latency reductions ranging from 1/3 to as much as an order
of magnitude. We also achieve slightly better aggregation.
Median latency (ping) figures with this patch applied at the access point,
with two high-rate stations and one low-rate station (HT20 5Ghz), running
a Flent rtt_fair_var_up test with one TCP flow and one ping flow going to
each station:
Fast station Slow station
Default pfifo_fast qdisc: 430.4 ms 638.7 ms
fq_codel qdisc on iface: 35.5 ms 211.8 ms
This patch set: 22.4 ms 38.2 ms
Median aggregation sizes over the same test:
Default pfifo_fast qdisc: 9.5 pkts 1.9 pkts
fq_codel qdisc on iface: 11.2 pkts 1.9 pkts
This patch set: 13.9 pkts 1.9 pkts
This patch is based on Tim's original patch set, but reworked quite
thoroughly.

A regression was introduced in commit id 79d4db1214a ("ath9k: cleanup
led_pin initial") that broken the WLAN status led on my laptop with
AR9287 after suspending and resuming.
Steps to reproduce:
* Suspend (laptop)
* Resume (laptop)
* Observe that the WLAN led no longer turns ON/OFF depending on the
status and is always red
Even though for my case it only needs to be set to OUT in ath9k_start
but for consistency bring back the IN direction setting as well.

The use of config_enabled() against config options is ambiguous. In
practical terms, config_enabled() is equivalent to IS_BUILTIN(), but the
author might have used it for the meaning of IS_ENABLED(). Using
IS_ENABLED(), IS_BUILTIN(), IS_MODULE() etc. makes the intention
clearer.
This commit replaces config_enabled() with IS_ENABLED() where possible.
This commit is only touching bool config options.
I noticed two cases where config_enabled() is used against a tristate
option:
- config_enabled(CONFIG_HWMON)
[ drivers/net/wireless/ath/ath10k/thermal.c ]
- config_enabled(CONFIG_BACKLIGHT_CLASS_DEVICE)
[ drivers/gpu/drm/gma500/opregion.c ]
I did not touch them because they should be converted to IS_BUILTIN()
in order to keep the logic, but I was not sure it was the authors'
intention.

This patch fixes some issues with interface reconfiguration. It could
for example happen that an AP interface in beacon slot 0 was removed
leaving an IBSS station in one of the other slots. When this happens
the driver never sends out the beacon as it only tries to send a beacon
from slot 0.
Appart from that the tracking of required changes to the beacon config is
relatively complicated and prone to errors.
The approach taken here is to solve reconfiguration issues is to
reconfigure the beacons when any interface changes. This means that
the complexity of deciding whether an interface change may modify the
beacon configuration is gone. It also means that the beacon config will
be reliably updated when an interface is removed.
The issue that a single non-AP interface might not be in beacon
slot 0 and wouldn't be send out is solved by moving it into the
first slot. The TSF value in hardware is adjusted accordingly so
that the timestamp of the beacons stay consistent.

The removed ATH9K_SLOT_TIME_X constants simply map the value in microseconds
to the same integer. These constants were not used consistently, so fix the
inconsistency issue by replacing all occurances with the integer equivalent.

The ath9k driver modifies the TSF for VIFs for the purpose of sending
beacons in a staggered fashion. This patch exposes this VIF specific
adjustment of the TSF value to mac80211. Without the change the TSF
routines handle the hardware TSF value instead of the actual TSF value as
seen on the air.

The ath9k TSF handling routines need to be aware of the channel context that
is being modified. With this change the TSF related values that are stored
in each channel context will be correctly tracked and the harware will only
be updated if the modified context is currently the active one.
Without this change the TSF modifications done using these routines would
for example be lost during a hardware reset as done by ath_complete_reset.

This enum is already perfectly aliased to enum nl80211_band, and
the only reason for it is that we get IEEE80211_NUM_BANDS out of
it. There's no really good reason to not declare the number of
bands in nl80211 though, so do that and remove the cfg80211 one.

commit 61b559dea40e ("ath9k: add extra GPIO led support")
added ath9k to support access SOC's GPIOs, but implemented
in a separated API: ath9k_hw_request_gpio().
So this patch make the APIs more common, to support both
of WMAC and SOC GPIOs. The new APIs as below,
void ath9k_hw_gpio_request_in();
void ath9k_hw_gpio_request_out();
void ath9k_hw_gpio_free();
NOTE, the BSP of the SOC chips(AR9340, AR9531, AR9550, AR9561)
should set the corresponding MUX registers correctly.

Currently mac80211 does not inform the driver of the session
block ack timeout when starting a rx aggregation session.
Drivers that manage the reorder buffer need to know this
parameter.
Seeing that there are now too many arguments for the

This patch is derived from
commit 6301566e0b2d ("ath9k: export HW random number generator"),
We evaluated the entropy of the ADC data on QCA9531, QCA9561, QCA955x,
and AR9340, and it has sufficient quality random data (at least 10 bits
and up to 22 bits of min-entropy for a 32-bit value). We conservatively
assume the min-entropy is 10 bits out of 32 bits. Thus, ATH9K_RNG_BUF_SIZE
is set to 320 (u32) i.e., 1.25 kilobytes of data is inserted to fill up
the pool as soon as the entropy counter becomes 896/4096 (set by random.c).
Since ADC was not designed to be a dedicated HW RNG, we do not want to bind
it to /dev/hwrng framework directly. This patch feeds the entropy directly
from the WiFi driver to the input pool. The ADC register output is only
used as a seed for the Linux entropy pool. No conditioning is needed,
since all the conditioning is performed by the pool itself.

In other case I hit such warning on MIPS and

This support is essentially useless as typically networks are encrypted,
frames will be filtered by hardware, and rate scaling will be done with
the intended recipient in mind. For real monitoring of the network, the
monitor mode support should be used instead.
